Two genes encoding manganese superoxide dismutase (sod-2 and sod-3) have been identified in the nematode Caenorhabditis elegans. Each gene is composed of five exons, and intron positions are identical; however, intron sizes and sequences are not the same. The predicted protein sequences are 86.3% homologous (91.8% conservative), and the cDNAs are only 75.2% homologous. Both deduced protein sequ...
Superoxide dismutase (SOD) is used to manage chronic pain, including neuropathic and inflammatory pain. However, data regarding the clinical effectiveness are conflicting and the neurophysiological mechanism of SOD has yet to be elucidated. The aim of the present study was to investigate whether SOD relieved chronic central pain (CCP) following spinal cord injury (SCI) and the possible underlyi...
PURPOSE To evaluate corneal endothelial morphology in mice without secreted extracellular superoxide dismutase (SOD) in normal ageing and in a lipopolysaccharide (LPS)-induced inflammation model and to measure the contents of SOD isoenzymes in the mouse cornea and the superoxide radical concentrations in corneas with and without extracellular SOD. METHODS The central corneal endothelium of wi...
Superoxide dismutase (SOD) is an important antioxidant that protects many types of cells from the free radical damage. One of the possible ways for the use of SOD is its incorporation in liposomes. The aim of this study was to investigate the effect of cationic phospholipids on the entrapment of human erythrocyte superoxide dismutase (Cu/Zn SOD) in liposomes. Also, in the present study, w...
Accumulating evidence suggests that changes in both 5-hydroxytryptamine (5-HT) receptor activity and in the levels of reactive oxygen species (ROS) play an important role in regulating pulmonary artery (PA) vascular responsiveness, particularly in the setting of pulmonary hypertension. Therefore, we hypothesized that increased levels of superoxide enhance 5-HT-induced PA constriction. With the ...
PURPOSE Pancreatic ductal adenocarcinoma (PDA) cells are known to produce excessive amounts of reactive oxygen species (ROS), particularly superoxide, which may contribute to the aggressive and refractory nature of this disease. Extracellular superoxide dismutase (EcSOD) is an antioxidant enzyme that catalyzes the dismutation of superoxide in the extracellular environment. This study tests the ...
Extracellular superoxide dismutase (EC-SOD), the only known enzymatic scavenger of extracellular superoxide, may modulate reactions of nitric oxide (NO) in the lungs by preventing reactions between superoxide and NO. The regulation of EC-SOD has not been examined in developing lungs. We hypothesize that EC-SOD plays a pivotal role in the response to increased oxygen tension and NO in the neonat...
