the analysis of endothelial nitric oxide synthase gene polymorphism in intron 4 with hypertension disease
نویسندگان
چکیده
nitric oxide is an important vasorelaxant factor that it inhibits platelet adhesion and proliferation of smooth muscle cells. no is synthesized from l-arginine by means of endothelial nitric oxide synthase (enos) which is an isoform of nitric oxide synthase.in the present study, we examined possible association between the 27 base pair (bp) repeat polymorphism in intron 4 of the enos3 gene and hypertension in an iranian population. 40 patients with hypertension and 40 healthy controls were included in the research.genotyping was performed by polymorphism chain reaction (pcr). the frequency of 4a4a, 4a4b , 4b4b genotypes were 52.6% , 26.3%, 15.7% respectively in hypertension groups .the frequency of 4a4a, 4a4b , 4b4b genotypes were 73.8% , 15.7% , 10.5% respectively in control groups. the hypertensive patient group showed a significant higher frequency of the 4a allele compared to the controls (p<0.01).the present study showed a singificant association between the enos3 gene polymorphism and hypertension in the iranian population .

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...
متن کاملEndothelial nitric oxide synthase gene intron 4, 27 bp repeat polymorphism and essential hypertension in the Kazakh Chinese population.
To investigate the relationship between 27 bp repeat polymorphism in intron 4 in the endothelial nitric oxide synthase (eNOS4) gene and essential hypertension in the Kazakh Chinese population, 151 patients with essential hypertension and 138 healthy people were selected from the Boertonggu countryside of Shawan region in the Xinjiang uygur autonomous region of China in 2006. The polymorphism of...
متن کاملPolymorphism in intron 23 of the endothelial nitric oxide synthase gene (NOS3) is not associated with hypertension.
Nitric oxide (NO) is synthesised in the vascular endothelium by nitric oxide synthase (NOS3) and is an important factor in the regulation of blood pressure. Impaired synthesis of NO due to mutations in the NOS3 gene is associated with hypertension. To date several allelic variants of the NOS3 gene have been identified and their possible linkage with hypertension investigated. We studied the dis...
متن کاملAssociation between T-786C polymorphism of endothelial nitric oxide synthase gene and level of the vessel dilation factor in patients with coronary artery disease
Various polymorphisms on endothelial nitric oxide synthase (eNOs) gene cause reduced production of NO, the endothelial relaxing factor, and may accelerate the process of atherosclerosis. The study designed to investigate the frequency of T-786C polymorphism of the eNOs gene in patients suffering from coronary artery disease (CAD) in north-west of Iran. One hundred twenty subjects including 60 p...
