  • Title: MicroRNA-5195-3p plays a suppressive role in cell proliferation, migration and invasion by targeting MYO6 in human non-small cell lung cancer.

    Abstract:
    MiRNA-5195-3p (miR-5195-3p), a recently discovered and poorly studied miRNA, has been reported to suppress bladder cancer cell behavior. However, its regulatory role in non-small cell lung cancer (NSCLC) remains unclear. Here, the expression of miR-5195-3p was found to be reduced in NSCLC tissues and cells. The in vitro experiments showed that miR-5195-3p upregulation repressed cell proliferation, migration and invasion by CCK-8 and transwell assays. In addition, MYO6 was predicted and confirmed as a potential target of miR-5195-3p by Bioinformatics analysis, Luciferase reporter assay and western blot analysis. There was significantly negative correlation between miR-5195-3p and MYO6 in NSCLC tissues. Furthermore, MYO6 knockdown exhibited similar effects to those of miR-5195-3p overexpression in NSCLC cells, and restored MYO6 expression reversed the inhibitory effects of miR-5195-3p. Therefore, these results demonstrate that miR-5195-3p functions as a tumor suppressor by directly modulating MYO6 expression in NSCLC cells, and may be an innovative candidate target for NSCLC therapy.
