Abstract |
The role of cytochrome P4502E1 in metabolism of substances, polymorphism, ways of the expression regulation, change of activity in pathological condition is considered in the review. Cytochrome P4502E1 catalyzed first two reactions of acetone transformation in the lactic acid, ethanol oxidation, metabolism of fatty acids and their hydroperoxides. Cytochrome P4502E1 dependent metabolism of xenobiotics in many cases results in formation of toxic intermediates and radicals of oxygen. Regulation of cytochrome P4502E1 expression includes transcriptional mechanisms and substrate stabilization of its molecule. The enzyme activity grows in alcoholism, diabetes mellitus, obesity, steatohepatitis, administration of acetone, alcohols and is connected with intensification of toxicity of paracetamol, halothane, benzene, tetrachlororomethane and others xenobiotics. Such inhibitors of cytochrome P4502E1 as dialyl sulphide, disulfiram have hepatoprotective action.
