Figure 6. Inactivation of CDK4 or VWF inhibits the proliferation of melanoma. (A, B) CDK4 or VWF expression in the si-CDK4 or si-VWF group was significantly lower than that in the Control and si-Control groups. (C, D) EdU-positive cells of the si-CDK4 or si-VWF group was significantly reduced than that of the Control and si-Control groups. Asterisks indicate statistically significant difference (*: p<0.05, **: p<0.01, one-way ANOVA).
