Several oxidative and non-oxidative stresses were applied to two transgenic strains of Drosophila melanogaster (designated P(bSOD)5 and P(bSOD)11) that express superoxide dismutase (SOD) at elevated levels, and control strains that express normal SOD levels. Transgenic strain P(bSOD)5 exposed to...
Oxidation of low density lipoprotein (LDL) has been shown to occur in the artery wall of atherosclerotic lesions in both animal models and human arteries. The oxidant(s) responsible for initiating this process are under intensive investigation and 15-lipoxygenase has been suggested in this...
Extracellular-superoxide dismutase type C (EC-SOD C) is a secretory SOD isoenzyme which, in contrast to the intracellular CuZn SOD, has affinity to the endothelium and a long vascular half-life. In the present study, the effects of EC-SOD C and CuZn SOD on reperfusion-induced myocardial damage...
The technique of E.S.R. spectroscopy, when employed in conjunction with a continuous flow system, provides direct evidence for the nature of free radicals formed from organic substrates in the presence of Fe II and H 2 O 2 in aqueous solution. It is shown, both via the identification of...
Antioxidant properties of thioctic and dihydrolipoic acid have been demonstrated in membranes and low density lipoproteins (LDL) in vitro. In vivo studies with dietary supplementation of thioctic acid to rats showed that it can also protect tissues against oxidative damage. Presumably, this...
Ascorbate peroxidase active component (APAC) was purified and characterized in Synechococcus PCC 9742 (R2) cells. APAC was isolated from freshly harvested cells, by ion exchange chromatography on DEAE cellulose, ultrafiltration through a 3000 dalton cut off filter and high pressure liquid...
It has been suggested that CuZn-superoxide dismutase (CuZnSOD) is required for the establishment of an interferon (IFN)-mediated antiviral state. To investigate this possibility further, a panel of 6 stably transfected HeLa clones, expressing CuZnSOD activity from 1.6 to 7.3 times the normal...
