Figure 4: Clonogenic assays showing the highly superior survival of MeWo and MeWo-RhoA-V14 cells, which displayed high levels of RhoA activity, compared with RhoA-deficient MeWo-RhoA-N19 cells after exposure to different types of UV radiation. The bars represent the average and standard deviation of at least three independent experiments. Two-way ANOVA was performed to compare the mutant cells with the MeWo cells treated according to the same specified conditions. ; .
