中文摘要:
      目的:沉默UVRAG 基因在DADS诱导细胞中观察caspase3的表达。方法:以细胞为细胞模型,将构建成功并 筛选出最有效干扰抑制UVRAG基因的siRNA序列片段采用lipofectamine TM2000 脂质体转染法转染白血病细胞, 组别 为:空白对照组,转染试剂组、阴性对照组,阳性对照组,转染24 小时后,利用QT-PCR检测UVRAG mRNA的表达水平以此观察 干扰效果,再以40 mg/LDADS处理转染试剂组12 小时,采用蛋白印迹(Western Blotting)技术检测凋亡相关基因caspase3 的表 达。结果:QT-PCR 显示:与空白组相比,UVRAG mRNA表达明显减少,表明沉默UVRAG 基因成功;Western Blotting显示:DADS 处理的干扰成功的细胞12小时后,检测到caspase3 的蛋白表达水平下降。结论:沉默UVRAG 基因能使白血病细胞 中凋亡相关基因caspase3的蛋白表达水平下降,提示抑制UVRAG 表达的同时也可能抑制DADS 诱导细胞的凋亡。
英文摘要:
      Objective:DADS induced the cells in order to observe the expession of caspase3 through silencing UVRAG genes.Methods:The study choose cells for cell model,successfully constructed and selected the most effective gene sequence fragments of siRNA about the gene of UVRAG tranfect to the cells using lipofectamine TM2000-liposomal. There are divided into control group,transfection reagent group,negative control group,positive control group, The interference effection is observed by the QT-PCR detecting the expression levels of UVRAG mRNA after 24 hours transfection, then using 40 mg/LDADS effects the group of transfection 12 hours. Western blotting is used to detect the expression of caspase3 protein induced cell apoptosis.Results:compared with the blank group, the UVRAG mRNA expression levels were lower ,it shows the silence of UVRAG successfully, transferred siRNA-UVRAG of cells in 24 hours,the protein levels of caspase3 is decreased.Conclusion:The protein expression of apoptosis-related genes caspase3 is declined through silencing the UVRAG genes in leukemia cells,it confirmed that inhibition the expression of UVRAG may inhhibit the occurrence of apoptosis of cells.
