摘要 目的研究姜黄素对体外培养人结肠癌Caco2细胞增殖及对细胞株中MACC-1、前列腺素(PG)E2表达的影响。方法采用不同浓度姜黄素作用于Caco2细胞,MTT法检测细胞增殖情况;利用酶联免疫吸附试验(ELISA)检测药物作用后肿瘤细胞PGE2蛋白质水平表达变化,Western印迹检测药物处理后MACC-1与c-Met表达。结果姜黄素对Caco2细胞的增殖具有抑制作用,且呈剂量-时间依赖性(P<0.05),测得半数致死量(IC50)为49.5μmol/L;在蛋白水平,姜黄素处理后,MACC-1与c-Met蛋白表达水平降低。结论姜黄素能够抑制Caco2细胞的增殖,并下调结肠癌细胞Caco2中PGE2、MACC-1的表达。
