['3-bromopyruvate (3BrPA) is an antitumor agent able to inhibit aerobic glycolysis and oxidative phosphorylation, therefore inducing cell death. However, cancer cells are also highly dependent of glutaminolysis and tricarboxylic acid cycle (TCA) regarding survival and 3BrPA action in these metabolic routes is poorly understood.', 'The effect of 3BrPA was characterized in mice liver and kidney mitochondria, as well as in human HepG2 cells.', 'Low concentration of 3-BrPA significantly affected both glutaminolysis and TCA cycle functions, through inhibition of isocitrate dehydrogenase, α-ketoglutarate dehydrogenase and succinate dehydrogenase. Additionally, 3-BrPA treatment significantly decreased the reduced status of thiol groups in HepG2 cells without proportional increase of oxidizing groups, suggesting that these chemical groups are the target of alkylation reactions induced by 3-BrPA.'] Does 3-Bromopyruvic Acid inhibit Tricarboxylic Acid Cycle and Glutaminolysis in HepG2 Cells?
