Comparing glutathione peroxidase and glutathione reductase activity and their associations with cardiovascular measures in Africans and Caucasians : the SABPA study
… remodelling. The endogenous antioxidant enzymes glutathione peroxidase and glutathione reductase work synergistically to maintain intracellular redox balance. Both these enzymes have been indicated to have varying levels of activities with changes in blood pressure. Furthermore, GPx activity was …

The identification, purification and characterization of the fetal rat liver glutathione S-transferase isoenzyme YcYfetus
This study has examined the expression of the glutathione S-transferases (GSH S-T) in fetal rat livers in order to provide more information about the role played by this important group of enzymes in the fetus. The study commenced with an examination of the subunit composition of adult and fetal …

Biomarkers of oxidative stress and inflammation in biological samples collected from recurrent airway obstruction (RAO)-affected horses and their controls
… horses had significant alterations in cellular glutathione peroxidase (cGPx) activity, ascorbic acid and pH in a number of biological samples. Concentrations of 8-isoprostanes, isofurans, amino acids and mRNA expression of interleukin 4 (IL4), gamma interferon (INFγ), inducible nitric oxide …

Assessment of redox markers in cattle
… Se, along with peripheral blood mononuclear cell glutathione peroxidase, glutathione reductase, and reduced:oxidized glutathione were determined during summer grazing. Results suggested that endophyte consumption does not promote oxidative stress in cattle. Heat stress may alter glutathione redox …

The actions of gossypol on the physiologic antioxidant defense system
… several hepatic antioxidants including catalase, glutathione peroxidase, ascorbate and copper-zinc superoxide dismutase were decreased in gossypol treated rats. Catalase, glutathione peroxidase, ascorbate and glucose-6-phosphate dehydrogenase were decreased in the testis. In contrast, antioxidants …
