Signs and symptoms of this condition usually first appear shortly after birth, and they can vary widely among affected individuals. In experimental mouse models of acute liver failure, we found that two metabolic enzymes, namely pyruvate dehydrogenase complex and lactic dehydrogenase, translocate to the nucleus resulting in detrimental gene expression. Treatment with an inhibitor of these two enzymes was found to reduce liver damage and to improve survival. Pyruvate dehydrogenase is a large and complex molecule with interesting structural, catalytic and regulatory properties.
