In vitro experiments suggest that free radicals may contribute importantly to atherogenesis. Superoxide dismutase (SOD), particularly extracellular SOD (EC-SOD), which accounts for the majority of SOD biological activity, is a major superoxide scavenger. We explored factors that may affect plasma EC-SOD levels measured by ELISA and assessed the association between plasma EC-SOD and coronary art...
The distribution of CuZn superoxide dismutase (SOD) molecules in subcellular organelles in rat liver hepatocytes was studied using integrated biochemical, stereological, and quantitative immunocytochemical techniques. A known concentration of purified CuZn SOD in 10% gelatin was embedded alongside the liver tissue for the calculation of CuZn SOD concentrations in hepatocyte organelles and total...
Lipopolysaccharide (LPS) treatment increases survival of rats, but not of mice, during hyperoxia. Manganese superoxide dismutase (Mn SOD) in the lung plays a critical role in LPS-induced tolerance to hyperoxia in rats. Therefore, we now compared the response of lung Mn SOD with treatment of mice and rats with LPS. LPS treatment of rats increased Mn SOD activity and protein concentration, did no...
Extracellular superoxide dismutase (EC-SOD), also known as SOD3, is an antioxidant expressed at high levels in normal adult kidneys. Because oxidative stress contributes to a variety of kidney injuries, we hypothesized that EC-SOD may be protective in CKD progression. To study this hypothesis, we used a murine model of ADR nephropathy characterized by albuminuria and renal dysfunction. We found...
