A complementary DNA clone from human placenta, encoding human extracellular superoxide dismutase (EC-SOD; superoxide:superoxide oxidoreductase, EC 1.15.1.1), has recently been isolated and characterized. An expression plasmid, based on the EC-SOD complementary DNA, was transfected into Chinese hamster ovary cells (CHO-K1). The transfected cells secreted human EC-SOD to the culture medium. The s...
OBJECTIVES To explore whether there is a difference in the frequency of postendoscopic retrograde cholangiopancreatography (ERCP) pancreatitis in patients with manometrically confirmed sphincter of Oddi dysfunction (SOD) types I, II, and III. METHODS A retrospective review of all of the patients who underwent an ERCP with SOD type I or patients with manometrically confirmed SOD type II or typ...
Abnormal reactive oxygen species (ROS) production is associated with defective sperm function. Superoxide dismutase (SOD) is related with the scavenging of seminal ROS. We aimed to determine the effect of SOD activities of spermatozoa and seminal plasma on sperm quality. Semen samples from infertile couples who consented to the analyses were divided into two groups: 1) normospermia (n = 20); an...
Photosynthesis of leaf discs from transgenic tobacco plants (Nicotiana tabacum) that express a chimeric gene that encodes chloroplast-localized Cu/Zn superoxide dismutase (SOD+) was protected from oxidative stress caused by exposure to high light intensity and low temperature. Under the same conditions, leaf discs of plants that did not express the pea SOD isoform (SOD-) had substantially lower...
BACKGROUND Cu,Zn-superoxide-dismutase, Cu,Zn-SOD, can be obtained from different sources with different anti-inflammatory activities. In this study we compared the anti-inflammatory capacity of the marine yeast Debaryomyces hanseii Cu,Zn-SOD (Dh-SOD) with that of bovine erythrocytes (Be-SOD) in a preventive and a therapeutic fashion. METHODS Edema was induced by carrageenan injection into the...
PURPOSE To evaluate the age-induced changes in corneal endothelial morphology in mice lacking the cytosolic copper-zinc superoxide dismutase (SOD-1), the interstitial extracellular superoxide dismutase (SOD-3), or both of these SOD isoenzymes. METHODS The central corneal endothelial morphologies of old C57BL-6J wild type (n=19), SOD-1 null (n=16), SOD-3 null (n=15), and SOD1/3 null (n=11) mic...
Ulcerative colitis (UC) involves intestinal mucosal damage induced by reactive oxygen species (ROS), in particular, superoxide anion. Superoxide dismutase (SOD) catalyzes dismutation of superoxide anion to hydrogen peroxide, which is subsequently detoxified by catalase. Lecithinized SOD (PC-SOD) is a new modified form of SOD that has overcome previous clinical limitations of SOD. In this study,...
Superoxide dismutase 2 (SOD-2) is synthesized in the cytosol and imported into the mitochondrial matrix, where it is activated and functions as the primary antioxidant for cellular respiration. The specific mechanisms that target SOD-2 to the mitochondria remain unclear. We hypothesize that inducible heat shock protein 70 (iHSP70) targets SOD-2 to the mitochondria via a mechanism facilitated by...
