abstract：:BRAF inhibitors improve melanoma patient survival, but resistance invariably develops. Here we report the discovery of a novel BRAF mutation that confers resistance to PLX4032 employing whole-exome sequencing of drug-resistant BRAF(V600K) melanoma cells. We further describe a new screening approach, a genome-wide pigg...
