Figure 4. Effect of chemoresistance on fumarate and succinate isotopomer ratios. Isotopomer ratios for (A) fumarate and (B) succinate in BCNU-sensitive (9L-S) and BCNU-resistant (9L-R) glioma cells in the absence and presence of 40 mM DCA. Bars (mean ± SD) with different letters are significantly different from each other at P ≤ 0.05
