Figure 1. Reversing the perfect storm
Heterodimers of wild-type and mutant subunits of the metabolic enzymes IDH1/2 catalyze the production of (R)-2-hydroxyglutarate. Its accumulation impairs α-ketoglutarate–dependent dioxygenases, including those that modify DNA and histones (including the demethylation of 5-methylcytosine by TET-family hydroxylases and histone demethylases of the JmjC domain-containing family). This alters the epigenetic landscape, thereby blocking cell differentiation and promoting the acquisition of malignant features. Inhibitors (AGI-6780 and AGI-5198) that block (R)-2-hydroxyglutarate–producing IDH isoforms limit the growth of gliomaand AML-derived cancer cells.
