多囊卵巢综合征(PCOS)是一种类固醇激素产生和活性改变的状态。长期雌激素暴露或由于卵巢功能障碍而缺乏孕激素可导致子宫内膜增生和癌。一个关键的贡献者,我们了解孕激素作为一个重要的调节正常子宫功能的孕激素受体(PR)的表达,调节和信号通路的阐明。几项人体研究表明,细胞核中PR介导的信号通路与PCOS妇女的孕酮抵抗有关。本文综述了PCOS患者子宫内膜孕酮抵抗的研究进展,介绍了孕激素受体的结构、亚型及其在子宫内膜中的表达,阐明了孕激素受体及其介导的信号通路在PCOS患者孕酮抵抗中的可能调控作用,并对孕激素受体的功能进行了初步探讨。并讨论目前临床治疗不典型子宫内膜增生和子宫内膜癌的妇女多囊卵巢综合征和伴随孕激素抵抗。
Polycystic ovary syndrome (PCOS) is a state of altered steroid hormone production and activity. Chronic estrogen exposure or lack of progesterone due to ovarian dysfunction can result in endometrial hyperplasia and carcinoma. A key contributor to our understanding of progesterone as a critical regulator for normal uterine function has been the elucidation of progesterone receptor (PR) expression, regulation, and signaling pathways. Several human studies indicate that PR-mediated signaling pathways in the nucleus are associated with progesterone resistance in women with PCOS. The aim of this review is to provide an overview of endometrial progesterone resistance in women with PCOS; to present the PR structure, its different isoforms, and their expression in the endometrium; to illustrate the possible regulation of PR and PR-mediated signaling in progesterone resistance in women with PCOS; and to discuss current clinical treatments for atypical endometrial hyperplasia and endometrial carcinoma in women with PCOS and accompanying progesterone resistance.
