Abstract
INTRODUCTION Endothelial dysfunction is one of the most important factors implicated in the pathogenesis of coronary artery disease (CAD). The aim of this study was to investigate the association of the E-selectin gene (SELE) with CAD and CAD-related traits using tagging polymorphisms. MATERIAL AND METHODS A total of 379 Polish patients who had undergone angiography were included: 261 patients with angiographically documented CAD, 202 CAD patients without myocardial infarction (CAD/MI(-) group) and 59 patients with myocardial infarction (CAD/MI(+) group) as well as 118 healthy control subjects (non-CAD). Eight tagging single nucleotide polymorphisms (SNPs) in the SELE gene were selected using genotype data from HapMap. Genotyping was performed using PCR-RFLP and PCR-DHPLC methods. RESULTS The most common SELE haplotype in this analysis ([C;G;T;C;G;T], 31.2%) showed a negative association with myocardial infarction (MI) (CAD/MI(+) vs. non-CAD) under the additive (p = 0.001), dominant (p = 0.006) and recessive (p = 0.012) model. Two other haplotypes ([C;G;C;C;A;C], [C;A;C;A;G;T], 5.73% and 18.1%, respectively) were also negatively associated with MI under the additive and dominant model. We also found two haplotypes ([T;G;T;C;G;T], [C;G;C;C;A;T], 1.52% and 6.71%, respectively) associated with the risk for MI (CAD/MI(+) vs. CAD/MI(-)), acting in both additive (p = 0.04, p = 0.007, respectively) and dominant (p = 0.04, p = 0.004, respectively) manner. There was no association with either CAD/MI(-) or with severity of CAD expressed as the number of vessels involved. CONCLUSIONS Our results suggest that SELE is one of the independent genetic factors modifying the risk of myocardial infarction.

The Interaction of Selectins and PSGL-1 as a Key Component in Thrombus Formation and Cancer Progression. BIOMED RESEARCH INTERNATIONAL 2017; 2017:6138145. [PMID: 28680883 PMCID: PMC5478826 DOI: 10.1155/2017/6138145] [Citation(s) in RCA: 53] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/02/2017] [Revised: 04/12/2017] [Accepted: 04/23/2017] [Indexed: 12/11/2022]
Abstract
Cellular interaction is inevitable in the pathomechanism of human disease. Formation of heterotypic cellular aggregates, between distinct cells of hematopoietic and nonhematopoietic origin, may be involved in events leading to inflammation and the complex process of cancer progression. Among adhesion receptors, the family of selectins with their ligands have been considered as one of the major contributors to cell-cell interactions. Consequently, the inhibition of the interplay between selectins and their ligands may have potential therapeutic benefits. In this review, we focus on the current evidence on the selectins as crucial modulators of inflammatory, thrombotic, and malignant disorders. Knowing that there is promiscuity in selectin binding, we outline the importance of a key protein that serves as a ligand for all selectins. This dimeric mucin, the P-selectin glycoprotein ligand 1 (PSGL-1), has emerged as a major player in inflammation, thrombus, and cancer development. We discuss the interaction of PSGL-1 with various selectins in physiological and pathological processes with particular emphasis on mechanisms that lead to severe disease.

Abstract
BACKGROUND Atherosclerotic vascular disease represents a significant cause of morbidity and mortality in patients with end-stage renal disease (ESRD). The endothelium plays a crucial role in vascular inflammation. E-selectin is exclusively expressed on activated endothelial cells and is upregulated following an inflammatory response and oxidative stress, while serum pregnancy-associated plasma protein-A (PAPP-A) concentrations are related to the presence and stability of carotid atherosclerotic plaques. OBJECTIVE The aim of this study was to investigate whether there is an association between SELE rs5355C>T gene polymorphism, serum PAPP-A level and the presence of carotid atherosclerosis in ESRD patients. SUBJECTS AND METHODS Seventy subjects were recruited into this study; 40 ESRD patients [age (mean ± SD) 43.42 ± 13.94 years] and 30 age- and gender-matched healthy individuals assigned to the control group. Polymerase chain reaction-restriction fragment length polymorphism was performed for the analysis of SELE rs5355C>T gene polymorphism, while serum PAPP-A concentrations were measured using electro-chemiluminescence immunoassay. Routine laboratory tests were measured on an automated chemistry analyzer. Carotid ultrasonographic studies were performed by a bilateral high-resolution B-mode ultrasound. RESULTS There was no significant relationship between the SELE rs5355C>T gene polymorphism and ESRD incidence. Serum PAPP-A levels were significantly higher in ESRD patients compared with controls [median (interquartile range) 5.8 (5.1-11.6) and 5.1 (4.1-6.7), respectively; p = 0.005]. Serum PAPP-A correlated positively with urea, creatinine, systolic and diastolic blood pressure (DBP). Serum PAPP-A showed a statistically significant increase in SELE rs5355TT versus CC in both patients and controls. There was no association on comparing right intima-media thickness (IMT), left IMT, right cross-sectional area (CSA) and left CSA with the CC, CT and TT genotypes of SELE rs5355C>T. No correlation between serum PAPP-A with each of the above-mentioned carotid doppler findings was observed. There was a statistically significant increase in DBP in TT genotype carriers when compared with CC genotype carriers (p = 0.009). Serum PAPP-A levels were higher in hypertensive ESRD patients when compared with normotensive ESRD patients. There was a statistically significant decrease in high-density lipoprotein cholesterol (HDL-C) in TT genotype carriers when compared with CT genotype carriers in the whole study group (p = 0.003). Serum PAPP-A correlated negatively with HDL-C. CONCLUSION The lack of a direct association between SELE rs5355C>T gene polymorphism, serum PAPP-A level and IMT suggests that their hypothesized association with carotid atherosclerosis might reflect an indirect mechanism of SELE rs5355C>T gene polymorphism and serum PAPP-A with cardiovascular risk factors such as blood pressure and HDL-C rather than a direct effect on the vasculature.

Abstract
The C-type lectin E-selectin mediates the rolling of circulating leukocytes on vascular endothelial cells during the inflammatory process. In numerous studies, the S128R mutation of the E-selectin was associated with cardiovascular and autoimmune diseases. There is evidence that the S128R E-selectin mutation leads to a loss in ligand specificity, thus increasing leukocyte recruitment. Apart from the natural tetrasaccharide ligand sialyl Lewis(x) (sLe(x)), it has previously been proposed that non-fucosylated carbohydrates also bind to S128R E-selectin. To evaluate the therapeutic potential of the antagonism of the E-selectin mutant, ligand specificity was reinvestigated on a molecular basis. We determined the ligand specificity of wild-type and S128R E-selectin in a target-based competitive assay, a glycan array screen and cell-based binding assays under static and flow conditions. Regarding ligand-specificity, the binding properties of S128R E-selectin were identical to those of wt E-selectin, i.e., no mutant-specific binding of 3'-sialyl-N-acetyllactosamine, heparin, fetuin and K562 cells was observed. Additionally, the binding affinities of glycomimetic E-selectin antagonists were identical for wt and S128R E-selectin. Overall, the previous reports on carbohydrate ligand promiscuity of S128R E-selectin could not be confirmed.

Genetic score based on high-risk genetic polymorphisms and early onset of ischemic heart disease in an Italian cohort of ischemic patients. Thromb Res 2014; 133:804-10.

Abstract
Several single-nucleotide polymorphisms (SNPs) have been recognized as associated with ischemic heart disease (IHD) although the optimal set of risk genotypes has not be identified. This study aimed to examine whether identified high-risk SNPs are associated with early onset of IHD. In the GENOCOR study, 44 high-risk SNPs were genotyped in 114 patients with early onset of IHD (46.2 ± 5.1 years) and 384 patients with late onset of IHD (60.7 ± 5.9 years). The associations between individual SNPs and early onset IHD were assessed. A multilocus genetic risk score (GRS) for each associated risk genetic markers was constructed by summing the number of risk alleles. The SNPs significantly associated with IHD were: -482C>T of Apolipoprotein C III gene (ApoC3, p=0.02); 1171 5A>6A of Matrix metalloproteinase 3 stromelisine I gene (p=0.01); G98T of Selectin E gene (p=0.05); C/G of 9p21.3 locus (p=0.01). Likelihood ratio test showed a strong interaction for increasing risk of early IHD between the presence of ApoC3 and 9p21.3 locus with hypertriglyceridemia (p=0.0008, 0.0011) as well as between 9p21.3 locus and smoking (p=0.0010) after correction for multiple testing. The OR for premature IHD for GRS unit was 1.3 (95% CI 1.1-1.6, p=0.001). Patients in the top tertile of GRS were estimated to have a 3.2-fold (95% CI 1.5-6.8; p=0.001) increased risk of early IHD compared with those in the bottom tertile. The results show that currently identified high-risk SNPs confer an additive biomarker for cardiovascular events. GRS may provide important incremental information on the genetic component of IHD.

Abstract
Objective E-selectin (SELE) mediates the rolling and adhesion of leukocytes on activated endothelial cells and plays a critial role in the pathogenesis of coronary artery disease (CAD). Associatons between the A561C and G98T polymorphisms of the SELE gene and CAD risk were investigated broadly, but the results were inconsistent. In the present study, we performed a meta-analysis to systematically evaluate the associations between the two polymorphisms and the risk of CAD. Methods Comprehensive research was conducted to identify relevant studies. The fixed or random effect model was selected based on the heterogeneity among studies, which was evaluated with Q-test and Ι2. Meta-regression was used to explore the potential sources of between-study heterogeneity. Peters's linear regression test was used to estimate the publication bias. Results Overall, 24 articles involving 3694 cases and 3469 controls were included. After excluding articles deviating from Hardy–Weinberg equilibrium in controls and sensitive analysis, our meta-analysis showed a significant association between the A561C ploymprphism and CAD in dominant (OR = 1.84, 95% CI = 1.56–2.16) and codominant (OR = 1.74, 95% CI = 1.49–2.03) models. As for the G98T polymorphism, significantly increased CAD risk was observed in dominant (OR = 1.47, 95% CI = 1.16–1.87) and codominant (OR = 1.48, 95% CI = 1.18–1.86) models, but after subgroup analysis, the association was not significant among Caucasians in dominant (OR = 1.58, 95% CI = 0.73–3.41) and codominant (OR = 1.58, 95% CI = 0.79–3.20) models. Conclusions Despite some limitations, our meta-analysis suggested that the SELE gene polymorphisms (A561C, G98T) were significantly associated with increased risk of CAD. However, after subgroup analysis no significant association was found among Caucasians for the G98T polymorphism, which may be due to the small sample size and other confounding factors. Future investigations with multicenter, large-scale, and multi-ethnic groups are needed.

Abstract
BACKGROUND Recurrent aphthous stomatitis (RAS) is a common oral ulcerative condition. At ulcer sites vascular adhesion molecule-1 (VCAM-1), E-selectin and intercellular adhesion molecule-1 (ICAM-1) are strongly expressed on blood vessels, and ICAM-1 is expressed on keratinocytes. Expression of these molecules would promote leukocyte accumulation and invasion of the epithelium. Thus, polymorphisms in these candidate genes might contribute to RAS susceptibility. We investigated whether the inheritance of specific selectin, ICAM and VCAM gene polymorphisms is associated with RAS susceptibility. METHODS Ninety-six RAS cases and 153 controls were recruited from a Jordanian population. Blood was collected for hematological investigations and genotyping. Six SNPs were genotyped: E-selectin rs5361 and rs1805193, L-selectin, rs2205849, ICAM-1 rs5498, ICAM-5 rs885743 and VCAM-1 rs1800821. Association was determined using chi-square and binary logistic regression analysis after correcting for confounding factors. Linkage disequilibrium was determined using the EH program, and the Phase 2.1 program was used to construct and compare haplotypes between cases and controls. RESULTS There was a significant association of the A allele (Pcorr = 0.027), AA and AC genotypes (OR = 10.9 and 9.0, respectively) of the E-selectin rs5361 gene polymorphism and TAA haplotype (rs2205849, rs5361, and rs1805193, respectively; P = 0.03) with RAS. None of the other SNPs showed a significant association. CONCLUSIONS This is the first report to link inheritance of the A allele, AA and AC genotypes of the E-selectin rs5361 polymorphism with increased risk of RAS. Further studies in different patient cohorts are needed to confirm the association, and functional analyses might clarify the biological significance of the association.

Abstract
This study investigates the potential role of 17 chosen polymorphisms in 15 candidate genes and the risk of myocardial infarction in patients under 45 years of age. The study consists of 271 patients with myocardial infarction and 141 controls. The analysis of genetic polymorphisms was performed using the PCR–RFLP method. Of the chosen polymorphisms, two (Leu125Val PECAM1 and A1/A2 FVII) are related to myocardial infarction and two (C677T MTHFR and 5A/6A MMP3) to advanced stenosis in arterial vessels (> 75%). We also found that the frequency of some combinations among the analyzed genes and environmental factors varied between the patient and control groups.

Abstract
Endothelial dysfunction increases risk for type 2 diabetes. We examined whether variation in the gene for E-selectin (SELE), a biomarker of endothelial dysfunction, was associated with levels of E-selectin or diabetes quantitative traits (including fasting levels of insulin and hemoglobin A(1c)) in 719 nondiabetic participants of the Nurses' Health Study or with risk of diabetes in 602 incident (over 10 years of follow-up) cases and 655 control women matched for age, race, and fasting status. Variation in three single nucleotide polymorphisms previously associated with cardiovascular disease risk and having effects on E-selectin function, S128R, G98T, and L554F, was not significantly (p > 0.05) associated with levels of E-selectin or diabetes quantitative traits, or with risk of incident diabetes in the primary analysis. Among women with low levels of subclinical inflammation (C-reactive protein levels below the population median), S128R R allele carriers had a diabetes risk factor-adjusted relative risk of incident diabetes of 1.71 (95% confidence interval, 1.04 to 2.81) relative to those with the SS genotype. Apart from an association in this subgroup, we conclude that the E-selectin variants we examined are not important genetic risk factors for type 2 diabetes in women.

Abstract
The E-selectin gene, a member of the selectin superfamily of adhesion molecules, plays an important role in the pathogenesis of thrombovascular diseases. The present study was designed to investigate the potential relationship between E-selectin gene polymorphisms and ischemic stroke in a Chinese Han population. Three hundred fourteen ischemic stroke patients and 389 unrelated healthy controls were recruited for the study. Three single-nucleotide polymorphisms (SNPs)-rs1805193(G98T), rs5361(A561C), and rs5355(C1839T)-in the exon region of the E-selectin gene, were genotyped using a Multiplex SNaPshot sequencing assay. The data showed that the genotype and allele frequencies of G98T and C1839T SNP were similar in both ischemic stroke patients and the controls. In contrast, the frequency of both the AC genotype and the C allele of A561C was significantly higher in ischemic stroke patients than in healthy controls (P = 0.001, P < 0.001, respectively). After adjusting for other risk factors (such as hypertension, diabetes, tobacco smoking, and alcohol consumption), the E-selectin gene AC genotype and C allele of A561C were still associated with a risk of ischemic stroke (odds ratio [OR] = 2.73, 95% confidence interval (CI): 1.29-5.76, P = 0.008; OR = 2.80, 95% CI: 1.58-4.94, P < 0.001, respectively). Our current study demonstrates that the E-selectin SNP A561C is associated with increased risk for the development of ischemic stroke in this subset of the Han Chinese population.

Abstract
Inflammation is defined as the normal response of living tissue to injury or infection. It is important to emphasize two components of this definition. First, that inflammation is a normal response and, as such, is expected to occur when tissue is damaged. Infact, if injured tissue does not exhibit signs of inflammation this would be considered abnormal and wounds and infections would never heal without inflammation. Secondly, inflammation occurs in living tissue, hence there is need for an adequate blood supply to the tissues in order to exhibit an inflammatory response. The inflammatory response may be triggered by mechanical injury, chemical toxins, and invasion by microorganisms, and hypersensitivity reactions. Three major events occur during the inflammatory response: the blood supply to the affected area is increased substantially, capillary permeability is increased, and leucocytes migrate from the capillary vessels into the surrounding interstitial spaces to the site of inflammation or injury. The inflammatory response represents a complex biological and biochemical process involving cells of the immune system and a plethora of biological mediators. Cell-to-cell communication molecules such as cytokines play an extremely important role in mediating the process of inflammation. Inflammation and platelet activation are critical phenomena in the setting of acute coronary syndromes. An extensive exposition of this complex phenomenon is beyond the scope of this article (Rankin 2004).

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.

Abstract
Background E-selectin polymorphisms are an independent atherosclerosis and coronary artery disease (CAD) risk factor. This study aimed to investigate the link between the C1901T and G2692A E-selectin tagging SNPs and their haplotypes and the extent of coronary artery disease in Polish patients. Material/Methods For this study 321 patients were recruited CAD extent by coronary angiography and E selectin gene variant were investigated using HapMap, PCR/RFLP, multivariate logistic regression and haplotype analysis. Results Frequency distributions of the C1901T and G2692A polymorphisms were significantly different in CAD patients as compared to control subjects (p=0.037 and p=0.025, respectively). The C1901T polymorphism was found to be an independent genetic predictor of risk of CAD (OR=3.01) in a multivariate model adjusted for classic, environmental risk factors. The A-C and G-T haplotypes showed the strongest significant associations with CAD. The A-C haplotype proved to be significantly more common in controls (haplotype frequency 9.2%) than in CAD (5.7%, p=0.048); the G-T haplotype was not found among control subjects (0.0%) but was found in CAD (1.3%, p=0.0099). Conclusions Associations between the C1901T and G2692A E-selectin polymorphisms and CAD in the Polish population were found. Investigated variants correlated with the risk of coronary artery disease development but not with the extent of coronary artery vascular changes. In the haplotype analysis, 2 haplotypes influenced CAD – the A-C haplotype (7%) proved to exert a protective effect against CAD, while the effect of the less frequent G-T haplotype (1%) was associated with significant increase in CAD risk.

Abstract
INTRODUCTION Myocardial infarction is caused by the obstruction of an artery in places of atherosclerosis plaque rupture. Endothelial cells during their activation express chemoattractant and adhesion molecules whereas infiltrating inflammatory cells produce enzymes, predisposing a lesion to rupture. MATERIAL AND METHODS We investigated the correlation between polymorphisms in the human genes E-selectin (Ser128Arg), ICAM1 (K469E), OLR1 (K167N), MMP1 (1G/2G) and MMP3 (-1612 5A/6A) and the risk of MI in young Poles under 45 years. There was no significant difference in the frequency of single nucleotide polymorphism (SNP) of the studied genes E-selectin (Ser128Arg), ICAM1 (K469E), OLR1 (K167N) and MMP3 (-1612 5A/6A) between patients with MI and controls. RESULTS The analysis of the association of the 1G2G polymorphism with the risk of myocardial infarction indicated an odds ratio (OR) of 5.68 (95% confidence interval [95% CI] 2.60 to 12.36). Other factors associated with myocardial infarction were: smoking (OR 4.12; 95% CI 1.63-10.44), male sex (OR 16.02; 95% CI 5.90-43.46), hypercholesterolaemia (OR 2.74; 95% CI 1.29-5.83) and arterial hypertension (OR 4.56; 95% CI 1.66-14.47). CONCLUSIONS We found that only MMP1 1G/2G polymorphism is associated with myocardial infarction in the Polish population of individuals younger than 45 years. Clinical factors seemed to play a greater role in the analysed group.

Abstract
OBJECTIVE Hemorrhage continues to be a major problem after cardiac surgery despite the routine use of antifibrinolytic drugs, with striking inter-patient variability poorly explained by already known risk factors. The authors tested the hypothesis that genetic polymorphisms of inflammatory mediators and cellular adhesion molecules are associated with bleeding after cardiac surgery. DESIGN Prospective, observational study. SETTING Single, tertiary referral university heart center. PARTICIPANTS Adult patients undergoing aortocoronary surgery with cardiopulmonary bypass. INTERVENTIONS Patients (n = 759) had 10 mL of blood drawn preoperatively and genomic DNA isolated then genotyped for 17 polymorphisms in 7 candidate genes: tumor necrosis factor, interleukins 1beta and 6, interleukin 1 receptor antagonist, intercellular adhesion molecule-1 (ICAM-1), P-selectin and endothelial leucocyte adhesion molecule-1 (E-selectin). Multivariate analyses were used to relate clinical and genetic factors to bleeding and transfusion. MEASUREMENTS AND MAIN RESULTS The 98G/T polymorphism of the E-selectin gene was independently associated with bleeding after cardiac surgery (p = 0.002), after adjusting for significant clinical predictors (patient size and baseline hemoglobin concentration). There was a gene dose effect according to the number of minor alleles in the genotype; carriers of the minor allele bled 17% (GT) and 54% (TT) more than wild type (GG) genotypes, respectively (p = 0.01). Carriers of the minor allele also had longer activated partial thromboplastin times (p = 0.0023) and increased fresh frozen plasma transfusion (p = 0.03) compared with wild type. CONCLUSIONS The authors found a dose-related association between the 98T E-selectin polymorphism and bleeding after cardiac surgery, independent of and additive to standard clinical risk factors.

Abstract
BACKGROUND Our research group recently reported that aorto-radial (radial) and aorto-dorsalis-pedis (foot) pulse wave velocity (PWV) as proxies of arterial stiffness are substantially heritable in healthy youth. This article aimed at uncovering the genetic contributions of adhesion molecules, key members in the inflammatory process, to PWV in these young individuals. METHODS Radial and foot PWV were noninvasively measured with applanation tonometry in 702 black and white subjects (42% blacks, mean age 17.7 +/- 3.3 years) from the Georgia Cardio vascular Twin Study. Eight functional polymorphisms from genes for E-selectin (SELE), P-selectin (SELP), intercellular adhesion molecules-1 (ICAM1), and vascular cell adhesion molecules-1 (VCAM1) were genotyped. RESULTS Youth with Ser290Asn or Asn290Asn genotype (SELP) compared to those with Ser290Ser had an increase in both radial and foot PWV (6.61 +/- 0.07 vs. 6.41 +/- 0.05 m/s, p = .026; 7.22 +/- 0.05 vs. 7.04 +/- 0.04 m/s, p = .007). TT homozygotes of rs2244529 (SELP) had higher foot PWV (7.28 +/- 0.07 vs. 7.06 +/- 0.03 m/s, p = .002) than CT heterozygotes and CC homozygotes. There appeared to be a decrease in foot PWV in youth with the 241Arg allele (ICAM1) as compared to those without (6.96 +/- 0.08 vs. 7.14 +/- 0.03 m/s, p = .005). For the Asp693Asp (C to T) polymorphism (VCAM1), CC genotype had higher foot PWV than CT and TT genotypes (7.18 +/- 0.04 vs. 6.95 +/- 0.06 m/s, p < .0001). There was an epistatic interaction between Ser290Asn, Gly241Arg, and Asp693Asp on foot PWV (p = .017), explaining 3.6% variance of the foot PWV. CONCLUSION Genetic variation of adhesion molecules may be implicated in the development of arterial stiffness. Screening for adhesion molecule polymorphisms may help identify high-risk youth.

Abstract
Some host-related factors may predict the risk of metastasis after surgery of colorectal cancer (CRC). The endothelial adhesion molecule E-selectin is implicated in the metastatic spread of CRC. We postulated that some polymorphisms within the E-selectin gene, especially the S128R polymorphism, may increase the risk of metastases by facilitating adhesion of tumour cells to the endothelium. We collected blood samples for DNA extraction from 264 patients treated for stage II or III CRC and from 310 healthy controls in order to assess three polymorphisms within the E-selectin gene (S128R, G98T and L554F) and one within the P-selectin gene (V640L). Genotypes were analysed by the allelic discrimination TaqMan real-time PCR assay. The S128R polymorphism was detected in 59 patients (22.3%) and was strictly correlated with the G98T polymorphism. In multivariate analysis, the S128R polymorphism was associated with shorter event-free survival (EFS) and overall survival (OS) in the whole population (EFS: P=.003, HR 1.82, 95% CI 1.23-2.70; OS: P<10(-4), HR 4.31, 95% CI 2.46-10.99), in patients with stage II CRC(EFS: P=.04, HR 1.92, 95% CI 1.02-3.60; OS: P=.02, HR 4.44, 95% CI 1.16-17.03), and in patients with stage III CRC (EFS: P=.04, HR 1.68, 95% CI 1.01-2.80; OS: P=.001, HR 4.04, 95% CI 1.73-9.46). L554F and V640L polymorphisms had no prognostic value. The S128R polymorphism is a constitutional factor associated with a higher risk of relapse and death in patients treated for CRC. This polymorphism detection may permit better selection of patients suitable for adjuvant therapy, especially among those with stage II disease.

Abstract
BACKGROUND Ulcerative colitis (UC) and Crohn's disease (CD) are chronic intestinal disorders characterized by immune dysregulation and leukocytes recruitment into gastrointestinal tract. Cell adhesion molecules (CAM) mediate the extravasation of leukocytes and their accumulation in inflamed intestinal mucosa. Recently, CAM genes have been implicated in determining susceptibility to UC and CD. We investigate seven mutations in CAM: G241R and K469E in ICAM-1, V125L in PECAM-1, G98T, S128R, and L554F in E-selectin and F206L in L-selectin in 197 Tunisian patients (73 with UC and 124 with CD) and 194 controls. These polymorphisms were detected by polymerase chain reaction sequence-specific primers and restriction enzyme analysis. RESULTS A significant increase in allele frequencies of 206L of L-selectin and the associated genotype F/L was observed in both patients with UC and CD compared with controls. Subgroup analysis showed that the L206 allele and F/L206 genotype frequencies were significantly increased in UC patients with left-sided type; whereas, the F/L206 genotype was significant in CD patients with ileocolonic location and stricturing behavior compared with controls. No significant differences in allele or genotype frequencies were observed for ICAM-1 K469E, E-selectin, and PECAM-1 polymorphisms between UC patients, CD patients, and controls. CONCLUSION We found an association of inflammatory bowel disease with allele L206 of L-selectin gene, whereas genotype L/F was associated with a subgroup of UC (left-sided type) and CD patients with more extensive location of disease and stricturing behavior. However, further studies are needed to confirm our findings.

Abstract
Oxidative stress and inflammation are accepted as major factors in the pathogenesis of atherosclerosis, but how they interact to produce a plaque has not been delineated clearly. Recent data suggest that oxidized lipids may act in part by regulating production of chemokines and chemokine receptors, which in turn, may direct monocytes and other blood leukocytes to the vessel wall, where they may interact with endothelial cells and smooth muscle cells. The receptors may act at the level of recruitment, retention, and egress, not only through classic, chemotactic mechanisms but also through direct, intercellular adhesion. The results suggest a coordinated mechanism for inflammatory cell accumulation in plaque and identify novel targets, such as CCR2 and CX3CR1, for potential drug development in coronary artery disease.

Abstract
BACKGROUND Studies have shown an association between altered expression of selectins and premature birth, early sepsis and bronchopulmonary dysplasia. AIM To investigate the possible link between functional polymorphisms of the E-, P- and L-selectin genes and perinatal morbidity. METHODS We compared the genotype distribution of the E-selectin Ser128Arg, P-selectin Thr715Pro and L-selectin Pro213Ser polymorphisms in 125 low-birthweight singleton infants with those of 156 healthy term neonates. We also analysed the association of genotype with risk of sepsis and bronchopulmonary dysplasia. RESULTS We found no association between E-selectin or P-selectin polymorphisms and premature birth, nor did we find any association between E-selectin or P-selectin and early postnatal sepsis or bronchopulmonary dysplasia. Carriers of the 213Ser L-selectin allele were found to be more prevalent in low-birthweight infants, particularly in those with bronchopulmonary dysplasia. We found no association between the L-selectin polymorphism and early postnatal sepsis. CONCLUSION Our results underline the importance of L-selectin in perinatal pathology, but further studies are needed to evaluate the alteration of L-selectin levels in carriers of the 213Ser allele and their possible contribution to premature birth and bronchopulmonary dysplasia.

Abstract
Familial Hypercholesterolemia (FH) is a genetic disorder characterized by high low-density lipoprotein cholesterol (LDL-C) concentrations that frequently gives rise to premature coronary artery disease. The clinical expression of FH is highly variable, even in patients carrying the same LDL receptor gene mutation. This variability may be due to environmental and other genetic factors. We investigated the effect of APOCIII T1100C, FV Gln506Arg, ADRB2 Glu27Gln, SELE Ser128Arg, SELE Leu554Phe, and ENaCa Ala663Thr polymorphisms on the HDL-C variations in 84 patients with FH. For ApoCIII T1100C, subjects with the TT genotype presented higher HDL-C levels than the other genotype groups (p = 0.046). Similarly the presence of the Gln allele in ADRB2 27 Glu/Gln heterozygotes and ADRB2 27 Gln/Gln homozygotes was associated with higher HDL-C levels (p = 0.014). Among the other polymorphisms tested, none of them were associated with variations in HDL-C levels. The influence of each polymorphism on lipid concentrations was evaluated with linear regression analyses after adjustment for age and sex. Among the variables studied including total cholesterol, LDL-C, high-density lipoprotein (HDL)-C, triglycerides, apolipoprotein A (Apo-A) and B (Apo-B), and lipoprotein alpha (LP alpha), HDL-C concentration was significantly different in models applied for polymorphisms ApoCIII T1100C, FV Gln506Arg, and ADRB2 Glu27Gln (p = 0.01, p = 0.018, p = 0.04, respectively). These results suggest that HDL-C levels in FH heterozygotes may be affected by several different genetic variants.

Abstract
BACKGROUND The inflammatory response triggered by cardiac surgery with cardiopulmonary bypass (CPB) is a primary mechanism in the pathogenesis of postoperative myocardial infarction (PMI), a multifactorial disorder with significant inter-patient variability poorly predicted by clinical and procedural factors. We tested the hypothesis that candidate gene polymorphisms in inflammatory pathways contribute to risk of PMI after cardiac surgery. METHODS AND RESULTS We genotyped 48 polymorphisms from 23 candidate genes in a prospective cohort of 434 patients undergoing elective cardiac surgery with CPB. PMI was defined as creatine kinase-MB isoenzyme level > or = 10x upper limit of normal at 24 hours postoperatively. A 2-step analysis strategy was used: marker selection, followed by model building. To minimize false-positive associations, we adjusted for multiple testing by permutation analysis, Bonferroni correction, and controlling the false discovery rate; 52 patients (12%) experienced PMI. After adjusting for multiple comparisons and clinical risk factors, 3 polymorphisms were found to be independent predictors of PMI (adjusted P<0.05; false discovery rate <10%). These gene variants encode the proinflammatory cytokine interleukin 6 (IL6 -572G>C; odds ratio [OR], 2.47), and 2 adhesion molecules: intercellular adhesion molecule-1 (ICAM1 Lys469Glu; OR, 1.88), and E-selectin (SELE 98G>T; OR, 0.16). The inclusion of genotypic information from these polymorphisms improved prediction models for PMI based on traditional risk factors alone (C-statistic 0.764 versus 0.703). CONCLUSIONS Functional genetic variants in cytokine and leukocyte-endothelial interaction pathways are independently associated with severity of myonecrosis after cardiac surgery. This may aid in preoperative identification of high-risk cardiac surgical patients and development of novel cardioprotective strategies.

Abstract
BACKGROUND E-selectin is a cell surface glycoprotein that mediates the adhesion of leucocytes to vessels endothelium, an important early step in the atherosclerotic process. End-stage renal disease (ESRD) is a highly atherogenic disease but it is unknown whether genetic polymorphism(s) in the E-selectin gene plays a role in the severity of arterial damage in this condition. Method. In this study, we tested whether the Leu554Phe variant in the E-selectin gene is linked to carotid atherosclerosis in 134 well-characterized ESRD patients. The frequency of this polymorphism was also measured in a population sample of the same geographical area. RESULTS A total of 84% patients had the CC genotype, 13% had the CT genotype, 3% had the TT genotype and this distribution did not differ from that in the control population. Intima-media thickness (IMT) (P = 0.01) and cross-sectional area (P = 0.02) were significantly higher in patients with the T-allele than in those without this allele. Furthermore, the degree of carotid stenosis was significantly higher (P = 0.02) in patients with T-allele than in CC patients. On multivariate analyses including the traditional and non-traditional risk factors, the Leu554Phe polymorphism was confirmed as an independent correlate of IMT (P = 0.02), cross-sectional area (P = 0.03) and carotid stenosis (P = 0.02). CONCLUSION In ESRD, the Leu554Phe polymorphism of E-selectin gene is associated with the severity of carotid atherosclerosis, suggesting that genetically-determined alterations in the E-selectin molecule may render ESRD patients with this gene variant particularly susceptible to the detrimental effects of inflammation on the arterial wall.

Abstract
Circulating concentrations of inflammatory markers predict cardiovascular disease (CVD) risk and are closely associated with obesity. However, little is known concerning genetic influences on serum levels of inflammatory markers. In this study, we estimated the heritability (h2) of soluble cellular adhesion molecule (sCAM) concentrations and examined the correlational architecture between different sCAMs. The study population included 234 men and 270 women aged 18-76 years, belonging to 121 families participating in the Fels Longitudinal Study. Serum levels of soluble intercellular adhesion molecule-1 (sICAM-1), vascular cell adhesion molecule-1 (sVCAM-1), E-selectin (sESEL-1) and P-selectin (sPSEL-1) were assayed using commercially available kits. A variance components-based maximum likelihood method was used to estimate the h2 of the different serum inflammatory markers while simultaneously adjusting for the effects of known CVD risk factors, such as age and smoking. Additionally, we used bivariate extensions of these methods to estimate genetic and random environmental correlations among sCAMs. Levels of sCAMs were significantly heritable: h2=0.24+/-0.10 for sICAM-1, h2=0.22+/-0.10 for sVCAM-1, h2=0.50+/-0.11 for sESEL-1, and h2=0.46+/-0.10 for sPSEL-1. In addition, a significant genetic correlation (rho(G)=0.63) was found between sICAM-1 and sVCAM-1 indicating some degree of shared genetic control. In the Fels Longitudinal Study, the levels of four sCAMs are significantly influenced by genetic effects, and sICAM-1 shares a common genetic background with sVCAM-1.

Abstract
BACKGROUND The E-selectin mediates the interaction of activated endothelial cells with leukocytes and plays a fundamental role in the pathogenesis of coronary atherosclerosis. It has been suggested that a S/R (Ser128Arg) polymorphism of E-selectin might be associated with the predisposition to coronary artery disease (CAD). Our purpose was to determine whether this S/R polymorphism influences the risk of CAD in Chinese patients. METHODS AND RESULTS We studied the human E-selectin gene polymorphism in a Chinese population by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). This polymorphism was determined in 248 CAD patients and in 256 control subjects. Frequencies of the SS, SR, and RR genotypes were found as 86.7%, 13.3%, and 0.0% in CAD patients and 93.8%, 6.2%, and 0.0% in control subjects, respectively. Frequency of the R allele was higher among CAD patients compared to controls(6.7% vs. 3.1%). However, either the genotype or the allele distribution of Ser128Arg polymorphism of E-selectin was statistically significantly different between the two groups (P<0.05). The odds ratio for the risk of CAD associated with the R allele was 2.21 (CI95%:1.20-4.07). CONCLUSIONS These results suggest that the SR genotype of the E-selectin gene polymorphism in codon 128 is a genetic factor that may determine an individual's susceptibility for CAD in Chinese.

Abstract
One early phase of atherosclerosis involves the recruitment of inflammatory cells from the circulation and their transendothelial migration. This process is predominantly mediated by cellular adhesion molecules, which are expressed on the vascular endothelium and on circulating leukocytes in response to several inflammatory stimuli. Selectins (P, E and L) and their ligands (mainly P-selectin ligand) are involved in the rolling and tethering of leukocytes on the vascular wall. Intercellular adhesion molecules (ICAMs) and vascular cell adhesion molecules (VCAM-1), as well as some of the integrins, induce firm adhesion of inflammatory cells at the vascular surface, whereas platelet endothelial cellular adhesion molecules (PECAM-1) are involved in extravasation of cells from the blood compartment into the vessel and underlying tissue. For most of the cellular adhesion molecules, except integrins, soluble forms have been identified in the circulation although their origins are not fully understood. Several lines of evidence support a crucial role of adhesion molecules in the development of atherosclerosis and plaque instability. Expression of VCAM-1, ICAM-1 and L-selectin has been consistently observed in atherosclerotic plaques. There is accumulating evidence from prospective studies for a predictive role of elevated circulating levels of sICAM-1 in initially healthy people, and of sVCAM-1 in patients at high risk or with overt CAD. A large number of common polymorphisms has been identified in the genes encoding the different adhesion molecules, but studies investigating their relationship either with soluble forms or with CAD are still sparse and often based on small samples. Further research is needed to firmly establish the potential clinical and therapeutic utilities of (soluble) adhesion molecules, but results in both fields hold the promise that in future, adhesion molecules might add information for clinical risk prediction and serve as therapeutic targets.

Abstract
BACKGROUND Associations between circulating concentrations of E-selectin, blood pressure and obesity, and between the Leu554Phe (L/F554) polymorphism and blood pressure have been documented. OBJECTIVES To investigate how the E-selectin L/F554 polymorphism is involved in longitudinal blood pressure changes, and how this polymorphism interacts with body mass index (BMI) on blood pressure. DESIGN AND PARTICIPANTS For this study, 478 men and 546 women were selected from the Stanislas cohort, a French longitudinal study of volunteers for a free health check-up. These individuals underwent two examinations (t(0) and t(+5)) and were not taking medication that can affect blood pressure. RESULTS At t(0), no relationship was observed between L/F554 polymorphism and blood pressure. However at t(+5), systolic blood pressure (SBP) was greater in individuals carrying the F allele, and the L/F554 polymorphism was associated with SBP in interaction with BMI (P < 0.001 in men and P < 0.05 for women). There was a steeper increase in SBP with BMI greater than 25 kg/m2 in carriers of the F allele than in LL homozygotes. Similar results were observed for diastolic blood pressure in men (P = 0.0103). CONCLUSION These results suggest a BMI-specific effect of L/F554 polymorphism of the E-selectin gene on blood pressure, and strengthen the hypothesis that E-selectin is implicated in hypertension.

Abstract
OBJECTIVE Polymorphisms found in genes encoding adhesion molecules have been reported to be associated with atherosclerosis. We investigated the Ser128Arg polymorphism in the E-selectin gene in Japanese patients with myocardial infarction and its functional significance. METHODS AND RESULTS Results from 135 patients with myocardial infarction and 327 control subjects revealed that the frequency of Arg128-positive was significantly higher in the patients than in controls (12.6% versus 6.7%; odds ratio, 2.0; 95% CI, 1.04 to 3.85), indicating that the Ser128Arg polymorphism was associated with myocardial infarction. We then generated a recombinant E-selectin adenovirus carrying a mutation (AdS128R-E) and compared it with its wild-type counterpart by evaluating the adhesion characteristics of transduced human umbilical vein endothelial cells under flow. AdS128R-E-transduced human umbilical vein endothelial cells supported significantly more rolling and adhesion of neutrophils and mononuclear cells compared with human umbilical vein endothelial cells transduced with AdWT-E (P<0.001) and also exhibited significantly greater levels of phosphorylation of extracellular signal regulated kinase 1 and 2 and p38 mitogen-activated protein kinase, suggesting that an altered endothelial signaling pathway is associated with this polymorphism. CONCLUSIONS Our results suggest that the E-selectin Ser128Arg polymorphism can functionally alter leukocyte-endothelial interactions as well as biochemical and biological consequences, which may account for the pathogenesis of myocardial infarction.

Abstract
Both inflammation and genetics play an important role in the pathogenesis of atherosclerosis and coronary artery disease. Epidemiological studies have investigated the association between coronary artery disease (CAD) and gene polymorphisms of the inflammatory molecules tumor necrosis factors (TNF) alpha and beta, transforming growth factors (TGF) beta-1 and beta-2, interleukin (IL)-1 and its receptor antagonist (IL-1ra), CD14 (the receptor for lipopolysaccharide), P- and E-selectins, and platelet endothelial cell adhesion molecule (PECAM)-1. Current evidence suggests that the TNF polymorphisms explored so far are not linked to CAD. The majority of studies conducted showed no significant association between TGFbeta-1 and coronary atherosclerosis, but the data currently available are somewhat controversial. Some polymorphisms may increase the risk of myocardial infarction (MI) within specific ethnic groups or in certain populations. The association between the IL-1 system and atherosclerosis is complex and may vary as a result of a number of factors, such as stage of disease, clinical phenotype, and possibly population characteristics. The E-selectin gene (SELE) Arg128, 98T, and Phe554 alleles may increase the risk of atherosclerosis, but not necessarily the risk of MI. This association seems to be more pronounced in younger patients. The PECAM1 Leu125Val and Ser563Asn polymorphisms may increase the risk of atherosclerosis but not necessarily of MI. This association may be especially important in patients with a low risk for developing atherosclerosis. Current data indicate that screening for CD14-260C/T genotypes is unlikely to be a useful tool for risk assessment and it remains unclear whether CD14 polymorphisms significantly increase the risk of MI. The associations between candidate gene polymorphisms and CAD are complex as a consequence of pleiotropy, variations with age, selection due to the high lethality of the disease, and interactions with other genes and environmental factors. Nonetheless, although the current data is preliminary and partly conflicting, it does provide some evidence that alterations in the genetics of the inflammatory system may modify the risk of CAD.

Abstract
BACKGROUND The intercellular adhesion molecule-1 (ICAM-1) mediates the interaction of activated endothelial cells with leukocytes and plays a fundamental role in the pathogenesis of coronary atherosclerosis. ICAM-1 single-base C/T polymorphism, which determines an amino acid substitution in the ICAM-1 protein in exon 6 codon 469, has been described. Our purpose was to determine whether this C/T polymorphism influences the risk of coronary heart disease (CHD) and myocardial infarction (MI) in humans. METHODS AND RESULTS We enrolled 349 patients with angiographically documented CHD, including a sub-group of 179 patients with acute or chronic MI. The control group consisted of 213 patients with normal left ventricular function and no documented evidence of CHD. All patients and controls were Germans genotyped by polymerase chain reaction and allele-specific oligonucleotide techniques for the ICAM-1 polymorphism. In the patients with CHD and MI the frequencies of the T genotype (TT+TC) were significantly higher than the CC genotype compared to the control subjects (P<0.001). With the additional use of multivariable logistic regression analysis for CHD (TT+TC versus CC; P=0.011, odds ratio 2.21, 95% CI 1.20-4.07), we found a significant association between CHD and MI and the TT and TC genotype of the ICAM-1 gene polymorphism. CONCLUSIONS These results suggest that the TT and TC genotype of the ICAM-1 gene polymorphism in codon 469 is a genetic factor that may determine an individual's susceptibility for CHD and MI.

Abstract
OBJECTIVES Coronary angioplasty remains plagued by the problem of restenosis. Genetic polymorphisms may contribute to the development of restenosis by mediating exaggerated inflammatory responses of the endothelium to angioplasty-induced injury. BACKGROUND The serine (Ser)-128-arginine (Arg) gene polymorphism of E-selectin has been implicated in the pathogenesis of coronary artery disease (CAD). We sought to explore whether allelic variants relate to post-angioplasty restenosis. METHODS The 128Arg allele was analyzed by PCR in 101 (derivation study, age 54+/-1 years, all mean+/-S.E.M.) and 92 (validation study, age 62+/-1 years) patients with CAD who underwent successful angioplasty. RESULTS Restenosis, defined as >50% luminal diameter reduction at the target lesion at follow-up angiography, was found in 54/101 (53%) and 43/92 (47%) patients during follow-up. The 128Arg allele frequency in the derivation study was 10.39% and was 11.96% in the validation study. The 128Arg allele was more prevalent in the restenosis groups (14.81% and 17.44%, respectively) than in the restenosis-free groups (5.32% and 7.14%, respectively, p=0.027 and p=0.031). In multivariate logistic regression, the 128Arg allele emerged as a predictor of restenosis in both studies (p<0.05). There were no differences in the level of soluble E-selectin according to genotype, gender, age (p>0.20), and between patients with restenosis and those without (43.8+/-3.2 vs. 47.4+/-3.1 ng/ml, p>0.20). CONCLUSIONS The 128Arg allele of E-selectin may be related to increased endothelial responses to injury, thereby potentially serving as a risk factor for post-angioplasty restenosis in patients with CAD.The development of restenosis remains a problem in patients with CAD. The Ser128Arg polymorphism of E-selectin was analyzed in 101 (derivation) and 92 (validation) CAD patients. Patients with restenosis (54/101 and 43/92) had a higher frequency of the 128Arg allele (14.81 and 17.44%) than those without (5.32%, p=0.027 and 7.14%, p=0.031). In logistic regression, the 128Arg allele emerged as a predictor of restenosis in both studies (p<0.05). The E-selectin 128Arg allele may serve as a risk factor for the development of restenosis.

Abstract
AIMS Leucocyte adhesion to the diabetic retinal vasculature has been implicated in the pathogenesis of diabetic retinopathy. We evaluated the relationship between genetic polymorphisms in leucocyte and endothelial cell adhesion molecules and diabetic retinopathy in Type 2 diabetes mellitus. METHODS We determined ICAM-1, platelet endothelial cell adhesion molecule-1 (PECAM-1), and leucocyte endothelial adhesion molecule-1 (LECAM-1) genotypes in 81 patients with and 50 without diabetic retinopathy. RESULTS The frequency of ICAM-1 469KK genotype and K allele were significantly higher in the patients with diabetic retinopathy than in those without retinopathy (genotype 42% vs. 20%, chi2 = 6.70, P = 0.035; allele 66% vs. 50%, chi2 = 6.49, P = 0.011). With regard to the PECAM-1 V125L and LECAM-1 P213S polymorphisms, there were no significant associations between the distribution of genotypes or allele frequencies and the presence of diabetic retinopathy. Independent of other risk factors, the ICAM-1 469KK genotype was associated with a 3.51-fold increased risk for retinopathy. CONCLUSIONS These data suggest that the ICAM-1 469KK genotype could be a genetic risk factor for retinopathy in Type 2 diabetes mellitus.

Abstract
E-selectin mediates the rolling of circulating leukocytes on vascular endothelial cells. A polymorphism, in which serine is substituted for arginine at position 128 (S128R) in the EGF domain, has been associated with both early-onset atherosclerosis and SLE. We investigated whether the substitution alters the ligand-binding properties of E-selectin under shear flow by studying the capacity of Chinese hamster ovary cell transfectants expressing wild type (WT) or S128R E-selectin to support interactions of neutrophils, K562 cells or HL60 cells. We initially chose to study non-fucosylated K562 cells. No interactions were observed on WT E-selectin, whereas S128R supported a transient tethering interaction of K562 cells, which was resistant to digestion with either neuraminidase or O-sialoglycoprotein endopeptidase, and, in turn, could result in firm adhesion in the presence of a beta2-integrin. HL60 cells exhibited increased rolling on S128R E-selectin. Although neuraminidase treatment inhibited all HL60 interactions with WT E-selectin, it unmasked transient tethers on S128R. We further observed that S128R recruited significantly more neutrophils than WT E-selectin, without affecting neutrophil rolling velocity. This polymorphism may therefore amplify leukocyte-endothelial cell interactions and may be a factor linking the S128R polymorphism to vascular disease.

Abstract
An increased expression of E-selectin has been observed in the arterial endothelium interacting with lymphocytes and macrophages in human atherosclerotic lesions. We examined whether a polymorphism in the E-selectin gene, due to a G to T mutation (G98T) in the untranslated region of exon 2, was associated with premature coronary artery disease (CAD). Other lipid and nonlipid risk factors including a Ser to Arg (S128R) substitution in the E-selectin gene were also assessed. In patients with premature CAD (men < or = 45 years old and women < or =55 years old, N = 51) who underwent an elective diagnostic coronary arteriography, the frequency of the mutation was significantly higher than in controls (N = 50, 0.22 vs. 0.10, p = 0.024). After controlling for other CAD risk factors (plasma total cholesterol, triglyceride, LDL-apolipoprotein B. cigarette smoking and the S128R mutation) by multiple logistic analysis, the G98T mutation in the E-selectin gene was still a significant predictor of premature CAD [p = 0.022, odds ratio (95%, CI)= 3.58 (1.20-10.67)].
