Abstract Among various genetic mutation in melanoma, BRAFV600E is one of the key drivers of melanoma initiation and progression and has become the frontline target in clinical trials. Although BRAF/MEK inhibitors show very promising therapeutic outcomes, recurrence or relapse is still a major challenge and its underlying mechanisms are still poorly understood. We hypothesized that survival of recurrent tumors is BRAF independent and relies on epigenetic reprogramming. To test our hypothesis, we used either pharmacological inhibition of BRAF/MEK or CRISPR/Cas9 mediated knockout of BRAF to create cell/tumor models of BRAF-independent survival.
