摘要: FoxO1 is a transcription factor implicated in a multitude of physiological processes including cell cycle progression, apoptosis and insulin signaling. Recent findings indicate that FoxO1 is a key regulator during the proliferation and maturation of granulosa cells. Over the past several years, it has become evident that nitric oxide (NO) and cGMP modulate ovarian function. There has been no information, however, about whether NO-cGMP affects FoxO1 expression or about the relationship between NO-cGMP and FoxO1. In the present study, we used immunoblot analysis to determine whether NO and cGMP affect FoxO1 expression in cultured granulosa cells. Our results clearly showed that FSH suppressed FoxO1 expression in a time-dependent manner, and that NO-cGMP stimulated FoxO1 expression in cultured granulosa cells. In addition, this stimulatory effects of NO and cGMP can be blocked by FSH in cultured granulosa cells. These findings demonstrate that NO and cGMP influence FoxO1 expression possibly through antagonizing the action of FSH in cultured granulosa cells. Results of both immunoblot analysis and immunohistochemistry also show that estradiol implantation do not affect the expression of FoxO1 in rat granulosa cells as gonadotrophins do, indicating that mechanism of estradiol on granulosa cells is different from gonaclotrophins. Together, our experiments suggest that expression of FoxO1 in rat granulosa cells can be regulated by gonadotrophins and the NO/cGMP signaling pathway.
