Oncogenic IDH1 Mutation Imparts Therapeutically Targetable Metabolic Dysfunction in Multiple Tumor Types

In this issue of Cancer Discovery, Thomas and colleagues leverage mass spectrometry metabolomics, stable isotope labeling, and functional studies to explore metabolic vulnerabilities in cancers harboring mutations in isocitrate dehydrogenase (IDH). The authors present compelling data to support the claim that dysregulated lipid synthesis underpins a synthetic lethal target in cancers with IDH1, but not IDH2, mutations.
