Micro RNA ‐125a promotes resistance to BRAF inhibitors through suppression of the intrinsic apoptotic pathway

Abstract excerpt

Summary Melanoma patients with BRAFV600E‐mutant tumors display striking responses to BRAF inhibitors (BRAFi); however, almost all invariably relapse with drug‐resistant disease. Here, we report that microRNA‐125a (miR‐125a) expression is upregulated in human melanoma cells and patient tissues upon acquisition of BRAFi resistance. We show that miR‐125a induction confers resistance to BRAFV600E melanoma cells to...
