摘要
目的:研究白细胞介素-1(IL-1)B和IL-1受体拮抗剂(IL-1 ra)基因多态性与胃癌易患性的关系。方法:应用基因芯片、聚合酶链式反应(PCR)和PCR-限制性片段长度多态性(PCR-RFLP)技术对65例胃癌患者和71例健康对照IL-1B-31和-511及IL-1 ra基因多态性进行了分析。结果:与对照组相比,胃癌患者IL-1B-31T/T携带者、IL-1B-511C/C携带者显著增加(2χ=6.014,P<0.01;2χ=9.533P<0.001)。其他等位基因或基因型未见差异。结论:胃癌的易患性与IL-1B-31TT和IL-1B-511CC基因型可能有关。
Objective: To study relationship between interleukin-lB gene and interleukin-1 receptor antagonist gene polymorphisms and susceptibility to gastric cancer. Methods: A total of 71healthy controls and 65 patients with gastric cancer were genotyped by gene chip, polymerase chain reaction (PCR) and PCR- restriction fragment length polymorphism (PCR-RFLP) for IL-1 B-31 and -511 single nucleotide polymorphism (SNP) of IL-1B promoter, and IL-1 ra gene 86bp variable number of tandem repeat(VNTR) poly- morphism of IL-1ra gene intron 2(for five different alleles) Results: Comparison of the IL-1B-31TT genotype and -511 CC genotype frequencies showed a significant difference between patients with gastric cancer and healthy controls(χ^2= 6. 014,P 〈 0.01 ; χ^2 = 9. 533 P 〈 0. 001, respectively). No association with patients was found for other investigated polymorphisms in the IL-1 B-31 ,-511 and IL-1 ra genes. Conclusion: The results indicated that susceptibility to patients with gastric cancer was increased in individuals carrying both the IL-1B-31TT and IL-1B-511CC genotype.
