All-transレチノイン酸は腸管ナトリウム依存性リン酸トランスポーター遺伝子(Npt2b)の転写を負に制御する,
日本ビタミン学会, 2020年11月.

(要約): ビタミン欠乏(VAD)ラットにall-transレチノイン酸(ATRA)を投与後，腸管のNpt2b発現を中心としたリン吸収への影響と，ラットNpt2b遺伝子プロモーターを用いたATRAによるNpt2b生化学転写調節機構について検討した．VADラットにATRAを腹腔内投与した18時間後，血漿リン濃度はビタミンAによる影響を認めなかったが，腸管リン酸取り込み活性，Npt2b蛋白発現量およびmRNA発現量はATRA投与により抑制された．マウス胎児線維芽細胞株NIH3T3細胞を用いたルシフェラーゼアッセイの結果，レチノイン酸受容体(RAR)/レチノイドX受容体存在下においてATRAおよびRARアゴニスト濃度依存的にNpt2b遺伝子プロモーター活性は低下した．デリーションアッセイの結果，ATRAによるNpt2b遺伝子プロモーター活性の低下は，転写因子CCAAT/enhancer-binding protein(C/EBP)依存的であることが示唆された．

Necessity of daily 1000-IU vitamin D supplementation for maintaining a sufficient vitamin D status.,
The Journal of Medical Investigation : JMI, Vol.69, No.1.2, 135-140, 2022.

(要約): The changes in the serum 25-hydroxyvitamin D (25(OH)D) concentrations after daily 1000-IU vitamin D intake for 3 months (3-month-VD), 6 months (6-month-VD) and then 6-month cessation of vitamin D in-take (6-month-VD cessation) were examined. The serum 25(OH)D levels in 11 male and 16 female subjects were 12.1±3.5 ng/mL at baseline, increased to 27.1±4.7 ng/mL at 3-month-VD, 28.5±5.1 ng/mL at 6-month-VD and decreased to 16.4±4.0 ng/mL at 6-month-VD cessation. The present study suggested that a vitamin D intake of 1000 IU/day is required to maintain the 25(OH) D concentration at 30 ng/mL or higher without vitamin D intoxication. J. Med. Invest. 69 : 135-140, February, 2022.

Cut-off values for skeletal muscle strength and physical functions in Japanese elderly with walking difficulty.,
The Journal of Medical Investigation : JMI, Vol.68, No.1.2, 48-52, 2021.

(要約): Age-related changes in muscle strength and physical functions, and the association between vitamin D status and skeletal muscle functions were investigated in 36 men (21-90 years old) and 52 women (21-104 years old). Significant ageing-related decreases in several skeletal muscle functions and serum 25-hydroxyvitamin D [25(OH)D] levels were observed in both men and women. Cut-off values for the Timed up and go (TUG) test, walking speed, handgrip strength and Barthel Index (BI) detecting walking difficulties in the receiver operating characteristic (ROC) analysis were 11.1 sec, 0.60 m / sec, 17.0 kg, and 90.0 in males, and 28.6 sec, 0.43 m / sec, 13.9 kg, and 67.5 in females, respectively. By comparing personal present data of muscle strength with these cut-off values, people can easily understand their process to walking difficulty. Therefore, these results are important and useful to avoid or to delay a handicapped and dependent status by improving the vitamin D level, rehabilitation and nursing care. J. Med. Invest. 68 : 48-52, February, 2021.

Effects of daily 1,000-IU vitamin D-fortified milk intake on skeletal muscle mass, power, physical function and nutrition status in Japanese.,
The Journal of Medical Investigation : JMI, Vol.68, No.3.4, 249-255, 2021.

(要約): An intervention study was conducted to investigate the effects of daily 1,000-IU vitamin D-fortified milk intake on skeletal muscle mass, power, physical function and nutrition status in 26 healthy people and 8 older adults living in a nursing home. The serum 25-hydroxyvitamin D [25(OH)D] level was 13.4 ± 0.8 ng / mL and it markedly increased to 29.6 ± 0.9 ng / mL after daily 1000-IU vitamin D-fortified milk intake for 6 months. Handgrip strength (kg) also significantly increased in the 21-50 years and total groups, and male subjects, and the timed up and go test signiﬁcantly improved in the 21-50 years and total groups, and female subjects after 6-month vitamin D intake. However, there were no significant differences between baseline and post-treatment in the Barthel Index (BI), walking speed (m / sec) or skeletal muscle mass (kg, % of BW, kg / m2). Therefore, the present study suggested that vitamin D-fortified milk intake is effective at improving muscle strength and physical function in Japanese, although further studies are needed, particularly for older adults.

All-trans retinoic acid reduces the transcriptional regulation of intestinal sodium-dependent phosphate co-transporter gene (Npt2b).,
The Biochemical Journal, Vol.477, No.4, 817-831, 2020.

(要約): Inorganic phosphate (Pi) homeostasis is regulated by intestinal absorption via type II sodium-dependent co-transporter (Npt2b) and by renal reabsorption via Npt2a and Npt2c. Although we previously reported that vitamin A-deficient (VAD) rats had increased urine Pi excretion through the decreased renal expression of Npt2a and Npt2c, the effect of vitamin A on the intestinal Npt2b expression remains unclear. In this study, we investigated the effects of treatment with all-trans retinoic acid (ATRA), a metabolite of vitamin A, on the Pi absorption and the Npt2b expression in the intestine of VAD rats, as well as and the underlying molecular mechanisms. In VAD rats, the intestinal Pi uptake activity and the expression of Npt2b were increased, but were reduced by the administration of ATRA. The transcriptional activity of reporter plasmid containing the promoter region of the rat Npt2b gene was reduced by ATRA in NIH3T3 cells overexpressing retinoic acid receptor (RAR) and retinoid X receptor (RXR). On the other hand, CCAAT/enhancer-binding proteins (C/EBP) induced transcriptional activity of the Npt2b gene. Knockdown of the C/EBP gene and a mutation analysis of the C/EBP responsible element in the Npt2b gene promoter indicated that C/EBP plays a pivotal role in the regulation of Npt2b gene transcriptional activity by ATRA. EMSA revealed that the RAR/RXR complex inhibits binding of C/EBP to Npt2b gene promoter. Together, these results suggest that ATRA may reduce the intestinal Pi uptake by preventing C/EBP activation of the intestinal Npt2b gene.

Relationship between age-related decreases in serum 25-hydroxyvitamin D levels and skeletal muscle mass in Japanese women.,
The Journal of Medical Investigation : JMI, Vol.67, No.1.2, 151-157, 2020.

(要約): A clearer understanding of skeletal muscle mass (SMM) in middle-aged and elderly individuals is important for maintaining functionality. In the present study, age-related changes in SMM, the threshold of SMM with walking difficulty, intestinal nutrient absorption rate, and various serum factors were examined in Japanese populations of different ages. We used 24-h creatinine excretion as a measure of total body SMM. Age-related decreases in SMM, intestinal nutrient absorption rates, and serum 25-hydroxyvitamin D [25(OH)D] concentrations were significantly higher in women than in men. The cut-off values for SMM (kg), its percentage of total body weight (BW), the SMM index [SMMI] (Kg / m2), and creatinine height index (CHI) (%) in elderly individuals with walking difficulty were approximately 8-10 kg, 17-20% of BW, 3.9-4.6 kg / m2, and 44%, respectively. Serum 25(OH)D concentrations were closely associated with SMM (kg, % of BW, kg / m2) and CHI (%) as well as the intestinal absorption rates of nitrogen (%) and phosphorus (%) in women, but not in men. The present results demonstrate that vitamin D is an important metabolic factor in skeletal muscle, and contributes to the optimal management of skeletal muscle and the prevention of sarcopenia. J.

Association of increased renal Cyp24a1 gene expression with low plasma 1,25-dihydroxyvitamin D levels in rats with streptozotocin-induced diabetes.,
Journal of Clinical Biochemistry and Nutrition, Vol.66, No.1, 49-56, 2019.

(要約): Decreases in plasma vitamin D concentrations have been reported in diabetes, although the mechanism involved in this decrease is unclear. Here, we investigated the association between Cyp24a1, a vitamin D catabolic enzyme, and abnormalities in vitamin D metabolism in streptozotocin-induced diabetes rats, an animal model of type 1 diabetes. Plasma 1,25-dihydroxyvitamin D [1,25(OH)2D] levels were significantly lower in streptozotocin-induced diabetes rats and renal Cyp24a1 mRNA expression levels were increased. Western blotting analysis of streptozotocin-induced diabetes rats kidney tissues with anti-CYP24A1 antibody showed a strong signal around 40 kDa, which differs from the predicted 50-55 kDa molecular weight for full-length Cyp24a1 and could represent the Cyp24a1-splicing variant that lacks exons 1 and 2. We observed high levels of renal Cyp24a1-splicing variant mRNA expression in streptozotocin-induced diabetes rats. We also confirmed transcriptional up-regulation of endogenous Cyp24a1 mRNA expression through glucocorticoid receptors by glucocorticoid in opossum kidney proximal cells. Taken together, our results indicated that high Cyp24a1 expression levels may play a role in the decrease of plasma 1,25(OH)2D levels in streptozotocin-induced diabetes rats. High plasma corticosterone levels in diabetes may affect transcriptional regulation to promote increases in Cyp24a1 expression.

Skeletal muscle mass of old Japanese women suffering from walking difficulty in nursing home.,
The Journal of Medical Investigation : JMI, Vol.65, No.1.2, 122-130, 2018.

(要約): By using 24 hour urinary creatinine levels, skeletal muscle mass (kg), its rate (%) of body weight and creatinine height index (%) were determined in old Japanese women suffering from walking difficulty in nursing home and compare with those of young university students. Those of old subjects showed approximately 30-50%, 36-44% and 44-46% of young subjects, respectively. It is suggested that these values are important and useful biomarkers for the planning and the achievement of rehabilitation program for the maintaining and restoring skeletal muscle mass and for the careful support by registered care workers to aged persons.

Dietary phosphate exacerbates intestinal inflammation in experimental colitis.,
Journal of Clinical Biochemistry and Nutrition, Vol.61, No.2, 91-99, 2017.

(要約): study, the effects of phosphate on proinflammatory cytokine induction and reactive oxygen species production in RAW264.7 macrophage were examined. Dietary phosphate exacerbated intestinal inflammation in experimental colitis in a dose-dependent manner, as assessed by the clinical disease activity score, colon length, and histology. Furthermore, the high phosphate diet increased myeloperoxidase activity and proinflammatory cytokine mRNA expression through the activation of nuclear factor B in the inflamed colon. In addition, high phosphate loading in RAW264.7 cells directly enhanced reactive oxygen species production and proinflammatory cytokine gene expression. Our results demonstrated that the high phosphate diet exacerbated intestinal inflammation in experimental colitis. These findings have important therapeutic implications for inflammatory bowel disease patients.

Single vegetable meal content equivalence and alternative to fat for satiety: a randomised trial in Japanese women,
Asia Pacific Journal of Clinical Nutrition, Vol.25, No.3, 478-486, 2016.

(要約): Although high energy density foods are highly palatable, their overconsumption leads to obesity because of high fat content. Low energy density foods are more effective for preventing individuals from becoming overweight. We investigated how different amounts of a single vegetable affect the sensory properties of meals with different energy densities. In a randomized crossover design, 40 young Japanese women consumed control and high-fat (HF) lunches. Control meals contained the same amount of rice and hamburger and 80 g (C80), 120 g (C120), 160 g (C160), 200 g (C200), 240 g (C240), or 280 g (C280) of broccoli. HF meals were control meals to which 38.1 g of oil was added (HF80, HF120, HF160, HF200, HF240, and HF280). Sensory properties before intake and 0.5, 1, 2, 3, 4, and 5 h after meals were assessed using a visual analog scale. Fullness was significantly lower with C80 than with C200 and C280 at 0.5 h and all time points, respectively, after consumption. In contrast, satisfaction with all HF meals was similar at all time points. Fullness and satisfaction were higher with almost all HF meals than with control meals; however, fullness and satisfaction were similar between HF200 and all control meals 1-4 h after consumption. Fat increases satiety when a single vegetable is included in the meal; however, at least of 200 g of vegetable in a 500- kcal meal with low fat content provides fullness and satisfaction similar to those provided by an HF meal.

Effects of dietary phosphate on glucose and lipid metabolism.,
American Journal of Physiology, Endocrinology and Metabolism, Vol.310, No.7, E526-E538, 2016.

(要約): Recent epidemiological and animal studies have suggested that excess intake of phosphate (Pi) is a risk factor for the progression of chronic kidney disease and its cardiovascular complications. However, little is known about the impact of dietary high Pi intake on the development of metabolic disorders such as obesity and type II diabetes. In this study, we investigated the effects of dietary Pi on glucose and lipid metabolism in healthy rats. Male, 8-wk-old Sprague-Dawley rats were divided into 3 groups and given experimental diets containing varying amounts of Pi, i.e. 0.2% (low Pi, LP), 0.6% (control Pi, CP), and 1.2% (high Pi, HP). After 4 weeks, HP group showed lower visceral fat accumulation compared with other groups, accompanied by a low respiratory exchange ratio (VCO2/VO2) without alteration of locomotive activity. HP group had lower levels of plasma insulin and non-esterified fatty acids. In addition, HP group also showed suppressed expression of hepatic lipogenic genes including sterol regulatory element binding protein-1c, fatty acid synthase, and acetyl-CoA carboxylase, whereas there was no difference in hepatic fat oxidation among the groups. On the other hand, uncoupling protein 1 (UCP1) and peroxisome proliferator-activated receptor gamma coactivator alpha (PGC1) expression were significantly increased in the brown adipose tissue (BAT) of HP group. Our data demonstrated that a high Pi diet can negatively regulate lipid synthesis in the liver, and increased mRNA expression related to lipid oxidation and UCP1 in BAT, thereby preventing visceral fat accumulation. Thus, dietary Pi is a novel metabolic regulator.

Dietary phosphate supplementation delays the onset of iron deficiency anemia and affects iron status in rats.,
Nutrition Research, Vol.35, No.11, 1016-1024, 2015.

(要約): Inorganic phosphate (Pi) plays critical roles in bone metabolism and is an essential component of 2,3-diphosphoglycerate (2,3-DPG). It has been reported that animals fed a low-iron diet modulate Pi metabolism, whereas the effect of dietary Pi on iron metabolism, particularly in iron deficiency anemia (IDA), is not fully understood. In this study, we hypothesized the presence of a link between Pi and iron metabolism and tested the hypothesis by investigating the effects of dietary Pi on iron status and IDA. Wistar rats aged 4 weeks were randomly assigned to 1 of 4 experimental dietary groups: normal iron content (Con Fe)+0.5% Pi, low-iron (Low Fe)+0.5% Pi, Con Fe+1.5% Pi, and Low Fe+1.5% Pi. Rats fed the 1.5% Pi diet for 14 days, but not for 28 days, maintained their anemia state and plasma erythropoietin concentrations within the reference range, even under conditions of low iron. In addition, plasma concentrations of 2,3-DPG were significantly increased by the 1.5% Pi diets and were positively correlated with plasma Pi concentration (r=0.779; P<.001). Dietary Pi regulated the messenger RNA expression of iron-regulated genes, including divalent metal transporter 1, duodenal cytochrome B, and hepcidin. Furthermore, iron concentration in liver tissues was increased by the 1.5% Pi in Con Fe diet. These results suggest that dietary Pi supplementation delays the onset of IDA and increases plasma 2,3-DPG concentration, followed by modulation of the expression of iron-regulated genes.

Effect of nutritional counseling and long term isomaltulose based liquid formula (MHN-01) intake on metabolic syndrome.,
Journal of Clinical Biochemistry and Nutrition, Vol.57, No.2, 140-144, 2015.

(要約): The isomaltulose based liquid formula (MHN-01), suppresses postprandial plasma glucose and insulin levels in healthy persons and patients with impaired glucose tolerance (IGT) or type 2 diabetes. MHN-01 intake as a part of breakfast also suppresses glucose and insulin levels after lunch, suggesting second meal effect. The objective of this study was to investigate the effects of nutritional counseling and long-term (24 weeks) MHN-01 ingestion on biomarkers of metabolic syndrome. Forty-one subjects with criteria of metabolic syndrome participated in this study composed with the control period (0-12 week) followed by nutritional counseling and the experimental period (12-36 week) followed by 200 kcal (837 kJ) of MHN-01 or dextrin-based standard balanced liquid formula (SBF) loading as a part of breakfast. In 16 of 41 subjects became to out of criteria for liquid formula loading study during control period (unqualified group). In the unqualified group, several biomarkers were improved. In experimental period, serum HbA1c levels significantly increased in SBF group (n = 12) but did not change in MHN-01 group (n = 10). Thus, intake of 837 kJ MHN-01 as a part of breakfast may be effective for suppression of deteriorating glucose metabolism in metabolic syndrome.

Recovery of nutritional metabolism after liver transplantation,
Nutrition, Vol.31, No.1, 105-110, 2015.

(要約): Perioperative nutritional assessment is critically important to reflect nutritional management because liver transplantation (LTx) often is undertaken in patients with poor nutritional status. The aim of this study was to evaluate nutritional status, including the non-protein respiratory quotient (npRQ), resting energy expenditure (REE), nitrogen balance, and blood biochemical parameters in patients before and after LTx. Fourteen patients undergoing LTx and 10 healthy controls were enrolled in this study. The npRQ and REE were measured using indirect calorimetry before LTx and at 2, 3, and 4 wk after the procedure. Blood biochemistry and nitrogen balance calculated by 24-h urine collection were performed concurrently with indirect calorimetric measurement; the results were compared between the two groups. Before LTx, npRQ was significantly lower and serum non-esterified fatty acid levels were significantly higher in the patients than in the controls. Furthermore, a negative nitrogen balance was observed in the patients. These, however, improved significantly at 4 wk after LTx. REE did not significantly increase compared with the preoperative values in recipients. Blood biochemistry showed gradually increasing levels of serum cholinesterase and albumin. These failed to reach to normal levels by 4 wk post-transplant. The findings revealed that improvement of nutritional metabolism after LTx may require 4 wk. Additional nutritional strategies, therefore, may be needed to minimize catabolic state during the early post-transplant period. Adequate, individualized nutritional guidance before and after LTx should be performed in these patients.

Niacin and Chronic Kidney Disease.,
Journal of Nutritional Science and Vitaminology, Vol.61 Suppl, S173-5, 2015.

(要約): Chronic kidney disease (CKD) is an increasing problem worldwide. The number of end-stage renal disease patients requiring treatment by dialysis is estimated to be increasing by 10,000 patients per year in Japan. Furthermore, an estimated 13 million people are living with CKD in Japan. Various complications are associated with CKD, including cardiovascular disease (CVD). More than one-third of CKD patients die from CVD. Thus, prevention of CVD is a primary concern for the treatment of CKD patients. CKD-mineral and bone disorder (CKD-MBD) is a serious complication that typically leads to CVD. Hyperphosphatemia is thought to be a central-risk factor for CKD-MBD. Therefore, managing hyperphosphatemia is crucial to prevent CKD-MBD and CVD. It is difficult to achieve the target serum phosphate level through dietary modifications alone in patients with hyperphosphatemia, because most foods contain phosphate. Thus, phosphate binders such as calcium carbonate are commonly prescribed to CKD patients with hyperphosphatemia, but these have undesirable side effects. Inhibition of intestinal phosphate transport activity has also been investigated as an alternative approach for controlling serum phosphate levels in CKD patients. Nicotinamide, which is the amide of niacin, can inhibit intestinal phosphate transport. Niacin and related compounds have also been developed as drugs for hyperlipidemia conditions, especially hypertriglyceridemia with low high-density lipoprotein. This type of dyslipidemia is frequently observed in CKD patients and is a modifiable risk factor for CVD. Thus, niacin and related compounds may have utility for the treatment of both hyperphosphatemia and dyslipidemia in CKD patients to prevent CVD.

Fluctuating plasma phosphorus level by changes in dietary phosphorus intake induces endothelial dysfunction.,
Journal of Clinical Biochemistry and Nutrition, Vol.56, No.1, 35-42, 2014.

(要約): High serum phosphorus (P) impairs endothelial function by increasing oxidative stress and decreasing nitric oxide production. Serum P levels fluctuate due to circadian rhythms or dietary P intake in healthy people and due to dialysis in end-stage chronic kidney disease patients. Here we examined whether fluctuating plasma P caused by changes in dietary P intake may be involved in endothelial dysfunction, resulting in increased cardiovascular risk. Rats were fed a diet containing 0.6% P for 16 days (control group), or a diet alternating between 0.02% P and 1.2% P (LH group) or between 1.2% P and 0.02% P (HL group) every 2 days; the total amount of P intake among the groups during the feeding period was similar. In the LH and HL groups, endothelial-dependent vasodilation significantly decreased plasma 8-(OH)dG level significantly increased, and the expression of inflammatory factors such as MCP-1 increased in the endothelium as compared with the control group. These data indicate that repetitive fluctuations of plasma P caused by varying dietary P intake can impair endothelial function via increased oxidative stress and inflammatory response. Taken together, these results suggest that habitual fluctuation of dietary P intake might be a cause of cardiovascular disease through endothelial dysfunction, especially in chronic kidney disease patients.

High-fat diet-related stimulation of sweetness desire is greater in women than in men despite high vegetable intake,
Public Health Nutrition, Vol.18, No.7, 1272-1281, 2014.

(要約): To examine the effects of lunches with different dietary energy densities on food preferences between genders. Randomized crossover study. Participants were administered the following packed test meals once weekly on a specified day during six sessions: control (150 g of rice with a sautéed beef entrée containing 40 g of raw beef and 240 g of vegetables), high-meat/low-rice, low-vegetable, medium-fat/low-vegetable, high-fat and high-fat/low-vegetable meals. Subjective levels of sensory properties were assessed over time using visual analogue scales. University of Tokushima Graduate School, Tokushima, Japan. Sixty-five men and sixty-five women matched by age and BMI. Men showed significantly stronger desires for salty and fatty foods after meals (P<0·05). Women showed a significantly stronger desire for sweetness from 2 h after the low-vegetable meal, and increasing fat content under high-vegetable conditions caused a significant stimulated sweetness desire in women more than in men (P<0·05). Moreover, after a high-meat/low-rice meal with 100 g of rice, sweetness desire was stronger in women (P=0·024), whereas no significant differences in sweetness desire were shown between genders after another low-energy-density control meal with 150 g of rice. Men had significantly stronger desires for salty and fatty foods, whereas women preferred sweet food after meals. The sweetness desire in women was stimulated by increasing fat content, even with a high vegetable intake. Low rice intake in a low-energy-density diet also caused a relative stimulation of sweetness desire in women.

Dietary combination of sucrose and linoleic acid causes skeletal muscle metabolic abnormalities in Zucker fatty rats through specific modification of fatty acid composition.,
Journal of Clinical Biochemistry and Nutrition, Vol.55, No.1, 15-25, 2014.

(要約): A dietary combination of sucrose and linoleic acid strongly contributes to the development of metabolic disorders in Zucker fatty rats. However, the underlying mechanisms of the metabolic disorders are poorly understood. We hypothesized that the metabolic disorders were triggered at a stage earlier than the 8 weeks we had previously reported. In this study, we investigated early molecular events induced by the sucrose and linoleic acid diet in Zucker fatty rats by comparison with other combinations of carbohydrate (sucrose or palatinose) and fat (linoleic acid or oleic acid). Skeletal muscle arachidonic acid levels were significantly increased in the sucrose and linoleic acid group compared to the other dietary groups at 4 weeks, while there were no obvious differences in the metabolic phenotype between the groups. Expression of genes related to arachidonic acid synthesis was induced in skeletal muscle but not in liver and adipose tissue in sucrose and linoleic acid group rats. In addition, the sucrose and linoleic acid group exhibited a rapid induction in endoplasmic reticulum stress and abnormal lipid metabolism in skeletal muscle. We concluded that the dietary combination of sucrose and linoleic acid primarily induces metabolic disorders in skeletal muscle through increases in arachidonic acid and endoplasmic reticulum stress, in advance of systemic metabolic disorders.

Estimate of dietary phosphorus intake using 24-h urine collection.,
Journal of Clinical Biochemistry and Nutrition, Vol.55, No.1, 62-66, 2014.

(要約): Increases in serum phosphorus levels and dietary phosphorus intake induces vascular calcification, arterial sclerosis and cardiovascular diseases. Limiting phosphorus intake is advisable, however, no assessment methods are capable of estimating dietary phosphorus intake. We hypothesized that urinary phosphorus excretion can be translated into estimation of dietary phosphorus intake, and we evaluated whether a 24-h urine collection method could estimate dietary phosphorus intake. Thirty two healthy subjects were recruited for this study. Subjects collected urine samples over 24 h and weighed dietary records. We calculated dietary protein intake and phosphorus intake from dietary records and urine collection, and investigated associations between the two methods in estimating protein and phosphorus intake. Significant positive correlations were observed between dietary records and UC for protein and phosphorus intake. The average intakes determined from dietary records were significantly higher than from urine collection for both protein and phosphorus. There was a significant positive correlation between both the phosphorus and protein difference in dietary records and urine collection. The phosphorus-protein ratio in urine collection was significantly higher than in dietary records. Our data indicated that the 24-h urine collection method can estimate the amount of dietary phosphorus intake, and the results were superior to estimation by weighed dietary record.

The aim of this study was to determine differences in energy metabolism, blood biochemistry, and nutritional status before and after liver resection in patients with hepatocellular carcinoma (HCC) and healthy living donors for liver transplantation. Eighteen hospitalized patients with HCC group and 13 living donors for liver transplantation (donor group) were enrolled in this study. The donor group was divided into two groups on the basis of age; Y-donor group (age < 40 y, n = 7), and O-donor group (age ≥ 40 y, n = 6). Energy metabolism was measured by indirect calorimetry at preoperative day and postoperative day (POD) 7 and 14, and blood biochemistry was also examined. Recovery of non-protein respiratory quotient (npRQ) and blood biochemical data such as total bilirubin, aspartate aminotransferase and alanine aminotransferase levels were observed in Y-donor group on POD 14. However, although biochemical data improved in the HCC and O-donor group, npRQ remained unchanged on POD 14. Improvement of npRQ took longer than blood biochemical data in patients with HCC and older donors. Because the recovery of npRQ is associated with donor age, careful nutritional management may be required for a longer time depending on the pathophysiological condition of each patient after hepatectomy.

Short-term dietary phosphate restriction up-regulates ileal fibroblast growth factor 15 gene expression in mice.,
Journal of Clinical Biochemistry and Nutrition, Vol.54, No.2, 102-108, 2014.

(要約): Members of the fibroblast growth factor (FGF) 19 subfamily, including FGF23, FGF15/19, and FGF21, have a role as endocrine factors which influence the metabolism of inorganic phosphate (Pi) and vitamin D, bile acid, and energy. It has been reported that dietary Pi regulates circulating FGF23. In this study, the short-term effects of dietary Pi restriction on the expression of FGF19 subfamily members in mice were analyzed. An initial analysis confirmed plasma FGF23 levels positively correlated with the amount of dietary Pi. On the other hand, ileal Fgf15 gene expression, but not hepatic Fgf21 gene expression, was up-regulated by dietary Pi restriction. In addition, we observed the increase of plasma 1,25-dihydroxyvitamin D [1,25(OH)2D] levels by dietary Pi restriction, and the up-regulation of ileal Fgf15 mRNA expression by 1,25(OH)2D3 and vitamin D receptor (VDR). Importantly, dietary Pi restriction-induced Fgf15 gene expression was prevented in VDR-knockout mice. Furthermore, diurnal variations of plasma triglyceride concentrations and hepatic mRNA expression of the bile acid synthesis enzyme Cyp7a1 as one of Fgf15 negative target genes was influenced by dietary Pi restriction. These results suggest that dietary Pi restriction up-regulates ileal Fgf15 gene expression through 1,25(OH)2D3 and VDR, and may affect hepatic bile acid homeostasis.

Downregulation of renal type IIa sodium-dependent phosphate cotransporter during lipopolysaccharide-induced acute inflammation.,
American Journal of Physiology, Renal Physiology, Vol.306, No.7, F744-50, 2014.

(要約): The type IIa sodium-dependent phosphate cotransporter (Npt2a) plays a critical role in reabsorption of inorganic phosphate (Pi) by renal proximal tubular cells. Pi abnormalities during early stages of sepsis have been reported, but the mechanisms regulating Pi homeostasis during acute inflammation are poorly understood. We examined the regulation of Pi metabolism and renal Npt2a expression during lipopolysaccharide (LPS)-induced inflammation in mice. Dose-response and time-course studies with LPS showed significant increases of plasma Pi and intact parathyroid hormone (iPTH) levels and renal Pi excretion, while renal calcium excretion was significantly decreased. There was no difference in plasma 1,25-dihydroxyvitamin D levels, but the induction of plasma intact fibroblast growth factor 23 levels peaked 3 h after LPS treatment. Western blotting, immunostaining, and quantitative real-time PCR showed that LPS administration significantly decreased Npt2a protein expression in the brush border membrane (BBM) 3 h after injection, but there was no change in renal Npt2a mRNA levels. Moreover, tumor necrosis factor- injection also increased plasma iPTH and decreased renal BBM Npt2a expression. Importantly, we revealed that parathyroidectomized rats had impaired renal Pi excretion and BBM Npt2a expression in response to LPS. These results suggest that the downregulation of Npt2a expression in renal BBM through induction of plasma iPTH levels alter Pi homeostasis during LPS-induced acute inflammation.

Increasing dietary phosphorus intake from food additives: potential for negative impact on bone health.,
Advances in Nutrition, Vol.5, No.1, 92-97, 2014.

(要約): It is important to consider whether habitual high phosphorus intake adversely affects bone health, because phosphorus intake has been increasing, whereas calcium intake has been decreasing in dietary patterns. A higher total habitual dietary phosphorus intake has been associated with higher serum parathyroid hormone (PTH) and lower serum calcium concentrations in healthy individuals. Higher serum PTH concentrations have been shown in those who consume foods with phosphorus additives. These findings suggest that long-term dietary phosphorus loads and long-term hyperphosphatemia may have important negative effects on bone health. In contrast, PTH concentrations did not increase as a result of high dietary phosphorus intake when phosphorus was provided with adequate amounts of calcium. Intake of foods with a ratio of calcium to phosphorus close to that found in dairy products led to positive effects on bone health. Several randomized controlled trials have shown positive relations between dairy intake and bone mineral density. In our loading test with a low-calcium, high-phosphorus lunch provided to healthy young men, serum PTH concentrations showed peaks at 1 and 6 h, and serum fibroblast growth factor 23 (FGF23) concentrations increased significantly at 8 h after the meal. In contrast, the high-calcium, high-phosphorus meal suppressed the second PTH and FGF23 elevations until 8 h after the meal. This implies that adequate dietary calcium intake is needed to overcome the interfering effects of high phosphorus intake on PTH and FGF23 secretion. FGF23 acts on the parathyroid gland to decrease PTH mRNA and PTH secretion in rats with normal kidney function. However, increased serum FGF23 is an early alteration of mineral metabolism in chronic kidney disease, causing secondary hyperthyroidism, and implying resistance of the parathyroid gland to the action of FGF23 in chronic kidney disease. These findings suggest that long-term high-phosphorus diets may impair bone health mediated by FGF23 resistance both in chronic kidney disease patients and in the healthy population.

What influences appetite more: eating approaches or cooking methods?,
The Journal of Medical Investigation : JMI, Vol.61, No.1.2, 118-125, 2014.

(要約): In general, vegetables are abundantly consumed in a calorie-restricted diet to achieve sufficient satiety through fresh food or various cooking methods. In this study, we examined the effects of different cooking methods on appetite and specific perceptions of the food after consumption; eating approaches were also analyzed by meal duration. A total of 153 individuals aged 20-59 years were assigned to 2 groups: raw vegetable or boiled vegetable meals, including packed meals that were served as test meals with the same energy and vegetable amount. Subjective levels of sensory properties and meal duration were assessed over time using visual analog scales, including questionnaires. Results showed that meal duration was significantly longer for raw vegetable meals than boiled vegetable meals, and there were significantly stronger correlations between meal duration and fullness. A higher degree of fullness was provided by a raw vegetable meal than a boiled vegetable meal, especially in men. However, an excess of raw vegetables led to overall insufficient satisfaction. Taken together, these findings suggest that cooking methods should be altered for different situations with an adequate amount of vegetables, and the meal duration should be recommended to be given as much attention as cooking methods.

Comparison of measured and predicted energy expenditure in patients with liver cirrhosis,
Asia Pacific Journal of Clinical Nutrition, Vol.23, No.2, 197-204, 2014.

(要約): Obesity is a risk factor for the onset of liver cancer in patients with cirrhosis. To prevent overfeeding and obesity, estimation of energy requirement is important, but energy expenditure in patients with liver cirrhosis has not been fully elucidated. This study aimed to investigate resting energy expenditure (REE) and energy intake in patients with cirrhosis and determine adequate energy intake criteria. In this cross-sectional study, indirect calorimetry measurement was conducted in 488 Japanese inpatients with cirrhosis. We compared REE measured by indirect calorimetry (M-REE) with basal energy expenditure (BEE) predicted by the Harris-Benedict equation (H-BEE) and Dietary Reference Intakes (DRI) for Japanese (D-BEE). Mean M-REE (1256 kcal) was significantly lower than H-BEE (1279 kcal); however, it was not significantly different from D-BEE (1254 kcal). Mean M-REE expressed in relation to body weight (BW; REE/kg BW) was 21.7 kcal/kg BW. H-BEE was significantly higher than M-REE in patients in the first and second quartiles of BMI, and D-BEE was significantly different from MREE in patients in the highest and lowest quartiles of BMI. Average energy intake was 30.5 kcal/kg BW, which was 1.4 times greater than REE/kg BW. Although DRI is a useful tool for the estimation of REE in patients in the second and third quartiles of BMI, M-REE is recommended to ensure the provision of adequate nutritional care to patients with cirrhosis, including those in the highest and lowest quartiles of BMI.

Role of nutrient transporters in lifestyle-related diseases,
The Journal of Physical Fitness and Sports Medicine, Vol.2, No.4, 409-416, 2013.

(要約): Nutrient transporters play significant roles in physiological hormonal and cellular functions as well as in the maintenance of nutrient metabolism. Lifestyle-related disease can be defined as caused by a disturbance in nutrient metabolism as found in diabetes, dyslipidemia, arteriosclerosis, etc. Therefore, deterioration of nutrient transporters by a genetic mutation or abnormal regulation would cause various lifestyle-related diseases. For instance, dysregulation of muscular glucose transport causes hyperglycemia, and impairment of pancreatic glucose transport can be related to inadequate insulin secretion. These deleterious changes in glucose transport can be a cause of diabetes mellitus. Here, we introduce some examples that indicate the relationship between impairment of nutrient transporters and development of lifestyle-related diseases.

Induction of the hepatic stearoyl-CoA desaturase 1 gene in offspring after isocaloric administration of high fat sucrose diet during gestation.,
Journal of Clinical Biochemistry and Nutrition, Vol.53, No.3, 150-157, 2013.

(要約): Adverse early nutrition leads to metabolic aberrations in adulthood. Molecular and cellular mechanisms responsible are emerging; specific nutritional causes remain unclarified. We investigated gestational dietary intake and its influences on metabolism in offspring. Three groups of pregnant Sprague-Dawley rats were fed either AIN93G standard diet as control, isocaloric high fat sucrose diet or calorie restriction diet (50% of control) until delivery. All dams were fed control diet ad libitum during lactation. Offsprings' metabolic parameters were assessed at three weeks. Visceral fat and plasma triglycerides of high fat sucrose diet offspring were significantly higher than those of control diet and calorie restriction diet offspring. Plasma leptin level was higher in high fat sucrose diet than control offspring. Conversely, plasma adiponectin was lower in high fat sucrose diet and calorie restriction diet offspring compared to controls. Significant inductions of hepatic mRNA expression of stearoyl-CoA desaturase1 and -5 desaturase genes, were observed in high fat sucrose diet and calorie restriction diet offspring. Gestational high sugar and fat intake even without over energy intake would be more detrimental to metabolisms of offspring compared to calorie restriction.

Dietary phosphate restriction induces hepatic lipid accumulation through dysregulation of cholesterol metabolism in mice.,
Nutrition Research, Vol.33, No.7, 586-593, 2013.

(要約): Excessive inorganic phosphate (Pi) intake and hyperphosphatemia have both been speculated to be risk factors for cardiovascular disease and hypercholesterolemia, and dysregulation of cholesterol metabolism can lead to atherosclerosis. However, the relationship between Pi and cholesterol metabolism has not been investigated in detail. Our recent study showed that triiodothyronine can induce both hyperphosphatemia and hypocholesterolemia in mice. We therefore hypothesized a possible linkage between Pi and cholesterol metabolism. In this study, we investigated the effects of dietary Pi intake on cholesterol metabolism in mice. Mice were divided into 4 groups, which were fed diets containing 1.2% or 0.1% Pi and with or without 2% cholesterol (Pi-sufficient, Pi-restricted, Pi-sufficient + Chol, and Pi-restricted + Chol), for 12 days. Inorganic phosphate-restricted mice exhibited significantly higher liver weights than did Pi-sufficient mice. Interestingly, dietary Pi restriction significantly increased high-cholesterol diet-induced hepatic lipid accumulation. Real-time polymerase chain reaction analysis revealed that dietary Pi restriction decreased expression of hepatic genes involved in cholesterol metabolism and fatty acid biosynthesis. In addition, hepatic messenger RNA levels of several transcription factors including peroxisome proliferator-activated receptors and liver X receptor were markedly decreased by Pi restriction. Furthermore, plasma lipid and lipoprotein profile analysis showed that dietary Pi restriction reduced susceptibility to high-cholesterol diet-induced hyperlipidemia. Importantly, we found that there was a significant negative correlation between plasma levels of Pi and total cholesterol. These results suggest that dietary Pi plays an important role in the development of fatty liver disease and hyperlipidemia induced by a high-cholesterol diet through regulation of lipid metabolism-related gene expression in the liver.

Thyroid hormones decrease plasma 1,25-dihydroxyvitamin D levels through transcriptional repression of the renal 25-hydroxyvitamin D3 1-hydroxylase gene (CYP27B1).,
Endocrinology, Vol.154, No.2, 609-622, 2013.

(要約): The primary determinant of circulating 1,25-dihydroxyvitamin D (1,25[OH](2)D) levels is the activity of 25-hydroxyvitamin D-1-hydroxylase (cytochrome P450 27B1 [CYP27B1]) in the kidney. Hyperthyroid patients have been reported to have low levels of plasma 1,25(OH)(2)D. However, the detailed mechanism of thyroid hormone action on vitamin D metabolism is still poorly understood. The present study determined whether renal CYP27B1 gene expression was negatively regulated by thyroid hormones. T(3)-induced hyperthyroid mice showed marked decreases in plasma 1,25(OH)(2)D levels and in renal expression of CYP27B1 mRNA but no changes in plasma concentrations of calcium, PTH, or fibroblast growth factor-23. In addition, we observed that T(3) administration significantly decreased plasma 1,25(OH)(2)D and renal CYP27B1 mRNA levels that were increased by low-calcium or low-phosphorus diets and induced hypocalcemia in mice fed a low-calcium diet. Promoter analysis revealed that T(3) decreases the basal transcriptional activity of the CYP27B1 gene through thyroid hormone receptors (TR and TR1) and the retinoid X receptor (RXR) in renal proximal tubular cells. Interestingly, we identified an everted repeat negative thyroid hormone response element (1-nTRE) overlapping the sterol regulatory element (1-SRE) and the TATA-box -50 to -20 base pairs from the human CYP27B1 gene transcription start site. Finally, we established that CYP27B1 gene transcription is positively regulated by SRE-binding proteins and that a T(3)-bound TR1/RXR heterodimer inhibits SRE-binding protein-1c-induced transcriptional activity through the 1-nTRE. These results suggest that transcriptional repression of the CYP27B1 gene by T(3)-bound TRs/RXR, acting through the 1-nTRE, results in decreased renal CYP27B1 expression and plasma 1,25(OH)(2)D levels.

Hypercholesterolemia and effects of high cholesterol diet in type IIa sodium-dependent phosphate co-transporter (Npt2a) deficient mice.,
The Journal of Medical Investigation : JMI, Vol.60, No.3-4, 191-196, 2013.

(要約): The type IIa sodium-dependent phosphate co-transporter (Npt2a) is important to maintain renal inorganic phosphate (Pi) homeostasis and the plasma Pi levels. It has reported that disorder of Pi metabolism in kidney can be risk factors for cardiovascular disease as well as hypercholesterolemia. However, the relationship between Pi and cholesterol metabolism has not been clarified. The current study investigated the effects of Npt2a gene ablation that is known as hypophosphatemia model on cholesterol metabolism in mice. Npt2a deficient (Npt2a(-/-)) mice and wild type mice were fed diets with or without 2% cholesterol for 12 days. Plasma lipid and lipoprotein profile analysis revealed that plasma lipid levels (total, LDL and HDL cholesterol) were significantly higher in Npt2a(-/-) mice than wild type (WT) mice. Interestingly, high cholesterol diet markedly increased plasma levels of total, LDL and HDL cholesterol in WT mice, but not Npt2a(-/-) mice. On the other hand, there were no differences in body and liver weight, intake and hepatic lipid accumulation between WT and Npt2a(-/-) mice. These results suggest that ablation of Npt2a gene induces hypercholesterolemia and affects the ability to respond normally to dietary cholesterol.

Treatment of rapid weight loss in a donor with hepatic steatosis in a living donor liver transplantation: a case report,
Hepato-Gastroenterology, Vol.59, No.115, 869-871, 2012.

(要約): The use of steatotic livers for transplantation is often associated with increased primary non-function. To reduce the risk of liver injury, steatosis of the donor liver in living donor liver transplantation (LDLT) was treated with restricted diet and exercise. A 21-year-old male donor, 167cm in height and 87kg in body weight, initially received a 1800kcal/day diet for 9 days which was then gradually reduced using a 1600kcal/day diet for 43 days, followed by a 1500kcal/day diet for one day and was finally maintained on a 1400kcal/day diet for 52 days. Daily exercise consumed 500kcal/day. The non-protein respiratory quotient (npRQ) gradually increased while the non-esterified fatty acids (NEFA) decreased during the course of the 105-day treatment. Consequently, the initial 80% steatosis was reduced to 10% and was accompanied by 13% weight loss for 81 days. The npRQ values and NEFA concentrations in the later period of dietary and exercise treatment were higher and lower, respectively, than in the early treatment period, indicating compensation through long-term treatment. Therefore, energy metabolism and NEFA levels represent important biomarkers for short-term intensive treatment by restricted diet and exercise in donors with hepatic steatosis.

Natto and viscous vegetables in a Japanese style breakfast improved insulin sensitivity, lipid metabolism and oxidative stress in subjects with impaired glucose tolerance,
British Journal of Nutrition, Vol.107, No.8, 1184-1191, 2011.

(要約): We previously suggested that the consumption of natto and viscous vegetables as part of a Japanese-style meal based on white rice (WR) reduced postprandial glucose and insulin levels in healthy subjects. The aim of the present study was to assess whether a single breakfast of natto and viscous vegetables or the same breakfast consumed for 2 weeks could improve glucose control, insulin sensitivity, lipid metabolism and oxidative stress in overweight subjects with impaired glucose tolerance (IGT). A total of eleven free-living subjects with IGT followed a randomised, crossover breakfast intervention for 2 weeks. The test meal included boiled WR with natto (viscous fermented soyabeans), Japanese yam and okra. The control meal included WR with non-viscous boiled soyabeans, potatoes and broccoli. Both meals contained comparable amounts of carbohydrate, fat, protein and fibre. The test meal reduced acute glucose and insulin responses compared to the control meal in the study participants. Insulin sensitivity was assessed using the composite insulin sensitivity index (CISI) after both the test and control meal periods. The test meal resulted in improvements in CISI compared to the baseline, whereas no significant changes were observed after the control meal period. Serum levels of both total and LDL-cholesterol were assessed before and after the test meal period and found to decrease significantly. There was also a tendency towards reduced serum malondialdehyde-modified LDL and N( )-carboxymethyllysine. No differences were observed in the measures of chronic glycaemic control. Thus, we conclude that a breakfast of natto and viscous vegetables consumed for 2 weeks improves insulin sensitivity, serum lipid and oxidative stress.

Liver X receptor negatively regulates fibroblast growth factor 21 in the fatty liver induced by cholesterol-enriched diet.,
The Journal of Nutritional Biochemistry, Vol.23, No.7, 785-790, 2011.

(要約): Cholesterol homeostasis is regulated by the liver X receptor (LXR) at the transcriptional level, but it remains unknown whether LXR can affect expression levels of intrahepatic lipolysis related gene. Recent evidence has demonstrated that fibroblast growth factor 21 (FGF21) regulates hepatic lipolysis and fatty acid utilization. In the present study, we examined the role of LXR in FGF21 gene expression associated with regulation of cross-talk signals between cholesterol and triglyceride metabolism in the liver. An in vivo cholesterol feeding test revealed that intake of excess cholesterol increased cholesterol catabolism related gene expression as well as fatty-acid biosynthesis related gene expression. Moreover, the accumulated cholesterol suppressed FGF21 and hormone-sensitive lipase (HSL) gene expression. After 15-day cholesterol feeding, hepatic triglyceride concentrations were negatively correlated with expression levels of the FGF21 and HSL genes in the liver. An LXR agonist (TO-901317) repressed the FGF21 gene expression in mouse primary hepatocytes and HepG2 cells. A promoter deletion study and electrophoretic mobility shift assay revealed that the human FGF21 promoter has at least one LXR response element located from -37 to -22 bp. In summary, LXR represses FGF21 gene expression at the transcription level and might suppress lipolysis and lipid utilization to protect the liver from excess accumulation of toxic cholesterol.

High phosphate diet reduces atherosclerosis formation in apolipoprotein E-deficient mice.,
Journal of Clinical Biochemistry and Nutrition, Vol.49, No.2, 109-114, 2011.

(要約): Although higher serum phosphate level is a risk factor for cardiovascular diseases in general population as well as chronic kidney disease patients, it has not been clarified whether higher phosphate can affect atherosclerotic plaque formation. In this study, we investigated the effect of prolonged-intake of different concentrations of phosphate on atherosclerosis formation using apolipoprotein E-deficient mice. Apolipoprotein E-deficient mice were fed with high fat diet including 0.6%, 1.2% or 1.8% phosphate. After 20-week treatment, atherosclerotic plaque formation in aorta in 1.8% phosphate diet group was unexpectedly less than that in the other groups. To elucidate mechanisms of suppression of plaque formation by high phosphate diet, we hypothesized that high phosphate diet may modify a profile of monocytes/macrophages suppressing plaque formation. We confirmed that elevated peripheral monocytes (CD11b+, F4/80+ cell numbers) in apolipoprotein E-deficient mice were decreased by feeding with 1.8% P diet. In addition, ex vivo study indicated that high dose of phosphate induced macrophage apoptosis. These observations suggest that excess phosphate intake decreased atherosclerosis formation, at least in part, by changing the profile of peripheral monocytes or inducing apoptosis of macrophages in apolipoprotein E-deficient mice.

Paradoxical regulation of human FGF21 by both fasting and feeding signals: is FGF21 a nutritional adaptation factor?,
PLoS ONE, Vol.6, No.8, e22976, 2011.

(要約): Fibroblast growth factor 21 (FGF21) has recently emerged as a metabolic hormone involved in regulating glucose and lipid metabolism in mouse, but the regulatory mechanisms and actions of FGF21 in humans remain unclear. Here we have investigated the regulatory mechanisms of the human FGF21 gene at the transcriptional level. A deletion study of the human FGF21 promoter (-1672 to +230 bp) revealed two fasting signals, including peroxisome proliferator-activated receptor α (PPARα) and glucagon signals, that independently induced human FGF21 gene transcription in mouse primary hepatocytes. In addition, two feeding signals, glucose and xylitol, also dose-dependently induced human FGF21 gene transcription and mRNA expression in both human HepG2 cells and mouse primary hepatocytes. FGF21 protein expression and secretion were also induced by high glucose stimulation. The human FGF21 promoter (-1672 to +230 bp) was found to have a carbohydrate-responsive element at -380 to -366 bp, which is distinct from the PPAR response element (PPRE). Knock-down of the carbohydrate response element binding protein by RNAi diminished glucose-induced human FGF21 transcription. Moreover, we found that a region from -555 to -443 bp of the human FGF21 promoter region exerts an important role in the activation of basic transcription. In conclusion, human FGF21 gene expression is paradoxically and independently regulated by both fasting and feeding signals. These regulatory mechanisms suggest that human FGF21 is increased with nutritional crisis, including starvation and overfeeding.

Effects of xylitol on metabolic parameters and visceral fat accumulation.,
Journal of Clinical Biochemistry and Nutrition, Vol.49, No.1, 1-7, 2011.

(要約): Xylitol is widely used as a sweetener in foods and medications. Xylitol ingestion causes a small blood glucose rise, and it is commonly used as an alternative to high-energy supplements in diabetics. In previous studies, a xylitol metabolite, xylulose-5-phosphate, was shown to activate carbohydrate response element binding protein, and to promote lipogenic enzyme gene transcription in vitro; however, the effects of xylitol in vivo are not understood. Here we investigated the effects of dietary xylitol on lipid metabolism and visceral fat accumulation in rats fed a high-fat diet. Sprague-Dawley rats were fed a high-fat diet containing 0g (control), 1.0g/100kcal (X1) or 2.0g/100kcal (X2) of xylitol. After the 8-week feeding period, visceral fat mass and plasma insulin and lipid concentrations were significantly lower in xylitol-fed rats than those in high-fat diet rats. Gene expression levels of ChREBP and lipogenic enzymes were higher, whereas the expression of sterol regulatory-element binding protein 1c was lower and fatty acid oxidation-related genes were significantly higher in the liver of xylitol-fed rats as compared with high-fat diet rats. In conclusion, intake of xylitol may be beneficial in preventing the development of obesity and metabolic abnormalities in rats with diet-induced obesity.

Protective effects of dipeptidyl peptidase-4 (DPP-4) inhibitor against increased cell apoptosis induced by dietary sucrose and linoleic acid in mice with diabetes.,
The Journal of Biological Chemistry, Vol.286, No.29, 25467-25476, 2011.

(要約): Chronic exposure to high glucose and fatty acid levels caused by dietary sugar and fat intake induces cell apoptosis, leading to the exacerbation of type 2 diabetes. Oleic acid and linoleic acid are two major dietary fatty acids, but their effects in diabetes are unclear. We challenged cell-specific glucokinase haploinsufficient (Gck(+/-)) mice with a diet containing sucrose and oleic acid (SO) or sucrose and linoleic acid (SL) and analyzed cell apoptosis. In Gck(+/-) but not wild-type mice, SL significantly decreased the cell mass and cell proportion in islet cells arising from increased apoptosis to a greater degree than did SO. The mRNA expression of SREBP-1c was significantly higher, and that of E-cadherin was significantly lower in the islets of Gck(+/-) mice fed SL compared with mice fed SO. We next evaluated monotherapy with desfluorositagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, in these mouse groups. DPP-4 inhibitor protected against cell apoptosis, restored the cell mass, and normalized islet morphology in Gck(+/-) mice fed SL. DPP-4 inhibition normalized the changes in the islet expression of SREBP-1c and E-cadherin mRNA induced by the SL diet. Furthermore, linoleic acid induced cell apoptosis to a greater degree in the presence of high glucose levels than in the presence of low glucose levels in vitro in islets and MIN6 cells, whereas a GLP-1 receptor agonist prevented apoptosis. In conclusion, SL exacerbated cell apoptosis in diabetic Gck(+/-) mice but not in euglycemic wild-type mice, and DPP-4 inhibition protected against these effects.

Analysis of different complexes of type IIa sodium-dependent phosphate transporter in rat renal cortex using blue-native polyacrylamide gel electrophoresis.,
The Journal of Medical Investigation : JMI, Vol.58, No.1-2, 140-147, 2011.

(要約): Type IIa sodium-dependent phosphate transporter (NaPi-IIa) can be localized in the apical plasma membrane of renal proximal tubule to carry out a rate-limiting step of phosphate reabsorption. For the apical localization, NaPi-IIa is required to form a macromolecular complex with some adaptor proteins such as Na(+)/H(+) exchanger regulatory factor 1 (NHERF-1) and ezrin. However, the detail of macromolecular complex containing NaPi-IIa in the apical membrane of the renal proximal tubular cells has not been clarified. In this study, we identified at least four different complexes (220, 480, 920, 1,100 kDa) containing NaPi-IIa by using blue-native polyacrylamide gel electrophoresis. Interestingly, LC-MS/MS analysis and immunoprecipitation analysis reveal that megalin is a component of larger complexes (920 and 1,100 kDa). In addition, NaPi-IIa can be heterogeneously co-localized with ezrin and megalin on the apical membrane of renal proximal tubuler cells by fluorescence microscopy analysis. These results suggest that NaPi-IIa can form some different complexes on the apical plasma membrane of renal proximal tubular cells.

Quercetin Prevents Unloading-Derived Disused Muscle Atrophy by Attenuating the Induction of Ubiquitin Ligases in Tail-Suspension Mice.,
Journal of Natural Products, Vol.73, No.10, 1708-1710, 2010.

(要約): The effects of quercetin (1) were investigated on disused muscle atrophy using mice that underwent tail suspension. Periodic injection of 1 into the gastrocnemius muscle suppressed muscle weight loss and ubiquitin ligase expression. Compound 1 reduced the enhancement of lipid peroxidation in the muscle. Injection of N-acetyl-l-cysteine, but not flavone (2), also prevented muscle weight loss and enhancement of lipid peroxidation. These findings demonstrate that 1 can prevent disused muscle atrophy by attenuating the expression of ubiquitin ligases and that such prevention originates from its antioxidant activity.

Impact of splenectomy in patients with liver cirrhosis: Results from 18 patients in a single center experience.,
Hepatology Research, Vol.40, No.9, 894-900, 2010.

(要約): Aim: With the recent advances in medical or surgical treatments in chronic hepatic disorders, the indications for splenectomy in hepatic disorders have greatly expanded. We performed splenectomy for cirrhotic patients and investigated the effects of splenectomy on hepatic functional reserve and nutrition metabolism. Methods: Eighteen patients (Child-Pugh B/C: 12/6; Child-Pugh A: excluded) who underwent splenectomy at our institute between 2005 and 2008 were enrolled. Twelve patients (67%) had hepatocellular carcinoma (HCC), eight of whom met the Milan criteria. Results: Overall survival rate was 83.3% at 1 year and 62.7% at 2 years. The survival rate of six patients with liver cirrhosis classified a Child-Pugh C was 80.0% at 1 year and 60.0% at 2 years. Three patients underwent hepatic resection and nine patients received ablation therapy against hepatocelluar carcinoma. Portal pressure decreased after splenectomy in most patients (mean decrease, 4.7 mmHg). Four weeks after the operation, the markers of hepatic functional reserve, indocyanine green retention rate at 15 min (ICGR15) and Technetium-99m-galactosyl human serum albumin value ((99m)Tc-GSA), improved from 38.5% to 35.1% and from 0.773 to 0.788 (LHL15), respectively. The non-protein respiratory quotient (npRQ) did not change in short period after the operation. Other outcomes, including liver function test in cirrhotic patients with long-term (1 year) follow-up after splenectomy (n = 7), did not improve significantly. Post-operative complications included portal thrombus (n = 2), ascites (n = 2) were observed in six patients (33%). Conclusion: Splenectomy improved hepatic functional reserve and nutritional metabolism in some cases. However, the long-term outcomes should still be evaluated.

Protective effects of glycoglycerolipids extracted from spinach on 5-fluorouracil induced intestinal mucosal injury.,
The Journal of Medical Investigation : JMI, Vol.57, No.3-4, 314-320, 2010.

(要約): Glycoglycerolipids are mostly found in plants, however the beneficial effects of the glycoglycerolipids on mammalian body have not been understood. In this study, we investigated the effects of glycolipid extracts from spinach, which highly contained glycoglycerolipids, on mucosal injury induced by 5-fluorouracil (5-FU) in rats. Preadministration of glycolipid extracts from spinach (20 mg/kg body weight) prevented villous atrophy, misaligned crypts, and increased inflammatory cytokines in rat jejunum treated with 5-FU (300 mg/kg body weight) compared with the extracts from soybean. The glycolipid extracts from spinach highly contained monogalactosyl-diacylglycerol (MGDG) and diglactosyl-diacylglycerol (DGDG). In Caco-2 cells, MGDG and DGDG inhibited the production of reactive oxygen species induced by phorbol ester. We concluded that glycolipid extracts from spinach has anti-oxidative and anti-inflammatory effects, and the extract may be useful for prevention of drug-induced mucosal injury and other inflammatory diseases.

Consultation clinics for complementary and alternative medicine at Japanese university hospitals: An analysis at Tokushima University Hospital,
Experimental and Therapeutic Medicine, Vol.1, No.3, 481-483, 2010.

(要約): Here, we report on a Consultation Clinic for Complementary and Alternative Medicine (CAM) which we established at Tokushima University Hospital in July of 2007 with the aim of providing person-to-person information on CAM, though not CAM therapy itself. In December of 2008, we received 55 applications for consultation, 37% concerning health foods, 37% Japanese herbal medicine (Kampo), and 26% various other topics. The consultants (nutritionists and pharmacists) communicated individually with 38 applicants; malignancies (26%) and cardiovascular disease (24%) were the main underlying concerns. To promote the quality of consultation, data was collected by means of focus group interviews concerning the perspective of the consultants. Safe and effective use of CAM requires a network of communication linking individuals, consultation teams, physicians, primary care institutions and university hospitals. To advance this goal, we plan to broaden the efforts described herein. Our findings indicate that the specific role of the consultation clinic in promoting the scientific use of CAM merits further study.

Effect of long-term late-evening snack on health-related quality of life in cirrhotic patients.,
Hepatology Research, Vol.40, No.5, 470-476, 2010.

(要約): Aim: In patients with liver cirrhosis, abnormal energy metabolism induces low health-related quality of life (HRQOL) scores. However, late-evening snack (LES) prevents morning starvation in cirrhotic patients. Our aim is to assess the effect of long-term LES on HRQOL in cirrhotic patients, using the 36-item Short Form (SF-36) health survey. Methods: Thirty-nine cirrhotic patients classified as Child-Pugh grade A were recruited. The patients were randomly divided into two groups: 24 were assigned to the non-LES group and 15 to the LES group. SF-36 scores, anthropometric data and serum biochemical parameters were examined in the non-LES and LES groups at 0, 6 and 12 months. Results: Neither anthropometric data nor laboratory data showed significant differences between the non-LES and the LES groups at 0, 6 and 12 months. The role-emotional (RE) HRQOL scores at 6 months and mental health (MH) scores at 6 and 12 months were significantly reduced from the baseline level in the non-LES group. In contrast, these scores remained unchanged in the LES group. General health perception (GH) scores at 12 months, RE at 6 months and MH at 6 and 12 months in the LES group were significantly higher than those of the non-LES group. Conclusion: Long-term LES administration may be helpful in maintaining higher HRQOL in patients with cirrhosis.

Thyroid hormones regulate phosphate homoeostasis through transcriptional control of the renal type IIa sodium-dependent phosphate co-transporter (Npt2a) gene.,
The Biochemical Journal, Vol.427, No.1, 161-169, 2010.

(要約): The type IIa renal sodium-dependent phosphate (Na/Pi) co-transporter Npt2a is implicated in the control of serum phosphate levels. It has been demonstrated previously that renal Npt2a protein and its mRNA expression are both up-regulated by the thyroid hormone T3 (3,3',5-tri-iodothyronine) in rats. However, it has never been established whether the induction was mediated by a direct effect of thyroid hormones on the Npt2a promoter. To address the role of Npt2a in T3-dependent regulation of phosphate homoeostasis and to identify the molecular mechanisms by which thyroid hormones modulate Npt2a gene expression, mice were rendered pharmacologically hypo- and hyper-thyroid. Hypothyroid mice showed low levels of serum phosphate and a marked decrease in renal Npt2a protein abundance. Importantly, we also showed that Npt2a-deficient mice had impaired serum phosphate responsiveness to T3 compared with wild-type mice. Promoter analysis with a luciferase assay revealed that the transcriptional activity of a reporter gene containing the Npt2a promoter and intron 1 was dependent upon TRs (thyroid hormone receptors) and specifically increased by T3 in renal cells. Deletion analysis and EMSAs (electrophoretic mobility-shift assays) determined that there were unique TREs (thyroid-hormone-responsive elements) within intron 1 of the Npt2a gene. These results suggest that Npt2a plays a critical role as a T3-target gene, to control phosphate homoeostasis, and that T3 transcriptionally activates the Npt2a gene via TRs in a renal cell-specific manner.

Increasing early insulin secretion compensate adequately for hepatic insulin resistance in CCl4-induced cirrhosis rats.,
The Journal of Medical Investigation : JMI, Vol.57, No.1-2, 54-61, 2010.

(要約): A number of recent publications have reported an increased frequency prevalence of glucose intolerance with hyperinsulinemia in liver cirrhosis. The aim of this work was to detect, in CCl(4)-induced liver cirrhosis rat, the presence and starting point of muscle and liver insulin resistance. Eighteen rats received intraperitoneal injection of 2 ml of soybean oil containing of CCl(4) twice a week for 20 weeks. We executed standard oral glucose tolerance and clamp study to evaluate systemic insulin resistance. Hepatic glucose uptake was much lower in CCl(4) group than that in control group, but peripheral glucose uptake was not decreased in this study. In contrast, early-phase insulin secretion was enhanced in CCl(4) rat using oral glucose load during clamp methods. These data suggested that increased early insulin secretion compensate adequately for hepatic insulin resistance in rats. However there was a report that peripheral glucose uptake was decreased in the case of human liver cirrhosis, which was formed in the course of time. In a chronic condition, this may be associated with reduced insulin content and developed systemic insulin resistance in liver cirrhosis. Then a long term observation study will be required to examine the presence of muscle insulin resistance in liver cirrhosis.

Hypocaloric high protein diet improves fatty liver and hypertriglyceridemia in sucrose-fed obese rats via two pathways.,
American Journal of Physiology, Endocrinology and Metabolism, Vol.297, No.1, 76-84, 2009.

(要約): The mechanism by which replacement of some dietary carbohydrates with protein during weight loss favors lipid metabolism remains obscure. In this study, we investigated the effect of an energy-restricted, high-protein/low-carbohydrate diet on lipid metabolism in obese rats. High-sucrose-induced obese rats were assigned randomly to one of two energy-restricted dietary interventions: a carbohydrate-based control diet (CD) or a high-protein diet (HPD). Lean rats of the same age were assigned as normal control. There was significantly greater improvement in fatty liver and hypertriglyceridemia with the HPD diet relative to the CD diet. Expression of genes regulated by fibroblast growth factor-21 (FGF21) and involved in liver lipolysis and lipid utilitization, such as lipase and acyl-CoA oxidase, increased in obese rats fed the HPD. Furthermore, there was an inverse correlation between levels of FGF21 gene expression (regulated by glucagon/insulin balance) and increased triglyceride concentrations in liver from obese rats. Expression of hepatic stearoyl-CoA desaturase-1 (SCD1), regulated primarily by the dietary carbohydrate, was also markedly reduced in the HPD group (similar to plasma triglyceride levels in fasting animals) relative to the CD group. In conclusion, a hypocaloric high-protein diet improves fatty liver and hypertriglyceridemia effectively relative to a carbohydrate diet. The two cellular pathways at work behind these benefits include stimulation of hepatic lipolysis and lipid utilization mediated by FGF21 and reduction of hepatic VLDL-TG production by SCD1 regulation.

Dietary Phosphorus Acutely Impairs Endothelial Function.,
Journal of the American Society of Nephrology, Vol.20, No.7, 1504-1512, 2009.

(要約): Excessive dietary phosphorus may increase cardiovascular risk in healthy individuals as well as in patients with chronic kidney disease, but the mechanisms underlying this risk are not completely understood. To determine whether postprandial hyperphosphatemia may promote endothelial dysfunction, we investigated the acute effect of phosphorus loading on endothelial function in vitro and in vivo. Exposing bovine aortic endothelial cells to a phosphorus load increased production of reactive oxygen species, which depended on phosphorus influx via sodium-dependent phosphate transporters, and decreased nitric oxide production via inhibitory phosphorylation of endothelial nitric oxide synthase. Phosphorus loading inhibited endothelium-dependent vasodilation of rat aortic rings. In 11 healthy men, we alternately served meals containing 400 mg or 1200 mg of phosphorus in a double-blind crossover study and measured flow-mediated dilation of the brachial artery before and 2 h after the meals. The high dietary phosphorus load increased serum phosphorus at 2 h and significantly decreased flow-mediated dilation. Flow-mediated dilation correlated inversely with serum phosphorus. Taken together, these findings suggest that endothelial dysfunction mediated by acute postprandial hyperphosphatemia may contribute to the relationship between serum phosphorus level and the risk for cardiovascular morbidity and mortality.

Fermented ginseng improves the first-night effect in humans,
Sleep, Vol.32, No.3, 413-421, 2009.

(要約): The goal of this study was to clarify whether ginseng fermented by lactic acid bacteria (fermented ginseng, FG), can improve the first-night effect (FNE) in humans. Behavioral tests and quantification of mRNA expression related to GABAergic neurotransmission in brain (glutamic acid decarboxylase 1, gamma-aminobutyrate aminotransferase [Abat], gamma-aminobutyric acid transporter 1 [GAT1], gamma-aminobutyric acid transporter 4, gamma-aminobutyric acid A receptor subunit alpha 1 and gamma-aminobutyric acid A receptor subunit alpha 2) were carried out in FG-treated mice. We also performed double-blind sleep recordings of human subjects given FG or placebo. A university-based sleep laboratory. Sixteen healthy male volunteers (aged 20.69 +/- 0.44 years) were observed in the human study. At the end of administration, 2 consecutive all-night polysomnography recordings were performed. Subjects also completed psychological questionnaires, and urine and saliva samples were taken to analyze stress-sensitive markers. The light-dark transition test demonstrated that FG had some anxiolytic effect in mice, but other anxiety measures were unaffected. The hippocampal mRNA expression showed a decrease of Abat and GAT1 suggesting an increase of GABA. Other regions (amygdala and cerebellum) showed no differences. Furthermore, there was some evidence (using simple pairwise comparisons but not supported in the full ANOVA model) that administration of FG tended to diminish decreases in total sleep time and sleep efficiency (seen as first night effects in the placebo group) without affecting sleep architecture. Our results suggest the administration of FG could improve the FNE in humans. The improvement may be related to an anxiolytic effect of FG which acts via GABAergic modification.

Dose-dependent effects of barley cooked with white rice on postprandial glucose and desacyl ghrelin levels.,
Journal of Clinical Biochemistry and Nutrition, Vol.44, No.2, 151-159, 2009.

(要約): White rice is an indispensable staple food in Japan, although it is a high glycemic index food. The objective of this study was to estimate how barley cooked with white rice might affect postprandial glucose, insulin and desacyl ghrelin concentrations as well as fullness. The study was conducted in randomized crossover design with nine healthy subjects. Blood glucose, insulin, free fatty acid and desacyl ghrelin concentrations and subjective levels of fullness and hunger were measured for 240 min after intake of glucose, white rice, 30% rolled barley (30BAR), 50% rolled barley (50BAR) and 100% rolled barley (100BAR) containing 75 g of available carbohydrate. Postprandial glucose and insulin levels were suppressed by intake of 30BAR, 50BAR and 100BAR comparing with those of white rice. Area under the curves of plasma glucose and insulin concentrations was reduced by barley intake in a dose-dependent manner. Although plasma desacyl ghrelin levels decreased postprandially, the degree of reduction was suppressed by barley intake in a dose-dependent manner. Postprandial desacyl ghrelin levels can be a sensitive biomarker of carbohydrate metabolism. The combination of white rice with barley plays a beneficial role in preventing and treating type 2 diabetes, obesity and other metabolic diseases.

Stanniocalcin 2 is positively and negatively controlled by 1,25(OH)(2)D(3) and PTH in renal proximal tubular cells.,
Journal of Molecular Endocrinology, Vol.42, No.3, 261-268, 2009.

(要約): We have previously identified a second mammalian stanniocalcin (STC2) in humans and demonstrated that STC2 inhibits phosphate uptake in an opossum renal proximal tubular cell line (opossum kidney (OK) cells). However, the regulation of Stc2 gene expression in OK cells is not well understood. In this study, we identified the opossum Stc2 cDNA sequence. The opossum STC2 amino acid sequence had 78.8% homology with human STC2, and has a conserved putative N-linked glycosylation site. Next, we investigated the regulation of Stc2 gene expression by the classical calcium and phosphate-regulating factors 1,25(OH)(2)D(3) and PTH in OK cells. In western blot analysis using affinity-purified anti-STC2 antibody, the secretion of STC2 protein was stimulated by 1,25(OH)(2)D(3) in a dose-dependent manner. By contrast, PTH suppressed the induction of STC2 protein secretion by 1,25(OH)(2)D(3). Real-time PCR analysis revealed that Stc2 mRNA expression was increased by 1,25(OH)(2)D(3) in a dose- and time-dependent manner. In addition, actinomycin D, an RNA synthesis inhibitor, prevented the effects of 1,25(OH)(2)D(3) on Stc2 gene expression. On the other hand, PTH and phorbol 12,13-myristic acetate, a specific PKC activator, but not 8-bromo-cyclic AMP, a specific PKA activator, reduced the mRNA levels of Stc2. In addition, Gö6976, a specific PKC inhibitor, abolished the downregulation of Stc2 mRNA expression by PTH. Furthermore, we demonstrated that the renal Stc2 mRNA expression was increased by 1,25(OH)(2)D(3) and decreased by PTH in vivo. These results suggest that STC2 is positively and negatively controlled by 1,25(OH)(2)D(3) and PTH in renal proximal tubular cells.

(要約): Hyperphosphatemia has been known as a risk factor for cardiovascular disease particularly inchronic kidney disease patients. Hyperphosphatemia can be involved in the calcification of vascularsmooth muscle cells, resulting in M¨onkeberg medial calcific sclerosis which is a type of arteriosclerosis.However, it has not been clarified whether hyperphosphatemia can deteriorate endothelialfunction and can be a risk factor of atherosclerosis. Our recent study demonstrated that hyperphosphatemiaincreased oxidative stress and decreased nitric oxide production in endothelial cells.In addition, hyperphosphatemia attenuated endothelium-dependent vasodilation reaction. Theseobservations suggest that hyperphosphatemia may cause endothelial dysfunction, and be an importantfactor for progression of atherosclerosis as well as vascular calcification. Positive associationbetween hyperphosphatemia and cardiovascular disease may be explained by the dual harmfuleffects of phosphorus on the vessels.

Palatinose and oleic acid act together to prevent pancreatic islet disruption in nondiabetic obese Zucker rats.,
The Journal of Medical Investigation : JMI, Vol.55, No.3-4, 183-195, 2008.

(要約): We showed previously that 8-wk consumption of a diet containing palatinose (P, a slowly-absorbed sucrose analogue) and oleic acid (O) ameliorates but a diet containing sucrose (S) and linoleic acid (L) aggravates metabolic abnormalities in Zucker fatty (fa/fa) rats. In this study, we aimed to identify early changes in metabolism in rats induced by certain combinations of carbohydrates and fatty acids. Specifically, male Zucker fatty rats were fed an isocaloric diet containing various combinations of carbohydrates (P; S) and fatty acids (O; L). After 4 wk, no significant differences in body weight, visceral fat mass, plasma parameters (glucose, insulin, lipids, and adipokines), hepatic adiposity and gene expression, and adipose inflammation were observed between dietary groups. In contrast, pancreatic islets of palatinose-fed (PO and PL) rats were smaller and less fibrotic than sucrose-fed (SO and SL) rats. The abnormal alpha-cell distribution and sporadic staining of active caspase-3 common to islets of linoleic-acid-fed rats were not observed in oleic-acid-fed (PO and SO) rats. Accordingly, progressive beta-cell loss was seen in SL rats, but not in PO rats. These findings suggest that pancreatic islets may be initial sites that translate the effects of different combinations of dietary carbohydrates and fats into metabolic changes.

Flavonoids as Substrates and Inhibitors of Myeloperoxidase : Molecular Actions of Aglycone and Metabolites,
Chemical Research in Toxicology, Vol.21, No.8, 1600-1609, 2008.

(要約): Myeloperoxidase (MPO), secreted by activated neutrophils and macrophages at the site of inflammation, may be implicated in the oxidation of protein/lipoprotein during the development of cardiovascular diseases. Flavonoids have been suggested to act as antioxidative and anti-inflammatory agents in vivo; however, their molecular actions have not yet been fully understood. In this study, we examined the molecular basis of the inhibitory effects of dietary flavonoids, such as quercetin, and their metabolites on the catalytic reaction of MPO using a combination of biological assays and theoretical calculation studies. Immunohistochemical staining showed that a quercetin metabolite was colocalized with macrophages, MPO, and dityrosine, an MPO-derived oxidation product of tyrosine, in human atherosclerotic aorta. Quercetin and the plasma metabolites inhibited the formation of dityrosine catalyzed by the MPO enzyme and HL-60 cells in a dose-dependent manner. Spectrometric analysis indicated that quercetin might act as a cosubstrate of MPO resulting in the formation of the oxidized quercetin. Quantitative structure-activity relationship studies showed that the inhibitory actions of flavonoids strongly depended not only on radical scavenging activity but also on hydrophobicity (log P). The requirement of a set of hydroxyl groups at the 3, 5, and 4'-positions and C2-C3 double bond was suggested for the inhibitory effect. The binding of quercetin and the metabolites to a hydrophobic region at the entrance to the distal heme pocket of MPO was also proposed by a computer docking simulation. The current study provides the structure-activity relationships for flavonoids as the anti-inflammatory dietary constituents targeting the MPO-derived oxidative reactions in vivo.

Diurnal amplitudes of arterial pressure and heart rate are dampened in Clock mutant mice and adrenalectomized mice.,
Endocrinology, Vol.149, No.7, 3576-3580, 2008.

(要約): Arterial pressure (AP), heart rate (HR), and cardiovascular diseases, including ischemic heart attack and cerebrovascular accident, show diurnal variation. Evidence that circadian-related genes contribute to cardiovascular control has been accumulated. In this study, we measured the AP and HR of Clock mutant mice on the Jcl/ICR background to determine the role of the Clock gene in cardiovascular function. Mice with mutated Clock genes had a dampened diurnal rhythm of AP and HR, compared with wild-type control mice, and this difference disappeared after adrenalectomy. The diurnal acrophase in both mean arterial pressure and HR was delayed significantly in Clock mutant mice, compared with wild-type mice, and this difference remained after adrenalectomy. Clock mutant mice had a lower concentration of plasma aldosterone, compared with wild-type mice. Our data suggest that the adrenal gland is involved in the diurnal amplitude, but not the acrophase, of AP and HR, and that the function of the Clock gene may be related to the nondipping type of AP elevation.

Effects of lifestyle habits and eating meals together with the family on the prevalence of obesity among school children in Tokushima, Japan: a cross-sectional questionnaire-based survey.,
The Journal of Medical Investigation : JMI, Vol.55, No.1-2, 71-77, 2008.

(要約): Obesity in children has become a major global public health concern. The prevention of obesity must start from early childhood in order to establish sound lifestyle habits and promote healthy adulthood. In this study, we evaluated factors associated with the prevention of obesity and the development of healthy lifestyle habits in children. A cross-sectional, questionnaire-based survey was performed in elementary and junior high school students in Tokushima Prefecture, Japan, during the summer of 2004. The questionnaire consisted of 30 items such as physique, sleep, eating habits, diet, exercise, free time, and attending after-school lessons. Our study revealed that eating meals as a family every day is associated with a lower rate of obesity as well as getting good lifestyle habits such as eating balanced meals and getting enough sleep. Of the 3,291 students who responded to the questionnaire, 2,688 (81.7%) reported that they eat meals with their family every day. The percentage of students who eat meals with their family every day decreased with increasing school grade, with the lowest percent in the junior high school students. However, the results regarding female junior high school students revealed a marked association between eating meals with the family every day and good lifestyle habits. We recommend that parents and school teaching staff encourage the establishment of sound, healthy lifestyle habits in children from early childhood as an effective measure for the prevention of obesity.

Natto and viscous vegetables in a Japanese style meal suppress postprandial glucose and insulin responses,
Asia Pacific Journal of Clinical Nutrition, Vol.17, No.4, 663-668, 2008.

(要約): Naturally viscous vegetables and natto, made by fermenting soybeans, are very palatable and considered to be healthy foods in Japan. The objective was to assess whether the consumption of natto and viscous vegetables as part of a traditional Japanese breakfast based on high-glycemic index white rice affects glycemic, insulinemic, lipidemic and satiety responses in healthy subjects. Eleven healthy subjects consumed the reference, control and test meals in a randomized cross-over design. The test meal, comprising 200 g of boiled white rice with viscous meal (50 g natto, 60 g Japanese yams and 40 g okras), and the control meal, comprising 200 g of white rice with non-viscous boiled soybeans, potatoes and broccoli, contained comparable amounts of carbohydrate, fat, protein and fiber. In addition, whiter rice was used as a reference meal. Blood samples over 180 min were analyzed for glucose, insulin, non-esterified free fatty acid and triacylglyceride. Peak glucose and insulin concentrations after the test meal (6.0 mmol/L and 262 pmol/L) were significantly lower than after the control meal (6.8 mmol/L and 360 pmol/L). The incremental areas under the curve for glucose and insulin over 0-120 min after the test meal were also significantly reduced as compared with the control meal (28 and 27%). The consumption of naturally viscous vegetables with white rice reduced acute glycemia and insulinemia. This practical dietary combination would ensure compliance and favorably alter the risk for diabetes and cardiovascular diseases.

Extracts of Momordica charantia suppress postprandial hyperglycemia in rats.,
Journal of Nutritional Science and Vitaminology, Vol.53, No.6, 482-488, 2007.

(要約): Momordica charantia (bitter melon) is commonly known as vegetable insulin, but the mechanisms underlying its hypoglycemic effect remain unclear. To address this issue, the effects of bitter melon extracts on postprandial glycemic responses have been investigated in rats. An aqueous extract (AE), methanol fraction (MF) and methanol insoluble fraction (MIF) were prepared from bitter melon. An oral sucrose tolerance test revealed that administration of AE, MF or MIF each significantly suppressed plasma glucose levels at 30 min as compared with the control. In addition, the plasma insulin level at 30 min was also significantly lower after MF administration than in the control in the oral sucrose tolerance test. By contrast, these effects of bitter melon extracts were not observed in the oral glucose tolerance test. In terms of mechanism, bitter melon extracts dose-dependently inhibited the sucrase activity of intestinal mucosa with IC(50) values of 8.3, 3.7 and 12.0 mg/mL for AE, MF and MIF, respectively. The fraction with a molecular weight of less than 1,300 (LT 1,300) obtained from MF inhibited the sucrase activity most strongly in an uncompetitive manner with an IC(50) value of 2.6 mg/mL. Taken together, these results demonstrated that bitter melon suppressed postprandial hyperglycemia by inhibition of alpha-glucosidase activity and that the most beneficial component is present in the LT 1,300 fraction obtained from MF.

Advantage of a low glycemic index and low phosphate diet on diabetic nephropathy and aging-related diseases.,
The Journal of Medical Investigation : JMI, Vol.54, No.3-4, 359-365, 2007.

(要約): Diabetic nephropathy is the leading cause of end-stage renal disease (ESRD) in Japan and other Westernized countries. Over 50% of the ESRD patients die from cardiovascular events. Cardiovascular disease (CVD) in ESRD patients with diabetes mellitus (DM) are implicated in the endothelial dysfunction caused by hyperglycemia, hyperlipidemia, and hypertension, and in the vascular calcification of intimal and medial arterial blood vessels caused by hyperphosphatemia. Therefore, dietary control of hyperglycemia and hyperphosphatemia should play an important role in the management of ESRD patients with DM. Furthermore, recent findings suggest that high concentrations of serum phosphate, even if within the normal range, may be a risk factor for CVD and mortality. An in vivo study using klotho knockout mice and fibroblast growth factor 23 (FGF-23) knockout mice has revealed that correction of hyperphosphatemia and hypervitaminosis D could ameliorate the premature aging-like phenotype. A low glycemic index and low phosphate diet may provide an advantage in the prevention of aging-related diseases in healthy individuals as well as in those with chronic kidney disease.

Nutritional treatment of a patient with hepatic cirrhosis with the novel low glycemic index liquid food (Inslow).,
The Journal of Medical Investigation : JMI, Vol.54, No.3-4, 375-380, 2007.

(要約): A sixty-six year-old patient with liver cirrhosis and diabetes was nutritionally treated by administration of the low glycemic index liquid food (Inslow) as a late evening sack (LES) for 6 weeks. The mean energy intake increased from 825+/-48 kcal/d to 1567+/-66 kcal/d after the 6-week treatment period. The fasting glucose level did not change, remaining at about 100 mg/dl throughout this period. Interestingly, the amount of insulin administered was reduced from 38 units before treatment to 28 units in the fifth week of treatment without a change in the fasting glucose level. This indicates a marked improvement in insulin sensitivity due to Inslow administration in this patient. In conclusion, the long-term administration of Inslow as an LES may be an effective treatment for cirrhotic patients.

Dietary palatinose and oleic acid ameliorate disorders of glucose and lipid metabolism in zucker fatty rats.,
The Journal of Nutrition, Vol.137, No.8, 1908-1915, 2007.

(要約): Excessive dietary intake of carbohydrates and fats has been linked to the development of obesity. However, the mechanism by which these dietary factors interact to bring about metabolic changes has not been elucidated. We examined the combined effects of different types of dietary carbohydrates and fats on the etiology of obesity and its complications in the Zucker fatty (fa/fa) rat, a model of obesity. Specifically, these rats were fed an isocaloric diet containing various combinations of carbohydrates [palatinose (P), an insulin-sparing sucrose analogue, and sucrose (S)] and fatty acids [oleic acid (O) and linoleic acid (L)]. After 8 wk, palatinose feeding (PO and PL) led to significant reductions in visceral fat mass, adipocyte cell size, hyperglycemia, and hyperlipidemia compared with sucrose feeding (SO and SL); pancreatic islet hypertrophy was also prevented by palatinose feeding. Linoleic-acid-fed rats (PL and SL) exhibited reduced insulin-immunoreactive staining of the pancreatic islets, enhanced macrophage infiltration in adipose tissue, and an elevated plasma tumor necrosis factor-alpha concentration when compared with oleic-acid-fed rats (PO and SO). Furthermore, sucrose and linoleic acid synergistically increased the expression of genes involved in hepatic gluconeogenesis and lipogenesis [sterol regulatory-element binding protein (SREBP)-1c and SREBP-2]. In conclusion, a diet containing palatinose and oleic acid may prevent diet-induced metabolic abnormalities. The combination of palatinose and oleic acid holds promise for a new approach to preventing and treating obesity and its complications.

Caveolin-1 in extracellular matrix vesicles secreted from osteoblasts.,
Bone, Vol.41, No.1, 52-58, 2007.

(要約): Caveolin-1 is an essential and signature protein of caveolae, which are small invaginations of the plasma membrane enriched in cholesterol and sphingolipids. Although high levels of expression of caveolin-1 have been demonstrated in osteoblasts as well as endothelial cells, fibroblasts, and muscular cells, the role of caveolin-1 in osteoblasts has not been clarified. Here, we show that caveolin-1 is secreted from osteoblasts in the form of matrix vesicles; extracellular vesicles released from the plasma membrane of osteoblasts. In this study, caveolae and matrix vesicles were similarly enriched in cholesterol and sphingomyelin in fractions isolated from mineralizing MC3T3-E1 cells. Interestingly, in the MC3T3-E1 cells caveolin-1 was enriched in the matrix vesicle fraction as well as the caveolar membrane fraction, and the amount of caveolin-1 in the matrix vesicle fraction increased as differentiation progressed. Localization of caveolin-1 in matrix vesicles was also confirmed in murine tibia. Furthermore, overexpression of caveolin-1 enhanced matrix calcification in MC3T3-E1 cells, whereas knockdown of caveolin-1 diminished it. These results suggest that secreted caveolin-1 as a component of matrix vesicles may play an important role in osteoblast calcification.

Early-phase insulin secretion is distributed in obese subjects with glucose intolerance.,
Metabolism: Clinical and Experimental, Vol.56, No.6, 856-862, 2007.

(要約): The loss of early-phase insulin secretion is a characteristic feature of type 2 diabetes mellitus. The aim of this study is to examine when impairment of early-phase insulin secretion occurs and whether it can be related to increase in insulin resistance caused by obesity. We developed an analytical method to qualify the early-phase insulin secretion; that is, we measured C-peptide immunoreactivity (CPR) response to a selective increase in blood glucose level in portal vein during oral glucose load under a euglycemic hyperinsulinemic clamp (clamp-OGL). Glucose infusion rate, hepatic glucose uptake, and CPR response during clamp-OGL were measured in 30 subjects with diabetes who were divided into 3 groups based on body mass index, 13 obese subjects with normal glucose tolerance (O-NGT), 10 obese subjects with impaired glucose tolerance (O-IGT), and 15 healthy subjects. Significant increase in CPR levels at 10 minutes in clamp-OGL compared with those at steady state was observed in healthy subjects and in O-NGT; however, those were small or absent in diabetic patients and in O-IGT. The incremental ratio of CPR was not correlated to the makers of insulin resistance. The early-phase insulin secretion is well maintained in O-NGT; however, early-phase insulin secretion has already been disturbed in obese subjects with glucose intolerance.

Mechanism of rapid-phase insulin response to elevation of portal glucose concentration.,
American Journal of Physiology, Endocrinology and Metabolism, Vol.293, No.2, E515-22, 2007.

(要約): The hepatoportal region is important for glucose sensing; however, the relationship between the hepatoportal glucose-sensing system and the postprandial rapid phase of the insulin response has been unclear. We examined whether a rapid-phase insulin response to low amounts of intraportal glucose infusion would occur, compared that with the response to intrajugular glucose infusion in conscious rats, and assessed whether this sensing system was associated with autonomic nerve activity. The increases in plasma glucose concentration did not differ between the two infusions at 3 min, but the rapid-phase insulin response was detected only in the intraportal infusion. A sharp and rapid insulin response was observed at 3 min after intraportal infusion of a small amount of glucose but not after intrajugular infusion. Furthermore, this insulin response was also induced by intraportal fructose infusion but not by nonmetabolizable sugars. The rapid-phase insulin response at 3 min during intraportal infusion did not differ between rats that had undergone hepatic vagotomy or chemical sympathectomy with 6-hydroxydopamine compared with control rats, but this response disappeared in rats that had undergone chemical vagotomy with atropine. We conclude that the elevation of glucose concentration in the hepatoportal region induced afferent signals from undetectable sensors and that these signals stimulate pancreas to induce the rapid-phase insulin response via cholinergic nerve action.

Effects of prolonged high phosphorus diet on phosphorus and calcium balance in rats.,
Journal of Clinical Biochemistry and Nutrition, Vol.40, No.3, 221-228, 2007.

(要約): The amount of phosphorus contained in food as food additives is currently increasing and a high intake of phosphorus can cause various diseases. To determine the effects of a prolonged high phosphorus diet, here we investigated the phosphorus and calcium balance and expression of type IIa sodium-dependent phosphate transporter (Npt IIa) in mature rats. Wistar male rats (8-weeks old) were divided into five groups and fed diets containing 0.6% calcium plus 0.3, 0.6, 0.9, 1.2 or 1.5% phosphorus for 4 weeks. Urinary and fecal phosphorus excretions were significantly increased by the high phosphorus diets (from 0.6 to 1.5%), dependent on the amount of dietary phosphorus. The net absorption of intestinal phosphorus was also significantly increased by high phosphorus diets. As a result, a negative phosphorus balance was observed in rats given the 1.2% or 1.5% phosphorus diets. Serum parathyroid hormone and 1,25-dihydroxyvitamin D(3) concentrations were increased by high phosphorus diets. In addition, high phosphorus diets decreased the expression of Npt IIa mRNA and protein in the renal brush border membrane. Taken together, these results suggest that diets containing 1.2 or 1.5% phosphorus plus 0.6% calcium have potentially adverse effects on phosphorus homeostasis in mature rat.

The anti-obesity effect of the palatinose-based formula Inslow is likely due to an increase in the hepatic PPAR-α and adipocyte PPAR-γ gene expressions.,
Journal of Clinical Biochemistry and Nutrition, Vol.40, No.3, 234-241, 2007.

(要約): Abdominal obesity is a principal risk factor in the development of metabolic syndrome. Previously, we showed that a palatinose-based liquid formula, Inslow/MHN-01, suppressed postprandial plasma glucose level and reduced visceral fat accumulation better than the standard formula (SF). To elucidate the mechanism of Inslow-mediated anti-obesity effect, expression levels of genes involved in the glucose and lipid metabolism were compared in Inslow- and SF-fed rats. Both fasting plasma insulin level and average islet sizes were reduced in the Inslow group. We also found less abdominal fat accumulation and reduced hepatic triacylglycerol content in the Inslow group. Expression of the beta-oxidation enzymes and uncoupling potein-2 (UCP-2) mRNAs in the liver of the Inslow group were higher than the SF group, which was due to a concomitant higher expression of the peroxisome proliferator-activated receptor (PPAR)-alpha mRNA in the former. Furthermore, expression of the UCP-2 and adiponectin mRNAs in the epididymal fat were higher in the Inslow group than the SF group, and were stimulated by a concomitant increase of the PPAR-gamma gene expression in the former. These results strongly suggested that the anti-obesity effect of Inslow was due to an increase in the hepatic PPAR-alpha and adipocyte PPAR-gamma gene expressions.

Effects of a palatinose-based liquid diet (Inslow) on glycemic control and the second-meal effect in healthy men.,
Metabolism: Clinical and Experimental, Vol.56, No.1, 115-121, 2007.

(要約): Postprandial hyperglycemia induces prolonged hyperinsulinemia, which is a risk factor for type 2 diabetes mellitus. Foods with a low glycemic index blunt the rapid rise in postprandial plasma glucose and insulin levels. We herein investigated the effects of a novel, palatinose-based liquid diet (Inslow, Meiji Dairy Products, Tokyo, Japan) on postprandial plasma glucose and insulin levels and on the rate of substrate oxidation in 7 healthy men. Furthermore, to examine the effects of Inslow on the second-meal effect, we quantified our subjects' postprandial plasma glucose, insulin, and free fatty acid levels for up to 7 hours after they ingested a breakfast containing Inslow or control formula, followed by a standard lunch 5 hours later. Our results showed that peak plasma glucose and insulin levels 30 minutes after Inslow loading were lower than after control formula loading. Postprandial fat oxidation rates in the Inslow group were higher than in the control formula group (P < .05). In the second-meal effect study, plasma glucose and insulin levels after lunch in the Inslow group were lower than in the control formula group (P < .01), although the peak levels in these groups were not different. The free fatty acid concentration in the Inslow group immediately before lunch was significantly lower than in the control formula group (P < .05). In conclusion, consumption of Inslow at breakfast appears to improve patient glycemic control by reducing their postprandial plasma glucose and insulin levels after lunch (second-meal effect).

Water extract of Cordyceps sinensis (WECS) inhibits the RANKL-induced osteoclast differentiation.,
BioFactors, Vol.30, No.2, 105-116, 2007.

(要約): It has been reported that Cordyceps sinensis, a traditional Chinese medicine, has various pharmacological effects. The aim of this study was to clarify the effect of water extract of Cordyceps sinensis (WECS) on osteoclast differentiation in vitro. In mouse bone marrow cells and monocyte/macrophage cell line RAW264.7, WECS dose-dependently inhibited the receptor activator of nuclear factor kappa B (NF-kappaB) ligand (RANKL)-induced osteoclast differentiation by tartrate-resistant acid phosphatase (TRAP) staining. In fact, cytotoxic effect was not observed in the RAW264.7 cells treated with WECS. Moreover, the mRNA expression of osteoclast related genes (calcitonin receptor, cathepsin K, matrix metalloprotease 9 and nuclear factor of activated T cells c1) was also inhibited by WECS. Investigation of inhibitory mechanism by using electrophoretic mobility shift assay (EMSA) and Western blot analysis revealed that WECS inhibited the activation of NF-kappaB through the prevention of IkappaBalpha phosphorylation. In conclusion, the present results demonstrate for the first time that WECS is a potent inhibitor of the RANKL-induced osteoclast differentiation through a mechanism involving the NF-kappaB pathway.

Acute effect of oral phosphate loading on serum fibroblast growth factor 23 levels in healthy men.,
Kidney International, Vol.70, No.12, 2141-2147, 2006.

(要約): Serum fibroblast growth factor 23 (FGF23) is a novel phosphaturic factor and important for the regulation of inorganic phosphate (Pi) homeostasis. In this study, we examined an acute effect of oral Pi loading on serum FGF23 levels to clarify the role in rapid adjustment of serum Pi level. We performed a randomized, double-blind, crossover study in eight healthy male volunteers. The subjects were alternately served one of three test meals containing different Pi amounts (400 mg (P400), 800 mg (P800), and 1200 mg (P1200)) as lunch at noon. The postprandial changes in serum levels of Pi, Ca, 1,25-dihydroxyvitamin D, intact-parathyroid hormone (iPTH), intact-FGF23 (iFGF23), and urinary excretion of Pi and Ca until 8 h after Pi loading were estimated. Serum Pi levels and urinary Pi excretion significantly increased within 1 h after P400 and P800 intake. Serum iPTH levels at 1-2 and 4-6 h after P1200 intake was significantly higher than those of P400 intake. Serum iFGF23 levels slightly decreased up to 8 h after P400 intake and up to 6 h after P800 intake, but not changed in P1200 intake. Significant increase of iFGF23 was observed at 8 h after P1200 intake compared with both P400 and P800 intake. Additionally, negative association was detected between iFGF23 and serum Pi, whereas positive association was observed between iPTH and serum Pi during the short period. We conclude that oral Pi loading cannot rapidly increase serum FGF23 level. FGF23 may be not associated with rapid adaptation of Pi homeostasis.

Restraint stress alters the duodenal expression of genes important for lipid metabolism in rat.,
Toxicology, Vol.227, No.3, 248-261, 2006.

(要約): Stress, such as trauma and injury, is known to cause transcriptional changes in various tissues; however, there is little information on tissue-specific gene expression in response to stress. Here, we have examined duodenal gene expression in rats subjected to whole-body immobilization in order to elucidate the mechanism underlying the stress response in the duodenum--one of the tissues that is most sensitive to external stress. DNA microarray analysis revealed that the immobilization for 2 weeks caused great changes in gene expression in the rat duodenum: 165 genes exhibited more than a two-fold change in expression level (103 up-regulated; 62 down-regulated). In addition, functional classification of these genes showed that immobilization preferentially stimulated the expression of genes related to lipid metabolism, including genes encoding mitochondrial HMG-CoA synthase, a key enzyme in ketogenesis; solute carrier 27A2, a fatty acid transporter; and dienoyl CoA reductase, a key enzyme in beta-oxidation. To elucidate the factors mediating these immobilization-induced changes, we treated rats and small intestinal IEC-6 cells with dexamethasone and hydrogen peroxide. In both rats and IEC-6 cells, treatment with dexamethasone induced changes in gene expression that mimicked the immobilization-mediated increase in expression of the mitochondrial HMG-CoA synthase and dienoyl CoA reductase transcripts, suggesting that stress-induced synthesis of glucocorticoid hormones mediates, at least in part, the stress response in the duodenum. These results suggest that immobilization may alter lipid metabolism in the small intestine by modifying the expression of specific genes through which the small intestine may seek to protect itself from stress-induced damage.

Effect of late evening snack with rice ball on energy metabolism in liver cirrhosis.,
European Journal of Clinical Nutrition, Vol.60, No.9, 1067-1072, 2006.

(要約): This study investigates the effects of a late evening snack (LES), of 200 kcal of rice ball, on energy metabolism in cirrhotic patients. Impaired nutritional metabolism has been associated with cirrhosis, and frequent intake of small meals may prevent early-onset starvation, and maintain nourishment in these patients. Twenty-one cirrhotic patients and 26 control subjects (Control) were recruited for this study. Patients were subsequently treated by LES (LC-LES) and by a non-LES regimen (LC-NLES). Resting energy expenditure and respiratory quotient (RQ) were assessed by indirect calorimetry at 0830, 1130 and 1430. Blood glucose and non-esterified fatty acids (NEFA) were measured just before the energy metabolism measurements. The regular diet included three major meals and LES, at 0900, 1200, 1800 and 2100, respectively. The Control and LC-NLES groups received only the major meals, whereas the LC-LES group received three meals plus 200 kcal LES for 7 days. There was no difference in the total energy intake among Control, LC-NLES and LC-LES groups. Respiratory quotient in LC-NLES was significantly lower than that of Control at 0830. Respiratory quotient value in LC-LES significantly elevated from that in LC-NLES. The RQ values did not differ among Control, LC-NLES and LC-LES at 2 h after the meal (1130 and 1430). Non-esterified fatty acids in LC-LES were lower than that in LC-NLES after overnight fasting. The ingestion of a 200 kcal rice ball LES can improve the nutritional metabolism in cirrhotic patients.

Immobilization decreases duodenal calcium absorption through a 1,25-dihydroxyvitamin D-dependent pathway.,
Journal of Bone and Mineral Metabolism, Vol.24, No.4, 291-299, 2006.

(要約): Immobilization induces significant and progressive bone loss, with an increase in urinary excretion and a decrease in intestinal absorption of calcium. These actions lead to negative calcium balance and the development of disuse osteoporosis. The aims of this study were to evaluate the molecular mechanisms of decreased intestinal calcium absorption and to determine the effect of dietary 1,25-dihydroxyvitamin D [1,25(OH)2D] and a high-calcium diet on bone loss due to immobilization. The immobilized rat model was developed in the Bollman cage III to induce systemic disuse osteoporosis in the animals. There was a significant decrease in lumbar bone mineral density (BMD) and intestinal calcium absorption in the immobilized group compared with the controls. Serum 25-hydroxyvitamin D concentration did not change, but 1,25(OH)2D concentration decreased significantly. The mRNA levels of renal 25-hydoxyvitamin D 24-hydroxylase (24OHase) increased, whereas those of renal 25-hydroxyvitamin D 1-alpha hydroxylase (1alpha-hydroxylase), duodenal transient receptor potential cation channel, subfamily V, member 6 (TRPV6), TRPV5, and calbindin-D9k were all decreased. A high-calcium diet did not prevent the reduction in lumbar BMD or affect the mRNA expression of proteins related to calcium transport. Dietary administration of 1,25(OH)2D increased the intestinal calcium absorption that had been downregulated by immobilization. TRPV6, TRPV5, and calbindin-D9k mRNA levels were also upregulated, resulting in prevention of the reduction in lumbar BMD. Therefore, it is concluded that dietary 1,25(OH)2D prevented decreases in intestinal calcium absorption and simultaneously prevented bone loss in immobilized rats. However, it remains unclear that calcium absorption and expression of calcium transport proteins are essential for the regulation of lumbar BMD.

Alternative promoters and renal cell-specific regulation of the mouse type IIa sodium-dependent phosphate cotransporter gene,
Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression, Vol.1732, No.1-3, 43-52, 2005.

(要約): The type IIa sodium-dependent phosphate cotransporter (NPT2a) expressed in renal proximal tubules represents an important determinant in maintaining inorganic phosphate (Pi) homeostasis. In the present study, we identified two variant transcripts of the mouse NPT2a gene, Npt2a-v1 and Npt2a-v2, characterized by the presence of alternative first exons (either exon 1A or exon 1B). The chromosomal structure analysis revealed that the Npt2a gene comprises of two promoters (promoters 1 and 2) and 14 exons, and spans approximately 17 kb. Quantitative PCR analysis showed that renal mRNA levels of both the variants markedly decreased in X-linked vitamin D-resistant hypophosphatemic rickets (Hyp) mice compared to normal littermates. Interestingly, transcriptional activity of a reporter gene, containing Npt2a promoters 1 and 2, was renal cell-specifically increased by 1alpha, 25(OH)2D3 and its analogs. The deletion analysis revealed that the CAAT box in the Npt2a promoter 2 is important for the 1alpha, 25(OH)2D3-dependent renal cell-specific activation of the reporter gene. These data suggested that two alternative promoters control the renal expression of Npt2a gene and both Npt2a variant transcripts are down regulated in Hyp mice.

Role of membrane microdomains in PTH-mediated down-regulation of NaPi-IIa in opossum kidney cells,
Kidney International, Vol.68, No.3, 1137-1147, 2005.

(要約): Parathyroid hormone (PTH) rapidly down-regulates type IIa sodium-dependent phosphate transporter (NaPi-IIa) via an endocytic pathway. Since the relationship between PTH signaling and NaPi-IIa endocytosis has not been explored, we investigated the role of membrane microdomains in this process. We examined the submembrane localization of NaPi-IIa in opossum kidney (OK-N2) cells that stably expressed human NaPi-IIa, and searched for a PTH-induced specific phosphorylating substrate on their membrane microdomains by immunoblotting with specific antibody against phospho substrates of protein kinases. We found that NaPi-IIa was primarily localized in low-density membrane (LDM) domains of the plasma membrane; PTH reduced the levels of immunoreactive NaPi-IIa in these domains. Furthermore, PTH activated both protein kinase A (PKA) and protein kinase Calpha (PKCa) and increased the phosphorylation of 250 kD and 80 kD substrates; this latter substrate was identified as ezrin, which a member of the ezrin-radixin-moesin (ERM) protein family. In response to PTH, ezrin was phosphorylated by both PKA and PKC. Dominant negative ezrin blocked the reduction in NaPi-IIa expression in the LDM domains that was induced by PTH. These data suggest that NaPi-IIa and PTH-induced phosphorylated proteins that include ezrin are compartmentalized in LDM microdomains. This compartmentalization may play an important role in the down-regulation of NaPi-IIa via endocytosis.

Stress control and human nutrition,
The Journal of Medical Investigation : JMI, Vol.51, No.3-4, 139-145, 2004.

(要約): Stress is a pervasive factor in everyday life that critically affects development and functioning. Severe and prolonged stress exposure impairs homeostatic mechanisms, particularly associated with the onset of depressive illness. Brain food is aimed at preventing as well as treating a growing number of stress-related mental disorders. Some topics on the association of stress and nutrition is reviewed. (1) An increased activity of serotonergic neurons in the brain is an established consequence of stress. An increase in brain tryptophan levels on the order of that produced by eating a carbohydrate-rich/protein-poor meal causes parallel increases in the amounts of serotonin released into synapses. (2) Eating is thought to be suppressed during stress, due to anorectic effects of corticotrophin releasing hormone, and increased during recovery from stress, due to appetite stimulating effects of residual cortisol. (3) A strong inverse association between coffee intake and risk of suicide. (4) Night eating syndrome has been found to occur during periods of stress and is associated with poor results at attempts to lose weight and disturbances in the hypothalamic-pituitary-adrenal axis. (5) Dietary antioxidants present in fruits and vegetables may improve cognitive function. Therefore, it is concluded that the establishment of functional foods that correctly regulate stress response must be firmly based upon scientific knowledge and legal regulation.

Effect of a novel palatinose-based liquid balanced formula (MHN-01) on glucose and lipid metabolism in male Sprague-Dawley rats after short- and long-term ingestion.,
Metabolism: Clinical and Experimental, Vol.53, No.8, 977-983, 2004.

(要約): Postprandial hyperglycemia and hyperinsulinemia are often present in obese subjects with glucose intolerance in whom insufficient early phase insulin secretion and subsequent delayed hyperinsulin response are observed. To address this problem, a novel palatinose-based enteral formula designated as MHN-01 was developed for the prevention of postprandial hyperglycemia and hyperinsulinemia. The effects of MHN-01 on carbohydrate and lipid metabolism in Sprague-Dawley (SD) rats were compared with those of the standard balanced formula (SBF). After a bolus intragastric injection of each formula equivalent to 0.9 g/kg carbohydrate, the peak levels of plasma glucose (PG) and insulin (IRI) in peripheral and portal veins of the MHN-01 group were significantly lower than those of the SBF group. The areas under the curve of PG and IRI in the MHN-01 group were 58.0% and 43.1% of those in the SBF group in the femoral vein and 65.0% and 69.3% in the portal vein, respectively. In the 2-month study, serum levels of IRI and triglyceride in peripheral blood in the MHN-01 group decreased and those in the SBF group increased compared with initial levels. Consequently, both levels in the MHN-01 group were significantly lower than those in the SBF group. In addition, the amount of accumulated fat in abdominal adipose tissue and liver tissue of the MHN-01 group was markedly reduced in comparison to that of the SBF group. Insulin sensitivity, evaluated as glucose infusion rate using the hyperinsulinemic euglycemic clamp technique, in the MHN-01 group was higher than that in the SBF group. Thus, in comparison to SBF, MHN-01 suppressed postprandial hyperglycemia and hyperinsulinemia, reduced visceral fat accumulation, and improved insulin sensitivity. Therefore, human study on the effects of MHN-01 on carbohydrate and lipid metabolism will be recommended to confirm whether MHN-01 may be a useful functional food for the treatment and prevention of insulin resistance.

Inorganic phosphate homeostasis and the role of dietary phosphorus.,
Journal of Cellular and Molecular Medicine, Vol.8, No.2, 191-200, 2004.

(要約): Inorganic phosphate (Pi) is required for cellular function and skeletal mineralization. Serum Pi level is maintained within a narrow range through a complex interplay between intestinal absorption, exchange with intracellular and bone storage pools, and renal tubular reabsorption. The crucial regulated step in Pi homeostasis is the transport of Pi across the renal proximal tubule. Type II sodium-dependent phosphate (Na/Pi) cotransporter (NPT2) is the major molecule in the renal proximal tubule and is regulated by Pi, parathyroid hormone and by 1,25-dihydroxyvitamin D. Recent studies of inherited and acquired hypophosphatemia [X-linked hypophosphatemic rickets/osteomalacia (XLH), autosomal dominant hypophosphatemic rickets/osteomalacia (ADHR) and tumor-induced rickets/osteomalacia (TIO)], which exhibit similar biochemical and clinical features, have led to the identification of novel genes, PHEX and FGF23, that play a role in the regulation of Pi homeostasis. The PHEX gene, which is mutated in XLH, encodes an endopeptidase, predominantly expressed in bone and teeth, but not in kidney. FGF-23 may be a substrate of this endopeptidase and may therefore accumulate in patients with XLH. In the case of ADHR mutations in the furin cleavage site, which prevent the processing of FGF-23 into fragments, lead to the accumulation of a "stable" circulating form of the peptide which also inhibits renal Pi reabsorption. In the case of TIO, ectopic overproduction of FGF-23 overwhelms its processing and degradation by PHEX, leading to the accumulation of FGF-23 in the circulation and inhibition of renal Pi reabsorption. Mice homozygous for severely hypomorphic alleles of the Klotho gene exhibit a syndrome resembling human aging, including atherosclerosis, osteoporosis, emphysema, and infertility. The KLOTHO locus is associated with human survival, defined as postnatal life expectancy, and longevity, defined as life expectancy after 75. In considering the relationship of klotho expression to the dietary Pi level, the klotho protein seemed to be negatively controlled by dietary Pi.

Combination Treatment with 1α,25-Dihydroxyvitamin D₃ and 9-cis-Retinoic Acid Directly Inhibits Human Telomerase Reverse Transcriptase Transcription in Prostate Cancer Cells,
Molecular Cancer Therapeutics, Vol.2, No.8, 739-746, 2003.

(要約): The vitamin D(3) receptor, which is the nuclear receptor for 1alpha,25-dihydroxyvitamin D(3) (VD(3)), forms a heterodimer with the retinoid X receptor (RXR), which is the nuclear receptor for 9-cis-retinoic acid (9-cis-RA). The heterodimer binds to a specific response element consisting of two directly repeated pairs of motifs, AGGTGA, spaced by three nucleotides [direct repeat (DR) 3] and modulates the expression of VD(3)-responsive genes. Telomerase activity, which is seen in most immortal cells and germ cells, is a complex of enzymes that maintain the length of telomeres. One of the major components of human telomerase, human telomerase reverse transcriptase (hTERT), is the catalytic subunit, and the expression of hTERT might correlate most strongly with telomerase activity. We found that the sequence of 5'-AGTTCATGGAGTTCA-3' (DR3') is similar to that of DR3 in the promoter region of hTERT. Our results showed that the combination of VD(3) and 9-cis-RA inhibited telomerase activity through direct interaction of the heterodimer of vitamin D(3) receptor and RXR with the DR3' sequence in the hTERT promoter as well as the combination of VD(3) and selective RXR ligand did. Also, in vivo data showed that the growth of xenografts in nude mice was inhibited by VD(3) and 9-cis-RA. The results of the present study provide evidence on the molecular mechanism of the inhibition of cell growth by these agents, and they could be novel therapeutic agents for prostate cancer.

Higher Concentrations of Interferon-γ Enhances Uptake and Transport of Dietary Antigens by Human Intestinal Cells: A Study Using Cultured Caco-2 Cells,
Journal of Nutritional Science and Vitaminology, Vol.49, No.3, 179-186, 2003.

(要約): Besides functioning as a mucosal barrier and transporting nutrients, intestinal epithelial cells (IECs) also serve as antigen-presenting cells (APCs). Modification of protein antigens by proteolysis is one of the principal steps in antigen presentation to Th cells. We used a Caco-2 intestinal epithelial cell line to investigate the transepithelial transport of the dietary antigen, ovalbumin (OVA). We also examined the effects of the proinflammatory cytokine interferon-gamma (IFN-gamma) on the antigen transport process in Caco-2 cell layers. Caco-2 cell layers transferred both intact and degraded OVA from the mucosal to the serosal side. IFN-gamma stimulated OVA transport and most of the transported OVA in such cells were degraded. We also examined OVA uptake by Caco-2 cells using immunohistochemical means. Caco-2 cells incorporated OVA in a time-dependent manner and IFN-gamma significantly enhanced antigen internalization. Flow cytometry also demonstrated that IFN-gamma elevated the internalization of FITC-OVA. We also determined the effects of low and high concentrations of IFN-gamma on mucosal permeability and internalization of FITC-OVA. Although both 10 and 50 ng/mL IFN-gamma stimulated mucosal permeability to the same extent, more FITC-OVA was internalized by Caco-2 cells incubated with 50 than with 10 ng/mL IFN-gamma. These results suggest that the effects of IFN-gamma on mucosal permeability and the internalization of antigens by intestinal epithelial cells are brought about by different mechanisms.

Increase in IP3 and intracellular Ca²⁺ induced by phosphate depletion in LLC-PK₁ cells.,
Biochemical and Biophysical Research Communications, Vol.305, No.2, 287-291, 2003.

(要約): The mechanisms by which Pi depletion rapidly regulates gene expression and cellular function have not been clarified. Here, we found a rapid increase in intracellular ionized calcium [Ca(2+)](i) by phosphate depletion in LLC-PK(1) cells using confocal microscopy with the green-fluorescence protein based calcium indicator "yellow cameleon 2.1." The increase of [Ca(2+)](i) was observed in the presence or absence of extracellular Ca(2+). At the same time, an approximately twofold increase in intracellular inositol 1,4,5-triphosphate (IP(3)) occurred in response to the acute Pi depletion in the medium. Furthermore, 2-aminoethoxydiphenyl borate completely blocked the [Ca(2+)](i) increase induced by Pi depletion. These results suggest that Pi depletion causes IP(3)-mediated release of Ca(2+) from intracellular Ca(2+) pools and rapidly increases [Ca(2+)](i) in LLC-PK(1) cells.

Phosphorus supply per capita from food in Japan between 1960 and 1995,
Journal of Nutritional Science and Vitaminology, Vol.48, No.2, 102-108, 2002.

(要約): The awareness of phosphorus intake is important because hyperphosphatemia and hypophosphatemia both impair bone metabolism. Phosphorus consumption from food was obtained from values in the Food Balance Sheet (PBS) of Japan from 1960 to 1995. The amounts of phosphorus calculated from the FBS increased gradually from 1,243 mg/d in 1960 to 1,332 mg/d in 1975 and to 1,421 mg/d in 1995. This is explained by the increased consumption of cow's milk and milk products, meat, and chicken eggs. The main foods supplying phosphorus in 1995 were cereals, milk and milk products, fishes and shellfishes, and vegetables; their contributions were 24.4, 15.8, 14.2, and 10.9%, respectively. The phosphorus-to-calcium ratio calculated from the FBS was 3.51 in 1960, which decreased to 2.89 in 1975 and 2.44 in 1995. Therefore total phosphorus consumption in 1995 was presumably more than 1,500 mg/d when imported food containing phosphorus and the consumption of phosphorus-containing food additives in Japan are also considered. These findings suggest that the phosphorus consumption estimated from the FBS is increasing and that more attention should be paid to the maintenance of healthy bones in Japan, where the average amount of calcium intake is less than 600 mg/d.

Hydrogen Peroxide Stimulates c-Src-mediated Big Mitogen-activated Protein Kinase 1(BMK1) and the MEF2C Signaling Pathway in PC12 Cells,
The Journal of Biological Chemistry, Vol.277, No.11, 9614-9621, 2002.

(要約): Reactive oxygen species, generated by reduction-oxidation (redox) reactions, have been recognized as one of the major mediators of ischemia and reperfusion injury in the brain. Reactive oxygen species-induced cerebral events are attributable, in part, to the change in intracellular signaling molecules including mitogen-activated protein (MAP) kinases. Big MAP kinase 1 (BMK1), also known as ERK5, is a newly identified member of the MAP kinase family and has been reported to be sensitive to oxidative stress. In the present study, we examined the effect of H(2)O(2) on BMK1 activity in PC12 cells, and we investigated the pathophysiological implication of BMK1. Findings showed that BMK1 was rapidly and significantly activated by H(2)O(2) in a concentration-dependent manner in PC12 cells. BMK1 activation by H(2)O(2) was inhibited by both PD98059 and U0126, which were reported to inhibit MEK5 as well as MEK1/2. c-Src was suggested to be involved in BMK1 activation from the experiments with herbimycin A and PP2, specific inhibitors of Src family kinases. Transfection of kinase-inactive Src also inhibited H(2)O(2)-induced BMK1 activation. In addition, H(2)O(2) treatment of cells induced an enhancement of DNA binding activity of MEF2C, a downstream transcription factor of BMK1 in PC12 cells. Finally, pretreatment of cells with PD98059 and U0126 resulted in an increase in cell death including apoptosis by H(2)O(2) in ERK1/2 down-regulated cells as well as in intact PC12 cells. These findings suggest that c-Src mediated BMK1 activation by H(2)O(2) may counteract ischemic cellular damage probably through the activation of MEF2C transcription factor.

Human L-type amino acid transporter 1(LAT1):/characterization of function and expression in tumor cell lines,
Biochimica et Biophysica Acta (BBA) - Biomembranes, Vol.1514, No.2, 291-302, 2001.

(要約): System L is a major nutrient transport system responsible for the transport of large neutral amino acids including several essential amino acids. We previously identified a transporter (L-type amino acid transporter 1: LAT1) subserving system L in C6 rat glioma cells and demonstrated that LAT1 requires 4F2 heavy chain (4F2hc) for its functional expression. Since its oncofetal expression was suggested in the rat liver, it has been proposed that LAT1 plays a critical role in cell growth and proliferation. In the present study, we have examined the function of human LAT1 (hLAT1) and its expression in human tissues and tumor cell lines. When expressed in Xenopus oocytes with human 4F2hc (h4F2hc), hLAT1 transports large neutral amino acids with high affinity (K(m)= approximately 15- approximately 50 microM) and L-glutamine and L-asparagine with low affinity (K(m)= approximately 1.5- approximately 2 mM). hLAT1 also transports D-amino acids such as D-leucine and D-phenylalanine. In addition, we show that hLAT1 accepts an amino acid-related anti-cancer agent melphalan. When loaded intracellularly, L-leucine and L-glutamine but not L-alanine are effluxed by extracellular substrates, confirming that hLAT1 mediates an amino acid exchange. hLAT1 mRNA is highly expressed in the human fetal liver, bone marrow, placenta, testis and brain. We have found that, while all the tumor cell lines examined express hLAT1 messages, the expression of h4F2hc is varied particularly in leukemia cell lines. In Western blot analysis, hLAT1 and h4F2hc have been confirmed to be linked to each other via a disulfide bond in T24 human bladder carcinoma cells. Finally, in in vitro translation, we show that hLAT1 is not a glycosylated protein even though an N-glycosylation site has been predicted in its extracellular loop, consistent with the property of the classical 4F2 light chain. The properties of the hLAT1/h4F2hc complex would support the roles of this transporter in providing cells with essential amino acids for cell growth and cellular responses, and in distributing amino acid-related compounds.

Hypophosphatemic rickets accompanying McCune Albright syndrome: evidence that a humoral factor causes hypophosphatemia,
Journal of Bone and Mineral Metabolism, Vol.19, No.5-6, 287-295, 2001.

(要約): McCune-Albright syndrome (MAS) is sometimes complicated by hypophosphatemia. However, it remains unclear whether a humoral factor is associated with the cause of hypophosphatemia. We isolated cells with mutations of the Gsalpha gene from fibrous bone dysplasia tissues of two MAS patients (MAS cells). Severe combined immunodeficiency (SCID) mice were subjected to experiments using from one of these cells patients. Effects of conditioned media (CM) isolated from MAS cells (MAS-CM) on phosphate transport were investigated by using rat renal slices, the renal cell line OK-B, rat intestinal rings and the human intestinal cell line Caco-2. In addition, the effects of MAS-CM on human sodium-dependent phosphate transporter (NPT2) gene promoter activity expression were investigated in the renal cell line OK-B2400 and were compared with the effects of CM isolated from a patient with oncogenic hypophosphatemic osteomalacia (OHO). MAS cells caused significant hypophosphatemia (P < 0.05) and elevated serum alkaline phosphatase activity (P < 0.05) in SCID mice. The MAS-CM significantly inhibited phosphate uptake in everted intestinal rings (P < 0.01), whereas it had no effect on glucose uptake. The MAS-CM had no effect on either phosphate uptake in the kidney or NPT2 gene promoter activity. In contrast, the CM of the OHO patient significantly inhibited phosphate uptake and NPT2 gene promoter activity. These results indicate that the humoral factor derived from fibrous dysplasia cells of the MAS patient is different to that from OHO patients, because the humoral factor from the MAS patient inhibited phosphate transport not in the kidney but in the intestine.

A neutrophil elastase inhibitor (ONO-5046) reduces neurologic damage after spinal cord injury in rats,
Journal of Neurochemistry, Vol.78, No.5, 1064-1072, 2001.

(要約): In view of a cytoprotective effect of elastase inhibitor on chemokine-mediated tissue injury, we examined the neuroprotective effect of ONO-5046, a specific inhibitor of neutrophil elastase, in rats with spinal cord injury. Standardized spinal cord compression markedly increased cytokine-induced neutrophil chemo-attractant (CINC)-1 mRNA and protein. Their increases correlated with neurologic severity of injured rats. Immunohistochemically, CINC-1 protein was detected sequentially in vascular endothelial cells at 4 h, in perivascular neutrophils at 8 h, and in neutrophils infiltrating into cord substance at 12 h. Pretreatment with ONO-5046 (50 mg/kg) markedly ameliorated motor disturbance in injured rats, and reduced CINC-1 protein and mRNA expression. ONO-5046 also significantly reduced the increase of neutrophil accumulation or infiltration estimated by myeloperoxidase activity, and the extent of vascular permeability by Evans blue extravasation in the injured cord segment in comparison to control animals receiving vehicle. These results suggest that CINC-1 contributed to inflammation in rat spinal cord injury and ONO-5046 attenuated neurologic damage partly by blocking CINC-1 production of the chemoattractant, preventing neutrophil activation and vascular endothelial cell injury.

Effects of alendronate on bone metastases and hypercarcemia after surgery for hepatocellular carcinoma,
Japanese Journal of Clinical Oncology, Vol.30, No.9, 410-413, 2000.

(要約): Alendronate, a bisphosphonate compound, lowers serum calcium in patients with cancer-associated hypercalcemia through its inhibitory effect on bone resorption and as a result symptoms associated with hypercalcemia improve. This study was carried out to investigate the effects of alendronate in patients with hypercalcemia due to bone metastasis of hepatocellular carcinoma (HCC). Two patients were evaluated. Their corrected serum calcium and alpha-fetoprotein (AFP) levels and their computed tomography (CT), bone scintigraphy and magnetic resonance imaging (MRI) findings were evaluated before and during alendronate treatment. After treatment, not only the corrected serum calcium levels but also AFP levels and bone pain decreased; in addition, the regression of the metastatic focus was noted in the MRI analysis. These tumor inhibitory effects of alendronate have not been reported in HCC before; and alendronate might serve to prevent bone metastases in patients with HCC. In conclusion, two patients who developed hypercalcemia associated with bone metastasis after surgery for HCC were treated with alendronate and they experienced alleviation of the pain due to bone metastasis, improvement of their quality of life and a marked decrease in AFP levels with tumor regression.

Daily pattern of energy metabolism in cirrhosis.,
Nutrition, Vol.15, No.10, 749-754, 1999.

(要約): The daily pattern of energy expenditure and the oxidation rates of carbohydrates, fats, and protein were evaluated by indirect calorimetry in 18 control subjects (Group 1) and 34 cirrhotic patients who were divided into Groups 2a and 2b showing indocyanin green retention rates at 15 min of <30% and 30% or more, respectively. The ratio of resting energy expenditure to basal energy expenditure (%REE) was higher in the cirrhotic patients than in the controls at 8:30 AM and 2:30 PM. The oxidation rates of carbohydrates and fats under fasting conditions in Group 2b patients were respectively lower, and higher than in Group 1 and 2a patients. After the subjects ate, glucose became the substrate preferentially metabolized, and the proportion of fat metabolized was reduced from 82.9+/-5.1% to 43.9+/-21.9% and from 70.7+/-14.1% to 46.8+/-13.9% in the patients with advanced and less advanced cirrhosis, respectively, and from 59.4+/-27.2% to 48.4+/-18.5% in the controls. The fasting concentrations of non-esterified fatty acids in Group 2b were also significantly higher than those in the Group 1 and Group 2a patients. After eating, these concentrations fell and reached similar levels in the patients and controls. These data indicated that the patients with cirrhosis developed the catabolic state of starvation in the morning because of a lack of glycogen stores. Therefore, frequent meal supplementation to prevent early-onset starvation and energy deficiency may be advisable in such patients to maintain a well-nourished condition.

Total parenteral nutrition on energy metabolism in children undergoing autologous peripheral blood stem cell transplantation.,
The Journal of Medical Investigation : JMI, Vol.44, No.3-4, 199-203, 1998.

(要約): The resting energy expenditure (REE) and the respiratory quotient (RQ) were measured longitudinally using indirect calorimetry to examine the effects of total parenteral nutrition (TPN) on energy metabolism in children undergoing autologous peripheral blood stem cell transplantation (PBSCT). There were six children (two males and four females) and the age ranged from five to 13 years (median, eight yrs). The diagnosis included acute lymphocytic leukemia (ALL; 4), neuroblastoma (NBL; 1) and primitive neuroectodermal tumor (PNET; 1). TPN was started after the patients were stabilized following PBSCT (group A; n = 3) or before the initiation of high-dose cytoreductive chemotherapy (HCC) (group B; n = 3). Duration of HCC before PBSCT was identical between the two groups (six to eight days). Average total calorie and protein intake during HCC was significantly higher for group B than for group A. The %REE, the percentage of REE to the predicted basal energy expenditure (BEE), in group A showed 133 +/- 19%, 129 +/- 14% and 146 +/- 11% during three periods of HCC (days -8 to -1 of PBSCT), bone marrow suppression (days 0 to 11 of PBSCT) and bone marrow recovery (days 12 to 22 of PBSCT), respectively. In contrast, those in group B were 10% to 20% lower than those in group A at all periods. Carbohydrate oxidation rates during HCC in group A were significantly lower than those in group B, and those were not different between both groups during post-PBSCT periods. Fat oxidation rates in both groups were similar at all stages of periods. In contrast, protein degradation rates in group A were significantly higher than those in group B at all stages of the period. From these results, we concluded that commencement of TPN administration prior to HCC in the patients undergoing PBSCT provides beneficial effects to maintain better energy metabolic and nutritional status.

Comparison of energy metabolism in insulin-dependent and non-insulin-dependent diabetes mellitus,
The Journal of Medical Investigation : JMI, Vol.44, No.1-2, 67-71, 1997.

(要約): To compare the metabolic consequences of insulin-dependent diabetes mellitus (IDDM) and non-insulin-dependent diabetes mellitus (NIDDM), glycemic control and energy metabolism were evaluated in 18 children displaying IDDM and 19 NIDDM adult patients. With rising concentrations of fasting blood glucose (FBG), hemoglobin A1C and free fatty acid, the percentage of the ratio of resting energy expenditure (REE) to predicted REE expressed as %REE increased and the respiratory quotient (RQ) decreased. The linear regression between RQ and FBG showed the same gradient in IDDM and NIDDM although the RQ in IDDM was always 0.07 lower than that in NIDDM given various FBG concentrations. Those patients whose RQ values were less than 0.7, indicating ketone body production, included 8 (44%) IDDM and 2 (11%) NIDDM patients. These results may explain the relatively greater manifestation of ketoacidosis in IDDM.

Phosphate restriction in diet therapy.,
Contributions to Nephrology, Vol.155, 113-124, 2007.

(要約): Hyperphosphatemia and hyperparathyroidism, frequently observed in patients with endstage renal disease, are associated with renal osteodystrophy, organ calcification, cardiovascular disease and sudden death. Restriction of dietary protein and phosphorus is beneficial in slowing the progression of renal failure. Dietary phosphorus restriction must be prescribed at all stages of renal failure in adults. It may be achieved by decreasing protein intake and avoiding foods rich in phosphorus. An average of 60-80% of the phosphorus intake is absorbed in the gut in dialysis patients. If phosphate binders are employed, the phosphorus absorbed from the diet may be reduced to 40%. Conventional hemodialysis with a high-flux, high-efficiency dialyzer removes approximately 30 mmol (900 mg) phosphorus during each dialysis performed three times weekly. Therefore, 750 mg of phosphorus intake should be the critical value above which a positive balance of phosphorus may occur. This value corresponds to a protein diet of 45-50 g/day or 0.8 g/kg body weight/day for a 60 kg patient. Target levels should become 9.2-9.6 mg/dl for calcium, 2.5-5.5 mg/dl for phosphorus, <55 mg2/dl2 for the calcium-phosphorus product, and 100-200 pg/ml for intact parathyroid hormone.

Gene expression in low glycemic index diet - impact on metabolic control.,
Forum of Nutrition, Vol.60, 127-139, 2007.

(要約): Correcting postprandial hyperglycemia forms an important part of the prevention and management of type 2 diabetes. A low-glycemic-index liquid formula designated as Inslow was prepared by replacing dextrin in the standard balanced formula (SBF) with 55.7% palatinose. Long-term administration of Inslow prevented fatty liver and improved insulin resistance in rats. Expressions of mRNA of factors involved in glucose and lipid metabolism were determined to clarify its mechanism. Analysis of mRNA expressions revealed that Inslow increased the expression of enzymes involved in Beta -oxidation and peroxisome proliferator-activated receptor-alpha (PPAR-alpha) in the liver, and increased PPAR-gamma, adiponectin and uncoupling protein 2 as well as decreased tumor necrosis factor alpha in adipose tissue in comparison with those of SBF. Inslow may induce improvement of insulin resistance by accelerated Beta-oxidation through increased expression of the hepatic PPAR-alpha gene and adipocyte PPAR-gamma gene. Therefore, Inslow is a functional food which prevents and treats type 2 diabetes.

ビタミン, Vol.89, No.8, 393-396, 2015年8月.

(要約): The phosphate (Pi)-mediated signal transduction pathways in renal proximal tubular cells and endothelial cells were examined, because Pi depletion and overloading are known to influence gene expression and cellular function. In renal proximal tubular calls (LLC-PK1), Pi depletion resulted in increases in intracellular inositol triphosphate (IP3) and calcium ion (Ca^<2+>) levels, the latter of which may be associated with the maintenance of Pi homeostasis. On the other hand, exposing bovine aortic endothelial cells to excessive Pi load increased production of reactive oxygen species, which depended on phosphorus influx via sodium-dependent phosphate transporters, and decreased nitric oxide production via inhibitory phosphorylation of endothelial nitric oxide synthase. Pi loading in rat aortic rings inhibited endothelium-dependent vasodilation. A high dietary Pi load in human subjects increased serum Pi level at 2 h and significantly decreased flow-mediated dilation. Thus, it was found that the function of endothelial cells was damaged by the high dietary Pi loading. Taken together, these findings suggest that the changes in serum Pi level are associated with human health by affecting the intracellular Pi signal transduction pathway.

ビタミン, Vol.88, No.10, 499-506, 2014年10月.

(要約): Nutritional science of vitamin D in pediatric and adult diseases was summarized. Vitamin D-dependency type II is a rare disease caused by a disorder of the human vitamin D receptor (VDR). Except for the alopecia, severe rickets and other biochemical abnormalities of 6 patients were reversed by treatment with 3 g/kg/d of 1-hydroxyvitamin D_3. A polymorphism at the translation initiation codon of the human VDR gene also affects the bone mineral density (BMD) in Japanese. Attention to phosphorus intake is important because both phosphorus deficiency and overloading impair bone health and quality of life (QOL). Elevation of extracellular phosphorus level causes endothelial dysfunction and medial calcification, which are closely associated with the development of cardiovascular disease (CVD). A dietary approach to limit phosphorus intake is particularly important to prevent bone impairment and CVD in patients with chronic kidney disease (CKD). Increased serum fibroblast growth factor 23 (FGF23)level is an early finding of abnormal mineral metabolism in CKD which causes secondary hyperparathyroidism and resistance of the parathyroid gland to the action of FGF23. In order to improve bone health and QOL in the general population, it should be important that attention to phosphorous intake from processed foods containing phosphorus additive is paied.

(要約): Severe and prolonged stress exposure impairs homeostatic mechanisms, particularly associatedwith the onset of depressive illness. Brain food is aimed at preventing as well as treating a growingnumber of depression. An increase in brain tryptophan levels on the order of that produced byeating a carbohydrate-rich/protein-poor meal causes parallel increases in the amounts of serotoninreleased into synapses. Dietary antioxidants present in fruits and vegetables may also improvemood. Furthermore, lifestyle of breakfast, lunch and dinner with family or friends is a very importantfactor to reduce depression.

1α,25-Dihydroxyvitamin D₃ is a preventive factor in the metastasis of lung cancer,
Carcinogenesis, Vol.26, No.2, 429-440, Feb. 2005.

(要約): 1alpha,25-Dihydroxyvitamin D(3) [1alpha,25(OH)(2)D(3)], the major regulator of calcium homeostasis, has potent antiproliferative and anti-invasive properties in vitro in cancer cells. Studies in vivo demonstrated that 1alpha,25(OH)(2)D(3) slows the progression of breast, prostate and other carcinomas. A key question is whether 1alpha,25(OH)(2)D(3) exerts its anticarcinogenic effects in vivo by a mechanism that is dependent on its capacity to limit the proliferation and invasiveness of cancer cells in vitro. It has not been clear whether the calcemic activity and regulation of the host defenses by 1alpha,25(OH)(2)D(3) contribute to the effect on cancer cells. In this study we have focused on the influence of 1alpha,25(OH)(2)D(3) on the metastasis of lung cancer, without involvement of the calcemic activity and other effects of 1alpha,25(OH)(2)D(3) in the host. We used metastatic Lewis lung carcinoma cells expressing green fluorescent protein (LLC-GFP cells) and examined metastatic activity in vitamin D receptor (VDR) null mutant (VDR(-/-)) mice and their wild-type counterparts (VDR(+/+) mice). VDR(-/-) mice exhibit hypocalcemia and extremely high serum levels of 1alpha,25(OH)(2)D(3). We expected that serum 1alpha,25(OH)(2)D(3) would act in vivo to directly inhibit the metastatic growth of VDR-positive LLC-GFP cells in VDR(-/-) mice. The metastatic activities of LLC-GFP cells were remarkably reduced in VDR(-/-) mice compared with VDR(+/+) mice. To test the hypothesis that serum 1alpha,25(OH)(2)D(3) is an intrinsic factor that inhibits metastatic growth of lung cancer cells, we corrected hypocalcemia and/or hypervitaminosis D in VDR(-/-) mice by dietary manipulation. The metastatic growth of LLC-GFP cells was remarkably reduced in response to serum levels of 1alpha,25(OH)(2)D(3), but not to serum calcium levels. Furthermore, we found that VDR(+/+) mice fed the manipulated diets displayed an apparent inverse relationship between the physiological levels of serum 1alpha,25(OH)(2)D(3) (8-15 pg/ml) and tumorigenesis. Here we show that 1alpha,25(OH)(2)D(3) inhibits the metastatic growth of lung cancer cells in a defined animal model.

The regulation and function of phosphate in the human body,
BioFactors, Vol.21, No.1-4, 345-355, 2004.

(要約): Inorganic phosphate (Pi) is required for cellular function and skeletal mineralization. Serum Pi level is maintained within a narrow range through a complex interplay between intestinal absorption, exchange with intracellular and bone storage pools, and renal tubular reabsorption. Pi is abundant in the diet, and intestinal absorption of Pi is efficient and minimally regulated. The kidney is a major regulator of Pi homeostasis and can increase or decrease its Pi reabsorptive capacity to accommodate Pi need. The crucial regulated step in Pi homeostasis is the transport of Pi across the renal proximal tubule. Type II sodium-dependent phosphate (Na/Pi) cotransporter (NPT2) is the major molecule in the renal proximal tubule and is regulated by hormones and nonhormonal factors. Recent studies of inherited and acquired hypophosphatemia which exhibit similar biochemical and clinical features, have led to the identification of novel genes, phosphate regulating gene with homologies to endopeptidases on the X chromosome (PHEX) and fibroblast growth factor-23 (FGF-23), that play a role in the regulation of Pi homeostasis. The PHEX gene encodes an endopeptidase, predominantly expressed in bone and teeth but not in kidney. FGF-23 may be a substrate of this endopeptidase and inhibit renal Pi reabsorption. In a survey in the United States and in Japan, the amount of phosphorus from food is gradually increasing. It is thought that excess amounts of phosphorus intake for long periods are a strong factor in bone impairment and ageing. The restriction of phosphorus intake seems to be important under low calcium intake to keep QOL on high level.

(要約): PTHは，IIa 型リントランスポーターのエンドサイトーシスを誘導することによって腎臓のリン再吸収を抑制する．PTHは刷子縁膜および基底膜に局在するPTH受容体を介して，PKAあるいはPKCの活性化を促進する．これらのシグナル伝達の活性化は，直接NPT2をリン酸化するのではなく，エンドサイトーシスに関連する分子がPTHの作用に重要な役割を果たしていると考えられる．

Evaluation of anti-stress nutrients in the endothelial cells with fluorescence indicator,
The Journal of Medical Investigation : JMI, Vol.52, No.Supplement, 295-296, Tokushima, Nov. 2005.

(要約): Oxidative stress has emerged as an important pathogenic factor in the development of long-term complications, such as hypertension, atherosclerosis, nephropathy, and cancer. Taking many antioxidants from natural food may be effective to prevent us from those diseases. We have attempted to evaluate the effect of improvement by dietary antioxidants on the endothelial dysfunction induced by hyperglycemia. Fluorescence indicators for reactive oxygen species and nitric oxide were employed to the evaluation. The combination of those fluorescence indicators could be powerful tool to evaluate the effect of anti-stress nutrients on both oxidative stress and endothelial dysfunction.

Control of oxidative stress and metabolic homeostasis by the suppression of postprandial hyperglycemia,
The Journal of Medical Investigation : JMI, Vol.52 Suppl, 259-265, Nov. 2005.

(要約): Repeated mental stress may lead to chronic alterations in cortisol and catecholamine concentrations and to insulin resistance. Furthermore, chronically elevated cortisol concentrations may favour the development of abdominal obesity and of the metabolic syndrome. Oxidative stress impairs glucose uptake in muscle and fat and correlates with BMI. Obese subjects with type 2 diabetes, especially soon after the onset of diabetes, usually exhibit postprandial hyperglycemia with delayed hyperinsulinemia. It is recognized that insulin resistance causes postprandial hyperglycemia; however, it is also possible that impairment of early insulin secretion in response to an oral glucose load is the reason why postprandial hyperglycemia occurs. Since even modest increases in postprandial glucose values can be a risk factor for cardiovascular disease. Therefore, the effects of palatinose based functional food which reduces postprandial hyperglycemia and hyperinsulinemia were investigated in rats. This novel food definitely reduced visceral fat accumulation and improved insulin sensitivity. Therefore, it is suggested that functional food which suppresses postprandial glucose level is beneficial for both stress and metabolic controls.

Human nutritional science on stress control,
The Journal of Medical Investigation : JMI, Vol.52 Supplement, 223-224, Nov. 2005.

(要約): Severe and prolonged stress exposure impairs homeostatic mechanisms, particularly associated with the onset of depressive illness. The establishment of functional foods that correctly regulate stress response must be an important and new field for human nutrition. This exciting science has been vigorously achieving in the 21st century COE program of University of Tokushima Graduate School.
