摘要
为探讨IL-6基因转导对人乳腺癌细胞体内外生长特性的影响,我们构建了含人IL-6cDNA的逆转录病毒载体pLIL6SN。采用脂质体介导的方法将pLIL6SN导入MCF-7细胞中,对基因转导细胞的体外生长、粘附特性及裸鼠体内的实验性转移能力进行了测定。实验结果表明,经IL-6基因修饰的MCF-7细胞虽显示了明显的体外生长抑制,裸鼠体内实验性转移能力却获得增强。
Objective: To investigate the influence of IL6 gene transduction on human mammary carcinoma cell growth both in vitro and in vivo.Method: retroviral vector pLIL6SN which contained human IL6 cDNA was constructed and transferred into MCF7 cell line with the mediation of lipofection.IL6 gene transfectant growth and adhesion potential in vitro was assayed and its metastatic competence in nude mice was examined. The results showed that the growth of IL6 genetransferred MCF7 cell was markedly inhibited in vitro,and that the metastatic potential in vivo was enhanced.
