A Role for Cytosolic Isocitrate Dehydrogenase as a Negative Regulator of Glucose Signaling for Insulin Secretion in Pancreatic ß-Cells
Figure 3
Reduction in IDHc expression alters fatty acid metabolism without affecting oxidative glucose metabolism.
Transfected cells were incubated at 1, 5 or 10(G) and results were normalized by protein content. A, Glucose oxidation and B, Glucose incorporation into free fatty acids were monitored using [U-14C]glucose. C, Fatty acid oxidation was measured using [1-14C]palmitate. D, Malonyl-CoA levels determined using an enzymatic assay. Data represent means ± SEM of two (A) or three (B, C and D) independent experiments each performed in triplicate cell culture wells. * p<0.05; ** p<0.01, vs ScrAB under the same incubation condition, by one-way Anova, Dunnett's post-test.
