Metabolic utilization of exogenous pyruvate by mutant p53 (R175H) human melanoma cells promotes survival under glucose depletion.

Abstract excerpt

Dominant-negative (DN) p53 mutations in the tumor suppressor p53 gene partly contribute to human cancer progression by inactivating the remaining wild type allele. Since tumor cells face glucose and growth factor shortage when growing distant from sites of vascularization, we used genetically-matched human C8161 melanoma harbouring wt p53 or a tumor-associated (DN) mutant p53 (R175H), to investigate whether this...
