Abstract
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.
