We have previously observed upregulation of PDK4 in high-grade compared with low-grade bladder cancers. The pyruvate dehydrogenase complex (PDC) 3 catalyzes the oxidative decarboxylation of pyruvate with the formation of acetyl-CoA, CO 2 and NADH (H +) (1 – 3). As a result, citrate synthesis is decreased and tricarboxylic acid cycle (TCA) cycle intermediates are diminished.
