Epithelial ovarian cancer (EOC) is the most common type of ovarian cancer, which exhibits invasive traits. MicroRNAs (miRNAs/miRs) have been demonstrated to serve important functions in the pathogenesis of EOC. However, the function of miR-545 in EOC remains unknown. In the present study, the function of miR-545 in EOC was analyzed and it was identified that miR-545 is downregulated in EOC tissues and cell lines. Additionally, a low level of miR-545 expression was associated with a low survival rate of patients with EOC. Furthermore, overexpression of miR-545 inhibited cell growth and promoted apoptosis. Suppression of miR-545 promoted cell growth and inhibited apoptosis. Additionally, the RAC-γ serine/threonine-protein kinase gene was targeted by miR-545. Thus, it may be concluded that miR-545 exhibited antitumor traits in EOC.
上皮性卵巢癌（EOC）是最常见的卵巢癌类型，具有侵袭性特征。微小RNA（miRNA/miR）已被证明在EOC的发病机制中发挥重要作用。然而，miR-545在EOC中的功能仍不清楚。在本研究中，分析了miR-545在EOC中的功能，发现miR-545在EOC组织和细胞系中表达下调。此外，miR-545低表达与EOC患者低生存率相关。此外，miR-545过表达抑制细胞生长并促进细胞凋亡。抑制miR-545则促进细胞生长并抑制细胞凋亡。此外，RAC-γ丝氨酸/苏氨酸蛋白激酶基因是miR-545的靶标。因此，可以得出结论，miR-545在EOC中表现出抗肿瘤特性。
