Analysis of T-786C and 4a/b endothelial nitric oxide synthase gene polymorphisms in retinopathy of prematurity

Endothelial nitric oxide synthase gene T−786C and 27-bp repeat gene polymorphisms in retinopathy of prematurity

PURPOSE Retinopathy of prematurity (ROP), which is associated with abnormal retinal vessel development, is the leading cause of visual loss in preterm infants. Endothelial nitric oxide synthase (eNOS) is believed to play a central role in both retinal angiogenesis and vasculogenesis. The aim of this study was to investigate functional genetic polymorphisms of eNOS in the pathogenesis of ROP. ...

Association 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...

The Study of Nitric Oxide Synthase 3 (NOS3) T-786C and 4a4b Gene Polymorphism in Iranian Men with Varicocele

Background and Objectives: Varicocele is one of the most common causes of male infertility. Varicocele is an abnormal dilatation and tortuosity of veins of the pampiniform plexus, which drain the testis. Studies have shown that elevated level of oxidative stress markers, such as nitric oxide (NO) in the dilated veins of patients with varicocele impair testicular function. The aim of this study,...
