Abstract´╝Ü 目的:探讨转化生长因子β1基因(TGF-β1)C-509T多态与结直肠癌(colorectal cancer,CRC)遗传易感性的关系.方法:采用TaqMan方法检测345例CRC与670名对照的TGF-β1 C-509T基因型分布及差异.结果:CRC组与对照组T等位基因频率分别为43.5%、48.8%,T的CRC发病风险是C的0.82倍(95%CI 0.68-0.99,P=0.037).与CC纯合子相比,CT杂合子引起CRC风险为0.79倍(95%CI 0.58-1.08,P=0.137),而TT纯合子引起CRC风险显著降低至0.66倍(95%CI0.45-0.96,P=0.032).将CT、TT基因型合并计算,则其CRC发病风险与CC基因型相比降低至0.75倍(95%CI 0.56-1.00,P=0.052).结论:TGF-β1基因C-509T多态是中国人群重要的CRC遗传保护因子,可作为CRC发病风险评估的筛选指标.
