摘要: Expression of serum/glucocorticoid-inducible kinase (Sgk), one member an inducible serine/threonine family, is induced by FSH/cAMP in rat granulosa cells cultured defined medium. The FSH-stimulated pattern sgk expression biphasic, and transcriptional activation the gene depends on intact Sp1/Sp3 binding site within proximal promoter. To determine whether was expressed a hormone-dependent physiologically relevant manner vivo, cellular levels messenger RNA (mRNA) protein as well subcellular localization this were analyzed ovaries containing follicles corpora lutea at specific stages differentiation. stimulate follicular development luteinization, hypophysectomized (H) rats treated with estradiol (E; HE) FSH (FSH; HEF) followed hCG (hCG; HEF/hCG). analyze Sgk functional lutea, PRL administered to HEF/hCG rats, or pregnant obtained day 7, 15, 22 gestation....
