| 摘 要： | 目的：研究Ku80基因分子克隆在人肺癌细胞的表达及生物学意义。方法：用分子克隆的方法构建重组的正义，反义Ku80基因表达质粒，导入人肺癌细胞后，用Northern-blotting法和Western-blotting法证明Ku80正义，反义基因在mRNA和蛋白水平的表达情况。结果：（1）正义或反义Ku80克隆阳性的LCA细胞在mRNA水平均有正义或反义Ku80的表达印迹。（2）仅在正义Ku80克隆阳性的LCA细胞有正义Ku80蛋白表达印迹而反义Ku80克隆阳性的LCA细胞无Ku80蛋白表达印迹，结论：正义或反义Ku80基因的分子克隆可在人肺癌细胞的mRNA得到表达，正义Ku80克隆阳性的LCA细胞有正义Ku80蛋白表达，反义Ku80基因可封闭肿瘤细胞的正义Ku80蛋白的表达，此结论为将Ku基因作为肿瘤靶向基因治疗提供了实验依据。 |

| Abstract: | Abstract Objective:To study the expression and its biologic specification of the Ku80 gene molecular cloning.Methods: Constructingrecombinant sense or antisense Ku80 expression vectors (Ku80/pCAGGS) and transferring into LCA .Those Ku80 mRNA and protein were de-teited in the Ku80s-LCA, Ku80as-LCA and by Northern-blotting and or Western-blotting.Results: Those Ku80 mRNA were detected in the Ku80s-LCA and Ku80as-LCA by Northern-blotting. Only the sense Ku80 protein was defected in the Ku80s-LCA , but wasn' t detected in the Ku80as-LCA by Western-blotting.Conclusion:The sense or antisense Ku80 were not only transferred in to LCA ,but also expressed in the mR-NA . Only the sense Ku80 protein was expressed in the Ku80s-LCA , but wasn' t expressed in the Ku80as-LCA . The Ku80 is a candidate tar-get for cancer gene therapy. |
