Tumor adaptation and resistance to RAF inhibitors.

Abstract excerpt

RAF kinase inhibitors have substantial therapeutic effects in patients with BRAF-mutant melanoma. However, only rarely do tumors regress completely, and the therapeutic effects are often temporary. Several mechanisms of resistance to RAF inhibitors have been proposed. The majority of these cause ERK signaling to become insensitive to treatment with RAF inhibitors by increasing the amount of RAF dimers in cells,...
