Long non-coding RNAs (lncRNAs) play a vital role in the progression of many human diseases. The aim of this study is to explore the relationship between lncRNA-ovarian cancer associated 1 (Lnc-OC1) and PCOS. In this study, we found that Lnc-OC1 was significantly higher in PCOS granulosa cells (GCs) compared to non-PCOS GCs. Lnc-OC1 knockdown inhibited cell viability and promoted cell apoptosis, expression of aromatase mRNA and production of estradiol in KGN cells. In PCOS mice, Lnc-OC1 promoted the serum insulin release, production of angiogenesis-related factors and IκBα phosphorylation, which could be partially restored by Lnc-OC1 shRNA. These results suggest that Lnc-OC1 plays an important part in the pathogenesis of PCOS.
长链非编码 RNA（lncRNAs）在许多人类疾病的进展中起着至关重要的作用。本研究旨在探讨 lncRNA-卵巢癌相关 1（Lnc-OC1）与 PCOS 之间的关系。在这项研究中，我们发现 PCOS 颗粒细胞（GCs）中的 Lnc-OC1 明显高于非 PCOS GCs。Lnc-OC1 敲低抑制了 KGN 细胞的活力并促进了细胞凋亡、芳香化酶 mRNA 的表达和雌二醇的产生。在 PCOS 小鼠中，Lnc-OC1 促进了血清胰岛素的释放、血管生成相关因子的产生和 IκBα 的磷酸化，而这些作用可以部分被 Lnc-OC1 shRNA 所恢复。这些结果表明 Lnc-OC1 在 PCOS 的发病机制中起着重要作用。
