摘要: 通过稳定、高效、低毒的基因转染方法将nm23-H1基因导入该基因缺失的人肺大细胞癌株L9981,从基因及蛋白水平鉴定nm23-H1基因转染肺癌细胞的建立。 方法 : 以JM109为宿主菌,转化质粒载体PCMV-neo-Bam- nm23-H1,制备nm23-H1 基因的真核表达载体;利用阳离子脂质体Lipofectamine介导,将nm23-H1基因导入L9981细胞株。采用RT-PCR技术检测转染后nm23-H1基因的表达,并用Western blot技术检测转染后nm23-H1蛋白的表达。 结果: 转染后的L9981细胞株中可检测到nm23-H1 mRNA及nm23-H1蛋白的阳性表达。 结论: 建立表达nm23-H1基因的肺癌细胞株L9981,为研究nm23-H1对肺癌恶性转移表型的逆转作用作基础准备。

Abstract: nm23-H1 gene was transfected into nm23-H1 deletion human large lung cancer cell L9981 by stable,continuous and high effective gene transfection method. METHODS: nm23-H1 gene expression carrier was established, nm23-H1 was transfected in L9981 cell line and the expression of nm23-H1 was confirmed by gene transduction and protein translation. RESULTS: Transfected cell line showed nm23-H1 gene and protein expressions. CONCLUSION: The expression of nm23-H1 by L9981 cell line provides support for utilizing nm23-H1 as a potential therapy in lung cancer.
