Association between fibroblast growth factor 7 and the risk of chronic obstructive pulmonary disease.

ABSTRACT: AIM: Fibroblast growth factor 7 (FGF7) is involved in a number of physiological and pathological processes, including lung disease. However, relatively little is known about the effect of FGF7 gene polymorphisms on chronic obstructive pulmonary disease (COPD) susceptibility. This study aimed to investigate the association between FGF7 polymorphisms with COPD susceptibility in a Chinese Han population. METHODS: We conducted a case-control study of 279 COPD patients and 367 age- and gender-distribution-matched control subjects. The tagging SNPs rs10519225 and rs7170426 in FGF7 were genotyped by SNaPshot. The associations of each SNP genotype and haplotype constructed by these loci with COPD were analyzed. RESULTS: A multivariate analysis showed that rs10519225 was significantly associated with an increased risk of COPD (P=0.011, OR=1.535, FDR q=0.022), whereas no association was found for rs7170426. Linkage disequilibrium (LD) analysis showed that these loci were in weak LD, with an r(2) of 0.033 and a D' of 0.232 (95% CI: 0.150-0.520). The haplotype constructed by allele G at rs10519225 and allele A at rs7170426 was associated with a decreased susceptibility to COPD (P=0.012, OR=0.751, FDR q=0.048). CONCLUSION: These findings suggest that FGF7 may be one susceptibility factor for 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.
