• FoxP3 regulates regulatory T-cell development and function and could modulate susceptibility to non-small cell lung cancer.
• FoxP3 rs3761548 was analyzed in a hospital-based case-control study of 192 NSCLC patients and 259 healthy subjects using PCR-RFLP.
• FoxP3 AC, AA, and AA+AC genotype of rs3761548 were associated with NSCLC risk in the Chinese Han population.
CD4+CD25+ regulatory T cell-mediated immunosuppression is one of the crucial mechanisms that tumor cells use to evade the immune system. The forkhead box P3 (FoxP3) gene regulates regulatory T-cell development and function and may modulate the susceptibility to non-small cell lung cancer (NSCLC). Because a single nucleotide polymorphism (SNP) within the FoxP3 gene (rs3761548 in the promoter region) is associated with susceptibility to Graves' disease, this study detected rs3761548 in a hospital-based case–control study. A total of 192 NSCLC patients and 259 healthy subjects were recruited for the polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP) analysis of FoxP3 SNP. The data showed that the A allele of rs3761548 significantly increased NSCLC risk (P = 0.000, OR = 2.32, 95%CI = 1.736–3.102). The AC genotype, AA genotype, and the combined A variant genotype (AA + AC) were also associated with a higher risk of NSCLC (OR [95%CI] = 2.147[1.419–3.247], 4.413[2.359–8.255], and 2.563[1.746–3.761], respectively). Moreover, a significantly higher frequency of AA + AC genotype was observed in patients with stage II NSCLC (OR, 2.053; 95%CI, 1.033–4.078). In conclusion, the data from the current study demonstrated for the first time the association of the FoxP3 SNP with a risk of developing NSCLC in the Chinese Han population.
