Interaction Information:

Comment Application of NMR and MS-based tools led to the discovery of a critical link between pyruvate carboxylase (PC)-mediated pyruvate exchange with tricarboxylic acid (TCA) cycle intermediates (pyruvate cycling) and glucose-stimulated insulin secretion (GSIS) and demonstration that these pathways are dysregulated in lipid-cultured and dysfunctional beta-cells. One important pathway appears to involve export of citrate and/or isocitrate from the mitochondria via the citrate/isocitrate carrier (CIC) and subsequent conversion of isocitrate to alpha-ketoglutarate (alpha-KG) by the cytosolic NAPD-dependent isoform of isocitrate dehydrogenase (ICDc).
