Reconstitution of the interplay between cytochrome P450 and human glutathione S-transferases in clozapine metabolism in yeast.

Expression of cytochrome P450 and glutathione S-transferase in human bone marrow mesenchymal stem cells

Currently several studies are being carried out on various properties of mesenchymal stem cells (MSCs)however there are a few investigations about drug metabolizing properties of these cells. The aim of thisstudy was to measure the key factors involved in drug metabolism in human bone marrow MSCs. For thispurpose, cellular glutathione (GSH), glutathione Stransferase (GSTs) and...

Cytochrome P450 expression in oesophageal cancer.

The cytochrome P450 superfamily of enzymes play a central part in the metabolism of carcinogens and anti-cancer drugs. The expression, cellular localisation, and distribution of different forms of P450 and the functionally associated enzymes epoxide hydrolase and glutathione S-transferases have been investigated in oesophageal cancer and non-neoplastic oesophageal tissue using immunohistochemis...

Xenobiotic metabolising enzyme expression in colonic neoplasia.

The cytochrome P450, epoxide hydrolase, and glutathione S-transferase enzyme families play an important part in the metabolism of many carcinogens and anti-cancer drugs. The expression of two forms of cytochrome P450 (P450 1A and P450 3A), epoxide hydrolase and of the alpha, mu, and pi forms of glutathione S-transferase in normal colon, colonic adenomas, and adenocarcinoma of the colon were stu...

Susceptibility to esophageal cancer and genetic polymorphisms in glutathione S-transferases T1, P1, and M1 and cytochrome P450 2E1.

Genetic polymorphisms in enzymes involved in carcinogen metabolism have been shown to influence susceptibility to cancer. Cytochrome P450 2E1 (CYP2E1) is primarily responsible for the bioactivation of many low molecular weight carcinogens, including certain nitrosamines, whereas glutathione S-transferases (GSTs) are involved in detoxifying many other carcinogenic electrophiles. Esophageal cance...
