The role of the endogenous antioxidant enzyme, glutathione S-transferase on cultured cardiomyocytes under oxidative stress conditions

The role of the endogenous antioxidant enzyme, glutathione S-transferase /GST/ on cultured cardiomyocytes under oxidative stress conditions

Inflammatory reaction without endogenous antioxidant response in Caco-2 cells exposed to iron/ascorbate-mediated lipid peroxidation.

To characterize the role of intestinal epithelial cells in mucosal host defense, we have examined endogenous antioxidant reactivity and inflammatory response in Caco-2 cell line. When differentiated Caco-2 cells were incubated with iron/ascorbate for 1-24 h, they exhibited increased malondialdehyde levels and decreased polyunsaturated fatty acid proportion in favor of saturated fatty acids. The...

The effect of arsenic and sodium nitroprusside on the physiological responses and antioxidant enzymes activity of Isatis cappadocica

Arsenic (As) stress, through the creation of oxidative stress, can cause phytotoxicity (e.g. The decrease of growth and chlorophyll content) in plants. Nitric oxide (NO), by promotion of the antioxidant system, plays an important role in reducing heavy metal-induced oxidative stress. In this study, the role of exogenously applied sodium nitroprusside (SNP; a NO donor) on physiological responses...

Effect of phosphorus stress on antioxidant enzyme activities in wheat seedlings (Triticum durum Desf.) under in vitro culture

The study investigates the role of root glutathione (GSH) content and glutathione S-transferase (GST) activity in the response of hard wheat (Triticum durum Desf. variety Carioca) induced by different doses of phosphorus KH2<span style="font-s...

Class-Pi of Glutathione S-Transferases

Class-Pi of glutathione s-transferases (GST-Pi) is the specific form of GSTs that are known to participate particularly in the mechanisms of resistance to drugs and carcinogens. This class of the enzyme is referred to as class-P or class-Pi or class π. The accepted terminology in this review article is class-Pi. In this article following a brief description of identified molecular forms of GSTs...
