Together with the elevation in glucose+taurine/tCho (1.72 ± 1.59 vs. 0.99 ± 0.86) and lactate/tCho (1.77 ± 1.78 vs. 0.79 ± 0.0.92) metabolite ratios, these observations suggest that IDH2 mutated gliomas might favor oxidative phosphorylation over aerobic glycolysis compared to IDH1 due to metabolic reprogramming associated with IDH mutation. The gene discussed is IDH2; the disease is central nervous system cancer.
