摘要 目的:丁酸钠(Bu)和阿司匹林(As)均对结肠癌具有预防作用,而小肠三叶肽(ITF)对胃肠黏膜有保护作用,有助于胃肠黏膜损伤和炎症的修复。本实验的目的在于明确Bu和As对结肠癌细胞SW480 ITF表达的影响。 方法:用原位杂交的方法检测不同浓度(1mm、2mm、5mm)Bu和As单独和联合作用前后SW480细胞中ITFmRNA的表达。设立不加Bu和As的对照组。统计方法采用方差分析,以P<0.05为差异显著标准。 结果:As及Bu均可使SW480细胞ITFmRNA表达减少,各组与对照组之间差异显著(As1,2,5mM组vs对照组P值分别为0.019,0.039,0.046;Bu1,2,5mM组vs对照组P值分别为0.038,0.022,0.007;As+Bu1,2,5mm组vs对照组P值分别为0.039,0.030,0.025).As+Bu组与单独应用As或Bu组间差异亦显著(As+Bu1 mm组vs As1 mM组P=0.045,vs Bu1mM组P=0.040;As+Bu2mM组vs As2mM组P=0.039,vs Bu2mM组P=0.046;As+Bu5mM组vs As5mM组P=0.015,vs Bu5mM组P=0.032).As+Bu3个浓度组间随剂量加大其ITFmRNA表达逐渐减少,差异具显著性(As+Bu1mM组vs As+Bu2mM组P=0.042,vs As+Bu5mM组P=0.017,As+Bu2mM组vs As+Bu5mM P=0.026)。但Bu或As 3个浓度组间差异均无显著性(P>0.05)。 结论:Bu及As均可抑制SW480细胞ITFmRNA的表达,且两者具协同效应。
