Journal ArticleDOI
Progesterone is a sperm-releasing factor from the sperm-storage tubules in birds.
Tomomi Ito,Norio Yoshizaki,Toshinobu Tokumoto,Hiroko Ono,Takashi Yoshimura,Akira Tsukada,Norio Kansaku,Tomohiro Sasanami +7 more
TL;DR: Evidence is provided for the first time that the progesterone stimulates the release of the resident sperm from the SST and that therelease of the sperm might occur via membrane progestin receptor α-mediating signal transduction.
Journal ArticleDOI
cDNA cloning of chicken orexin receptor and tissue distribution: sexually dimorphic expression in chicken gonads.
TL;DR: Data indicate that the orexins have neuroendocrine actions in chickens, which are mediated through hypothalamic receptors as has been observed in mammals, and orexin may have specific role(s) in the regulation of gonadal function in which sex-dependent mechanisms could be involved.
Journal ArticleDOI
Photoinducible Phase-Specific Light Induction of Cry1 Gene in the Pars Tuberalis of Japanese Quail
Shinobu Yasuo,Miwa Watanabe,Akira Tsukada,Tsuyoshi Takagi,Masayuki Iigo,Kiyoshi Shimada,Shizufumi Ebihara,Takashi Yoshimura +7 more
TL;DR: Different phase relationships between Per2 and Cry1 in the Japanese quail PT under different photoperiods may decodePhotoperiodic information and regulate photoperperiodic PRL secretion in a manner similar to that of mammals.
Journal ArticleDOI
Effect of central administration of prolactin-releasing peptide on feeding in chicks.
Tetsuya Tachibana,Shin Saito,Shozo Tomonaga,Tomo Takagi,Ei Suke Saito,Tomonori Nakanishi,Tomoyuki Koutoku,Akira Tsukada,Takeshi Ohkubo,Timothy Boswell,Mitsuhiro Furuse +10 more
TL;DR: It is shown here that PrRP may be involved in the regulation of both feeding behavior and energy metabolism in the chick brain, which might differ from NPY-involved feeding regulatory pathway.
Journal ArticleDOI
Profiles of mRNA expression of genes related to sex differentiation of the gonads in the chicken embryo
TL;DR: Results indicate that Dax1, Sf1, and P450arom have possible roles in ovary formation, whereas Dmrt1, Sox9, and Amh are related to testis formation in differentiating chicken gonads at d 5.5 to 8.5 of incubation.
