Lack of association of Toll-like receptor 9 polymorphisms with susceptibility to systemic lupus erythematosus in an Asian population: a meta-analysis

Abstract

The association of Toll-like receptor 9 (TLR9) gene polymorphisms with systemic lupus erythematosus (SLE) risk remains controversial and ambiguous. To more precisely estimate the relationship between TLR9 gene polymorphisms and the susceptibility to SLE, a meta-analysis was performed. A total of seven independent studies were involved in this analysis. Meta-analysis was performed for three TLR9 gene polymorphisms (rs187084, rs352139, and rs352140). We have compared allele or genotype frequencies of the polymorphisms in SLE patients and controls. When available studies were pooled into the meta-analysis, there was no evidence showing a significant association between rs187084 and SLE risk in an Asian population (for C vs. T: OR = 0.81, P = 0.117; for CC vs. TT: OR = 0.71, P = 0.158; for CT vs. TT: OR = 0.86, P = 0.085; for CC + CT vs. TT: OR = 0.78, P = 0.093; for CC vs. CT + TT: OR = 0.81, P = 0.285). Similar results were found between rs352139 and SLE. No significant association was detected in any genetic model in the Asian population either (for G vs. A: OR = 1.11, P = 0.095; for GG vs. AA: OR = 1.32, P = 0.238; for GA vs. AA: OR = 1.17, P = 0.084; for GG + GA vs. AA: OR = 1.17, P = 0.073; for GG vs. GA + AA: OR = 1.17, P = 0.404). We found no association between TLR9 gene rs352140 polymorphism and SLE in the Asian population (for A vs. G: OR = 1.02, P = 0.728). In conclusion, there is still not enough evidence to indicate an association between TLR9 gene rs187084, rs352139, and rs352140 polymorphisms and the development of SLE in the Asian population.     

Association between FGFR4 gene polymorphism and high-risk HPV infection cervical cancer

Objective: To discuss the association between FGFR4 gene polymorphism rs351855(Glu388Aly) and the susceptibility and chemotherapeutic effect of cervical cancer infected by high-risk type HPV. Methods: A total of 162 patients with high-risk HPV cervical cancer and 162 healthy women were collected and the genotypes of the FGFR4 rs351855 locus were detected. The genotype distributions in the two groups were compared. The cervical cancer patients were divided into four groups which namely good therapeutic effect group and bad therapeutic effect, recurrence or metastasis and no recurrence or metastasis group respectively, and the risks of different genotype on the curative effect and prognosis were analyzed by Logistic regression. The survival time of patients with different genotypes was compared. Results: There was no statistic difference in FGFR4 rs351855 genotype distribution between the patients group and control group(P0.05), among which the risk of chemotherapy failure on GA+AA patients was 3.257 times as much as that of the GG patients, and the risk of recurrence or metastasis of GA+AA patients was 2.783 times as much as that of the GG patients. For AA patients, the risk of chemotherapy failure and the risk of relapse and metastasis are 3.833 and 3.406 times, respectively, as much as that that of the GG patients. The overall survival of GA and AA patients was shorter than that of the GG patients, and significant difference was found(x~2=7.098, P=0.029). The difference in overall survival between GA+AA patients and GG patients was almost statistically significant(x~2=3.634, P=0.057). Conclusions: The FGFR4 rs351855 polymorphism is not associated with the susceptibility of high-risk HPV cervical cancer, but patients with gene A was at higher risk of unfavourable chemotherapy prognosis compared with patients with GG.     

Cytotoxic T-lymphocyte associated antigen-4 gene polymorphisms and primary biliary cirrhosis: a systematic review

Background and Aim: The cytotoxic T‐lymphocyte antigen 4 (CTLA4) is an inhibitory receptor expressed on activated and regulatory T lymphocytes. Polymorphisms could have remarkable effects on susceptibility to autoimmunity. However, the associations between CTLA‐4 polymorphisms and primary biliary cirrhosis (PBC) remain ambiguous. The aim of this meta‐analysis is to determine more precise estimations of the relationship. Methods: From literature retrieval from PubMed, Web of Science, Science Direct, and the Chinese National Knowledge Infrastructure (CNKI) Database, the publications on the associations between rs231775, rs3087243, rs5742909, rs231725 and rs11571317 polymorphisms of CTLA4 and PBC through June 2011 were collected. Odds ratios (OR) with 95% confidence intervals (95% CI) were calculated in fixed or random model, I² was calculated to examine heterogeneity, and funnel plots were plotted to examine small study effects with Revman 5.1 and Stata 11. Results: Overall, a significantly increased risk was found for G versus A allele for rs231775 (OR = 1.28, 95% CI = 1.17–1.41). For rs3087243, a significant association was found for AA versus GG genotype (OR = 0.66; 95% CI = 0.55–0.80). When subgroup analysis by ethnicity was performed, the same association was only found in Caucasians. For rs231725, the OR values (95% CI) for GG versus AA, GA versus AA and G versus A allele were 0.52 (0.40–0.68), 0.74 (0.60–0.92) and 0.73 (0.61–0.88). No significant associations were found for other polymorphisms. Conclusion: The G allele of rs231775 is a risk factor for PBC, while AA genotype of rs3087243 and GG, GA and G allele of rs231725 show negative associations with PBC.     

RUNX3基因rs2236852多态性与胃癌的关系

背景:Runt相关转录因子3(RUNX3)基因多态性与亚洲人群胃癌的发生相关。目的:初步探讨RUNX3基因rs2236852多态性与中国汉族人群胃癌发病风险之间的关系。方法:选取2011年3月～2013年4月青岛大学医学院附属青岛市市立医院确诊的310例胃癌患者,以327名健康者作为对照。采用DNA直接测序法检测RUNX3rs2236852位点基因型,并分析其与胃癌发病风险之间的关系。结果:胃癌组RUNX3 rs2236852基因型分布频率与对照组相比差异有统计学意义(P<0.05)。与AA基因型相比,GG基因型能显著增加胃癌的发病风险(OR=2.46,95%CI:1.60～3.78);AG基因型可增加胃癌发病风险,但差异无统计学意义(OR=1.58,95%CI:0.99～+2.54)。结论:RUNX3 rs2236852位点GG基因型可能与中国汉族人群的胃癌发病有关。     

SLCO1B1c.388A＞G多态性对于中国缺血性卒中患者阿托伐他汀降脂和抗动脉粥样硬化作用的影响

目的 探讨溶质载体有机阴离子转运体家族1B1(solute carrier organic anion transporterfamily member l B1,SLCO1 B1)基因c.388A＞G多态性对中国缺血性卒中患者阿托伐他汀降脂和抗动脉粥样硬化作用的影响.方法 前瞻性纳入基线低密度脂蛋白胆固醇(low-density lipoprotein cholesterol,LDL-C)＞ 1.8 mmol/L的缺血性卒中患者,口服阿托伐他汀(20 mg/d)治疗12个月,分别在治疗前后检测血脂和双侧颈动脉内膜-中膜厚度(carotid intima-media thickness,CIMT).比较SLCO1 B1基因c.388A＞G基因型组之间CIMT的差异.结果 共纳入71例缺血性卒中患者,其中AA基因型5例,AG基因型31例,GG基因型35例;A等位基因频率为28.9％,G等位基因频率为71.1％.所有患者治疗后总胆固醇、三酰甘油和LDL-C均较治疗前显著降低,而高密度脂蛋白胆固醇显著升高(P均＜0.001),但CIMT无显著改变(P=0.475).GG基因型组LDL-C＜ 1.8 mmol/L或LDL-C下降≥50％的患者比例显著高于AG+AA基因型组(74.29％对44.44％;x2=6.540,P=0.011).结论 SLCO1B1基因c.388A＞G多态性会影响阿托伐他汀的降脂效果,GG基因型组的降脂效果优于AG+AA基因型组;SLCO1 B1基因c.388A＞G多态性对阿托伐他汀抗动脉粥样硬化疗效无影响,但可能与随访时间过短有关.
