Prostate cancer has become one of commonest urologic tumors in male. In recent years, miRNAs are continually attracting attentions of researchers for their special regulatory function in human cancers. Previous study has revealed that miR-410 acts as a biomarker for the diagnosis of prostate cancer. Whereas, the specific biological function of miR-410–3p in prostate cancer remains unknown. The aim of this study is to explore the function and molecular mechanism of miR-410–3p in prostate cancer. The high expression of miR-410–3p was examined in prostate cancer tissues and cell lines by qRT-PCR. Next, the prognostic value was identified by Kaplan Meier method. High expression of miR-410–3p indicated poor prognosis of prostate cancer patients. To investigate the biological function of miR-410–3p in prostate cancer, loss-of function assays were designed and performed in two prostate cancer cell lines (PC3 and DU145). As a result, downregulated miR-410–3p suppressed cell proliferation, migration and EMT progress. Moreover, flow cytometry analysis was performed to determine that the acceleration effects of miR-410–3p on cell apoptosis. Mechanistically, further analysis demonstrated that the effects of miR-410–3p exert oncogenic functions through downregulating PTEN. All findings in this study revealed that miR-410–3p inhibits prostate cancer progression via downregulating PTEN/AKT/mTOR signaling pathway.
