Disease relevance of NOS1

  • Loss of NOS1 expression in high-grade renal cell carcinoma associated with a shift of NO signalling [1].
  • CONCLUSION: Based upon the consistent allelic associations, we believe that further evaluation of the NOS1 gene in ESRD susceptibility in African-Americans is warranted [2].
  • The aim of this study was to investigate whether the number of AAT repeats in intron 20 of the NOS1 gene, recently associated with variations in FENO in adults with asthma and cystic fibrosis, was associated with the raised FENO in healthy atopic children [3].
  • Western blot analysis showed that the n-NOS expressed in neuroblastoma cells was a 160-kDa protein reacted with anti-n-NOS antibody [4].
  • In patients with COPD, neuronal NOS expression correlated negatively with the degree of the airway obstruction (%FEV1 predicted) [5].
 

Psychiatry related information on NOS1

  • The present study examines the existence and location of the constitutive isoform eNOS (endothelial NO synthase) accompanying the already substantiated neurogenic NOS (nNOS) in the human corpus cavernosum of men with and without erectile dysfunction [6].
  • The expression of neuronal nitric oxide (nNOS) and inducible nitric oxide (iNOS) as isoforms of the nitric oxide synthase (NOS) as well as nitrotyrosine as an end product of protein nitration was analyzed in sections of temporal cortex taken from postmortem brains of patients with Alzheimer's disease (AD) [7].
  • We also show that the expression of the anti-NOS gene, which functions as a negative regulator of nNOS expression, is downregulated in the CGC by training at 4 h after conditioning, during the critical period of NO requirement [8].
  • Importantly, our results establish that the expression of nNOS gene is essential for normal feeding behavior [9].
 

High impact information on NOS1

  • NO derived from the constitutive isoforms of NOS (nNOS and eNOS) and other NO-adduct molecules (nitrosothiols) have been shown to be modulators of bronchomotor tone [10].
  • A common genetic variant in the NOS1 regulator NOS1AP modulates cardiac repolarization [11].
  • Neuronal nitric oxide synthase (nNOS) is concentrated at synaptic junctions in brain and motor endplates in skeletal muscle [12].
  • OVA/OVA endothelial (NOS3)-deficient mice were significantly more responsive to methacholine challenge compared with similarly treated NOS1 and NOS1&3-deficient mice [13].
  • New insights into nNOS regulation of vascular homeostasis [14].

Biological context of NOS1

 

Anatomical context of NOS1

 

Associations of NOS1 with chemical compounds

  • Both the Arg inhibitors N-hydroxy-nor-l-arginine and BEC dose-dependently increased basal contractility in rat myocytes, which was inhibited by both nonspecific and NOS1-specific NOS inhibitors N(G)-nitro-l-arginine methyl ester and S-methyl-l-thiocitrulline, respectively [23].
  • RESULTS: All these techniques led to consistent results showing that epithelial cells of most tubules along the human nephron exhibit functional NOS1, with a corticomedullary gradient observed both at the protein and mRNA levels [24].
  • Finally, the staining pattern of protein tyrosine nitration, assessed by immunohistochemistry, parallelled that of NOS1 expression in normal renal parenchyma and benign tumours, supporting the concept that protein nitration was accounted for by NOS1 activity [1].
  • A higher intensity expression of NOS1 and NOS3 was recorded in the tissues around titanium, whereas, on the contrary, a lower intensity of expression was found in the tissues around zirconium oxide specimens [27].
  • Although several mechanisms are proposed to explain the reduction of cNOS activity, reduced substrate availability, caused by a combination of increased arginase activity and decreased cellular uptake of L-arginine, appears to play a key role [28].
 

Physical interactions of NOS1

  • In the ischemic and failing myocardium, iNOS expression is induced and further contributes to attenuate the inotropic effect of catecholamines, as does eNOS coupled to overexpressed beta3-adrenoceptors. nNOS expression also increases in the aging and ischemic heart, but its role (compensatory or deleterious) remains to be defined [29].
  • A chimera consisting of the nNOS heme domain and FMN binding subdomain and the CYPOR FAD binding subdomain catalyzed significantly increased rates of cytochrome c reduction in the absence of CaM and of NO synthesis in its presence [30].
  • The effect of HSP90 is mediated by the enhancement of CaM binding to nNOS [31].
 

Enzymatic interactions of NOS1

  • CaM-K Ialpha and CaM-K IV failed to phosphorylate nNOS at Ser(847) in transfected cells [32].
 

Co-localisations of NOS1

 

Regulatory relationships of NOS1

  • Furthermore, NO produced from newly induced neuronal NOS was reported to induce expression of thioredoxin and several other genes for preconditioning-induced neuroprotection [34].
  • We conclude that mitochondrial Arg II negatively regulates NOS1 activity, most likely by limiting substrate availability in its microdomain [23].
  • Endothelial NOS was evenly expressed in all groups while neuronal NOS was undetectable [35].
  • Thus, we attempted to study whether or not a decrease of dystrophin expression would induce a modification in nNOS expression in cultured human neurons [36].
  • NMMA blocked completely the somatostatin stimulated increase of cGMP levels and nNOS was detected in rat retina. cGMP immunoreactivity was observed primarily in bipolar cells only of nitroprusside-treated retinas [37].
 

Other interactions of NOS1

  • Both growth factor-independent (HMC-1) and -dependent (LAD 2) MC lines showed predominant nuclear eNOS protein localization, with weaker cytoplasmic expression. nNOS showed exclusive cytoplasmic localization in HMC-1 [38].
  • Immunoblotting analysis using frontal tissue homogenates at 15, 28, 40 weeks of gestation and 18 months of age revealed single band corresponding to SOD1 molecular weight, observed at all stages examined; a single band compatible with the nNOS molecular mass was detected only at the 28th week of gestation [39].
  • The NOS1 intron 2 GT repeat and STAT6 exon 1 GT repeat were associated with asthma [22].
  • The carbachol-induced corticosterone response was significantly increased by pretreatment with nNOS inhibitor L-NNA and was considerably reduced by indomethacin, a general COX inhibitor [40].
  • Microsatellite markers NOS1B (NOS1), D7S636 (NOS3) and CPHD1-1/2 (EDN-1) were genotyped in the sample [2].
