Abstract

Ovarian cancer remains as one of the most threatening malignancies for females in the world. This study investigated the pivotal role of miR-940 in the progression of ovarian cancer and to reveal the possible molecular mechanism of its action. Ovarian cancer OVCAR3 cells were transfected with the miR-940 vector, miR-940 inhibitor, and/or small interfering RNA (siRNA) targeting PKC-d (si-PKC-δ), respectively. After transfection, cell viability and cell apoptosis were analyzed, as well as cell proliferation and apoptosis-related protein expression. Compared to the control, miR-940 upregulation suppressed cell viability but induced cell apoptosis. miR- 940 upregulation increased the expression of p27, Hes1, survivin, and caspase 3, but decreased the expression of PKC-δ. In addition, elevated cell viability induced by the miR-940 inhibitor was significantly decreased by knockdown of PKC-δ, and reduced cell apoptosis induced by the miR-940 inhibitor was increased by knockdown of PKC-δ. Taken together, the results of our study suggest that upregulation of miR-940 may function as a suppressor in the progression of ovarian cancer by inhibiting cell proliferation and inducing apoptosis by targeting PKC-δ. This study may provide a basis for the possible application of miR-940 in illustrating the molecular pathogenic mechanism of ovarian cancer.
