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 کاملNitric Oxide, Superoxide, Hydrogen Peroxide, and Peroxynitrite
The evanescent nature of reactive oxygen and nitrogen species, the multiple cellular mechanisms evolved to maintain these substances at low (submicromolar) concentrations within the vascular system, and the often multifaceted nature of their reactivities have made measurement of these compounds within the vasculature problematic. This review attempts to provide a critical description of some of...
متن کاملEffect of lead on nitric oxide synthase expression in coronary endothelial cells: role of superoxide.
Chronic exposure to low levels of lead causes hypertension (HTN) in humans and animals. We have previously shown that increased reactive oxygen species (ROS) leads to enhanced NO inactivation, depressed NO bioavailability, and compensatory upregulation of NO synthases (NOSs) in rats with lead-induced HTN. We have further demonstrated increased ROS generation with lead exposure in cultured endot...
متن کاملAdiponectin-induced endothelial nitric oxide synthase activation and nitric oxide production are mediated by APPL1 in endothelial cells.
Adiponectin protects the vascular system partly through stimulation of endothelial nitric oxide (NO) production and endothelium-dependent vasodilation. The current study investigated the role of two recently identified adiponectin receptors, AdipoR1 and -R2, and their downstream effectors in mediating the endothelium actions of adiponectin. In human umbilical vein endothelial cells, adiponectin...
