EXPRESSION OF INDUCIBLE NITRIC OXIDE SYNTHASE GENE (iNOS) STIMULATED BY HYDROGEN PEROXIDE IN HUMAN ENDOTHELIAL CELLS
Inducible nitric oxide synthase (iNOS) gene expresses a calcium calmudolin-independent enzyme which can catalyse NO production from L-arginine. The induction of iNOS activity has been demonstrated in a wide variety of cell types under stimulation with cytokines and lipopoly saccharide (LPS). Previous studies indicated that all nitric oxide synthases (NOS) activated in human umbilical vein endot...
متن کاملRole of matrix metalloproteinase II on analgesic effect of nitric oxide inhibition in rat
Abstract Introduction: Matrix metalloproteinase 2 is one of the inflammatory mediators that is involved in nociceptive processing and its production is regulated by many inflammatory factors such as nitric oxide. We studied the role of MMP-2 on the analgesic effects of nNOS inhibitor. Methods: Considering that nitric oxide has many roles in pain processing, we studied the CSF levels of MMP-2 ...
متن کاملComparison of inducible nitric oxide synthase activity in pancreatic islets of young and aged rats
Objective(s):Some pathologic situations such as diabetes and metabolic syndrome are associated with alternation in nitric oxide level. Incidence of these condition increases with aging. On the other hand, insulin secretion is modulated by nitric oxide, and nitric oxide synthase (NOS) activity is also altered in diabetes. In this study, modification in the enzyme activity associated with aging a...
متن کاملThe Effect of L-NAME on Morphine Antinociception in Formalin Test
Introduction: N- nitro-L-arginine methyl ester (L-NAME), one of the L-arginine analogs, has been specified as an inhibitor of nitric oxide synthase ( NOS).Nitric oxide synthase is an enzyme which leads to nitric oxide synthesis. Since nitric oxide has been known as a pain mediator, it can be said that L-NAME can decrease and relieve pain. In this research the effect of L-NAME on morphine antino...
متن کاملNitric Oxide Functions; an Emphasis on its Diversity in Infectious Diseases
Nitric oxide is a short-lived mediator, which can be induced in a variety of cell types and produces many physiologic and metabolic changes in target cells. It is important in many biological functions and generated from L-arginine by the enzyme nitric oxide synthase. Nitric oxide conveys a variety of messages between cells, including signals for vasorelaxation, neurotransmission and cytotoxici...
