Through selective activation of the gonadotropic signal transduction pathway, we have determined the probable site of the antigonadotropic effects of prostaglandin F2alpha (PGF2alpha) in the human granulosa-luteal cell (hGLC). The gonadotropic signal transduction pathway was activated at the level of the receptor (luteinizing hormone and beta-adrenergic),(More)
This study examined the effects of prostaglandin F2alpha (PGF2alpha) and human chorionic gonadotropin (hCG) on the levels of PGF2alpha-receptor (PGF2alpha-R) mRNA and steroidogenesis, in the human granulosa luteal cell (hGLC). Human GLCs collected from patients undergoing in vitro fertilization, were cultured for 24 h, after which cells were exposed to(More)
This study examined the effects of prostaglandin-F(2alpha) (PGF(2alpha)), prostaglandin-E(2) (PGE(2)) and their interactions on progesterone production in human granulosa-luteal cells (GLCs). Human GLCs collected from in vitro fertilization patients were cultured for 1 (D(1)) or 8 days (D(8)), followed by a 24-hour treatment period, after which media were(More)
