NPGL and NPGM play important roles in lipid metabolism in juvenile chickens. The physiological functions of NPGL and NPGM in sexually mature birds remain unknown. The Japanese quail (Coturnix japonica) seems to be an appropriate model for analyzing NPGL and NPGM during sexual maturity. However, studies on NPGL or NPGM have yet to be reported in the Japanese quail. In the present study, we identified cDNAs encoding precursor proteins of NPGL and NPGM in the quail hypothalamus. In situ hybridization revealed that NPGL mRNA-expressing cells in the hypothalamus were localized in the infundibular nucleus and median eminence, and NPGM mRNA-expressing cells were only found in the mammillary nucleus. Immunohistochemistry revealed that NPGM-like immunoreactive cells were distributed in the mammillary nucleus, whereas NPGL-like immunoreactive cells were not detected in the hypothalamus. Real-time PCR analysis indicated that the expression of NPGL mRNA was higher in the hypothalamus of females than in that of males, and NPGM mRNA expression showed no sex differences. NPGL and NPGM mRNA expression in males was upregulated after 24 h of food deprivation. In females, only NPGM mRNA expression was increased by fasting. These results suggest that the physiological functions of NPGL and NPGM are different in quail, and these factors are involved in sex differences in energy metabolism.","PeriodicalId":24040,"journal":{"name":"Zoological Science","volume":"41 1","pages":"50-59"},"PeriodicalIF":0.9,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140867545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Secreted hormones play significant roles in lifetime-related events such as germ cell development, sexual maturation, development, metamorphosis, aging, feeding, and energy metabolism. Additionally, hormones, particularly sex steroid hormones, are involved in reproduction, including sexual behavior and dimorphism. Changes in body color protect against external enemies, and circadian rhythms direct physiology and behaviors in synchrony with light and dark cycles. Water and electrolyte metabolism are essential for survival in land or seawater. Both aquatic and terrestrial animals have developed a variety of endocrine and neuroendocrine systems that exquisitely manage water and electrolyte metabolism to support survival. In zoological science, many animal species are investigated for their unique life history phenomena, and many researchers bring original and unique research approaches to understand these phenomena. Exploring such a variety of animal species leads to an understanding of diversity and unity, and contributes to the development of comparative endocrinology. This Special Issue contains 15 papers focusing on the endocrine mechanisms involved in the aforementioned life phenomena.","PeriodicalId":24040,"journal":{"name":"Zoological Science","volume":"41 1","pages":"1-3"},"PeriodicalIF":0.9,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140872400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that ommin, an ommochrome purified from the diapause eggs of Bombyx mori, inhibited the RT-PCR and restriction enzyme activities. The mechanism of these inhibitory reactions is assumed to be the direct binding of ommochrome to DNA rather than acting against the enzymes because, similarly to actinomycin D, there is a phenoxazine ring in the structure of ommin that is known to be intercalated to DNA. To reveal the ommin/DNA interaction, it was investigated by computational approaches such as molecular docking, molecular dynamics simulation, and free energy calculation. From the computational analyses, it was expected that ommin would bind to DNA with almost the same strength as actinomycin D and intercalate into DNA. This is the first report on the pharmacological effect of ommochrome and its inhibitory mechanism obtained from biochemical and computational analyses.","PeriodicalId":24040,"journal":{"name":"Zoological Science","volume":"40 6","pages":"431-436"},"PeriodicalIF":0.9,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138809987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Japanese stream toad, Bufo torrenticola, breeds in running water, such as mountain streams, where the larvae grow. This lotic-breeding habit of B. torrenticola was suggested to have evolved from a lentic-breeding ancestor. Evolutionary shift of breeding habit from lentic- to lotic-breeding caused larval morphological changes to adapt to the stream habitat. However, morphological adaptation associated with the larval habitat of these three types of Japanese toads has not been explored well. In this study, we applied geometric morphometrics and distance measurements to compare body and eye characters among the tadpoles of three Japanese toads. The results showed that B. torrenticola has more dorsally and posteriorly positioned eyes, and a longer and wider rostrum because of having a larger mouth and more-developed oral muscles than its close relatives. These characters might be related to lotic lifestyle. Meanwhile, tadpoles of B. torrenticola and its sister taxon B. japonicus japonicus showed similar eye growth pattern, supporting their close phylogenetic relationship. Some of the lotic-adapted characters have also been reported in other lotic tadpoles, which is indicative of convergent evolution among stream-adapted tadpoles.","PeriodicalId":24040,"journal":{"name":"Zoological Science","volume":"40 6","pages":"468-474"},"PeriodicalIF":0.9,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138809931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This genus is distinguished from other genera of the subfamily Parancistrolepidinae with a combination of shell traits, including (1) a low spire, (2) sharp, carinate spiral cords or keels and (3) a long, curved siphonal canal, but not with a difference in radular morphology as suggested by previous authors. Three allopatric or parapatric species are recognized in the upper bathyal (447-2057 m) waters around Japan and Taiwan: B. tokoyodaensis from off Hokkaido to Sagami Bay in the Northwest Pacific, B. trochoidea off Kumano-nada to Miyazaki in the Northwest Pacific and along Nansei Islands in the East China Sea, and B. taiwanensis sp. nov. in the South China Sea. These species bear large paucispiral protoconchs that are indicative of benthic early development without a pelagic larval period, and hence low dispersal capability. Seafloor topography seems to have acted as a barrier for their dispersal; the range of B. tokoyodaensis supports the previous finding that Izu Peninsula delimits westward distribution of bathyal gastropod species of boreal origins.","PeriodicalId":24040,"journal":{"name":"Zoological Science","volume":"40 6","pages":"486-496"},"PeriodicalIF":0.9,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138810033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
