TL;DR: It is shown that KiSS-1 encodes a carboxy-terminally amidated peptide with 54 amino-acid residues, which is isolated from human placenta as the endogenous ligand of an orphan G-protein-coupled receptor (hOT7T175) and named ‘metastin’.
Journal ArticleDOI
Biological roles of angiotensin II via its type 2 receptor during rat follicle atresia
Eri Kotani,Masataka Sugimoto,Hachiroh Kamata,Nobuharu L. Fujii,Masahiro Saitoh,Satoshi Usuki,Takeshi Kubo,Keifu Song,Mizuo Miyazaki,Kazuo Murakami,Hitoshi Miyazaki +10 more
TL;DR: It is suggested that AT2 mediates the progression of follicle atresia through granulosa cell apoptosis by inhibiting FSH actions.
Journal ArticleDOI
The Improvement of Luteal Insufficiency in Fecund Women by Tokishakuyakusan Treatment
TL;DR: It is suggested that tokishakuyakusan improves luteal insufficiency in women but does not affect the hormonal levels of women with normal menstrual cycles.
Journal ArticleDOI
Serum testosterone responses to continuous and intermittent exercise training in male rats.
TL;DR: Serum testosterone and serum LH were investigated at rest and following exercise during 6 weeks of continuous and intermittent swimming training in male rats, and the regulatory mechanisms of the changes were discussed by evaluating serum luteinizing hormone (LH), and conducting GnRH or hCG challenge tests.
Journal ArticleDOI
Tokishakuyakusan directly attenuates PACAP's luteolytic action on luteal function in the rat ovary.

TL;DR: It is demonstrated that TS stimulates progesterone production in rat luteal cells, reconfirming the previous evidence that TS stimulate luteAL steroidogenesis and suggesting a luteotrophic effect within the corpus luteum.
