Reduced eNOS activity could mediate an increased stroke risk through hypertension or independent of hypertension through abnormal vasomotor responses, promoting atherogenesis, or increased platelet adhesion and aggregation.
The intensity of NOS2 and NOS3 gene expression observed in athlete's heart was similar to dilated cardiomyopathy with low LV diastolic stiffness-modulus and preserved LV stroke work.
Endothelial nitric oxide exerts a variety of protective effects on endothelial cells and blood vessels, and therefore the nitric oxide synthase 3 gene (NOS3) is a logical candidate gene for stroke susceptibility.
These results demonstrate that bortezomib promotes eNOS dependent vascular protection, and reduces NF-kappaB dependent vascular disruption, all of which may contribute to neuroprotection after stroke.
Using large sample sizes and a replication study approach, we found evidence for a role of a polymorphism in the nitric oxide synthase 3 gene in stroke onset.

We aimed to study whether variations in vasoregulatory endothelial nitric oxide synthase (eNOS 4a/b) and tissue-injury-associated inducible nitric oxide synthase (iNOS R5/4) genes and smoking might explain gender differences in long-term survival after stroke.
Results demonstrate that the eNOS protein within the medulla may play a significant role in mediating cardiovascular responses during static exercise in pathophysiological conditions, such as stroke.

In order to investigate the influence of genetic factors in childhood stroke, we compared the distributions of mutations/ polymorphisms affecting hemostasis and/or endothelial function (factor V [FV] Leiden, factor II [FII] G20210A, methylenetetrahydrofolate reductase [MTHFR] C677T, angiotensin-converting enzyme [ACE] insertion/deletion [ID], and endothelial nitric oxide synthase [eNOS] G894T) among children with stroke and controls.
We tested a single nucleotide polymorphism (SNP) in endothelial nitric oxide synthase (NOS3) gene at codon 298 (single-nucleotide polymorphism rs1799983; p.Asp298Glu) in a cohort of 355 older (>75 years) stroke survivors, who had detailed cognitive assessments from 3 months poststroke, i.e., baseline when the patients were free of dementia and subsequently at annual intervals.
We observed significant associations with NOS3 variants and CHD and heart failure and significant pharmacogenetic effects for stroke and all cause mortality.
Our results highlight NOS1 as a susceptibility factor for stroke, but do not corroborate previous NOS3 association findings with stroke risk. nNOS is known to play a major role in atherosclerosis development and in blood flow regulation, and it is plausible that its influence in stroke may be mediated through these two main clinical risk factors.
