BACKGROUND/AIM: The current study aimed at evaluating the contribution of IL-13 promoter rs1881457 and rs1800925 genotypes to the risk of breast cancer in Taiwan.
A total of 1,232 breast cancer cases and 1,232 age-matched controls were genotyped by typical polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methodology.
As for IL-13 rs1881457, the rates of AA, AC and CC genotypes were 54.8, 37.9 and 7.3% among the cases, and 53.8, 38.7 and 7.5% among the healthy controls, respectively; there were no statistically significant differences between the two groups (p for trend=0.8889). Also, regarding IL-13 rs1800925, there were no statistically significant differences between the two groups either (p for trend=0.6803). Furthermore, the allelic frequencies for IL-13 rs1881457 and rs1800925 were not differentially distributed between the case and control groups (p=0.6515 and 0.8753, respectively).
The rs1881457 and rs1800925 IL-13 promoter polymorphisms may not serve as breast cancer susceptibility determinants for Taiwanese.
背景/目的:本研究旨在评估白细胞介素 13(IL-13)启动子 rs1881457 和 rs1800925 基因型对台湾地区乳腺癌风险的影响。
采用典型聚合酶链反应-限制性片段长度多态性(PCR-RFLP)方法对 1232 例乳腺癌病例和 1232 例年龄匹配的对照进行基因分型。
对于 IL-13 rs1881457,病例组 AA、AC 和 CC 基因型的频率分别为 54.8%、37.9%和 7.3%,对照组分别为 53.8%、38.7%和 7.5%;两组之间无统计学差异(趋势检验 p=0.8889)。同样,对于 IL-13 rs1800925,两组之间也无统计学差异(趋势检验 p=0.6803)。此外,IL-13 rs1881457 和 rs1800925 的等位基因频率在病例组和对照组之间也没有差异(p=0.6515 和 0.8753)。
IL-13 启动子 rs1881457 和 rs1800925 多态性可能不是台湾地区乳腺癌易感性的决定因素。
