摘要 目的:观察甲基化转移酶抑制剂zebularine对人胃癌SGC-7901细胞株抑癌基因p16表达的影响。方法:采用MTT法和划痕实验检测zebularine对人胃癌SGC-7901细胞株的抑制率及其细胞迁移率的影响,采用real-time PCR检测作用前后抑癌基因p16表达的变化。结果:⑴终浓度100μmol/L的zebularine作用24 h能显著抑制SGC-7901细胞株的增殖率和迁移率。MTT法对照组吸光度为0.50±0.01,实验组为0.45±0.02,两组间差异有统计学意义(P<0.05);对照组划痕愈合率为(47.45±10.05)%低于实验组的(88.23±5.45)%(P<0.05)。⑵zebularine作用24 h能显著增加抑癌基因p16mRNA的表达,实验组为5.21±0.67显著高于对照组的1.04±0.09(P<0.05)。结论:甲基化转移酶抑制剂zebularine可以有效抑制SGC-7901细胞株的增殖和迁移并提高抑癌基因p16mRNA的表达。
