Cytochrome P450 2E1 (CYP2E1) is a key enzyme in the mammalian metabolism of several low molecular weight volatile organic compounds (VOCs), such as trichloroethylene (TCE), vinyl chloride (VC), carbon tetrachloride (CT), benzene, chloroform, and bromodichloromethane (BDCM), which are all common environmental pollutants that pose risks to human health.

In the present study, we fed male Wistar rats at five levels of food intake for one day, including conventional feeding (60 kcal), three of DR (45, 30, and 15 kcal), and fasting (0 kcal), and observed the metabolic changes of hepatic cytochrome P450 2E1 (CYP2E1) and the hepatotoxicity of chloroform (CHCl (3)) and carbon tetrachloride (CCl (4)).

In previous studies from our laboratory, the presence in highly purified liver nuclei of metabolic pathways for processing ethanol (EtOH), N-nitrosodimethylamine (NDMA), carbon tetrachloride and chloroform was reported.

This compound is converted to a cytotoxic metabolite, phosgene, by CYP2E1 in liver and/or kidney.
The approaches discussed are illustrated using chloroform as a case study.

Although hepatic cells are generally considered to be vulnerable and susceptible to various organic solvents, particularly chloroform and other halogenated hydrocarbons, the hepatotoxic effects of aromatic hydrocarbons including toluene have not yet been sufficiently characterized.
The immunoreactivities of heat shock proteins (HSP-70 and HSP-90) and cytochrome P4502E1 (CYP2E1) in the liver were analyzed to assess the hepatotoxic damage induced by toluene inhalation, and the expression of these histological markers was shown to be substantially enhanced by the subacute exposure to toluene vapor.

Proc Natl Acad Sci U S A. 2007 Oct 23;104(43):16816-21. Epub 2007 Oct 16.

Small, volatile hydrocarbons, including trichloroethylene, vinyl chloride, carbon tetrachloride, benzene, and chloroform, are common environmental pollutants that pose serious health effects.
We have developed transgenic poplar (Populus tremula x Populus alba) plants with greatly increased rates of metabolism and removal of these pollutants through the overexpression of cytochrome P450 2E1, a key enzyme in the metabolism of a variety of halogenated compounds.
