abstract
In BRAF V600E melanoma patients, RAF inhibitor treatment causes a MEK-inhibitor-sensitive, RAF-inhibitor-resistant adaptive reactivation of ERK signaling. In clinical trials combining MEK and RAF inhibitors, therapeutic efficacy was modestly enhanced, suggesting the utility of inhibiting feedback-reactivated pathways. Strategies for optimally inhibiting ERK signaling should be explored.
