Involvement of the scalloped gene in morphogenesis of the wing margin via regulating cell growth in a hemimetabolous insect Gryllus bimaculatus.,
Development Growth & Differentiation, Vol.65, No.6, 348-359, 2023.

(要約): The acquisition of wings was a key event in insect evolution. As hemimetabolous insects were the first group to acquire functional wings, establishing the mechanisms of wing formation in this group could provide useful insights into their evolution. In this study, we aimed to elucidate the expression and function of the gene scalloped (sd), which is involved in wing formation in Drosophila melanogaster, and in Gryllus bimaculatus mainly during postembryonic development. Expression analysis showed that sd is expressed in the tergal edge, legs, antennae, labrum, and cerci during embryogenesis and in the distal margin of the wing pads from at least the sixth instar in the mid to late stages. Because sd knockout caused early lethality, nymphal RNA interference experiments were performed. Malformations were observed in the wings, ovipositor, and antennae. By analyzing the effects on wing morphology, it was revealed that sd is mainly involved in the formation of the margin, possibly through the regulation of cell proliferation. In conclusion, sd might regulate the local growth of wing pads and influence wing margin morphology in Gryllus.

Combinatorial expression of ebony and tan generates body color variation from nymph through adult stages in the cricket, Gryllus bimaculatus.,
PLoS ONE, Vol.18, No.5, 2023.

(要約): Insect body colors and patterns change markedly during development in some species as they adapt to their surroundings. The contribution of melanin and sclerotin pigments, both of which are synthesized from dopamine, to cuticle tanning has been well studied. Nevertheless, little is known about how insects alter their body color patterns. To investigate this mechanism, the cricket Gryllus bimaculatus, whose body color patterns change during postembryonic development, was used as a model in this study. We focused on the ebony and tan genes, which encode enzymes that catalyze the synthesis and degradation, respectively, of the precursor of yellow sclerotin N-β-alanyl dopamine (NBAD). Expression of the G. bimaculatus (Gb) ebony and tan transcripts tended to be elevated just after hatching and the molting period. We found that dynamic alterations in the combined expression levels of Gb'ebony and Gb'tan correlated with the body color transition from the nymphal stages to the adult. The body color of Gb'ebony knockout mutants generated by CRISPR/Cas9 systemically darkened. Meanwhile, Gb'tan knockout mutants displayed a yellow color in certain areas and stages. The phenotypes of the Gb'ebony and Gb'tan mutants probably result from an over-production of melanin and yellow sclerotin NBAD, respectively. Overall, stage-specific body color patterns in the postembryonic stages of the cricket are governed by the combinatorial expression of Gb'ebony and Gb'tan. Our findings provide insights into the mechanism by which insects evolve adaptive body coloration at each developmental stage.

Evolutionarily conserved function of the even-skipped ortholog in insects revealed by gene knock-out analyses in Gryllus bimaculatus.,
Developmental Biology, Vol.485, 1-8, 2022.

(要約): Comparing the developmental mechanisms of segmentation among insects with different modes of embryogenesis provides insights on how the function of segmentation genes evolved. Functional analysis of eve by genetic mutants shows that the Drosophila pair-rule gene, even-skipped (eve), contributes to initial segmental patterning. However, eve orthologs tends to have diverse functions in other insects. To compare the evolutionary functional divergence of this gene, we evaluated eve function in a phylogenetically basal insect, the cricket Gryllus bimaculatus. To investigate the phenotypic effects of eve gene knock-out, we generated CRISPR/Cas9 system-mediated mutant strains of the cricket. CRISPR/Cas9 mutagenesis of multiple independent sites in the eve coding region revealed that eve null mutant embryos were defective in forming the gnathal, thoracic, and abdominal segments, consequently shortening the anterior-posterior axis. In contrast, the structures of the anterior and posterior ends (e.g., antenna, labrum, and cercus) formed normally. Hox gene expression in the gnathal, thoracic, and abdominal segments was detected in the mutant embryos. Overall, this study showed that Gryllus eve plays an important role in embryonic elongation and the formation of segmental boundaries in the gnathal to abdominal region of crickets. In the light of studies on other species, the eve function shown in Gryllus might be ancestral in insects.

Toll signalling promotes blastema cell proliferation during cricket leg regeneration via insect macrophages.,
Development, Vol.149, No.8, 2022.

(要約): Hemimetabolous insects, such as the two-spotted cricket Gryllus bimaculatus, can recover lost tissues, in contrast to the limited regenerative abilities of human tissues. Following cricket leg amputation, the wound surface is covered by the wound epidermis, and plasmatocytes, which are insect macrophages, accumulate in the wound region. Here, we studied the function of Toll-related molecules identified by comparative RNA sequencing during leg regeneration. Of the 11 Toll genes in the Gryllus genome, expression of Toll2-1, Toll2-2 and Toll2-5 was upregulated during regeneration. RNA interference (RNAi) of Toll, Toll2-1, Toll2-2, Toll2-3 or Toll2-4 produced regeneration defects in more than 50% of crickets. RNAi of Toll2-2 led to a decrease in the ratio of S- and M-phase cells, reduced expression of JAK/STAT signalling genes, and reduced accumulation of plasmatocytes in the blastema. Depletion of plasmatocytes in crickets using clodronate also produced regeneration defects, as well as fewer proliferating cells in the regenerating legs. Plasmatocyte depletion also downregulated the expression of Toll and JAK/STAT signalling genes in the regenerating legs. These results suggest that Spz-Toll-related signalling in plasmatocytes promotes leg regeneration through blastema cell proliferation by regulating the Upd-JAK/STAT signalling pathway.

Insights into the genomic evolution of insects from cricket genomes.,
Communications Biology, Vol.4, No.1, 2021.

(要約): Most of our knowledge of insect genomes comes from Holometabolous species, which undergo complete metamorphosis and have genomes typically under 2 Gb with little signs of DNA methylation. In contrast, Hemimetabolous insects undergo the presumed ancestral process of incomplete metamorphosis, and have larger genomes with high levels of DNA methylation. Hemimetabolous species from the Orthopteran order (grasshoppers and crickets) have some of the largest known insect genomes. What drives the evolution of these unusual insect genome sizes, remains unknown. Here we report the sequencing, assembly and annotation of the 1.66-Gb genome of the Mediterranean field cricket Gryllus bimaculatus, and the annotation of the 1.60-Gb genome of the Hawaiian cricket Laupala kohalensis. We compare these two cricket genomes with those of 14 additional insects and find evidence that hemimetabolous genomes expanded due to transposable element activity. Based on the ratio of observed to expected CpG sites, we find higher conservation and stronger purifying selection of methylated genes than non-methylated genes. Finally, our analysis suggests an expansion of the pickpocket class V gene family in crickets, which we speculate might play a role in the evolution of cricket courtship, including their characteristic chirping.

Regulatory mechanisms underlying the specification of the pupal-homologous stage in a hemimetabolous insect,
Philosophical Transactions of the Royal Society of London. Series B, Biological Sciences, Vol.374, No.1783, 20190225, 2019.

(要約): Juvenile hormones and the genetic interaction between the transcription factors Krüppel homologue 1 (Kr-h1) and Broad (Br) regulate the transformation of insects from immature to adult forms in both types of metamorphosis (holometaboly with a pupal stage versus hemimetaboly with no pupal stage); however, knowledge about the exact instar in which this occurs is limited. Using the hemimetabolous cricket Gryllus bimaculatus (Gb), we demonstrate that a genetic interaction occurs among Gb'Kr-h1, Gb'Br and the adult-specifier transcription factor Gb'E93 from the sixth to final (eighth) nymphal instar. Gb'Kr-h1 and Gb'Br mRNAs were strongly expressed in the abdominal tissues of sixth instar nymphs, with precocious adult moults being induced by Gb'Kr-h1 or Gb'Br knockdown in the sixth instar. The depletion of Gb'Kr-h1 or Gb'Br upregulates Gb'E93 in the sixth instar. By contrast, Gb'E93 knockdown at the sixth instar prevents nymphs transitioning to adults, instead producing supernumerary nymphs. Gb'E93 also represses Gb'Kr-h1 and Gb'Br expression in the penultimate nymphal instar, demonstrating its important role in adult differentiation. Our results suggest that the regulatory mechanisms underlying the pupal transition in holometabolous insects are evolutionarily conserved in hemimetabolous G. bimaculatus, with the penultimate and final nymphal periods being equivalent to the pupal stage. This article is part of the theme issue 'The evolution of complete metamorphosis'.

Bone morphogenetic protein signaling in distal patterning and intercalation during leg regeneration of the cricket, Gryllus bimaculatus,
Development Growth & Differentiation, Vol.60, No.6, 377-386, 2018.

(要約): The cricket, Gryllus bimaculatus, is a classic model of leg regeneration following amputation. We previously demonstrated that Gryllus decapentaplegic (Gb'dpp) is expressed during leg regeneration, although it remains unclear whether it is essential for this process. In this study, double-stranded RNA targeting the Smad mathers-against-dpp homolog, Gb'mad, was used to examine the role of bone morphogenetic protein (BMP) signaling in the leg regeneration process of Gryllus bimaculatus. RNA interference (RNAi)-mediated knockdown of Gb'mad led to a loss of tarsus regeneration at the most distal region of regenerating leg segments. Moreover, we confirmed that the phenotype obtained by knockdown of Dpp type I receptor, Thick veins (Gb'tkv), closely resembled that observed for Gb'mad RNAi crickets, thereby suggesting that the BMP signaling pathway is indispensable for the initial stages of tarsus formation. Interestingly, knockdown of Gb'mad and Gb'tkv resulted in significant elongation of regenerating tibia along the proximodistal axis compared with normal legs. Moreover, our findings indicate that during the regeneration of tibia, the BMP signaling pathway interacts with Dachsous/Fat (Gb'Ds/Gb'Ft) signaling and dachshund (Gb'dac) to re-establish positional information and regulate determination of leg size. Based on these observations, we discuss possible roles for Gb'mad in the distal patterning and intercalation processes during leg regeneration in Gryllus bimaculatus.

Roles of OA1 octopamine receptor and Dop1 dopamine receptor in mediating appetitive and aversive reinforcement revealed by RNAi studies.,
Scientific Reports, Vol.6, 29696, 2016.

(要約): Revealing reinforcing mechanisms in associative learning is important for elucidation of brain mechanisms of behavior. In mammals, dopamine neurons are thought to mediate both appetitive and aversive reinforcement signals. Studies using transgenic fruit-flies suggested that dopamine neurons mediate both appetitive and aversive reinforcements, through the Dop1 dopamine receptor, but our studies using octopamine and dopamine receptor antagonists and using Dop1 knockout crickets suggested that octopamine neurons mediate appetitive reinforcement and dopamine neurons mediate aversive reinforcement in associative learning in crickets. To fully resolve this issue, we examined the effects of silencing of expression of genes that code the OA1 octopamine receptor and Dop1 and Dop2 dopamine receptors by RNAi in crickets. OA1-silenced crickets exhibited impairment in appetitive learning with water but not in aversive learning with sodium chloride solution, while Dop1-silenced crickets exhibited impairment in aversive learning but not in appetitive learning. Dop2-silenced crickets showed normal scores in both appetitive learning and aversive learning. The results indicate that octopamine neurons mediate appetitive reinforcement via OA1 and that dopamine neurons mediate aversive reinforcement via Dop1 in crickets, providing decisive evidence that neurotransmitters and receptors that mediate appetitive reinforcement indeed differ among different species of insects.

TGF-β signaling in insects regulates metamorphosis via juvenile hormone biosynthesis.,
Proceedings of the National Academy of Sciences of the United States of America, Vol.113, No.20, 5634-5639, 2016.

(要約): Although butterflies undergo a dramatic morphological transformation from larva to adult via a pupal stage (holometamorphosis), crickets undergo a metamorphosis from nymph to adult without formation of a pupa (hemimetamorphosis). Despite these differences, both processes are regulated by common mechanisms that involve 20-hydroxyecdysone (20E) and juvenile hormone (JH). JH regulates many aspects of insect physiology, such as development, reproduction, diapause, and metamorphosis. Consequently, strict regulation of JH levels is crucial throughout an insect's life cycle. However, it remains unclear how JH synthesis is regulated. Here, we report that in the corpora allata of the cricket, Gryllus bimaculatus, Myoglianin (Gb'Myo), a homolog of Drosophila Myoglianin/vertebrate GDF8/11, is involved in the down-regulation of JH production by suppressing the expression of a gene encoding JH acid O-methyltransferase, Gb'jhamt In contrast, JH production is up-regulated by Decapentaplegic (Gb'Dpp) and Glass-bottom boat/60A (Gb'Gbb) signaling that occurs as part of the transcriptional activation of Gb'jhamt Gb'Myo defines the nature of each developmental transition by regulating JH titer and the interactions between JH and 20E. When Gb'myo expression is suppressed, the activation of Gb'jhamt expression and secretion of 20E induce molting, thereby leading to the next instar before the last nymphal instar. Conversely, high Gb'myo expression induces metamorphosis during the last nymphal instar through the cessation of JH synthesis. Gb'myo also regulates final insect size. Because Myo/GDF8/11 and Dpp/bone morphogenetic protein (BMP)2/4-Gbb/BMP5-8 are conserved in both invertebrates and vertebrates, the present findings provide common regulatory mechanisms for endocrine control of animal development.

Regenerated leg segment patterns are regulated epigenetically by histone H3K27 methylation in the cricket Gryllus bimaculatus,
Development, Vol.142, No.17, 2916-2927, 2015.

(要約): Hemimetabolous insects such as the cricket Gryllus bimaculatus regenerate lost tissue parts using blastemal cells, a population of dedifferentiated proliferating cells. The expression of several factors that control epigenetic modification is upregulated in the blastema compared with differentiated tissue, suggesting that epigenetic changes in gene expression might control the differentiation status of blastema cells during regeneration. To clarify the molecular basis of epigenetic regulation during regeneration, we focused on the function of the Gryllus Enhancer of zeste [Gb'E(z)] and Ubiquitously transcribed tetratricopeptide repeat gene on the X chromosome (Gb'Utx) homologues, which regulate methylation and demethylation of histone H3 lysine 27 (H3K27), respectively. Methylated histone H3K27 in the regenerating leg was diminished by Gb'E(z)(RNAi) and was increased by Gb'Utx(RNAi). Regenerated Gb'E(z)(RNAi) cricket legs exhibited extra leg segment formation between the tibia and tarsus, and regenerated Gb'Utx(RNAi) cricket legs showed leg joint formation defects in the tarsus. In the Gb'E(z)(RNAi) regenerating leg, the Gb'dac expression domain expanded in the tarsus. By contrast, in the Gb'Utx(RNAi) regenerating leg, Gb'Egfr expression in the middle of the tarsus was diminished. These results suggest that regulation of the histone H3K27 methylation state is involved in the repatterning process during leg regeneration among cricket species via the epigenetic regulation of leg patterning gene expression.

Short germ insects utilize both the ancestral and derived mode of Polycomb group-mediated epigenetic silencing of Hox genes.,
Biology Open, Vol.4, No.6, 702-709, 2015.

(要約): In insect species that undergo long germ segmentation, such as Drosophila, all segments are specified simultaneously at the early blastoderm stage. As embryogenesis progresses, the expression boundaries of Hox genes are established by repression of gap genes, which is subsequently replaced by Polycomb group (PcG) silencing. At present, however, it is not known whether patterning occurs this way in a more ancestral (short germ) mode of embryogenesis, where segments are added gradually during posterior elongation. In this study, two members of the PcG family, Enhancer of zeste (E(z)) and Suppressor of zeste 12 (Su(z)12), were analyzed in the short germ cricket, Gryllus bimaculatus. Results suggest that although stepwise negative regulation by gap and PcG genes is present in anterior members of the Hox cluster, it does not account for regulation of two posterior Hox genes, abdominal-A (abd-A) and Abdominal-B (Abd-B). Instead, abd-A and Abd-B are predominantly regulated by PcG genes, which is the mode present in vertebrates. These findings suggest that an intriguing transition of the PcG-mediated silencing of Hox genes may have occurred during animal evolution. The ancestral bilaterian state may have resembled the current vertebrate mode of regulation, where PcG-mediated silencing of Hox genes occurs before their expression is initiated and is responsible for the establishment of individual expression domains. Then, during insect evolution, the repression by transcription factors may have been acquired in anterior Hox genes of short germ insects, while PcG silencing was maintained in posterior Hox genes.

Involvement of dachshund and Distal-less in distal pattern formation of the cricket leg during regeneration.,
Scientific Reports, Vol.5, 8387, 2015.

(要約): Cricket nymphs have the remarkable ability to regenerate a functional leg following amputation, indicating that the regenerating blastemal cells contain information for leg morphology. However, the molecular mechanisms that underlie regeneration of leg patterns remain poorly understood. Here, we analyzed phenotypes of the tibia and tarsus (three tarsomeres) obtained by knockdown with regeneration-dependent RNA interference (rdRNAi) against Gryllus dachshund (Gb'dac) and Distal-less (Gb'Dll). We found that depletion of Gb'Dll mRNA results in loss of the tarsal segments, while rdRNAi against Gb'dac shortens the tibia at the two most distal tarsomeres. These results indicate that Gb'Dll expression is indispensable for formation of the tarsus, while Gb'dac expression is necessary for elongation of the tibia and formation of the most proximal tarsomere. These findings demonstrate that mutual transcriptional regulation between the two is indispensable for formation of the tarsomeres, whereas Gb'dac is involved in determination of tibial size through interaction with Gb'ds/Gb'ft.

Analysis of RNA-Seq data reveals involvement of JAK/STAT signalling during leg regeneration in the cricket Gryllus bimaculatus,
Development, Vol.140, No.5, 959-964, 2013.

(要約): In the cricket Gryllus bimaculatus, missing distal parts of the amputated leg are regenerated from the blastema, a population of dedifferentiated proliferating cells that forms at the distal tip of the leg stump. To identify molecules involved in blastema formation, comparative transcriptome analysis was performed between regenerating and normal unamputated legs. Components of JAK/STAT signalling were upregulated more than twofold in regenerating legs. To verify their involvement, Gryllus homologues of the interleukin receptor Domeless (Gb'dome), the Janus kinase Hopscotch (Gb'hop) and the transcription factor STAT (Gb'Stat) were cloned, and RNAi was performed against these genes. Gb'dome(RNAi), Gb'hop(RNAi) and Gb'Stat(RNAi) crickets showed defects in leg regeneration. Blastema expression of Gb'cyclinE was decreased in the Gb'Stat(RNAi) cricket compared with that in the control. Hyperproliferation of blastema cells caused by Gb'fat(RNAi) or Gb'warts(RNAi) was suppressed by RNAi against Gb'Stat. The results suggest that JAK/STAT signalling regulates blastema cell proliferation during leg regeneration.

Mechanism of asymmetric ovarian development in chick embryos.,
Development, Vol.135, No.4, 677-685, 2008.

(要約): In most animals, the gonads develop symmetrically, but most birds develop only a left ovary. A possible role for estrogen in this asymmetric ovarian development has been proposed in the chick, but the mechanism underlying this process is largely unknown. Here, we identify the molecular mechanism responsible for this ovarian asymmetry. Asymmetric PITX2 expression in the left presumptive gonad leads to the asymmetric expression of the retinoic-acid (RA)-synthesizing enzyme, RALDH2, in the right presumptive gonad. Subsequently, RA suppresses expression of the nuclear receptors Ad4BP/SF-1 and estrogen receptor alpha in the right ovarian primordium. Ad4BP/SF-1 expressed in the left ovarian primordium asymmetrically upregulates cyclin D1 to stimulate cell proliferation. These data suggest that early asymmetric expression of PITX2 leads to asymmetric ovarian development through up- or downregulation of RALDH2, Ad4BP/SF-1, estrogen receptor alpha and cyclin D1.

Mesonephric FGF signaling is associated with the development of sexually indifferent gonadal primordium in chick embryos.,
Developmental Biology, Vol.280, No.1, 150-161, 2005.

(要約): The gonad as well as the reproductive tracts, kidney, and adrenal cortex are derived from the intermediate mesoderm. In addition, the intermediate mesoderm forms the mesonephros. Although the mesonephros is the source of certain testicular cell types, its contribution to gonad formation through expression of growth factors is largely unknown. Here, we examined the expression profiles of FGF9 in the developing mesonephros of chick embryos at sexually indifferent stages, and found that the expression domain is adjacent to the gonadal primordium. Moreover, FGFR3 (FGF receptor 3) showed a strong expression in the gonadal primordium. Next, we examined the functions of FGF signal during gonadal development with misexpressed FGF9. Interestingly, misexpression of FGF9 led to gonadal expansion through stimulation of cell proliferation. In contrast, treatment with a chemical inhibitor for FGFR decreased cell proliferation and resulted in reduction of the gonadal size. Simultaneously, the treatment resulted in reduction of gonadal marker gene expression. Our study demonstrated that FGF expressed in the developing mesonephros is involved in the development of the gonad at the sexually indifferent stages through stimulation of gonadal cell proliferation and gonadal marker gene expression.

Asymmetric expression of antivin/lefty1 in the early chick embryo,
Mechanisms of Development, Vol.90, No.1, 115-118, 2000.

(要約): Mammalian lefty and zebrafish antivin, highly related to lefty, are shown to be expressed asymmetrically and involved in the specification of the left body side of early embryos. We isolated a chick homologue of the antivin/lefty1 cDNA and studied its expression pattern during early chick development. We found that antivin/lefty1 is expressed asymmetrically on the left side of the prospective floorplate, notochord and lateral plate mesoderm of the chick embryo.

Pitx2, a bicoid-type homeobox gene, is involved in a lefty-signaling pathway in determination of left-right asymmetry,
Cell, Vol.94, No.3, 299-305, 1998.

(要約): Signaling molecules such as Activin, Sonic hedgehog, Nodal, Lefty, and Vg1 have been found to be involved in determination of left-right (L-R) asymmetry in the chick, mouse, or frog. However, a common signaling pathway has not yet been identified in vertebrates. We report that Pitx2, a bicoid-type homeobox gene expressed asymmetrically in the left lateral plate mesoderm, may be involved in determination of L-R asymmetry in both mouse and chick. Since Pitx2 appears to be downstream of lefty-1 in the mouse pathway, we examined whether mouse Lefty proteins could affect the expression of Pitx2 in the chick. Our results indicate that a common pathway from lefty-1 to Pitx2 likely exists for determination of L-R asymmetry in vertebrates.

Correlation of wing-leg identity in ectopic FGF-induced chimeric limbs with the differential expression of chick Tbx5 and Tbx4.,
Development, Vol.125, No.1, 51-60, 1998.

(要約): It has been reported that members of the fibroblast growth factor (FGF) family can induce additional limb formation in the flank of chick embryos. The phenotype of the ectopic limb depends on the somite level at which it forms: limbs in the anterior flank resemble wings, whereas those in the posterior flank resemble legs. Ectopic limbs located in the mid-flank appear chimeric, possessing characteristics of both wings and legs; feather buds are present in the anterior halves with scales and claws in the posterior halves. To study the mechanisms underlying the chimerism of these additional limbs, we cloned chick Tbx5 and Tbx4 to use as forelimb and hindlimb markers and examined their expression patterns in FGF-induced limb buds. We found that Tbx5 and Tbx4 were differentially expressed in the anterior and posterior halves of additional limb buds in the mid-flank, respectively, consistent with the chimeric patterns of the integument. A boundary of Tbx5/Tbx4 exists in all ectopic limbs, indicating that the additional limbs are essentially chimeric, although the degree of chimerism is dependent on the position. The boundary of Tbx5/Tbx4 expression is not fixed at a specific position within the interlimb region, but dependent upon where FGF was applied. Since the ectopic expression patterns of Tbx5/Tbx4 in the additional limbs are closely correlated with the patterns of their chimeric phenotypes, it is likely that Tbx5 and Tbx4 expression in the limb bud is involved in determination of the forelimb and hindlimb identities, respectively, in vertebrates.

The mesenchymal factor, FGF10, initiates and maintains the outgrowth of the chick limb bud through interaction with FGF8, an apical ectodermal factor,
Development, Vol.124, No.11, 2235-2244, 1997.

(要約): Vertebrate limb formation has been known to be initiated by a factor(s) secreted from the lateral plate mesoderm. In this report, we provide evidence that a member of the fibroblast growth factor (FGF) family, FGF10, emanates from the prospective limb mesoderm to serve as an endogenous initiator for limb bud formation. Fgf10 expression in the prospective limb mesenchyme precedes Fgf8 expression in the nascent apical ectoderm. Ectopic application of FGF10 to the chick embryonic flank can induce Fgf8 expression in the adjacent ectoderm, resulting in the formation of an additional complete limb. Expression of Fgf10 persists in the mesenchyme of the established limb bud and appears to interact with Fgf8 in the apical ectoderm and Sonic hedgehog in the zone of polarizing activity. These results suggest that FGF10 is a key mesenchymal factor involved in the initial budding as well as the continuous outgrowth of vertebrate limbs.

Cricket: The third domesticated insect.,
Current Topics in Developmental Biology, Vol.147, 291-306, Mar. 2022.

(要約): Many researchers are using crickets to conduct research on various topics related to development and regeneration in addition to brain function, behavior, and biological clocks, using advanced functional and perturbational technologies such as genome editing. Recently, crickets have also been attracting attention as a food source for the next generation of humans. In addition, crickets are increasingly being used as disease models and biological factories for pharmaceuticals. Cricket research has thus evolved over the last century from use primarily in highly important basic research, to use in a variety of applications and practical uses. These insects are now a state-of-the-art model animal that can be obtained and maintained in large quantities at low cost. We therefore suggest that crickets are useful as a third domesticated insect for scientific research, after honeybees and silkworms, contributing to the achievement of global sustainable development goals.

Molecular mechanisms of limb regeneration: insights from regenerating legs of the cricket Gryllus bimaculatus,
The International Journal of Developmental Biology, Vol.62, No.6-7-8, 559-569, Jun. 2018.

(要約): This review summarizes recent advances in leg regeneration research, focusing on the cricket Gryllus bimaculatus. Recent studies have revealed molecular mechanisms on blastema formation, establishment of positional information, and epigenetic regulation during leg regeneration. Especially, these studies have provided molecular bases in classical conceptual models such as the polar coordinate model, the intercalation model, the boundary model, the steepness model, etc., which were proposed to interpret regeneration processes of the cockroach legs. When a leg is amputated, a blastema is formed through the activation of the Janus-kinase (Jak)/Signal-Transduction-and-Activator-of-Transcription (STAT) pathway. Subsequently, the Hedgehog/Wingless/Decapentaplegic/Epidermal-growth-factor pathways instruct distalization in the blastema, designated as the molecular boundary model. Downstream targets of this pathway are transcription factors Distal-less (Dll) and dachshund (dac), functioning as key regulators of proximodistal pattern formation. Dll and dac specify the distal and proximal regions in the blastema, respectively, through the regulation of tarsal patterning genes. The expression of leg patterning genes during regeneration may be epigenetically controlled by histone H3K27 methylation via Enhancer-of-zeste and Ubiquitously-transcribed-tetratricopeptide-repeat-gene-X-chromosome. For the molecular mechanism of intercalation of the missing structures between the amputated position and the most distal one, Dachsous/Fat (Ds/Ft) steepness model has been proposed, in which the Ds/Ft pathway maintains positional information and determines leg size through dac expression. This model was theoretically verified to interpret the experimental results obtained with cricket legs. Availability of whole-genome sequence information, regeneration-dependent RNA interference, and genome editing technique will have the cricket be an ideal model system to reveal gene functions in leg regeneration.
