多囊卵巢综合征(PCOS)是最常见的女性内分泌疾病,可导致无排卵性不孕,但由于其病因尚不清楚,目前仍缺乏准确诊断和有效治疗的策略。在本研究中,我们通过比较 PCOS 患者和正常个体的卵巢组织样本,确定了 circPSMC3 表达的异常降低。 PCOS 模型小鼠中 circPSMC3 上调引起的症状缓解表明了进一步研究的潜力。体外功能实验证实,circPSMC3可以通过阻断人样颗粒肿瘤细胞系的细胞周期来抑制细胞增殖并促进细胞凋亡。机制研究表明,circPSMC3可能通过海绵miR-296-3p调节PTEN表达发挥作用。总的来说,我们初步描述了 circPSMC3/miR-296-3p/PTEN 轴在 KGN 细胞增殖和凋亡中的作用和可能的见解。我们希望这项工作为circRNA在PCOS中的研究提供一些原创且有价值的信息,不仅可以更好地了解PCOS的发病机制,而且有助于为寻找PCOS未来的治疗靶点提供新的线索。
Polycystic ovary syndrome (PCOS), the most common female endocrine disease that causes anovulatory infertility, still lacks promising strategy for the accurate diagnosis and effective therapeutics of PCOS attributed to its unclear aetiology. In this study, we determined the abnormal reduction in circPSMC3 expression by comparing the ovarian tissue samples of PCOS patients and normal individuals. The symptom relief caused by up‐regulation of circPSMC3 in PCOS model mice suggested the potential for further study. In vitro functional experiments confirmed that circPSMC3 can inhibit cell proliferation and promote apoptosis by blocking the cell cycle in human‐like granular tumour cell lines. Mechanism study revealed that circPSMC3 may play its role through sponging miR‐296‐3p to regulate PTEN expression. Collectively, we preliminarily characterized the role and possible insights of circPSMC3/miR‐296‐3p/PTEN axis in the proliferation and apoptosis of KGN cells. We hope that this work provides some original and valuable information for the research of circRNAs in PCOS, not only to better understand the pathogenesis but also to help provide new clues for seeking for the future therapeutic target of PCOS.
