摘要
为探讨mdr- 1 、CD44v 和nm23 - H1 基因产物蛋白与肝癌侵袭、转移预后的关系。用免疫组织化学技术检测46 例肝癌患者CD44v 和nm23 - H1 和mdr- 1 基因蛋白的表达。结果显示肝癌组织mdr- 1 、CD44v 和nm23 - H1(60-08 % ) ,明显高于正常组织和癌旁组织( P< 0-05) ;肝癌转移组的mdr- 1 、CD44v 阳性表达率高于nm23 - H1 阳性表达率,差异显著( P< 0-05) ;肝癌非转移组的nm23 - H1 阳性表达率显著高于mdr- 1 、CD44v 阳性表达率( P< 0-05) 。肝癌转移组mdr- 1 、CD44v 明显高于非转移组,而nm23 - H1 则反之( P< 0-05) 。肝癌的侵袭、转移及预后可能与mdr- 1 、CD44v 和nm23 - H1 三种基因产物的异常表达有关。
To probe the relationship betwwen the gene products of mdr 1,CD44v,nm23 H1 and inva sion,prognosis and metastasisin liver carcinoma-The expression of mdr 1 ,CD44v and nm23 H1 in 46 cases of liver carcinoma were studied by im munohistochemitry-Results:mdr 1 ,CD44v and nm23 H1 were expressed at a higherlevelinlivercarcinoma than that mormaland pericarcinomatoustissues( P< 0-05) ,and Theexpression of mdr 1 and CD44v werestrongerthan thatofnm23 H1 in metastasis( P< 0-05)-The expression of nm23 H1(73-33 % )were markly stronger than those of mdr 1 and CD44v in no metastasis( P< 0-05)-The three gene productsin metastasis were markly differentthan thosein no metastasis( P< 0-05)-Conclution :Theabnormalexpression of mdr 1 ,CD44v and nm23 H1 wererelated toinvasion ,metastasis and prognosis ofliver cancer-
