- Abstract
OBJECTIVE: Ovarian cancer is a common malignant cancer among women. Increasing studies have demonstrated that microRNAs function as important regulation factors in the progression of ovarian cancer. MATERIALS AND METHODS: Human ovarian cancer cell lines HO8910 and OVCAR-3 were transfected with miR-934 inhibitor and corresponding negative control (inhibitor control). Cell proliferation and apoptosis were detected by cell counting kit-8 (CCK-8) and TUNEL assay, respectively. The expression levels of proliferation/apoptosis-related genes and BRMS1L were measured by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) and Western blotting. Furthermore, the association between miR-934 and BRMS1L was investigated through luciferase reporter assays. RESULTS: MiR-934 was significantly increased in ovarian cancer cell lines, whereas BRMS1L was significantly decreased. Downregulated miR- 934 remarkably inhibited cell proliferation and induced cell apoptosis. Meanwhile, miR-934 could influence the expression levels of Ki67, Cyclin D1, Caspase3, and Bcl-2. In addition, BRMS1L was identified as a target gene of miR-934. CONCLUSIONS: Oncogene miR-934 promotes ovarian cancer cell proliferation and inhibits cell apoptosis through targeting BRMS1L. MiR-934 and BRMS1L may be novel biomarkers or therapeutic targets for ovarian cancer in the future.
