摘要:

活性氧(reactive oxygen species,ROS)在生理状态下作为第二信使发挥细胞信号转导作用,当机体受到缺氧、炎症反应等刺激时,体内ROS水平增加,诱导体内发生氧化应激(oxidative stress)反应。适量的ROS促进卵母细胞的第一次减数分裂,并诱导非优势卵泡进入细胞凋亡。研究表明,氧化应激与多囊卵巢综合征(polycystic ovary syndrome,PCOS)患者的高雄激素血症、胰岛素抵抗、排卵障碍和线粒体损伤等有密切联系;应用抗氧化剂控制氧化应激可能成为早发性卵巢功能不全(premature ovarian insufficiency,POI)的辅助治疗方式。氧化应激抑制DNA甲基化酶引起DNA低甲基化、引起微小RNA及相关活性因子的表达异常,参与卵巢肿瘤细胞增殖和耐药性发生。综述氧化应激在PCOS、POI和卵巢肿瘤等卵巢相关生殖障碍疾病中的作用,展望抗氧化应激治疗的可能应用前景。

Abstract:

Reactive oxygen species(ROS) at the physiological level may play a role of the second messengers in signal transduction. When the body is stimulated by hypoxia, inflammatory response and others, the increased significantly level of ROS induces oxidative stress. ROS at an appropriate level promotes the first meiosis of oocytes, and induces the apoptosis of non-dominant follicles. Studies have shown that oxidative stress is closely related to hyperandrogenemia, insulin resistance, ovulation disorders and mitochondrial damage in the patients with polycystic ovary syndrome (PCOS). Controlling oxidative stress with antioxidants may be an adjunct therapy for the premature ovarian insufficiency(POI). Oxidative stress inhibits DNA methylase, which leads to DNA hypomethylation, and the abnormal expressions of microRNA and the factors related to the proliferation of ovarian cancer cells and the drug resistance. This article reviews the role of oxidative stress in ovary-related reproductive disorders such as PCOS, POI and ovarian tumors, and looks forward to the possible application of antioxidant therapy.
