Abstract
Background E-selectin has been shown to play a role in atherosclerosis and to be increased in HIV-infected individuals due to chronic immune activation. There is a paucity of studies on E-selectin in HIV-infected treatment-naïve individuals. Objectives This study aimed to determine whether E-selectin levels were increased in HIV-infected treatment-naïve individuals and whether these correlated with markers of disease severity, inflammation and coagulation to determine if this population is at risk for cardiovascular disease (CVD). Methods E-selectin levels were determined in 114 HIV-infected treatment-naive and 66 HIV-negative individuals, compared between groups and correlated with markers of disease severity, inflammation and coagulation. Results There were statistically significant differences (p<0.01) in levels of WCC, CD4+ count, %CD38/8, albumin, IgG, hsCRP and D-dimer between groups and no statistically significant differences in E-selectin (p=0.84) and fibrinogen (p=0.65) levels. E-selectin correlated with age (p=0.02) and gender (p=0.01). Conclusion E-selectin was a poor marker in this setting. There was no correlation with any of the markers of disease severity, inflammation and coagulation. E-selectin is most likely raised in an acute inflammatory setting, rather than chronic stage of HIV-infection. We recommend that other markers be utilized to identify patients at increased risk of CVD; as these were significantly increased untreated in individuals.

Gbadoe KM, Berdouzi N, Aguiñano AAA, Ndiaye NC, Visvikis-Siest S. Cardiovascular diseases-related GNB3 C825T polymorphism has a significant sex-specific effect on serum soluble E-selectin levels. JOURNAL OF INFLAMMATION-LONDON 2016; 13:39. [PMID: 27990099 PMCID: PMC5148858 DOI: 10.1186/s12950-016-0146-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/31/2016] [Accepted: 12/02/2016] [Indexed: 12/20/2022]
Abstract
Background The C825T polymorphism (rs5443) of the Guanine Nucleotide-Binding protein subunit β3 (GNB3) gene has been associated with obesity, essential hypertension, atherosclerosis, coronary diseases, and cerebrovascular events, but with some sex-specific effects. Its association with inflammatory mediators such as cell adhesion molecules has not been studied, although they are heavily involved in cardiovascular diseases’ (CVDs) processes. The aim of our study was then to investigate a possible sex-specific effect of the GNB3 C825T polymorphism on serum soluble cell adhesion molecules such as E, P and L-selectins (sE, sP and sL-selectins). Results Participants were from the STANISLAS Family Study and were free of chronic disease as CVDs or cancer. We included in total 771 subjects aged 6 to 58 years (391 males (50.71%) and 380 females (49.29%)). No significant association of rs5443 was observed in the whole population with serum sE, sP and sL-selectins after adjusting for age, sex, body mass index, systolic blood pressure, anti-inflammatory drugs and hormonal drugs consumption. A significant interaction of rs5443 was observed with sex for sE-selectin (p < 0.001), but not for sP and sL-selectins. After adjusting for covariables, the T allele was significantly associated with an additive increase effect on serum sE-selectin levels in males (β = 5.03 ± 2.18; p = 0.020), while a significant additive decrease effect was observed in females (β =−4.46 ± 2.06; p = 0.030). These associations stayed significant after correction for multiple tests (p = 0.045 in males and in females). The additive phenotypic variance was 21.54% in males versus 1.91% in females. Conclusions In our Caucasian population, the GNB3 C825T polymorphism showed a significant sex-specific effect on serum sE-selectin levels, with a disadvantage for males, as increased sE-selectin levels has been associated with CVDs outcomes. The T allele has been previously associated with the same CVDs as increased sE-selectin, but more often in males. The link we observed between this polymorphism and E-selectin is then consistent with previous findings, and helps to better understand the deleterious effect of the GNB3 825 T allele on CVDs outcomes in males. We revealed in this study an important pathway through which the GNB3 gene induces CVDs’ outcomes.

Abstract
UNLABELLED Genetic variation is thought to contribute to the etiology of hypertension, and E-selectin is a candidate essential hypertension-associated gene. OBJECTIVE In this study, we attempted to test the hypothesis that subtle haplotype variants of SELE genes may be sources of essential hypertension in Mongolian and Han populations. MATERIALS A total of 429 unrelated Mongolian herdsmen and 416 Han farmers were enrolled, including 212 Mongolian essential hypertension (EH) patients, 217 Mongolian normotensives (controls), 200 Han EH patients and 216 Han normotensives (controls). METHODS All nine tag single-nucleotide polymorphisms (SNPs) within the SELE gene were retrieved from HapMap and the genotyping was performed using a polymerase chain reaction (PCR)/ligase detection reaction assay. Results The distributions of the A-allele frequency of rs3917458 and the C-allele frequency of rs2179172 differed significantly between the hypertensive subjects and controls in the Han population. The frequency of haplotype GGC was significantly higher in the EH group than in the controls in the Mongolian population. In the Han population, a significant difference was observed in the haplotype frequency of TCC between the patients and controls, whereas haplotype ACA was detected significantly less often in the EH subjects than in the controls. CONCLUSION Meanwhile, the haplotype TCC in the Han hypertensive patients and the haplotype GGC in the Mongolian patients had independent effects in increasing the risk for EH and maybe used as risk factors for predicting high blood pressure. However, the haplotype ACA had an independent effect in decreasing the risk of hypertension and may be protective in normotensive subjects in the Han population. Therefore, multiple SNPs in combination in SELE may confer a risk of hypertension.

Abstract
Nax , an α-subunit of the sodium channel encoded by the SCN7A gene, has been deemed to be a sensor of the concentration of sodium in the brain and may be involved in salt intake behavior. We inferred that Nax /SCN7A may participate in the regulation of blood pressure and the pathogenesis of essential hypertension (EH). The present case-control study involving 615 hypertensives and 617 normotensives was performed to investigate the association between SCN7A polymorphisms and EH in the Northern Han Chinese population. The three common single nucleotide polymorphisms (SNPs) (rs3791251, rs6738031, rs7565062) in the exons of SCN7A were genotyped with the TaqMan assay. Significant association between SNP rs7565062 and EH was found under the addictive and dominant genetic models (P = 0.024, OR = 1.283, 95%CI [1.033-1.592]; P = 0.013, OR = 1.203, 95%CI [1.040-1.392]; respectively). The three SNPs were in close pair-wise linkage disequilibrium with each other and the haplotype analyses indicated that haplotype G-A-T was significantly associated with increased risk of EH (P = 0.023, OR = 1.290). In conclusion, our data showed that SNP rs7565062 of SCN7A was significantly associated with EH and the allele T of rs7565062 or the related haplotype G-A-T will be a genetic risk factor for EH in the Northern Han Chinese population.

Abstract
BACKGROUND The A561C polymorphism of the E-selectin gene (SELE) has been reported to be associated with essential hypertension (EH) in several studies; however, results among these studies were inconsistent. Here, we conducted a meta-analysis to explore the association of the A561C polymorphism with EH. METHODS Publications were retrieved through searching PubMed, Web of Science, the China National Knowledge Infrastructure (CNKI), China Biological Medicine, and the Wanfang database. Odds ratios (OR) and 95 % confidence intervals (CI) were calculated to estimate the strength of association of A561C with EH. Subgroup analysis was also performed to assess ethnic discrepancies. A total of seven studies comprising 2,127 EH patients and 2,078 controls were analyzed. RESULTS In the dominant model analysis, we found significant associations between the A561C polymorphism and EH in all subjects (CC+AC vs. AA, OR = 1.96, 95 %CI 1.57-2.44, P heterogeneity = 0.381), in a Han Chinese subgroup (CC+AC vs. AA, OR = 2.38, 95 %CI 1.73-3.29, P heterogeneity = 0.269), and in non-Han Chinese minorities (CC+AC vs. AA, OR = 1.62, 95 %CI 1.19-2.21, P heterogeneity = 0.84). CONCLUSION The findings suggest that C allele carriers of the SELE gene polymorphism (A561C) might be predisposed to EH in the Chinese population. Further investigations in other ethnic populations should be conducted to verify these findings.

Abstract
Objective Epidemiological studies have shown that E-selectin gene polymorphisms (A561C and C1839T) may be associated with essential hypertension (EH), but the results are conflicting in different ethnic populations. Thus, we performed this meta-analysis to investigate a more authentic association between E-selectin gene polymorphisms and the risk of EH. Methods We searched the relevant studies for the present meta-analysis from the following electronic databases: PubMed, Embase, Cochrane Library, Google Scholar, Web of Science, Wanfang Data, and China National Knowledge Infrastructure (CNKI). Odds ratios (OR) with 95% confidence interval (CI) were used to evaluate the strength of the association between E-selectin gene polymorphisms and EH susceptibility. The pooled ORs were performed for dominant model, allelic model and recessive model. The publication bias was examined by Begg’s funnel plots and Egger’s test. Results A total of eleven studies met the inclusion criteria. All studies came from Asians. Ten studies (12 cohorts) evaluated the A561C polymorphism and EH risk, including 2,813 cases and 2,817 controls. The pooled OR was 2.280 (95%CI: 1.893–2.748, P<0.001) in dominant model, 5.284 (95%CI: 2.679–10.420, P<0.001) in recessive model and 2.359 (95%CI: 1.981–2.808, P = 0.001) in allelic model. Four studies (six cohorts) evaluated C1839T polymorphism and EH risk, including 1,700 cases and 1,681 controls. The pooled OR was 0.785 (95%CI: 0.627–0.983, P = 0.035) in dominant model, 1.250 (95%CI: 0.336–4.652, P = 0.739) in recessive model and 0.805 (95%CI: 0.649–0.999, P = 0.049) in allelic model. Conclusion The current meta-analysis concludes that the C allele of E-selectin A561C gene polymorphism might increase the EH risk in Asian population, whereas the T allele of E-selectin C1839T gene polymorphism might decrease the EH risk.

Abstract
In order to explore the potential association between the leptin receptor (LEPR) gene polymorphisms and essential hypertension (EH) risk in the Northern Han Chinese population, we recruited 823 hypertensive subjects and 491 healthy control subjects from the Northern Han Chinese. Genotyping was performed to identify the Lys109Arg, Gln223Arg and Lys656Asn polymorphisms of the LEPR gene. Significant associations were found in a dominant genetic model ([GG+AG] vs AA), P=0.007, odds ratio (OR)=3.697, 95% confidence interval (CI) 1.442–9.482), and in homozygote comparison (GG vs AA, P=0.005, OR=3.890, 95% CI 1.501–10.077) for the Gln223Arg polymorphism. No significant association could be found between Lys109Arg or Lys656Asn polymorphism and EH risk. Linkage disequilibrium was detected between the Lys109Arg and Gln223Arg polymorphisms, and haplotype analyses identified that the G-A haplotype was a protective haplotype for EH. Our studies demonstrated that the LEPR Gln223Arg polymorphism had an important role in a patient's susceptibility to EH in the Northern Han Chinese population.

Abstract
BACKGROUND Hypertension is a serious health issue worldwide and essential hypertension, which includes 90-95% of the cases, is influenced by both genetic and environmental factors. Identification of these factors may help in control of this disease. The Insertion/Deletion (I/D) polymorphism in Angiotensin-Converting Enzyme (ACE) gene and rs2106809 (C > T) polymorphism in Angiotensin-Converting Enzyme 2 (ACE2) gene have been reported to be associated with essential hypertension in different populations. AIM To investigate the association of ACE I/D and ACE2 rs2106809 polymorphisms with essential hypertension in the population of Odisha, an eastern Indian state. SUBJECTS AND METHODS A total of 246 hypertensives (159 males and 87 females) and 274 normotensives (158 males and 116 females) were enrolled in the study. Detailed anthropometric data, tobacco, alcohol and food habits were recorded and 2 ml of venous blood was collected for biochemical and genetic analysis. RESULTS The DD genotype of ACE and TT genotype of ACE2 were significantly high among female hypertensives, while T allele of ACE2 was linked to male hypertensives. In the male population, alcohol was also identified as a potential risk factor. CONCLUSION Among females, ACE I/D and ACE2 rs2106809 polymorphisms, while among males, ACE2 rs2106809 polymorphism and alcohol consumption are associated with essential hypertension in the study population.

Abstract
BACKGROUND We examined the association between 14 endothelial system genes and salt-sensitivity of blood pressure (BP). METHODS After a 3-day baseline examination, during which time the usual diet was consumed, 1,906 Chinese participants received a 7-day low-sodium diet (51.3 mmol of sodium/day) followed by a 7-day high-sodium diet (307.8 mmol of sodium/day). BP measurements were obtained at baseline and at the end of each intervention using a random-zero sphygmomanometer. RESULTS The DDAH1 rs11161637 variant was associated with reduced BP salt sensitivity, conferring attenuated systolic BP (SBP) and mean arterial pressure (MAP) decreases from baseline to the low-sodium intervention (both P = 2×10(-4)). Examination of genotype-sex interactions revealed that this relation was driven by the strong associations observed in men (P for interactions = 1.10×10(-4) and 0.008, respectively). When switching from the low- to high-sodium intervention, increases in diastolic BP (DBP) and MAP were attenuated by the COL18A1 rs2838944 minor A allele (P = 1.41×10(-4) and 1.55×10(-4), respectively). Conversely, the VWF rs2239153 C variant was associated with increased salt sensitivity, conferring larger DBP and MAP reductions during low-sodium intervention (P = 1.22×10(-4) and 4.44×10(-5), respectively). Ten variants from 3 independent SELE loci displayed significant genotype-sex interactions on DBP and MAP responses to low-sodium (P for interaction = 1.56×10(-3) to 1.00×10(-4)). Among men, minor alleles of 4 correlated markers attenuated BP responses to low-sodium intake, whereas minor alleles of another 4 correlated markers increased BP responses. No associations were observed in women for these variants. Further, qualitative interactions were shown for 2 correlated SELE markers. CONCLUSIONS These data support a role for the endothelial system genes in salt sensitivity.

Abstract
PURPOSE Mitofusin2 gene (Mfn2, also named Hyperplasia suppressive gene, HSG) is very important in the origin and development of hypertension. However, the mechanism of Mfn2/HSG expression regulation was not uncovered. This study was designed to explore the association of a novel 5'-uncoding region (UCR) -1248 A>G variation of HSG/Mfn2 gene and hypertension. MATERIALS AND METHODS 472 healthy, normotensive subjects [normotension (NT) group], 454 prehypertensive subjects [prehypertension (PH) group] and 978 hypertensive patients [essential hypertension (EH) group] were screened for an association study between 5'-UCR -1248 A>G of Mfn2/HSG and hypertension by polymerase chain reaction and DNA sequencing after venous blood was drawn and DNA was extracted. RESULTS When comparing the A and G frequency in EH, PH and NT groups, in total, NT group significantly had higher A frequency than in PH group [odds ratio (OR)=1.605, confidence interval (CI) 95%=1.063-2.242, p=0.025] and EH group (OR=5.395, CI 95%=3.783-7.695, p<0.01). When subgrouped by gender, A frequency in NT group was still significantly higher than in EH group (male: OR= 4.264, CI 95%=2.780-6.543, p<0.01; female: OR=8.897, CI 95%=4.686-16.891, p<0.01), but not from PH group, either in male group or in female group. Ordinal Logistic Regression analysis showed that A>G variation was significantly related with blood pressure level (B=-1.271, Wald=40.914, CI 95%=-1.660 - -0.881, p<0.01). CONCLUSION 5'-UCR -1248 A>G variation of Mfn2/HSG gene was a novel variation and may be associated with hypertension in Chinese.

Abstract
BACKGROUND E-selectin is an adhesion molecule expressed on activated endothelial cells. E-selectin plays an important role in the process of inflammation and is also involved in the mechanism of cancer metastasis regulating the adhesion of circulating cancer cells to the blood vessels. The aim of our study was to determine whether an association exists between its most common gene polymorphism, S128R, and gastric cancer (GC).
METHODS We performed a case-control study of 88 GC cases and 480 controls to analyze the association between E-selectin S128R gene polymorphism and GC susceptibility. The genotyping analysis was done by PCR-restriction fragment length polymorphism method.
RESULTS The E-selectin S128R C allele, CA and CC genotypes were over-represented among the GC cases. No statistically significant association was observed between E-selectin S128R polymorphisms and tumor characteristics. However, carrying the C allele was associated with poor survival.
CONCLUSIONS The E-selectin S128R C allele may confer an increased susceptibility to gastric cancer development and correlate with a poor prognosis.

Abstract
OBJECTIVE Circulating biomarkers of endothelial dysfunction and inflammation are elevated in late pregnancy in women with preeclampsia. We examined plasma levels of inflammatory cytokines and adhesion molecules in early pregnancy, to assess their ability to predict preeclampsia. METHODS In a prospective longitudinal study, 2600 women with singleton pregnancies and no history of hypertension were recruited at their antenatal hospital (booking) visit at gestational week 12-16. Of these, 49 (1.9%) developed preeclampsia, whereas 74 women matched for age and BMI with uncomplicated pregnancies were selected as controls. A subset of women with risk factors for preeclampsia were sampled again at gestational weeks 16 and 28 (11 cases, 39 controls) and postnatally (six cases, 36 controls). RESULTS From multiplex analysis, soluble E-selectin concentrations were higher at 12-16 weeks in women who subsequently developed preeclampsia (15.1 ± 4.9 versus 12.9 ± 4.5 ng/ml, P = 0.02). At gestational week 28, E-selectin concentrations were again higher in women who went on to develop preeclampsia compared with controls (14.4 ± 5.6 versus 10.7 ± 3.5 ng/ml, P = 0.010), whereas levels were not different between the two groups in postpartum samples. CONCLUSION Changes in soluble E-selectin concentration in early pregnancy may reflect underlying pathophysiological processes, potentially providing mechanistic insights into preeclampsia.

Abstract
Experimental and clinical observations suggest that E-selectin could have an important role in essential hypertension (EH), but the relationship between common E-selectin variants and EH has not been extensively studied in the Chinese population. In this study, we explored the association between two common variants in the E-selectin gene (rs5361A/C and rs5355C/T) and EH in the Uygur, Kazakh and Han populations in the Xinjiang area. A case-control study was conducted to explore the association between these two single-nucleotide polymorphisms and EH in a large sample size, including 941 EH subjects (309 Uygur, 264 Kazakh and 368 Han individuals) and 924 control subjects (300 Uygur, 275 Kazakh and 349 Han individuals). Univariate analysis showed that the rs5361 A/C polymorphism was significantly associated with EH in the Uygur (P=0.002) and Han (P=3.6 × 10(-7)) populations. The CC genotype of this SNP was present only in patients with EH in all of the three nationalities studied. Han individuals who carry the CC genotype of rs5361 were more susceptible to EH, according to the dominant models (P=1.13 × 10(-4), odds ratio=3.812, 95% confidence interval: 1.685-7.792), but there was no association of genotype with EH for the other ethnicities. No significant difference in rs5355 C/T polymorphism rate was found between the EH and control groups. Our results indicate that the common variant rs5361 is strongly associated with EH in Han individuals and weakly associated in Uygur individuals. The CC genotype of rs5361 might be an independent risk factor for EH among Uygur, Kazakh and Han individuals in the Xinjiang area.
