摘要 目的研究甲基化寡核苷酸灭活Dickkopf相关蛋白3(Dickkopf-related protein 3,DKK3)基因对Hep G2肝癌细胞增殖的影响。方法采用甲基化特异性PCR法检测肝癌细胞DKK3基因启动子甲基化状态。将寡核苷酸(分别为MON组、UMON组、CON1组和CON2组)转染Hep G2肝癌细胞,比较转染后DKK3基因启动子甲基化状态、细胞增殖和凋亡的差异。结果 Hep G2肝癌细胞DKK3基因启动子未检测到甲基化,Hep3B、SMMC-7721和Hu H-7肝癌细胞DKK3基因启动子处于甲基化状态。MON可成功诱导其互补序列CG位点产生甲基化,而UMON、CON1和CON2寡核苷酸无法诱导甲基化。UMON组、CON1组和CON2组Hep G2肝癌细胞在D0-D6吸光度、G_0/G_1期、S期、G_2/M期、增殖指数(proliferation index,PI)和凋亡率方面差异均无统计学意义(均P>0.05);MON组Hep G2肝癌细胞G_0/G_1期比例和凋亡率均显著低于UMON组、CON1组和CON2组(均P<0.05),而D1-D6吸光度、S期、G_2/M期和PI均显著高于UMON组、CON1组和CON2组。结论甲基化寡核苷酸可成功诱导DKK3基因甲基化,导致Hep G2肝癌细胞细胞增殖增加而凋亡下降。
