沉默BIRC7基因的Jurkat稳定细胞系建立
【目的】 通过RNA干扰技术(RNAi)建立稳定性BIRC7基因沉默的Jurkat实验细胞模型。 【方法】应用pSilencer 4.1-CMV neo 构建BIRC7 shRNA 表达载体,采用脂质体将载体导入Jurkat 细胞,利用G418筛选出稳定表达shRNA 细胞后,行RT-PCR 和Western blot 等技术检测细胞BIRC7表达水平。 【结果】成功筛选出分别携带二种重组shRNA表达的Jurkat细胞系。与对照组细胞相比,转染BIRC7 shRNA的细胞BIRC7 mRNA表达下降约>70%,BIRC7蛋白表达减少>60%。生长曲线显示生长速度减慢,细胞倍增时间延长。细胞凋...
