Cancer & fly models

Reitman ZJ, Sinenko SA, Spana EP, Yan H. Genetic dissection of leukemia-associated IDH1 and IDH2 mutants and D-2-hydroxyglutarate in Drosophila. Blood. 2015 Jan 8;125(2):336-45. PMID: 25398939; PMCID: PMC4287640.

From the abstract: “Gain-of-function mutations in nicotinamide adenine dinucleotide phosphate-dependent isocitrate dehydrogenase (IDH)1 and IDH2 frequently arise in human leukemias ... We expressed the R195H mutant of Drosophila Idh (CG7176), which is equivalent to the human cancer-associated IDH1-R132H mutant, in fly tissues ... We identified the fly homolog of D-2-hydroxyglutaric acid dehydrogenase (CG3835), which metabolizes D-2HG, and showed that coexpression of this enzyme with mutant Idh abolishes mutant Idh-associated phenotypes. These results provide a flexible model system to interrogate a cancer-related genetic and metabolic pathway ...”
