Role of miR-145-5p Targeting ARK5 in Regulating the Proliferation and Apoptosis of Human Epithelial Ovarian Cancer Cells / 中国医学科学院学报

ABSTRACT

Objective To explore the effect of miR-145-5p on the proliferation and apoptosis of human ovarian cancer cells and the possible molecular mechanisms involved.Methods Real-time quantitative PCR was performed to detect the expression of miR-145-5p in ovarian epithelial cells and ovarian cancer cells.CCK-8 and flow cytometry were used to detect the effects of miR-145-5p overexpression on the proliferation and apoptosis of ovarian cancer cells.TargetScan was employed to predict the target genes of miR-145-5p.Western blotting,dual luciferase reporter assay and rescue experiment were employed to predict and verify the underlying molecular mechanism of miR-145-5p function.Results The expression of miR-145-5p in ovarian cancer cells was significantly lower than that in normal ovarian epithelial cells(
