Mechanisms of acquired resistance to BRAF V600E inhibition in colon cancers converge on RAF dimerization and are sensitive to its inhibition

R Yaeger, Z Yao, DM Hyman, JF Hechtman, E Vakiani… - Cancer research, 2017 - AACR
Abstract BRAF V600E colorectal cancers are insensitive to RAF inhibitor monotherapy due
to feedback reactivation of receptor tyrosine kinase signaling. Combined RAF and EGFR …
