Figure 6. Altered anaplerotic contributions in CTP-deficient cells.
A) Selected malate and citrate MIDs in cells cultured in [U-13C]glutamine.
B) Selected malate and citrate MIDs in cells cultured in [U-13C]glucose.
C) Selected malate and citrate MIDs in cells cultured in [3,4-13C]glucose to assess flow through pyruvate carboxylase (PC).
D) Western-blot of PC expression in CTP-WT and CTP-KO cells.
Data are displayed as mean ± S.D. *, p<0.05, two-way ANOVA followed by Sidak’s multiple comparisons test. n=3 cultures of a representative experiment. All experiments were repeated 3 times. Two independent pools of CTP-KO clones (pools KO1 and KO2) were analyzed for all experiments.
