摘要 目的在结肠癌HT29细胞株基础上获得高转移结肠癌细胞株,并建立高侵袭性结肠癌肝转移的动物模型。方法将结肠癌HT29细胞株通过体内连续传代方法获得高转移结肠癌细胞株,并成功建立高侵袭性结肠癌肝转移的动物模型,采用cDNA-microarray技术比较结肠癌细胞株及高转移细胞株形成的肝转移组织,获得与结肠癌肝转移相关的差异基因。采用荧光定量PCR方法检测亲代细胞和高转移细胞的基因表达。结果建立高侵袭性结肠癌肝转移的动物模型。定量PCR检测显示结肠癌高转移性HT29的酪氨酸激酶受体家族、基质金属蛋白酶家族和细胞周期调控蛋白的基因较亲代HT29细胞均有不同程度的变化。结论结肠癌HT29细胞株及其高侵袭性结肠癌肝转移的动物模型为结肠癌转移的生物学研究提供了一个良好的技术平台。
