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...
متن کاملDietary isothiocyanates, glutathione S-transferase polymorphisms and colorectal cancer risk in the Singapore Chinese Health Study.
Dietary intake of cruciferous vegetables (Brassica spp.) has been inversely related to colorectal cancer risk, and this has been attributed to their high content of glucosinolate degradation products such as isothiocyanates (ITCs). These compounds act as anticarcinogens by inducing phase II conjugating enzymes, in particular glutathione S-transferases (GSTs). These enzymes also metabolize ITCs,...
متن کاملGlutathione S-transferase activity and glutathione S-transferase mu expression in subjects with risk for colorectal cancer.
The glutathione S-transferases (alpha, mu, and pi), a family of Phase II detoxication enzymes, play a critical role in protecting the colon mucosa by catalyzing the conjugation of dietary carcinogens with glutathione. We investigated the efficacy of using the glutathione S-transferase (GST) activity of blood lymphocytes and GST-mu expression as biomarkers of risk for colorectal cancer. GST acti...
متن کاملExpression of glutathione, glutathione peroxidase and glutathione S-transferase pi in canine mammary tumors
BACKGROUND Glutathione (GSH) is one of the most important agents of the antioxidant defense system of the cell because, in conjunction with the enzymes glutathione peroxidase (GSH-Px) and glutathione S transferase pi (GSTpi), it plays a central role in the detoxification and biotransformation of chemotherapeutic drugs. This study evaluated the expression of GSH and the GSH-Px and GSTpi enzymes ...
متن کاملExpression of glutathione S-transferase during rat liver development.
The ontogeny of rat liver glutathione S-transferase (EC 2.5.1.18) (GSTs) during foetal and postnatal development was investigated. The GSTs are dimers, the subunits of which belong to three multigene families, Alpha (subunits 1, 2, 8 and 10), Mu (subunits 3, 4, 6, 9 and 11) and Pi (subunit 7) [Mannervik, Alin, Guthenberg, Jennsson, Tahir, Warholm & Jörnvall (1985) Proc. Natl. Acad. Sci. U.S.A. ...
