(A, M238P cells were transfected with miR-143-3p, miR-145-5p or a control mimic (miR-neg) (72 h, 30 nM). (B, M238P cells were treated 72 h with BRAFi (Vemurafenib, 3 µM) or a combination of BRAFi (Vemurafenib, 0.5 µM) and MEKi (Trametinib, 1 µM). (A-B) Images and quantification of cell area in cells stained for F-actin (red) and nuclei (blue). Data is represented as scatter plot with mean ± SD (n≥30 cells per condition). Mann-Whitney U test was used for statistical analysis. ****P≤0.0001. Scale bar 40 μm.
