Cancer metabolism discovery uncovers new role of IDH1 gene mutation in brain cancer

Agios Pharmaceuticals today announced that its scientists have established, for the first time, that the mutated IDH1 gene has a novel enzyme activity consistent with a cancer-causing gene, or oncogene. This breakthrough discovery shows that the mutated form of IDH1 produces a metabolite, 2-hydroxyglutarate (2HG), which may contribute to the formation and malignant progression of gliomas, the most common type of brain cancers. This discovery appears to reverse the previously held belief that IDH1 was non functional for cancer-causing activity. It is also one of the first reported instances where a metabolic enzyme such as IDH1 is shown to play a role in cancer formation, in this case through altered metabolic activity.
