Abstract

We studied the role of mitochondria in insulin-induced inactivation of protein tyrosine phosphatases in the liver. The mitochondrial respiratory chain is an insulin-sensitive source of H2O2that acts as a physiological inhibitor of protein tyrosine phosphatases. Succinate dehydrogenase plays a key role in insulin-stimulated generation of H2O2and inactivation of liver protein tyrosine phosphatases.
