Although mitogen-activated protein kinase (MAPK) inhibitors elicit initial regression of BRAF-mutated melanoma, drug resistance is an inevitable and fatal event. We recently reported that in genetically engineered mouse models of BRAF-mutated melanoma, isoform-selective phosphatidylinositol 3-kinase inhibition cooperates with MAPK pathway inhibition to forestall the onset of MAPK pathway inhibitor resistance.
