Metabolic reprogramming of pyruvate dehydrogenase is essential for the proliferation of glioma cells expressing mutant IDH1

Mutations in isocitrate dehydrogenase 1 (IDH1) characterize most adult low-grade gliomas. Mutant IDH1 catalyzes production of the oncometabolite 2-hydroxyglutarate (2-HG). We recently discovered that the IDH1 mutation also reprograms pyruvate metabolism in a 2-HG-dependent manner, and that reprogramming of pyruvate metabolism is essential for cell proliferation in glioma cells with mutant IDH1.
