The oncometabolite 2-hydroxyglutarate inhibits histone lysine demethylases.
EMBO Rep., 12:463-469, 2011

PubMed Abstract: Mutations in isocitrate dehydrogenases (IDHs) have a gain-of-function effect leading to R(-)-2-hydroxyglutarate (R-2HG) accumulation. By using biochemical, structural and cellular assays, we show that either or both R- and S-2HG inhibit 2-oxoglutarate (2OG)-dependent oxygenases with varying potencies. Half-maximal inhibitory concentration (IC(50)) values for the R-form of 2HG varied from approximately 25 μM for the histone N(ɛ)-lysine demethylase JMJD2A to more than 5 mM for the hypoxia-inducible factor (HIF) prolyl hydroxylase. The results indicate that candidate oncogenic pathways in IDH-associated malignancy should include those that are regulated by other 2OG oxygenases than HIF hydroxylases, in particular those involving the regulation of histone methylation.
