Caspase 7 influences susceptibility to rheumatoid arthritis

OBJECTIVE: The aim of this study was to investigate the possible role of the caspase 7 (CASP7) in susceptibility to rheumatoid arthritis (RA). METHODS: Genotyping of three single nucleotide polymorphisms (SNPs) of the CASP7 gene: rs11593766 (G/ T), rs2227310 (C/G) and rs2227309 (G/A) was performed in a total of 906 RA patients and 528 matched healthy controls using TaqMan assays. All the subjects were of Spanish Caucasian origin. A relative quantification of mRNA encoding the non-functional variant of procaspase 7 (isoform beta) vs functional isoforms was performed in total RNA from 32 healthy individuals using real-time PCR. RESULTS: Only the rs2227309 SNP was found to be associated with susceptibility to RA. Frequency of the G allele was significantly higher among RA patients [overall frequency of the G allele 74.0% in cases vs 68.4% in controls, P = 0.001, Odds ratio (OR) = 1.32, 95% Confidence intervals (95% CI) 1.11-1.56] and a higher frequency of GG homozygous individuals was found in the RA patient group (overall frequency of GG genotype 56.0% in cases and 46.4% in controls, P = 0.0005, OR = 1.47, 95%CI 1.18-1.83). A statistically significant deviation was observed to compare the relative expression of the procaspase 7 isoform beta in samples from individuals stratified according their rs2227309 genotypes (AA + AG: 1.36 +/- 0.55, n = 19, vs GG: 2.35 +/- 0.74, n = 13; P = 0.0002). CONCLUSION: Our results support involvement of the CASP7 gene in the susceptibility to RA. The higher production of the no functional variant of CASP7 by individuals with a particular genotype could be the basis of this association.     

Interleukin-21 gene polymorphisms and chronic hepatitis B infection in a Chinese population

AIM: To investigate the relationship between inter-leukin-21(IL21) gene polymorphisms and chronic hepatitis B virus(HBV) infection in a Chinese population. METHODS: In this case-control study, 366 Chinese HBV-infected patients were recruited and divided into hepatocellular carcinoma(HCC; n = 94) and non-HCC(n = 272) groups at The First Affiliated Hospital of Sun Yat-Sen University, from April 2009 to December 2012. In the non-HCC group, the patients were classified into three clinical subsets, 76 patients had chronic hepatitis B, 101 were HBV carriers and 95 patients had HBV-related cirrhosis. Two hundred eight unrelated healthy controls were also included. Genomic DNA was extracted from peripheral blood. Single nucleotide polymorphisms(SNPs) rs13143866, rs2221903, and rs907715 were subsequently genotyped using the SNaP shot SNP technique.RESULTS: There were no significant differences in allele and genotype frequencies of SNPs rs13143866, rs2221903, and rs907715 between chronic HBVinfected patients and control subjects. Furthermore, no significant differences were found in the frequencies of all alleles and genotypes between the HCC group and the non-HCC group. However, in the subgroup analysis, IL21 rs13143866 genotype AA frequency in the HBV carrier group was higher than in controls(OR = 6.280, 95%CI: 1.238-31.854; P = 0.019), and the effect of the recessive model(AA vs GG + GA, OR = 6.505, 95%CI: 1.289-32.828) was observed in the HBV carrier group. IL21 rs2221903 genotype TC frequency in the HBV carrier group was higher than in controls(OR = 1.809, 95%CI: 1.043-3.139; P = 0.035). In the haplotype analysis, the ATA haplotype(rs13143866, rs2221903, and rs907715) of IL21 was more frequent in the HCC group than in the non-HCC group(0.165 vs 0.104, P = 0.044; OR = 1.700, 95%CI: 1.010-2.863).CONCLUSION: Genotypes rs13143866 AA and rs2221903 TC are risk factors for carrying HBV; ATA haplotype increases the risk of HBV-related HCC onsetin a Chinese population.

Interleukin-17A gene variants and risk of coronary artery disease:a large angiography-based study

Background Recent studies have also revealed that interleukin(IL)-17A plays a key role in atherosclerosis and its complication,but the relationship of its common variants with coronary artery disease(CAD) has not been extensively studied.Methods We systematically screened sequence variations in the IL17A gene and designed an angiog-raphy -based case-controlled study consisting of 1031 CAD patients and 935 control subjects to investigate the association between the selected polymorphisms of IL-17A gene and CAD risk in Chinese Han population.Results Frequencies of IL17A rs8193037 GG homozygote and G allele were significantly higher in the patient group than those in the control group(P<0.001;OR=0.68;95%CI=0.54-0.85).Stratification analysis showed that the IL17A rs8193037 G allele significantly increased the risk of CAD only among male subjects (P=0.001;OR=0.63;95%CI=0.47-0.83).After adjustment for conventional risk factors,binary logistic regression analysis showed that the G allele carriers(GG +AG) had significantly increased CAD risk compared with the AA homozygotes (adjusted P<0.001;OR 0.43;95%CI,0.33- 0.58).ELISA showed augmented IL17A production in plasma of the AMI patients.Conclusions Based on our data,we speculated that the SNP rs8193037 of IL17A gene is significantly associated with CAD risk in Chinese Han population and the rs8193037 G allele which is associated with increased expression of IL17A in AMI patients may be an independent predictive factor for CAD.     

Association between COX-2-1195G>A polymorphism and gastrointestinal cancer risk: A meta-analysis

AIM To perform a meta-analysis to investigate the association between cyclooxygenase-2(COX-2)-1195GA gene polymorphism and gastrointestinal cancers. METHODS Publications related to the COX-2-1195GA gene polymorphism and gastrointestinal cancers published before July 2016 were retrieved from Pub Med, EMBASE, Web of Science, China Biological Medicine Database, China National Knowledge Infrastructure, and CQVIP Database. Meta-analysis was performed using Stata11.0 software. The strength of the association was evaluated by calculating the combined odds ratios(ORs) and the corresponding 95%CIs. The retrieved publications were excluded or included one by one for sensitivity analysis. In addition, the funnel plot, Begg's rank correlation test, and Egger's linear regression method were applied to analyse whether the included publications had publication bias. RESULTS A total of 24 publications related to the COX-2-1195GA gene polymorphism were included, including 28 studies involving 11043 cases and 18008 controls. The meta-analysis results showed that the COX-2-1195GA gene polymorphism significantly correlated with an increased risk of gastrointestinal cancers, particularly gastric cancer(A vs G: OR = 1.35; AA/AG vs GG: OR = 1.54; AA vs GG/AG: OR = 1.43; AA vs GG: OR = 1.80; AG vs GG: OR = 1.35). Compared to the Caucasian population in America and Europe, the COX-2-1195GA gene polymorphism in the Asian population(A vs G: OR = 1.30; AA/AG vs GG: OR= 1.50; AA vs GG/AG: OR = 1.35; AA vs GG: OR = 1.71; AG vs GG: OR = 1.37) significantly increased gastrointestinal cancer risk. The sensitivity analysis(P 0.05) and the false positive report probability(P 0.2) confirmed the reliability of the results. CONCLUSION The results showed that the COX-2-1195GA gene polymorphism might be a potential risk factor for gastrointestinal cancers. Further validation by a large homogeneous study is warranted.

An adequate response of the innate immune system after allo-SCT is crucial for the clinical outcome of patients submitted to this procedure. EP300 is one of the key genes of the innate immune system (IIS). We evaluated the influence of gene variant A>G rs20551 in EP300 in donor and/or recipient on clinical results after HLA-identical sibling allo-SCT. Patients with AA gene variant had a lower relapse incidence (31 vs 48%, P=0.025; odds ratio (OR)=1.6, P=0.05), attained better disease-free survival (AA: 53% vs AG+GG: 24%, P=0.001; OR=1.8, P=0.01), and better OS (AA: 53% vs AG+GG: 34%, P=0.001; OR=1.9, P=0.007). This beneficial association was more evident when AA gene variant was present in both donor and patient. In healthy individuals, AA gene variant was associated with lower IL2 production after a mitogenic stimuli, higher CD4+ cell response after CMV infection, and higher expression of innate immune genes (IRF-3 and MIF), cell cycle genes (AURKB, CCNA2 and CCNB1), lymphocyte survival genes (NFAT5 and SLC38A2), and with a lower expression of P53 compared with recessive GG gene variant. These findings suggest a beneficial effect of the AA gene variant in rs20551 on clinical outcome after allo-SCT.     

IL-17 polymorphisms and asthma risk: a meta-analysis of 11 single nucleotide polymorphisms

Objective: There has been significant interest in the association between asthma and the polymorphisms of IL-17A and IL-17F for a period of time. This work aims to present a clearer relationship between asthma and the polymorphisms of IL-17A and IL-17F. Method: Searches were performed in Medline, EMBASE, and the Chinese National Knowledge Infrastructure (CNKI) databases. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the relationship between polymorphisms of IL-17A and IL-17F and asthma. Results: Nine studies comprising 3650 asthmatics and 3370 controls were included in this meta-analysis for all single nucleotide polymorphisms (SNPs) (2–6 per SNP). Our study examined the polymorphisms of IL-17F rs1889570 (C/T) (CC versus TT: OR?=?0.55, 95%CI?=?0.41–0.75; CT versus TT: OR?=?0.54, 95%CI?=?0.40–0.72; CC/CT versus TT: OR?=?0.55, 95%CI?=?0.42–0.72; CC versus CT/TT, OR?=?1.83, 95%CI?=?1.39–2.41), IL-17A rs4711998(A/G) (AA/AG versus GG: OR?=?0.67, 95%CI?=?0.46–0.98), and IL-17A rs3819024(A/G) (AA versus GG: OR?=?1.77, 95%CI?=?1.39–2.25) and found they were significantly related to the risk of asthma. Conclusion: Our systematic review showed that IL-17F rs1889570(C/T), IL-17A rs4711998(A/G) and IL-17A rs3819024(A/G) may be potential risk factors for asthma susceptibility.

Genetic polymorphisms in IL10RA and TNF modify the association between blood transfusion and risk of non-Hodgkin lymphoma

We conducted a population-based case-control study in Connecticut women to test the hypothesis that genetic variations in Th1 and Th2 cytokine genes may modify the association between blood transfusion and risk of non-Hodgkin lymphoma (NHL). Compared with women without blood transfusion, women with a history of transfusion had an increased risk of NHL if they carried IL10RA (rs9610) GG genotype [odds ratio (OR) = 1.9, 95% confidence interval (CI): 1.1-3.2] or TNF (rs1800629) AG/AA genotypes (OR = 1.6, 95% CI: 0.9-2.7). We also found women with a history of transfusion had a decreased risk of NHL if they carried IL10RA (rs9610) AG/AA genotypes (OR = 0.6, 95% CI: 0.4-0.9) or TNF (rs1800629) GG genotype (OR = 0.7, 95% CI: 0.5-1.0). A similar pattern was also observed for B-cell lymphoma but not for T-cell lymphoma. Statistically significant interactions with blood transfusion were observed for IL10RA (rs9610) (P(forinteraction) = 0.003) and TNF (rs1800629) (P(forinteraction) = 0.012) for NHL overall and IL10RA (rs9610) (P(forinteraction) = 0.001) and TNF (rs1800629) (P(forinteraction) = 0.019) for B-cell lymphoma. The results suggest that genetic polymorphisms in TNF and IL10RA genes may modify the association between blood transfusion and NHL risk.
