Sumario:The aim of the present study was to investigate the potential anticancer effects of microRNA-216a on the growth of human breast cancer and the possible underlying mechanisms. The results demonstrated that serum microRNA-216a was significantly decreased in patients with breast cancer compared with healthy controls. MicroRNA-216a overexpression led to a decrease in cell proliferation and migration, as well as increases in apoptosis, caspase-3/8 activities, Bax expression and p53 protein expression in MCF-7 cells. It was also revealed that microRNA-216a suppressed Wnt and β-catenin expression in MCF-7 cells. The anticancer effects of microRNA-216a were reversed by anti-microRNA-216a by promoting the Wnt/β-catenin signaling pathway. Inactivation of the Wnt pathway increased the anticancer effects of microRNA-216a in MCF-7 cells. Collectively, the results of the present study indicated that microRNA-216a suppressed the growth of human breast cancer cells by targeting the Wnt/β-catenin signaling pathway.
