Abstract
Atherosclerosis is one of the most important medical problems due to its prevalence and significant contribution to the structure of temporary and permanent disability and mortality. Atherosclerosis is a complex chain of events occurring in the vascular wall over many years. Disorders of lipid metabolism, inflammation, and impaired hemodynamics are important mechanisms of atherogenesis. A growing body of evidence strengthens the understanding of the role of genetic and epigenetic factors in individual predisposition and development of atherosclerosis and its clinical outcomes. In addition, hemodynamic changes, lipid metabolism abnormalities, and inflammation are closely related and have many overlapping links in regulation. A better study of these mechanisms may improve the quality of diagnosis and management of such patients.

Abstract
OBJECTIVES The changes in testosterone level and its correlation with the endothelial nitric oxide systems balance in patients with coronary artery disease (CAD) remains uncertain. Therefore, in our study, we aimed to evaluate the levels of testosterone, endothelin-1 (ET-1), nitric oxide (NO), and endothelial NOS (eNOS) in CAD patients, and control group to find the relationship between these parameters and disease severity. METHODS Forty-four patients as CAD group with significant (≥50%) stenosis confirmed by angiography was included in the study, and 40 healthy men were included as the control group. According to the number of vessels obstruction, CAD severity was determined. The serum indicated parameters were assessed to discriminate between patients and controls. RESULTS It was found that testosterone levels in the CDA group were significantly lower than those of the control group (p<0.05). In addition, the level of ET-1 in the CAD group was higher than that in the control group, but levels of NO and eNOS in observation were significantly lower than those in the control group (p<0.05). The correlation analysis revealed that testosterone was passivity correlated with serum NO levels (r=0.550, p=0.001). CONCLUSIONS The current study reports that serum levels of testosterone are closely related to endothelial NO levels and might be of relevance to the pathogenesis of endothelial dysfunction and disease severity in CAD patients.

Abstract
Background Endothelial nitric oxide synthase (eNOS) and potassium voltage-gated channel subfamily J member 11 (KCNJ11) could be the candidate genes for coronary artery disease (CAD). This study investigated the relationship of the eNOS (rs1799983) and KCNJ11 (rs5219) polymorphisms with the presence and severity of CAD in the North Indian population. Methods This study included 300 subjects, 150 CAD cases and 150 healthy controls. Single nucleotide polymorphism was evaluated by Polymerase chain reaction and Restriction fragment length polymorphism (PCR-RFLP). Analysis was performed by SPSS (version 21.0). Results We observed that KK genotype of KCNJ11E23K (rs5219) polymorphism (P=0.0001) genotypes and K allele (P=0.0001) was found to be a positive risk factor and strongly associated with CAD. In the case of eNOSG894T (rs1799983) there was no association found with CAD. Conclusion These results illustrate the probability of associations between SNPs and CAD although specific genetic polymorphisms affecting ion channel function and expression have still to be clarified by further investigations involving larger cohorts.

Association between NOS3 G894T, T-786C and 4a/4b Variants and Coronary Artery Diseases in Iranian Population. IRANIAN JOURNAL OF PUBLIC HEALTH 2018; 47:1891-1898. [PMID: 30788304 PMCID: PMC6379611] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 11/21/2022]
Abstract
BACKGROUND Endothelial nitric oxide synthase, encoded by NOS3, produces an atheroprotective metabolite. The G894T, T-786C and 4a/4b variants of this gene associated with increased risk for coronary artery diseases (CAD) have been evaluated in different populations worldwide, and inconsistent results have been obtained. We investigated the association between these three polymorphisms and presence of CAD in Iranian individuals. METHODS Overall, 234 people including angiography-positive patients from Amir-Almomenin Hospital (Heart Center), Kordkoy City, Golestan Province, northern Iran in 2016, angiography-negative subjects and healthy individuals from north of Iran were genotyped for the G894T and T-786C variations by PCR-RFLP, and 4a/4b VNTR only by PCR. RESULTS The genotype distribution and allelic frequencies for the three variants tested were not dramatically different between CAD and control subjects and also between CAD patients and people with pains and symptoms very similar to CAD but no stenosis (P>0.05). Moreover, the odds ratio for CAD related to the G894T (OR=1.09, 95% CI=(0.60-2.00), T-786C (OR=1.04, 95% CI=(0.57-1.89) and 4a/4b (OR=1.75, 95% CI=(0.92-3.32) variants did not show statistical significance. Similarly, the odds ratio for stenosis confirmed by angiography related to the 894T (OR=1.03, 95% CI= (0.61-1.74), -786C (OR=0.90, 95% CI=(0.54-1.50) and 4b (OR=1.64, 95% CI=(0.92 -2.93) alleles were not significant. CONCLUSION G894T, T-786C and 4a/4b variants were not associated with risk for CAD and occurrence of angiography-assessed stenosis in Northern Iranian population (P>0.05). These alleles might be population-specific and not to be associated with their corresponding gene pool. However, further analysis is required to clarify other CAD-correlated markers in our community.

Merz T, Stenzel T, Nußbaum B, Wepler M, Szabo C, Wang R, Radermacher P, McCook O. Cardiovascular disease and resuscitated septic shock lead to the downregulation of the H 2S-producing enzyme cystathionine-γ-lyase in the porcine coronary artery. Intensive Care Med Exp 2017; 5:17. [PMID: 28321823 PMCID: PMC5359268 DOI: 10.1186/s40635-017-0131-8] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2016] [Accepted: 03/13/2017] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Downregulation of the hydrogen sulfide (H2S)-producing enzymes cystathionine-γ-lyase (CSE), cystathionine-β-synthase (CBS), and/or 3-mercaptopyruvate sulfurtransferase (3-MST) is associated with chronic cardiovascular pathologies. Nevertheless, equivocal data are available on both the expression and function of these enzymes in coronary arteries (CA). We recently reported that atherosclerotic pigs subjected to sepsis developed impaired cardiac function, which coincided with decreased myocardial CSE expression and increased nitrotyrosine formation. To define the endogenous source(s) of H2S in the CA, we studied the expression of CBS, CSE, or 3-MST in the CA of pigs subjected to septic shock with/without pre-existing cardiovascular co-morbidity. METHODS Anesthetized and instrumented FBM "familial hypercholesterolemia Bretoncelles Meishan" pigs with high-fat diet-induced hypercholesterolemia and atherosclerosis were subjected to polymicrobial septic shock, or sham procedure, and subsequent intensive care therapy for 24 h. Young German domestic pigs were used as naïve controls. CSE, CBS, 3-MST, HO-1, eNOS, and nitrotyrosine expression was quantified by immunohistochemistry of formalin-fixed paraffin sections. RESULTS FBM pigs, in the absence of septic shock, showed decreased CSE expression in the media. This decrease became more pronounced after sepsis. The expression pattern of HO-1 resembled the pattern of CSE expression. CBS protein was not detected in the media of any of the CA examined but was localized to the adventitia and only in the atheromatous plaques containing foam cells of the CA, in regions that also displayed abundant nitrotyrosine formation. The CBS expression in the adventitia was not associated with nitrotyrosine formation. 3-MST expression was not found in any of the CA samples. CONCLUSIONS We hypothesize that (i) the reduced CSE expression in FBM pigs may contribute to their cardiovascular disease phenotype and moreover (ii) the further decrease in CA CSE expression in sepsis may contribute to the sepsis-associated cardiac dysfunction.

Abstract
Background Coronary heart disease is the leading cause of death and disability worldwide. Hypertension is a major independent risk factor for the development of CHD. Abnormalities in NO generation or activity have been proposed as a major mechanism of CHD. The purpose of this article is to determine the activity of eNOS and iNOS in patients with isolated CHD and CHD associated with HT of different age groups. Methods Fifty patients with isolated CHD and 42 patients with CHD associated with HT were enrolled in this study. NOS activity was determined by nitrite anion formed in the reaction. Results A statistically significant increase in iNOS activity is observed in elderly donors. In patients with isolated coronary heart disease cNOS activity is statistically significantly reduced with respect to the control group. The reduction of enzymatic activity of cNOS is more expressed in elderly patients than in middle-aged patients with coronary heart disease. Alterations in eNOS activity are more expressed in patients with coronary heart disease associated with hypertension than in patients with isolated coronary heart disease. Against the background of cNOS inhibition in the patients, a sharp increase in iNOS activity is observed. Conclusions It has been shown that disturbance of endothelial function in patients with coronary heart disease associated with hypertension is characterized by reduced endothelial NO synthesis by cNOS and increased systemic NO synthesis due to increased iNOS activity. It has been found that the lack of endothelial NO and hyperproduction of »harmful« NO by iNOS are more expressed in elderly patients.
