摘要 目的:通过抑制水通道蛋白-1在前列腺癌PC-3细胞的表达,了解前列腺癌细胞的凋亡情况。方法:设计合成针对前列腺癌PC-3细胞AQP1基因的小干扰RNA并构建高效表达载体,脂质体法转染PC-3细胞,Western Blot检测AQP1蛋白表达的变化。结果:AQP1在前列腺癌PC-3细胞表达,针对AQP1基因siRNA高效表达载体能够抑制AQP1蛋白在PC-3细胞的表达,AQP1蛋白相对表达量为:转染组0.54±0.04,正常对照组0.82±0.08,差异有显著性(P<0.01);成瘤实验中转染组caspase-3的含量明显高于对照组,差异显著(P<0.05),AQP1的表达量与癌细胞的凋亡呈负相关。结论:通过抑制AQP1基因的表达,有效抑制了前列腺癌PC-3细胞AQP1蛋白表达,近而使癌细胞的凋亡增加。
