Figure 3. D2HG Production and Secretion Increase NADPH Demands in IDH1+/R132C Cells.
(A) NADPH consumption fluxes by lipid synthesis and 2HG production in fibrosarcoma panel.
(B) Atom transition map of [3-2H]glucose.
(C) Contribution of oxPPP to cytosolic NADPH in fibrosarcoma panel.
(D) 2HG abundance in parental HT1080 cells upon treatment with 10 mM AGI-5198.
(E) Contribution of oxPPP to cytosolic NADPH in parental HT1080 cells with 10 mM AGI-5198.
(F) Contribution of oxPPP to cytosolic NADPH in non-native IDH1-R132H engineered HCT116 cells.
In (A), (C), (E), and (F), data are plotted as mean ± 95% confidence interval (CI). *Statistical significance by non-overlapping confidence intervals. In (D), data are plotted as mean ± SEM. Unless indicated, all data represent biological triplicates. See also Figure S2.
