Investigation of an inducible nitric oxide synthase gene (NOS2A) polymorphism in a multiple sclerosis population.

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) affecting most commonly the Caucasian population. Nitric oxide (NO) is a biological signaling and effector molecule and is especially important during inflammation. Inducible nitric oxide synthase (iNOS) is one of the three enzymes responsible for generating NO. It has been reported that there is an ex...

Investigation of a neuronal nitric oxide synthase gene (NOS1) polymorphism in a multiple sclerosis population.

Multiple Sclerosis (MS) is a chronic neurological disease characterized by demyelination associated with infiltrating white blood cells in the central nervous system (CNS). Nitric oxide synthases (NOS) are a family of enzymes that control the production of nitric oxide. It is possible that neuronal NOS could be involved in MS pathophysiology and hence the nNOS gene is a potential candidate for ...

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...

Aloe vera toxic effects: expression of inducible nitric oxide synthase (iNOS) in testis of Wistar rat

Objective(s): Nitric oxide (NO), a product of inducible nitric oxide synthase (iNOS), contributes in germ cell apoptosis. This study was aimed to evaluate the effects of Aloe vera gel (AVG) on male Wistar rat reproductive organ, serum NO level, and expression of iNOS gene in leydig cells. Materials and Methods:Adult male Wistar rats (n=36) were used for experiments in three groups. The experim...

Association 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...
