Inhibition of surfactant function by copper-zinc superoxide dismutase (CuZn-SOD).

The efficacy of antioxidant enzymes to limit oxidant lung injury by instillation with surfactant mixtures in preterm infants with hyaline membrane disease is under investigation. However, there is concern that instillation of proteins in the alveolar space may inactivate pulmonary surfactant. We studied the effects of bovine copper-zinc superoxide dismutase (CuZn-SOD) on the biophysical propert...

CuZn - superoxide dismutase ( CuZnSOD ) transgenic mice show

_, We have used female and male transgenic (Tg) mice that carry the complete sequence of the human copper-zinc (CuZn) , superoxide dismutase (SOD) gene in order to assess the lethal effects of methylenedioxyamphetamine (MDA) and methylene,_ im dioxymethamphetamine (MDMA). In contrast to non-Tg mice, both heterozygous and homozygous SOD-Tg mice showed resistance to the lethal effects of both dru...

Superoxide levels and function of cerebral blood vessels after inhibition of CuZn-SOD.

The goal of this study was to examine the role of endogenous copper/zinc (CuZn)-superoxide dismutase (SOD) on superoxide levels and on responses of cerebral blood vessels to stimuli that are mediated by nitric oxide (acetylcholine) and cyclooxygenase-dependent mechanisms (bradykinin and arachidonic acid). Levels of superoxide in the rabbit basilar artery were measured using lucigenin-enhanced c...

Overexpression of CuZn-SOD prevents lipopolysaccharide-induced endothelial dysfunction.

BACKGROUND AND PURPOSE Inflammation is thought to be a major contributor to carotid artery disease. Lipopolysaccharide (LPS) activates inflammatory mechanisms thought to contribute to endothelial dysfunction by mechanisms that are not well defined. The goal of this study was to determine whether overexpression of CuZn-SOD protects against LPS-induced increases in superoxide and endothelial dysf...

Differential expression of EC-SOD, Mn-SOD and CuZn-SOD in rat lung exposed to crystalline silica.

Superoxide dismutases (SODs) are antioxidant enzymes that catalyze the dismutation of superoxide into hydrogen peroxide. There are 3 kinds of isozymes: extracellular superoxide dismutase (EC-SOD), manganese-containing superoxide dismutase (Mn-SOD) and copper- and zinc-containing superoxide dismutase (CuZn-SOD). To examine the expression of SOD isozymes in lungs injured by crystalline silica, we...
