Abstract

Senescence bypass through p16 loss predisposes to transformation and tumorigenesis. Buj et al. found that the loss of p16 upregulates nucleotide metabolism through increased mTORC1-mediated translation of RPIA to bypass senescence in an RB-independent manner. Thus, the mTORC1-RPIA axis is a metabolic vulnerability for p16-null cancers.
