针对人IKKα、IKKβ基因RNA干扰慢病毒质粒的构建及其对人肝癌细胞生长的影响
Jiangsu Medical Journal(2009)
Abstract
目的构建人IKKα、IKKβ基因RNA干扰慢病毒质粒,并观察其对肝癌细胞生长的影响。方法将目的片段亚克隆入慢病毒载体中,包装成病毒后感染人肝癌细胞,检测细胞IKKα、IKKβ的表达,并将感染细胞接种于裸鼠皮下,观察肿瘤生长情况。结果目的片段被成功克隆入载体质粒。pLenti-GFP-IKKα-SiRNA慢病毒液感染的细胞中IKKα蛋白表达明显降低,pLenti-GFP-IKKβ-SiRNA慢病毒液感染的细胞中IKKβ蛋白表达明显降低。实验组裸鼠皮下肿瘤出现晚且生长缓慢。结论成功构建了针对人IKKα、IKKβ基因RNA干扰慢病毒质粒,包装成病毒后感染人肝癌细胞后能抑制其生长。
