Pyruvate dehydrogenase (PDH) is identified as a crucial mediator of BRAFV600E-induced cellular senescence: PDH is activated by BRAF-mediated suppression of PDK1, enhancing oxidative glucose metabolism, and PDK1 depletion eradicates mutant BRAF melanomas, indicating that this relationship between cell senescence and metabolism might be exploited therapeutically.
