Changes in monoamine oxidase activity in hepatic injury: a review

Abstract

This review focuses on multiplicity of monoamine oxidase (MAO) activity in rat hepatic injury. MAO play a major role in the metabolism of biogenic amines. Stress such as immobilization stress (IMMO) or cold stress changes the multiple forms of MAO activity in rat liver. Thyroid hormone-inducible MAO inhibitor may play some role in regulating the MAO activity in rat liver. Carcinogen such as dimethylnitrosamine (DEN) might change the proportions of the forms of MAO activity in tumor cells. This compound is selective to and an irreversible inhibitor of MAO-B. These changes may account for the multiplicity of MAO by hepatic injury.
