Direct Inhibition of RAS Reveals the Features of Oncogenic Signaling Driven by RAS G12 and Q61 Mutations

Abstract

RAS inhibition in multiple tumor types reveals the difference between G12 mutants and Q61 mutants in their cooperation with upstream regulators and downstream effectors to promote oncogenic signaling. Our findings provide the rationale for combinatorial approaches and contribute to explaining the nonuniform distribution of RAS mutations, de novo and at resistance.
