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 کاملAssociation of endothelial nitric oxide synthase gene G894T polymorphism with type two diabetes and diabetic nephropathy
Background: Nitric oxide (NO) produced by endothelial NO synthase (eNOS) mediates a large range of processes, and abnormality in the production of NO has been implicated in diabetic complications including diabetic nephropathy (DN). G894T polymorphism in the eNOS gene has been shown to decreased activity the NO levels of plasma. The association between eNOS Glu298Asp gene polymorphism and DN ri...
متن کاملNitric oxide produced by endothelial nitric oxide synthase promotes diuresis.
Extracellular fluid volume is highly regulated, at least in part, by peripheral resistance and renal function. Nitric oxide (NO) produced by NO synthase type 3 (NOS 3) in the nonrenal vasculature may promote fluid retention by reducing systemic vascular resistance and arterial pressure. In contrast, NO produced by renal NOS 3 promotes water excretion by reducing renal vascular resistance, incre...
متن کاملRelation of endothelial nitric oxide synthase gene to plasma nitric oxide level, endothelial function, and blood pressure in African Americans.
BACKGROUND The role of eNOS gene polymorphisms on plasma nitrite or nitrate (NOx) level, endothelial function, and blood pressure (BP) remains unclear. METHODS We estimated the relationship of eNOS polymorphisms (the T(-786)C in the 5'-flanking promoter region, T(-786)C; 27-bp repeat in intron 4, eNOS4; and Glu298Asp in exon 7, G894T) with plasma NOx level, brachial endothelial function asses...
متن کاملGene transfer of endothelial nitric oxide synthase improves relaxation of carotid arteries from diabetic rabbits.
BACKGROUND Diabetes mellitus is associated with impairment of NO-mediated vascular relaxation. The purpose of this study was to determine whether adenovirus-mediated gene transfer of endothelial NO synthase (eNOS) or Cu/Zn superoxide dismutase (SOD1) improves responsiveness to acetylcholine in alloxan-induced diabetic rabbits. METHODS AND RESULTS After 8 weeks, plasma glucose was greater in d...
