Association of IREB2 Gene rs2568494 Polymorphism with Risk of Chronic Obstructive Pulmonary Disease: A Meta-Analysis.

ABSTRACT: It is reported that the iron-responsive element-binding protein 2 (IREB2) gene rs2568494 polymorphism might be associated with COPD risk. The purpose of this meta-analysis was to collect all eligible studies to review the association between IREB2 gene rs2568494 polymorphism and susceptibility to COPD.We carried out a comprehensive document search of electronic databases of PubMed, MEDLIN, Web of Science, and included 4 eligible studies that examined the association between IREB2 rs2568494 polymorphism and COPD susceptibility. We performed a meta-analysis of these studies based on IREB2 rs2568494 genotypes.After meta-analysis with fixed or random effects, no significant associations were found under the heterozygote model (GG/GA; OR=0.908, 95%CI: 0.790-1.043; P=0.172), homozygote model (GG/AA; OR=0.880, 95%CI: 0.497-1.557; P=0.661), dominant model (GG/AA+GA; OR=0.941, 95%CI: 0.748-1.182; P=0.599), or allelic model (G/A; OR=0.953, 95%CI: 0.770-1.179; P=0.655). However, we found a significant correlation under the recessive model (AA/GA+GG; OR=1.384, 95%CI: 1.092-1.755; P=0.007).The current results revealed that there was significant association between IREB2 gene rs2568494 polymorphism with susceptibility to COPD; the presence of allelic A might a genetic factor conferring susceptibility to COPD.

Project description:BackgroundThe association between the oxidative stress gene polymorphism and chronic obstructive pulmonary disease (COPD) risk has been extensively studied but the results have been controversial. This study aimed to investigate the overall association between the oxidative stress gene including glutathione S-transferase (GST), epoxide hydrolase exon (EPHX), superoxide dismutase (SOD), catalase (CAT), cytochrome P450 system (CYP) and heme oxygenase (HO-1) polymorphism and the risk of COPD.MethodsWe searched the PubMed and EMBASE database to identify studies that investigated the association between the oxidative stress gene polymorphism and risk of COPD. The relevant data were extracted and statistical analyses were performed using the Revman 5.4 and STATA 12 software. Dominant genetic model, recessive model, co-dominant model, heterozygote model, and allele model were analyzed. Venice criteria and publication bias were conducted to access the credibility and reliability.ResultsIn total, 63 publications including 14,733 patients and 50,570 controls were included in the meta-analysis.15 genetic variants of 6 genes were analyzed, and 7 SNPs in GSTP1, CAT, CYP, SOD were first analyses until now. In our study, EPHX T113C C allele, GSTM1 null, GSTT1 null, GSTP1 A313G G and C341T T allele, CYP1A1 MspI C allele, SOD3 A213G G allele and L type in Ho-1 showed increased COPD risk, especially in Asians. T allele in CAT C262T and C allele in SOD2 Val 9 Ala were associated with decreased COPD risk. To avoid high heterogeneity and publications bias, subgroups analysis was performed in accord with HWE and ethnicity. Publication bias was assessed by Begg's funnel plots and Egger's test, and no publication bias were found for recessive models. 4 variants were identified with strong levels of epidemiological evidence of associations with the COPD risk.ConclusionsOur results confirm that oxidative stress gene polymorphism was associated with COPD risk. These finding can improve human understanding of this disease gene molecular level and enable early intervention and prevention of COPD. Well-designed studies with large sample sizes are essential to clarify the association of these significant variants with the susceptibility to COPD.
