ME491和KAI1基因抗胰腺癌转移作用的评价

Evaluation of the effect of KAI1 gene and ME491 gene suppressing metastasis on pancreatic cancer.

目的探讨不同转移抑制基因ME491和KAI1对胰腺癌抗转移作用的影响。方法2003-11～2004-02在沈阳军区总医院消化内科实验室采用原位杂交法和免疫组织化学技术分别对正常胰腺组织(17例)及胰腺癌组织(50例)中的ME491和KAI1基因及其蛋白表达进行检测。结果ME491和KAI1在胰腺癌组织中的表达高于正常组织,ME491在有转移和没有转移组织中的表达差异无显著性,但KAI1在无转移的组织中的表达高于有转移的组织。结论ME491可能与胰腺癌转移无明显相关,KAI1基因具有明显抗胰腺癌转移作用。

Objective To study the effect of suppressing metastasis between KAI1 and ME491 on pancreatic cancer.Methods Normal pancreases and pancreatic cancers were analyzed using Northern blot,in situ hybridization and immunohistochemistry.Results The expression of KAI1and ME491 was higher in pancreatic cancer than that in normal pancreases,KAI1 expression was higher in pancreatic cancer without metastasis than that in pancreatic cancer with metastasis(P<0.05),ME491 expression in pancreatic cancer without metastasis was as high as that in pancreatic cancer with metastasis(P>0.05).Conclusion The gene of KAI1 may be involved in the metastasis of pancreatic cancer,ME491 gene may have no effect on the metastasis of pancreatic cancer.
