Abstract
OBJECTIVES Patients undergoing cardiac surgery develop post-sternotomy pain syndrome. The aim of this study was evaluation of the influence of CYP2C9, PTGS-1 and PTGS-2 genes polymorphisms on the efficacy and safety of postoperative analgesia with ketoprofen in patients with coronary artery disease after cardiac surgery. METHODS The study included 90 patients undergoing cardiac surgery. A real-time polymerase chain reaction was used for the detection of single nucleotide polymorphisms (SNP). Pain intensity was measured by the Numeric Rating Scale (NRS). Dyspeptic symptoms were evaluated using the Gastrointestinal Symptom Rating Scale (GSRS). Acute kidney injury (AKI) was determined by Kidney Disease Improving Global Outcomes criteria. RESULTS Pain intensity by the NRS score was significantly higher in patients with CYP2C9*3 АA genotype compared to АC genotype: 7 [1,10] and 6 [2,7] (p=0.003); 7 [1,10] and 6 [2,7] (p=0.04); 6 [0; 10] and 5 [2,6] (p=0.04); 5 [0; 8] and 3 [0; 8] (p=0.02), on days 1, 2, 3 and 5 in the postoperative period, respectively. GSRS score was higher in patients with CYP2C9*2 CT genotype compared to CС genotype: 19 [15; 42] and 18 [15,36] (p=0.04), respectively. There were no significant differences in the pain intensity, dyspepsia severity and AKI frequency in patients with homozygous and heterozygous genotypes for PTGS-1 rs10306135, PTGS-1 rs12353214, PTGS-2 rs20417. CONCLUSIONS CYP2C9*3 and CYP2C9*2 gene polymorphisms may affect efficacy and safety of postoperative analgesia with ketoprofen in patients with coronary artery disease after cardiac surgery.

Abstract
BACKGROUND AND PURPOSE Cross-reactive hypersensitivity to nonsteroidal anti-inflammatory drugs (NSAIDs) is a relatively common adverse drug event caused by two or more chemically unrelated drugs and that is attributed to inhibition of the COX activity, particularly COX-1. Several studies investigated variations in the genes coding for COX enzymes as potential risk factors. However, these studies only interrogated a few single nucleotide variations (SNVs), leaving untested most of the gene sequence. EXPERIMENTAL APPROACH In this study, we analysed the whole sequence of the prostaglandin-endoperoxide synthase genes, PTGS1 and PTGS2, including all exons, exon-intron boundaries and both the 5' and 3' flanking regions in patients with cross-reactive hypersensitivity to NSAIDs and healthy controls. After sequencing analysis in 100 case-control pairs, we replicated the findings in 540 case-control pairs. Also, we analysed copy number variations for both PTGS genes. KEY RESULTS The most salient finding was the presence of two PTGS1 single nucleotide variations, which are significantly more frequent in patients than in control subjects. Patients carrying these single nucleotide variations displayed a significantly and markedly lower COX-1 activity as compared to non-carriers for both heterozygous and homozygous patients. CONCLUSION AND IMPLICATIONS Although the risk single nucleotide variations are present in a small proportion of patients, the strong association observed and the functional effect of these single nucleotide variations raise the hypothesis of genetic susceptibility to develop cross-reactive NSAID hypersensitivity in individuals with an impairment in COX-1 enzyme activity.

Abstract
Purpose Cyclooxygenase (COX) is the main pharmacodynamic target of nonsteroidal anti-inflammatory drugs (NSAIDs). We investigated the inhibitory effects on COX-2 after NSAIDs administration using a lipopolysaccharide (LPS)-derived COX-2 induction model in whole blood, according to the genotypes of COX-2 single-nucleotide polymorphisms (SNPs). Patients and methods Seven genotypes of COX-2 SNPs were selected from public databases and analyzed in 324 healthy subjects. Two genotypes showing a high percentage of variability were selected. A clinical trial examining pharmacodynamics according to the genotype of two SNPs (rs5275 and rs689466) was conducted. Twenty subjects were administered a single oral dose of 200 mg of celecoxib, and pharmacokinetic and pharmacodynamic analyses were performed. Results In the analysis of the pharmacokinetic parameters, significant differences in drug exposure were not investigated for each SNP genotype. The pharmacodynamic analysis revealed that the maximum effect of COX-2 inhibition was achieved at 2.0 hours for all genotypes of COX-2 SNPs after a single oral administration of 200 mg celecoxib. The inhibitory effects according to the genotype of COX-2 SNPs were investigated, and the area under the effect curve of the rs689466 GG genotype was significantly lower than that for the AA or AG genotype. Conclusion Our results demonstrated that inhibitory effects of celecoxib on COX-2 induction were different according to the genotype of COX-2 SNPs. In the present study, rs689466 is responsible for the variability of the response to celecoxib, suggesting that a subject with the GG genotype of rs689466 would be more responsive to celecoxib in terms of COX-2 inhibition.

Abstract
Background The aim of this study was to evaluate the relationships of CYP2C9 and COX-2 genetic polymorphisms with therapeutic efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) in treatment of ankylosing spondylitis (AS). Material/Methods We enrolled 130 AS inpatients and outpatients in the Arthritis and Rheumatism Department of Peking University First Hospital and 106 healthy people getting routine check-ups between September 2013 and July 2014. CYP2C9 and COX-2 genetic polymorphisms were detected by PCR-RFLP. All AS patients underwent medical treatment and 12-week follow-up treatment. Score differences of BASDAI, ASAS20, ASAS50, and ASAS70 for AS patients with different genotypes before and after treatment were compared. Results In terms of COX-2-1290A/G and -1195G/A gene polymorphism genotype and allele frequency, the case group and control group were obviously different (all P<0.05), but CYP2C9*3 polymorphism genotype and allele frequency were not statistically different between the 2 groups (P>0.05). AS patients had improved BASDAI, ASAS20, ASAS50, and ASAS70 scores after they received NSAID treatment (all P<0.05). Furthermore, the efficacy of NSAID in treatment of AS and COX-2 gene −1290A/G and −1195G/A polymorphism were associated (all P<0.05), but it is not associated with CYP2C9 *3 polymorphism (all P>0.05). Conclusions COX-2-1290A/G and -1195G/A polymorphism may increase AS risk and they both can be considered as biological indicators for prediction of efficacy of NSAIDs in treatment of AS.

Abstract
Diisocyanates are the most common cause of occupational asthma, but risk factors are not well defined. A case-control study was conducted to investigate whether genetic variants in inflammatory response genes (TNFα, IL1α, IL1β, IL1RN, IL10, TGFB1, ADAM33, ALOX-5, PTGS1, PTGS2 and NAG-1/GDF15) are associated with increased susceptibility to diisocyanate asthma (DA). These genes were selected based on their role in asthmatic inflammatory processes and previously reported associations with asthma phenotypes. The main study population consisted of 237 Caucasian French Canadians from among a larger sample of 280 diisocyanate-exposed workers in two groups: workers with specific inhalation challenge (SIC) confirmed DA (DA(+), n = 95) and asymptomatic exposed workers (AW, n = 142). Genotyping was performed on genomic DNA, using a 5' nuclease PCR assay. After adjusting for potentially confounding variables of age, smoking status and duration of exposure, the PTGS1 rs5788 and TGFB1 rs1800469 single nucleotide polymorphisms (SNP) showed a protective effect under a dominant model (OR = 0.38; 95% CI = 0.17, 0.89 and OR = 0.38; 95% CI = 0.18, 0.74, respectively) while the TNFα rs1800629 SNP was associated with an increased risk of DA (OR = 2.08; 95% CI = 1.03, 4.17). Additionally, the PTGS2 rs20417 variant showed an association with increased risk of DA in a recessive genetic model (OR = 6.40; 95% CI = 1.06, 38.75). These results suggest that genetic variations in TNFα, TGFB1, PTGS1 and PTGS2 genes contribute to DA susceptibility.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are a chemically heterogeneous group of compounds that provide unmistakable and significant health benefits in the treatment of pain and inflammation. They include traditional NSAIDs (tNSAIDs), which act by inhibiting both cyclooxygenase (COX)-1 and COX-2 and selective COX-2 inhibitors (coxibs). The development of biomarkers predictive of the impact of NSAIDs on COX-1 and COX-2 activities in vitro, ex vivo and in vivo has been essential to read out the clinical consequences of selective and non-selective inhibition of COX isozymes in human beings. The analgesic and anti-inflammatory effects of NSAIDs are COX-2-dependent effects, unrelated to COX-2 selectivity. The intensity and duration of these effects are influenced by dose and half-life of the NSAID. However, the inhibition of COX-1 in cells of the gastrointestinal (GI) system and COX-2 in vascular cells translates into increased risk of serious GI adverse events and atherothrombosis and hypertension, respectively. The COX-2 selectivity of NSAIDs can predict, at least in part, the GI toxicity. In contrast, the CV effects are largely COX-2-dependent effects, unrelated to COX-2 selectivity but are dose dependent. The reduction in the dose is recommended and presumably will limit the number of patients exposed to a CV or a GI hazard by NSAIDs and coxibs. It will not, however, eliminate the risk on an individual level because there is a marked variability in how different people react to these drugs, based on their genetic background. The challenge of the next future will be to develop biomarkers useful to identify the individuals who react abnormally to COX inhibition.

Abstract
Cyclooxygenase two (COX-2) is an important enzyme metabolizing arachidonic acid. In contrast to constitutive cyclooxygenase one (COX-1), COX-2 is induced by proinflammatory factors. Polymorphism -765 G/C in COX-2-encoding gene promoter is associated with development of Alzheimer's disease, depression, carcinoma of the pancreas in smokers, breast cancer and rheumatoid arthritis. It is interesting whether the -765 G/C polymorphism in COX-2-encoding gene promoter can be associated with COPD, a disease which is inflammatory in character. It is highly probable as the breast and pancreas cancers, whose associations with the analyzed polymorphism have been studied, are smoking-dependent tumors. Additionally, tobacco smoke has been demonstrated to induce COX-2 in the lungs. The study group consisted of 122 COPD patients (48 females, 74 males). The control group consisted of 149 healthy nonsmoking subjects (83 females, 66 males). Polymerase chain reaction/restriction fragment length polymorphism was used for genotyping. A statistically significant difference in genotype distribution was observed as a result of the comparison between healthy subjects and patients with COPD. The distribution of alleles in both groups conformed with Hardy-Weinberg equilibrium. In the group of COPD patients, GG allele was found in 79 subjects, GC in 36, and CC in 7 subjects (F = 0.094, P = 0.296927); in the control group, 73 subjects had GG allele, 68--GC and 8--CC (F = 0.12728, P = 0.120265). The allele frequency revealed differences between those groups, attaining the level of statistical significance (χ(2) = 29.043, df = 2, P = 0.0000. The carriers of -765 G allele are at 1.53-fold higher risk of developing COPD. The presence of GG genotype does not increase significantly the risk of the disease. It is also noteworthy that the carriers of CC or GC genotypes are at significantly lower risk of developing COPD than the group of subjects with GG genotype.

Abstract
In this study, we aimed to investigate a possible association of the COX-2 polymorphisms (-765G→C and -1195A→G) and with the risk of developing epithelial ovarian carcinoma (EOC). COX-2 gene polymorphisms was investigated in 111 healthy women and 57 patients with EOC. Individuals who had -765 CG, -1195 AA genotype, and -765 C allele had increased risk for ovarian carcinoma (P < 0.01) and individuals with -765 GG, -1195 AG genotypes and -1195 G allele seem to be protected from ovarian carcinoma (P < 0.01). Haplotype analysis confirmed the association of COX-2 gene variants with ovarian carcinoma and revealed that the frequencies of -765C: -1195A haplotype frequencies was significantly higher in patients as compared with those of controls (P = 0.048). We state that there appears to be a modulating role for the COX-2 -1195A→G and -765G→C polymorphisms in the development of EOC. To the best of our knowledge, this is the first study to show such an association.

Abstract
In this study, we aimed to investigate a possible association of the COX-2 polymorphisms with the risk of developing lung carcinoma. COX-2 (-765G→C; -1195A→G) gene polymorphisms were performed by polymerase chain reaction (PCR) and restriction fragment length polymorphism in 118 healthy individuals and 231 patients with lung carcinoma. The present study was the first that addressed the role of the COX-2-765G→C and -1195A→G polymorphisms in lung carcinoma in Turkish population. In the present study, we found that the frequencies of GG, CC, and CG genotypes of COX-2-765G→C and AA, GG, and AG genotypes of -1195A→G in our control group were 0.22, 0.22, 0.55 and 0.59, 0.0, 0.40, respectively. These frequencies in patient group were 0.34, 0.07, 0.58 and 0.74, 0.04, 0.24, respectively. There were statistically significant differences in COX-2-765G→C (P=0.0002) and -1195A→G genotypes (P=0.007) between the controls and patients. We found that individuals carrying -765 GG genotype and -765 G allele of COX-2 or 1195 AA genotype of COX-2 and -765G: -1195A haplotype had an increased risk for the development of lung carcinoma. In contrast, individuals with -765 CC, -1195 AG genotypes and -1195 G allele of COX-2 seem to be protective from lung carcinoma. We suggest that the COX-2-765G→C and -1195A→G genotypes may be a risk factor for lung carcinoma.

Abstract
BACKGROUND Cardiovascular disease is the leading cause of death among Americans. Inflammation is a hallmark of the development of atherosclerosis and is mediated by prostaglandins, catalyzed by cyclooxygenase (COX)-2. We sought to determine if variants in the COX-2 gene were associated with subclinical measures of cardiovascular disease in a primarily type 2 diabetic population. METHODS Eight polymorphisms in COX-2 were genotyped and vascular calcified plaque measured in the coronary, carotid, and aortic arterial beds in 977 Caucasian siblings (83% with T2DM) from 369 Diabetes Heart Study families. Tests for single nucleotide polymorphism (SNP) and haplotypic association were performed using SOLAR and quantitative pedigree disequilibrium test (QPDT), respectively (results adjusted for age, gender, diabetes affection status, smoking, and use of lipid altering medications). RESULTS All eight SNPs genotyped were found to be in strong pair-wise linkage disequilibrium (D'=1.0). Three SNPs (rs689466, rs2066826 and rs20417) are associated with either coronary or carotid calcified plaque. Subjects carrying the G allele of rs689466 (n=31) or the A allele of rs2066826 (n=16) had significantly lower coronary calcified plaque (P=0.02 and 0.04, respectively). Subjects homozygous for the C allele of rs20417 (n=22) or the A allele of rs2066826 (n=16) had increased carotid calcified plaque (P=0.011, P=0.014). In addition, multiple two-SNP and three-SNP haplotypes were associated with CorCP with P-values ranging from P=0.002 to P=0.035. CONCLUSIONS Polymorphisms in COX-2 were associated with significant changes in coronary and carotid calcified plaque. Diabetic individuals with these variants may be at higher risk for developing cardiovascular disease.

Abstract
BACKGROUND Cyclooxygenase (COX)-2 is an inducible enzyme responsible for catalysing the formation of prostaglandins (PGs) in settings of inflammation. Single nucleotide polymorphisms (SNPs) of the COX-2 gene may influence gene transcription and PG production in the asthmatic airway. OBJECTIVE To evaluate the frequencies of COX-2 SNPs in an Australian Caucasian population, and determine potential associations between common COX-2 promoter SNPs and asthma, asthma severity and aspirin-intolerant asthma (AIA). METHODS The frequencies of 25 COX-2 SNPs were determined in a random population (n=176). The SNPs with a minor allele frequency of >10% were then studied in asthmatic (n=663), non-asthmatic controls (n=513) and AIA subjects (n=58). Genotype, allele and haplotype associations were assessed. Functional assessment of SNPs was performed by transfection into HeLa cells measured using the luciferase dual-reporter assay system. RESULTS Eighteen COX-2 SNPs were not detected, five were rare and two promoter SNPs, -1195G>A (rs689465), and -1290A>G (rs689466), were further studied. The A allele of the -1195 SNP was present at a significantly higher frequency among all asthmatic subjects (P=0.012). Over 60% of the asthmatic individuals were -1195A homozygotes compared with 54.6% of the control subjects (odds ratio, 1.35; 95% CI, 1.06-1.72, P=0.03). After classifying for severity, the mild asthmatics represented 64.6% of -1195AA individuals, the highest of all the asthma groups compared with 54.6% of the control subjects (odds ratio, 1.5; 95% CI, 1.12-2.02, P=0.02). The -1290A/-1195G/-765G haplotype was associated with a reduced incidence of asthma (odds ratio, 0.76; 95% CI, 0.61-0.95, P=0.017). CONCLUSION The -1195G>A polymorphism appears to be associated with asthma, and in particular with mild asthma.

Abstract
AIM: To investigate -765G > C COX-2 polymorphism and H pylori infection in patients with gastric adenocarcinoma, peptic ulcer disease (PUD) and non-ulcer dyspepsia (NUD).
METHODS: We enrolled 348 adult patients (62 gastric adenocarcinoma, 45 PUD and 241 NUD) undergoing upper gastrointestinal endoscopy at two referral centers between September, 2002 and May, 2007. H pylori infection was diagnosed when any of the four tests (RUT, culture, histopathology and PCR) were positive. Genotyping for -765G > C polymorphism of COX-2 was performed by PCR-RFLP analysis.
RESULTS: Frequency of C carrier had significant association with gastric adenocarcinoma as compared to NUD [77.4% vs 29%, P < 0.001, odds ratio (OR) 8.20; 95% confidence interval (95% CI), 4.08-16.47] and PUD (77.4% vs 31.1%, P < 0.001; OR 8.04; 95% CI, 3.25-19.90). Risk of gastric adenocarcinoma was significantly higher in patients having C carrier with (OR 7.83; 95% CI 3.09-19.85) and without H pylori infection (OR 7.06; 95% CI, 2.61-19.09). Patients with C carrier and H pylori infection had significant risk for the development of PUD (P < 0.001; OR 5.65; 95% CI, 2.07-15.34).
CONCLUSION: -765G > C COX-2 polymorphism with or without H pylori could be a marker for genetic susceptibility to gastric adenocarcinoma. COX-2 polymorphism in presence of H pylori infection might be useful in predicting the risk of PUD.

Abstract
INTRODUCTION Genetic variants in the prostaglandin-endoperoxide synthase 2 (PTGS2) gene, which codes for COX-2, have been identified to modulate the response to COX-2-inhibiting drugs and to be possible risk factors for the incidence or prognosis of cardiovascular or neoplastic diseases, Alzheimer's disease, multiple sclerosis, asthma or osteoarthritis. Clinical evidence thus suggests a clinical importance of COX-2 genetics reaching from disease risk or prognostics up to a personalized therapy with COX-2 inhibitors. The aim of this study was to develop rapid and reliable screening assays for PTGS2 mutations with reported clinical consequences. METHODS SNPs (dbSNP-IDs rs689465, rs689466, rs3918304, rs20415, rs20417, rs5270, rs2745557, rs5277, rs2066826, rs4648276, rs5273, rs5275, rs4648298, rs689469) and a nucleotide-deletion variant (rs20431) were chosen according to reported functional associations. For this selection of variants spanning the whole PTGS2 gene range, Pyrosequencing assays were established in DNA from 350 healthy unrelated Caucasians. RESULTS In all 350 DNA samples, the 15 PTGS2 polymorphisms were identified correctly as verified by control samples obtained by conventional sequencing. In silico haplotype analysis based on ten SNPs of greater than 1% observed frequencies identified two haploblocks with a linkage disequilibrium of D' = 0.59. Approximately 50% of the reconstructed haplotypes consisted of non-mutated alleles. CONCLUSION The presently developed Pyrosequencing assays allow for quick and reliable detection of PTGS2 genotypes and may promote further research toward personalized approaches to pathophysiological conditions involving COX-2.

Abstract
BACKGROUND Neoplastic progression of BE towards EAC is associated with increased expression of COX-2. Increased COX-2 expression and enzyme activity is linked to the COX-2 CA haplotype, which consists of two gene polymorphisms in the COX-2 promoter. AIM To study the impact of COX-2 haplotypes on the risk of developing EAC in patients with different forms of gastroesophageal reflux disease including BE. METHODS DNA was obtained from a total of 635 Dutch white patients comprised of 140 patients with EAC, 255 with BE, and 240 with reflux esophagitis. COX-2 haplotypes were based on the gene polymorphisms at -765C/G and -1195A/G, as determined by PCR-RFLP. RESULTS The tested population contained 170 (14%) CA- (-765C and -1195A) haplotypes, 829 (65%) GA and 271 (21%) GG-haplotypes, and no GC-haplotypes. The haplotype distribution in patients with reflux esophagitis and BE was similar (CA 12%, GA 68%, GG 21%), but differed significantly from that in patients with EAC (CA 21%, GA 58%, GG 20%). Particularly, the CA-haplotype was more common (P < 0.001) in EAC patients. CA-carriership was associated with EAC (OR 2.8, 95% CI 1.3-6.2, P= 0.008), with homozygosity for the CA-allele being statistically most significantly associated (OR 6.1, 95% CI 1.6-24.2, P= 0.01). CONCLUSION The COX-2 CA-haplotype is more frequently observed in patients with EAC than in patients with BE and reflux esophagitis. These data suggest a direct link between COX-2 activity and neoplastic progression in patients with BE and reflux esophagitis.

Abstract
BACKGROUND Cyclooxygenase-2 (COX-2) plays essential roles in inflammation. Previous studies have suggested associations between prostaglandin-endoperoxide synthase 2 (PTGS2) polymorphisms and prostaglandins production in asthma. OBJECTIVE We have investigated the effects of Chinese tagging single nucleotide polymorphisms (SNPs) of PTGS2 on asthma traits in 299 Chinese asthmatic children and 175 controls. METHODS Plasma total and allergen-specific IgE were measured by enzyme immunoassay. PTGS2.8473T-->C in the 3'-untranslated region of exon 10 and three tag SNPs covering most of the variations in PTGS2 haplotypes in Chinese were genotyped by restriction fragment length polymorphism. RESULTS Among the four SNPs, only PTGS2.8473 showed significant association with asthma (P = 0.034) and atopy (P = 0.005 when compared with non-atopic controls; P = 0.023 with all controls). Carriers of the C allele had a 1.5-fold (95% confidence interval: 1.01-2.30) risk of developing asthma than those homozygous for the T allele. Multivariate regression revealed significant correlations between PTGS2.8473 and forced expiratory volume in 1 s (FEV(1); P = 0.002) and peak expiratory flow rate (PEFR; P = 0.001) with age and gender adjusted. Patients with the C allele of PTGS2.8473 had significantly lower FEV(1) (median: 90.0%vs 98.0%; P = 0.0047) and PEFR (70.0%vs 73.5%; P = 0.0065) than those homozygous for the T allele. No significant association between plasma total and allergen-specific IgE and these SNPs or with their haplotypes was found. CONCLUSIONS PTGS2.8473 polymorphism is associated with asthma, atopy and lung function but not plasma IgE in Chinese children. This may help to explore the pharmacogenetics of COX-2 inhibitors.

Abstract
Cyclooxygenase-2 (COX-2) is extensively expressed in multiple sclerosis lesions suggesting that regulatory variants of the COX-2 gene could be implicated in multiple sclerosis (MS). Screening of the proximal 5' regulatory region and genotyping of -765G>C and -62C>G showed that polymorphisms in this COX-2 region are unlikely to be involved in MS susceptibility.

Abstract
AIM: To investigate the relationship between the -765G > C COX-2 polymorphism and the development of different gastric lesions: atrophy or intestinal metaplasia and gastric adenocarcinoma.
METHODS: A cross-sectional study was performed involving 320 Portuguese individuals (210 without evidence of neoplastic disease, 73 patients with gastric adenocarcinomas and 37 with atrophy or intestinal metaplasia) using a PCR-RFLP method.
RESULTS: -765C allele was overrepresented in the patients with gastric adenocarcinoma (51%) when compared either with the control group (38%) or patients with atrophy or intestinal metaplasia (27%). Callele was found to be very common in our population (0.22), and a multivariate logistic regression analysis revealed nearly 3-fold increased risk for the progression to gastric adenocarcinoma in patients with atrophy or intestinal metaplasia carrying the -765C allele (OR = 2.67, 95% CI = 1.03-6.93; P = 0.04).
CONCLUSION: -765C carrier status should be considered as another susceptibility marker for gastric adenocarcinoma development in patients with atrophy or intestinal metaplasia.

Abstract
OBJECTIVE Recent data have shown an association between polymorphisms of prostaglandin-endoperoxide synthase-2 gene (PTGS2; alias COX-2), and prostaglandin-E receptor-2 gene (PTGER2) and risk of atherothrombotic disorders. METHODS We evaluated two PTGS2 (rs20417, rs689470), and three PTGER2 (rs708494/uS5, rs708495/uS7, and chr14: 50 764 013/uS10) gene polymorphisms among 600 Caucasian male participants of the Physicians' Health Study with incident myocardial infarction (MI) or ischemic stroke and 600 age- and smoking-matched controls who remained free of all reported cardiovascular disease. RESULTS Genotype distributions were in Hardy-Weinberg equilibrium in the control groups. Genotype and allele distribution were similar between cases and controls. The polymorphisms tested were in linkage disequilibrium. Results from the adjusted haplotype-based conditional logistic regression analysis showed a modest association of the PTGER2 2-1-1 haplotype with reduced risk of MI (odds ratio = 0.50, 95% CI; CI = 0.26-0.97, P = 0.04), and the 2-2-1 haplotype with reduced risk of ischemic stroke (odds ratio = 0.68, 95% CI = 0.47-0.99, P = 0.048). In contrast to prior data, we found no evidence for an association of the PTGS2 polymorphisms/haplotypes tested with risk of incident MI nor with ischemic stroke. However, we found suggestive evidence for an association of specific PTGER2 haplotypes with reduced risk of these outcomes. CONCLUSION Although these prospective data implicate the potential involvement of prostaglandin-E receptor-2 gene variation in atherothrombosis, external validation of our findings is needed.

Abstract
The objective of this study on colorectal cancer was to investigate the associations between SNPs in the genes involved in the arachidonic acid (AA)-pathway, their haplotypes and colorectal cancer. Moreover, interactions between SNPs and fish consumption were considered. In this study, a total of 508 cases and 772 controls were included, originating from 2 prospective cohorts, the Monitoring Project on Cardiovascular Disease Risk Factors (PPHV) and Diagnostisch Onderzoek Mammacarcinoom (DOM). Genotypes of 23 SNPs in 7 candidate genes were determined and the modifying effect of fish consumption was considered. A protective effect of the minor allele of SNP V102V in PTGS2 was observed (odds ratio (OR), 0.37; 95% confidence intervals (CI), 0.16-0.87). The haplotype representing this allele showed a weaker inverse association, indicating that 2 alleles are necessary to obtain this protective effect. Fish consumption data was available for 209 cases and 418 controls. Increased fish consumption was inversely associated with cancer, although not significant (OR, 0.83; 95% CI, 0.57-1.20). Despite the substantial reductions in cancer risk for some genotypes in combination with high fish intake, no significant interactions between any SNP studied and fish consumption were observed. We have previously described an association between colorectal adenomas and SNP V102V in PTGS2 and have now confirmed this association for colorectal adenocarcinomas. Fish consumption of once a week or more might protect against colorectal cancer, but no significant interactions with SNPs in the genes involved in the AA-pathway could be detected within the study.
