miR-383-5p Inhibits Human Malignant Melanoma via Targeting CENPF

Abstract Background: Human malignant melanoma (MM) is one of the skin cancers with the highest mortality. In this study, we investigated the role of miR-383-5p on human MM cells. Methods: The expression of miR-383-5p was measured by quantitative real-time PCR assay. The cell proliferation, invasion and migration were detected by CCK8, clone formation and transwell assays. Flow cytometry assay was used to detect apoptosis. The binding of miR-383-5p and 3’UTR of CENPF mRNA was indicated by dual-luciferase assays.Results: We found that miR-383-5p inhibited the cells proliferation, migration and invasion, and promoted apoptosis of M14 and A375 cells. Biochemical analysis revealed that the expression of miR-383-5p was negatively correlated with CENPF expression in human MM, and the doul-luciferase report showed that miR-383-5p could effectively bind to the 3’UTR of CENPF. CENPF expression was up-regulated and predicted the prognosis of MM. In addition, high expression of CENPF can effectively remedy the resistance of cell proliferation and vitality caused by miR-383-5p. Conclusion: In conclusion, miR-383-5p acts as a tumor suppressor in human MM by targeting CENPF, suggesting that CENPF may be a potential therapeutic target for human MM.
