目的　采用RNA干扰技术沉默CCS（copper chaperone for SOD1）基因，构建相关小干扰RNA（siRNA），探索出针对CCS的高效siRNA序列。方法　合成用于人脐静脉内皮细胞（HUVEC）细胞中沉默CCS基因的siRNA。应用脂质体转染的方法在HUVEC细胞中对CCS基因进行RNA沉默。蛋白免疫印迹Western blotting检测沉默前后CCS蛋白表达变化的情况，甲基四唑蓝法MTT检测转染前后细胞活力。最后用单因素方差分析对数据进行统计学分析，以确定有效的siRNA序列。结果　转染前后细胞形态无肉眼可见变化，转染后细胞活力分别为98.5%和98.8%。CCS蛋白沉默率分别为63.7%和61.4%。结论　采用siCCS-2和siCCS-3序列转染条件对HUVEC细胞活力损伤小，CCS沉默效率高，实验条件稳定，重复性好。为我们继续研究沉默CCS后抑制血管内皮细胞的生长增殖、血管形成提供了稳定的实验基础。
