WebFSH acts on the gamete-producing cells to regulate gametogenesis. LH acts on the endocrine or hormone-producing cells, stimulating release of steroid sex hormones. There are two levels of feedback control over production of steroid sex hormones. Gonadal hormones secreted into the body circulation eventually reach the brain and pituitary and ...
WebThe effects of IGF-I on expression of genes encoding glycoprotein alpha (GPalpha), follicle-stimulating hormone (FSH) beta, and luteinizing hormone (LH) beta subunits and release of FSH and LH were examined using primary pituitary cells of masu salmon at three reproductive stages: early gametogenesis, maturing stage, and spawning. WebThe glycoprotein follicle-stimulating hormone (FSH) acts on gonadal target cells, hence regulating gametogenesis. The transduction of the hormone-induced signal is mediated by the FSH-specific G protein-coupled …
