Constitutively active ERK signalling stimulates cell proliferation, thereby contributing to tumorigenesis. We now learn that ERK activity induces phosphorylation and MDM2-mediated degradation of the tumour-suppressing transcription factor FOXO3a, thus gaining new information on valuable targets for human cancer therapeutic intervention.
