摘要: 颗粒细胞受黄体生成激素(LH)刺激后分泌的前列腺素E2(PGE2),通过旁分泌和自分泌,结合卵丘细胞上的前列腺素受体2,进而激活腺苷酸环化酶,增加胞内cAMP含量并促进透明质酸合酶2和肿瘤坏死因子α介导蛋白6的合成,引起卵丘细胞扩展。PGE2还通过调控颗粒细胞类固醇代谢通路影响孕酮分泌,从而调节黄体的功能。本文就PGE2在卵泡发育的作用进行综述。

Abstract: Luteinizing hormone (LH) increases granulosa cell secretion of prostaglandin E2(PGE2).And by paracrine and autocrine signals, PGE2 acts at cumulus cells’ prostaglandin receptor 2 (PTGER2) ,activates the adenylate cyclase (AC),and increases intracellular (cyclic adenosine monophosphate) cAMP content and the synthesis of hyaluronan synthase 2 (HAS2) and tumor necrosis factor alpha mediated protein 6.Finally it would promote cumulus cells expansion. PGE2 also regulates the steroid metabolism pathway of granular cells and impacts the secretion of progesterone, and regulates the function of corpus. This paper describes the mechanism and function of PGE2 in the process of follicular development.

Key words: follicular development, ovulation, cumulus cells, Prostaglandin E2, Prostaglandin receptors
