| R183W mutant of PPP2R1A, the gene encoding the PP2A Aalpha scaffolding subunit, failed to suppress tumor growth in vivo through activation of the MAPK pathway in RAS-mutant transformed cells. Cells expressing R183W were less sensitive to MEK inhibitors. Results demonstrate that the R183W mutation in PPP2R1A potentiates oncogenic signaling and reduces drug sensitivity of RAS-mutant cells to MEK inhibitors. | Inactivation of PP2A by a recurrent mutation drives resistance to MEK inhibitors.
