Abstract excerpt
Isocitrate dehydrogenases 1 and 2 (IDH1/2) are homodimeric enzymes that catalyze the conversion of isocitrate to α-ketoglutarate (α-KG) in the tricarboxylic acid cycle. However, mutant IDH1/2 (mIDH1/2) reduces α-KG to the oncometabolite 2-hydroxyglutarate (2-HG). High levels of 2-HG competitively inhibit the α-KG-dependent dioxygenases involved in histone and DNA demethylation, thereby impairing normal cellular...
