Quantitative data of the wound-healing assay showing the migration of ME180 cells that were treated with control (siCTRL) or YAP siRNA (siYAP) prior to treatment with or without TGF-α for 12 h. Each bar in bar graphs represents the mean ± SEM (n = 4). Bars with different letters are significantly different from each other (siCtrl vs. siCTRL+TGF-α, P < 0.0001; siYAP+CTRL vs. siYAP+TGF-α, P < 0.0001; siCTRL+TGF-α vs. siYAP+TGF-α, P = 0.0041).
