AIM To determine whether biliary cirrhosis could induce pancreatic dysfunction such as modifications in endothelial nitric oxide synthase(eNOS) expression and whether the regulation of eNOS could be altered by the regulatory proteins caveolin and heat shock protein 90 (Hsp90), as well as by the modifications of calmodulin binding to eNOS. METHODS Immunoprecipitations and Western blotting anal...
In mice, eNOS (endothelial nitric oxide synthase) maintains in vivo pancreatic secretory responses to carbachol or cholecystokinin octapeptide (CCK-8), maintains insulin sensitivity, and modulates pancreatic microvascular blood flow (PMBF). eNOS(-/-) mice are insulin resistant, and their exocrine pancreatic secretion is impaired. We hypothesized that the reduced exocrine pancreatic secretion in...
OBJECTIVE Changes in the expression of endothelial nitric oxide synthase (eNOS) in the peritoneum could be involved in the peritoneal dysfunction associated with peritoneal inflammation. The aim of the present study was to analyze the effect of Escherichia coli lipopolysaccharide (LPS) on eNOS expression in samples of human peritoneum. The effect of aspirin, a drug with anti-inflammatory proper...
In this study, we investigated molecular mechanism underlying the regulation of endothelial nitric oxide synthase (eNOS) expression by fibroblast growth factor 21 (FGF21). We analyzed FGF21 and eNOS expression in hypertensive and healthy (control) subjects (n=30/group). To evaluate the effects of FGF21 on endothelial cells, we transfected FGF21 mimics or FGF21 inhibitor into human umbilical vei...
Basic fibroblast growth factor (bFGF), epidermal growth factor (EGF), and vascular endothelial growth factor (VEGF) may play important roles in the placental vasculature, not only by controlling cell growth and differentiation, but also by mediating production of local vasodilators such as nitric oxide. As the mitogen-activated protein kinase (MAPK) signal cascade has been widely associated wit...
Significant impairment in endothelial-derived nitric oxide is present in the diabetic corpus cavernosum. RhoA/Rho-kinase may suppress endothelial nitric oxide synthase (eNOS). Here, we tested the hypothesis that RhoA/Rho-kinase contributes to diabetes-related erectile dysfunction and down-regulation of eNOS in the streptozotocin (STZ)-diabetic rat penis. Colocalization of Rho-kinase and eNOS pr...
PURPOSE Postconditioning, a series of brief ischemia-reperfusion sequences given before an ischemic heart undergoes sustained reperfusion, has been shown to lessen ischemia/reperfusion injury. The current study establishes a rabbit model of myocardial ischemia-reperfusion and studied the effects of pulmonary remote postconditioning in this model. METHODS Serum levels of creatine kinase (CK), ...
ATP leads to endothelial NO synthase (eNOS)/NO-mediated vasodilation, a process hypothesized to depend on the endothelial caveolar eNOS partitioning and subcellular domain-specific multisite phosphorylation state. We demonstrate herein that, in both the absence and presence of ATP, the uterine artery endothelial caveolae contain specific protein machinery related to subcellular partitioning and...
BACKGROUND Previously, we showed that the 27nt repeat polymorphism in endothelial nitric oxide synthase (eNOS) intron 4 was associated with altered eNOS mRNA and protein levels, nitric oxide (NO) production and vascular disease risk; the 27-nt repeats had a cis-acting role in eNOS promoter function. In the present study, we investigated nuclear protein that binds the 27nt repeat and mediates eN...
OBJECTIVE The Pin1 prolyl isomerase acts in concert with proline-directed protein kinases to regulate function of protein substrates through isomerization of peptide bonds that link phosphoserine or phosphothreonine to proline. We sought to determine whether Pin1 interacts with endothelial nitric oxide synthase (eNOS) in endothelial cells in a manner that depends on proline-directed phosphoryla...
