目的 探讨聚腺苷酸二磷酸核糖转移酶-1(PARP-1)Val762Ala(T2444C)基因多态性与中国西部甘肃省人群胰腺癌易感性的关系,筛查预测胰腺癌的分子标记.方法 选取85例良性胰腺疾病患者(对照组)与66例胰腺癌患者(胰腺癌组),用基质辅助激光解吸电离飞行时间(MALDI-TOF)质谱技术对SNP基因位点进行基因分型,采用x2-test比较分类变量和各SNP基因分型在病例组和对照组中的分布差异,评价各基因型与胰腺癌发病风险的关系.结果 PARP-1 2444C等位基因型(TC+CC)胰腺癌组明显高于良性对照组,TC+ CC基因型携带者患胆管癌的风险是TT基因型者的3.4倍(OR 3.377,95％CI:1.715～6.646,P＜0.001).结论 本组数据显示PARP-1 Val762Ala(T2444C)单核苷酸多态性与胆管癌易感性相关,C等位基因型携带者惠胰腺癌风险相对较高,PARP-1 Val762Ala(T2444C)单核苷酸多态性可作为预测胰腺癌的生物标志物.
