Mutant p53 exerts oncogenic functions by modulating cancer cell metabolism

The metabolic function of p53 is important for its oncosuppressive function. Mutant p53 (mutp53) with gain of oncogenic function can regulate cell metabolism. Our recent study revealed a novel transcription-independent mechanism for a gain-of-function mutp53 that directly inhibits activation of adenosine monophosphate-activated protein kinase (AMPK) to promote cancer cell metabolism.
