CDK6 and melanoma: Additionally, analysis of DepMap datasets demonstrated that FRA1 levels significantly correlate with AXL, CDK6, and FSCN1 expression in 1673 cell lines of all cancer types (Fig. 5H) and 110 melanoma cell lines (Supplementary S4A) and that FRA1 protein expression also correlates with AXL, CDK6, and Fascin levels in 20 melanoma cell lines (Supplementary S4B).
