Journal ArticleDOI
Thyrotrophin in the pars tuberalis triggers photoperiodic response
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
Light-induced hormone conversion of T4 to T3 regulates photoperiodic response of gonads in birds.
Takashi Yoshimura,Shinobu Yasuo,Miwa Watanabe,Masayuki Iigo,Takashi Yamamura,Kanjun Hirunagi,Shizufumi Ebihara +6 more
TL;DR: It is demonstrated that light-induced Dio2 expression in the MBH may be involved in the photoperiodic response of gonads in Japanese quail.
Journal ArticleDOI
A mammalian neural tissue opsin (Opsin 5) is a deep brain photoreceptor in birds
Yusuke Nakane,Keisuke Ikegami,Hiroko Ono,Naoyuki Yamamoto,Shosei Yoshida,Kanjun Hirunagi,Shizufumi Ebihara,Yoshihiro Kubo,Takashi Yoshimura +8 more
TL;DR: It is found that short-wavelength light, i.e., between UV-B and blue light, induced photoperiodic responses in eye-patched, pinealectomized quail, and Opsin 5 appears to be one of the deep brain photoreceptive molecules that regulates seasonal reproduction in birds.
Journal ArticleDOI
Involvement of thyrotropin in photoperiodic signal transduction in mice
Hiroko Ono,Yuta Hoshino,Shinobu Yasuo,Shinobu Yasuo,Miwa Watanabe,Yusuke Nakane,Atsushi Murai,Shizufumi Ebihara,Horst-Werner Korf,Takashi Yoshimura +9 more
TL;DR: Melatonin-dependent regulation of thyroid hormone levels in the MBH appears to involve TSH in mammals, and it is shown that melatonin administration did not affect the expression of TSHB, DIO2, and DIO3 in TSHR-null mice.
Journal ArticleDOI
Molecular analysis of avian circadian clock genes
Takashi Yoshimura,Yoshikazu Suzuki,Eri Makino,Tomohiro Suzuki,Asato Kuroiwa,Yoichi Matsuda,Takao Namikawa,Shizufumi Ebihara +7 more
TL;DR: Cloned Clock and Period homologs (qClock, qPer2 and qPer3) are cloned and characterized and can explain the molecular basis for circadian entrainment in Japanese quail and provide new avenues for molecular understanding of avian circadian clock and photoperiodism.
