eNOS (endothelial NO synthase) plays a critical role in the development of ventricular remodelling and cardiac hypertrophy. The purpose of the present study was to determine whether three common variants in NOS3 (the eNOS gene) are associated with the risk of LVH [LV (left ventricular) hypertrophy] in patients with essential hypertension. Three NOS3 genetic variants, -T786C (rs2070744), eNOS4a/...
Background Varicocele is an abnormal dilation and tortuosity of veins of pampiniform plexus that drains the testis and causes an important change in semen.This abnormality is often one of the most common risk factors for male infertility. The aim of this study was to investigate the relationship between nitric oxide synthase 3 (NOS3) 4a4b (rs61722009) gene polymorphism, as a common genetic fact...
OBJECTIVE The purpose of this study was to simultaneously monitor the transcriptional levels of 12 endothelial growth factor genes in response to alterations in wall shear stress (WSS) under conditions relevant to the development of intimal hyperplasia, a major cause of arterial bypass graft failure. METHODS Human umbilical vein endothelial cells were preconditioned in vitro under steady flow...
background: migraine is a chronic neurological disorder, characterized by recurrent moderate to severe headaches. worldwide migraine a=ects nearly 15%. studies suggest that genes involved in the production of nitric oxide (no) may act as genetic factors for migraine. no synthase 3 (nos3) by expressing enzyme nos regulates endothelial derived no. one class of medications used as f...
BACKGROUND The nitric oxide (NO) pathway is involved in asthma, and eosinophils participate in the regulation of the NO pool in pulmonary tissues. We investigated associations between single nucleotide polymorphisms (SNPs) of NO synthase genes (NOS) and biological NO-related phenotypes measured in two compartments (exhaled breath condensate and plasma) and blood eosinophil counts. METHODOLOGY...
Background—Significant variation exists within the endothelial nitric oxide synthase (NOS3) gene that may influence cardiovascular risk. The Asp variant of NOS3 has a shorter half-life in endothelial cells. Given the importance of nitric oxide in the heart failure syndrome, we evaluated the effect of this variant on event-free survival in a population with systolic dysfunction. Methods and Resu...
In addition to its hemodynamic effects, nitric oxide (NO) may play a role in the renal tubular handling of sodium. Experiments were conducted to determine possible changes in renal nitric oxide synthase-3 (NOS3) expression in rats treated with deoxycorticosterone acetate (DOCA) and high salt. All rats were uninephrectomized, and either a placebo or DOCA pellet was implanted subcutaneously. Plac...
