(F) Volcano plot showing the expression levels of BRAFi-resistant genes (identified in 501Mel by CRISPR-SAM screen) in 12 human melanoma cell lines. The fold change corresponds to the ratio of expression levels found in resistant and sensitive cell lines. In red: selected genes. EGFR is considered as positive control and SMAD3, BIRC3 and SLC9A5; selected as favorite genes for the next steps. SMAD3, BIRC3, SLC9A5 and AFAP1 are BRAFi-resistance genes and potent tumor-promoting genes (BRAFi for PBV
