Nobuhiro Nakao,Hiroko Ono,Takashi Yamamura,Tsubasa Anraku,Tsuyoshi Takagi,Kumiko Higashi,Shinobu Yasuo,Yasuhiro Katou,Saburo Kageyama,Yumiko Uno,Takeya Kasukawa,Masayuki Iigo,Peter J. Sharp,Atsushi Iwasawa,Yutaka Suzuki,Sumio Sugano,Teruyuki Niimi,Makoto Mizutani,Takao Namikawa,Shizufumi Ebihara,Hiroki R. Ueda,Takashi Yoshimura +21 more
TL;DR: Two waves of gene expression are identified in the quail MBH associated with the initiation of photoinduced secretion of luteinizing hormone and increased TSH in the pars tuberalis seems to trigger long-day photoinduced seasonal breeding.
Journal ArticleDOI
Photoperiodic regulation of type 2 deiodinase gene in Djungarian hamster: possible homologies between avian and mammalian photoperiodic regulation of reproduction.
Miwa Watanabe,Shinobu Yasuo,Tsuyoshi Watanabe,Takashi Yamamura,Nobuhiro Nakao,Shizufumi Ebihara,Takashi Yoshimura +6 more
TL;DR: It was found that expression of Dio2 in the mediobasal hypothalamus is induced by light and that T(3) content in the mediated hypothalamus increased under long day conditions and intracerebroventricular infusion of T( 3) mimics photoperiodically induced testicular growth.
Journal ArticleDOI
The reciprocal switching of two thyroid hormone-activating and -inactivating enzyme genes is involved in the photoperiodic gonadal response of Japanese quail.

TL;DR: These reciprocal changes in the two gene switches are the earliest events yet recorded in the photoinduction process, and overall, these reciprocal changes offer the potential to regulate active brain thyroid hormone concentrations rather precisely at the site in the brain wherephotoinduction is triggered.
Journal ArticleDOI
Circadian Clock Gene Regulation of Steroidogenic Acute Regulatory Protein Gene Expression in Preovulatory Ovarian Follicles
Nobuhiro Nakao,Shinobu Yasuo,Atsuko Nishimura,Takashi Yamamura,Tsuyoshi Watanabe,Tsubasa Anraku,Toshiyuki Okano,Yoshitaka Fukada,Peter J. Sharp,Shizufumi Ebihara,Takashi Yoshimura +10 more
TL;DR: The expression of the clock genes, Per2 and Per3, Clock, and Bmal1 (brain and muscle Arnt-like protein 1), in preovulatory follicles in laying quail are demonstrated by demonstrating the timing of ovulation in poultry is controlled solely by a clock-dependent mechanism within the neuroendocrine system.
Journal ArticleDOI
Thyroid hormones and seasonal reproductive neuroendocrine interactions
TL;DR: This review aims to summarize the currently available knowledge on the interactions between elements of the thyroid hormone axis and the neuroendocrine system involved in seasonal reproduction.
