摘要
目的：研究IL-1基因簇中IL-1B基因启动子区+3954位点单核营酸多态( SNP)和IL-1RN基因可变数目串联重复多态性(VNTR)与乳腺癌易感性的关系及其基因频率与乳腺癌分子分型之间的关系，方法：采用聚合酶链反应(PCR)和限制性片段长度多态性分析(RFLP)的方法，分析223名乳腺癌病人及284例当地健康对照者的IL-1B+3954基因位点和IL-1RN基因多态性，计算基因型频率(genotype frequencies)和等位基因频率(alele-frequencies)。各基因多态性位点的等位基因频率用经过x2检验确定的Hardy-Weinberg平衡检验。各等位基因的频率以及基因型的分布频率用优势比(OR)及其95%可信区间(95% CI)表示的相对风险度分析。结果：IL-IB+3954和IL-1 RN的基因型频率和等位基因频率在乳腺癌患者组和对照组之间无显著性差异((P>0.05)。各单倍型在乳腺癌患者组和对照组之间也无显著性差异((P>0.05)。在不同肿瘤增值指数组，IL-1B+3954位点SNP基因和等位基因在不同增值指数患者中的频率分布有显著性差异((P<0.05)。结论：IL -1B+3954和IL-1RN基因多态性与乳腺癌的发病率无相关性，但可能与乳腺癌细胞的增殖指数相关。
Abstract
To investigate the relationship between the geneticgene singlenucleotide polymorphisms(SNPs) at positions+3954, variable number tandem repeat (VNTR) polymorphism in IL-LB gene intron 2 and risk of breastcancer,and find the association between the factor and the subtype of breastcancer.Methods:Techniques of polymerase chain reaction(PCR) and restrictionfragment length polymorphism(RFLP),were used to analyze the polymorphisms of IL-1B+3954 and IL-1RN in 223 cases of CP patients and 284 periodontalyhealthy controls ,and calculate their genotype frequencies and alele frequencies. Genotypes distributions were examined for significant departure from the Hardy--Weinberg equilibrium by a goodness of fit x2test.Odds ratioat 95% confidence interval (CI) were calculated to compare risk of the breast cancer between the examined genotypes.Chi squared analysis was used to examine differences in the proportion of the examined genotypes between different subgroups.Results: The genotype and alele distributions of IL-1B+3954 andIL-1RN showed the differences were not significant (P>0.05). There were also nosignificant differences between the breastcancer and control groups for the haplotypes (P>0.05). There were significant differences between the high value-added index and low value-add index for IL-1B+3954 (P<0.05).Conclusion:IL-1B+3954 andIL-1RN genotype weren’t related to patients with breast cancer; IL-1B+3954 were signif icantly relat ed to patient s with breast cancer with KI-67>14%.
