摘要 目的探讨cAMP反应元件结合蛋白(CREB)特异性siRNA对人卵巢癌CAOV3细胞增殖的影响及机制。方法将人卵巢癌CAOV3细胞随机分为3组,实验组按照转染试剂说明书分别转染终浓度50、1001、50 nM的CREB特异性siRNA,阴性对照组仅含等体积的脂质体,空白对照组不予干预,MTT法检测各组细胞增殖抑制率,RT-PCR法及Western blot法检测CREB、cyclin D1表达。结果实验组增殖抑制率明显高于阴性对照组,CREBc、y-clin D1的mRNA及蛋白明显低于阴性对照组,P均<0.05;实验组100 nM、150 nM增殖抑制率均明显高于50 nM,CREB、cyclin D1的mRNA及蛋白明显低于50 nM,P均<0.05。结论 CREB特异性siRNA可有效抑制人卵巢癌CAOV3细胞增殖,其机制可能与CREB和cyclin D1的表达降低有关。
