MiR-501-3p has been reported to play an important role in several types of tumors, including prostate cancer and hepatocellular carcinoma. However, the biological function and potential mechanism of miR-501-3p in OS have not been well investigated until now. Here, we analyzed the expression of miR-501-3p in OS tissues and cell lines and its clinical significance in OS patients. Quantitative reverse transcription PCR showed miR-501-3p was significantly up-regulated in OS tissues and cell lines. Up-regulated miR-501-3p expression was associated with TNM stage, distal metastasis and worse prognosis in OS patients. MiR-501-3p knockdown and overexpression were achieved by miR-501-3p inhibitor and mimics transfection, respectively. CCK-8, colony formation and transwell assays showed that miR-501-3p knockdown in U2OS and Saos-2 cells supp ressed, while miR-501-3p overexpression in Saos-2 cells promoted cell proliferation, migration and invasion. Moreover, luciferase reporter assay supporting BCL7A was a target of miR-501-3p and its expression was increased by miR-501-3p inhibitor, but inhibited by miR-501-3p mimics. By performing rescue experiments, we further demonstrated that BCL7A was a downstream functional regulator involved in miR-501-3p promoting OS cell functions. In summary, our findings suggest that miR-501-3p targets BCL7A may provide novel therapeutic targets for the treatment of OS. View on the web Inoreader. Take back control of your news feed.
