Forced expression of miR-195 suppressed cell motility in wound healing assay without significantly affecting cell viability. a The ectopic expression of miR-195 was confirmed by qRT-PCR. Three independent experiments were performed in each group. b Cell viability assay. Overexpression of miR-195 had no apparent effect on prostate cancer cell viability (cell viability of 0 nM was regarded as 1.0, n = 3). c, d DU145 and PC3 cells were transfected with NC, miR-195 mimics at a concentration of 50 nM and were performed wound healing assays with a 24–48 h recovery period, the wound area was measured by Image J software (*P < 0.05)
