Overexpression of miR-655 increases cell migration and invasion ability. (a) Microscopic observations were recorded 24 hours after scratching the cell surface. The wound healing of miR-655 group was weaker than that of Blank and NC groups. (b) The number of invasive miR-655-transfected EC9706 and KYSE150 cells passing through the trans-well membrane were significantly lower than those in the Blank and NC groups (P < 0.05). Blank, non-transfected cells; NC, cells transfected with scrambled miR-655 negative control; miR-655, cells transfected with miR-655 mimics. ^*P < 0.05 compared to the control group.
