Abstract

Axis inhibition protein 2 (Axin2) is a negative regulator of the canonical Wnt/β-catenin signaling pathway, and functions as a tumor suppressor in a number of human cancers. Previous pilot studies have suggested an association between Axin2 exon1 148 (rs2240308) SNP polymorphism and risk for lung cancer. In the present study, we aimed to investigate the Axin2 exon1 148 polymorphism and its association with lung cancer susceptibility in Han Chinese population. The Axin2 exon1 148 SNP was genotyped in 555 controls and 520 lung cancer patients using TaqMan SNP Genotyping Assays. Unconditional logistic regression analysis was used to calculate adjusted odds ratios (ORs) and 95 % confidence intervals (CIs). We observed that the genotype frequencies of TC, TT, and CC were significantly different between controls and cases (χ 2 = 6.849, P = 0.03256, df = 2). Subjects carrying T allele (TC + TT genotypes) had decreased susceptibility to lung cancer as compared to those carrying CC genotype (OR = 0.733, 95 % CI = 0.5726–0.9393, P = 0.01382). No significant association was found between rs2240308 polymorphism and histological subtypes of lung cancers. Findings from this study suggest that Axin2 exon1 T148C polymorphism (rs2240308) contributes to increased susceptibility to lung cancer in Chinese population. This further implicates Axin2 as a lung cancer-related gene.
