TL;DR: It is shown that cancer-associated IDH1 mutations result in a new ability of the enzyme to catalyse the NADPH-dependent reduction of α-ketoglutarate to R(-)-2-hydroxyglutarate (2HG), and that the excess 2HG which accumulates in vivo contributes to the formation and malignant progression of gliomas.

TL;DR: It is reported that tumor 2HG is elevated in a high percentage of patients with cytogenetically normal acute myeloid leukemia (AML), and AML patients with IDH mutations display a significantly reduced number of other well characterized AML-associated mutations and/or associated chromosomal abnormalities, potentially implicating IDH mutation in a distinct mechanism of AML pathogenesis.

TL;DR: The recent discovery of mutations in metabolic enzymes has rekindled interest in harnessing the altered metabolism of cancer cells for cancer therapy, and isocitrate dehydrogenase 1 (IDH1), which is mutated in multiple human cancers, is examined.

TL;DR: Evidence is provided that inhibitors targeting mutant IDH2/R140Q could have potential applications as a differentiation therapy for cancer, and a small molecule, AGI-6780, that potently and selectively inhibits the tumor-associated mutant IDh2/ R140Q is developed.

TL;DR: IDH1/2 mutations confer an enzymatic gain of function that dramatically increases 2-HG in AML, providing an explanation for the heterozygous acquisition of these mutations during tumorigenesis.
