miR-513a-3p promotes PCa cells progression in vitro. A The migration capability of PC-3 and DU145 cells transfected with miR-513a-3p mimics or mimics NC was measured by wound healing assays. Scale bars = 100 μm. B–E The migration and invasion capabilities of PC-3 and DU145 cells transfected with miR-513a-3p mimics or mimics NC were assessed by transwell migration and invasion assays. Scale bars = 100 μm. F, G The proliferation ability of PC-3 and DU145 cells transfected with miR-513a-3p mimics or mimics NC was evaluated by CCK-8 assay. *, ** and *** represented P < 0.05, 0.01 and 0.001, respectively
