整合素连接激酶在胰腺癌中的表达及意义

目的 探讨整合素连接激酶(intergrin linked kinase,ILK)在胰腺癌组织中的表达及其临床意义.方法 采用免疫组织化学法和Western blotting法检测ILK在60例胰腺癌和32例癌旁正常胰腺组织中的表达,并分析其与临床病理参数的关系.结果 免疫组化结果显示,ILK蛋白在胰腺癌细胞胞质内和胞膜上以及间质中均有表达,其阳性表达率为65.0%(39/60),显著高于正常胰腺组织的18.8%(6/32,P＜0.05).Western blotting结果显示,ILK在胰腺癌组织中的相对表达量为303933±195116,显著高于正常胰腺组织的144613±30074(P＜0.05).在胰腺癌组织中,ILK表达与肿瘤的临床分期和淋巴结转移有关(P＜0.05),而与肿瘤分化程度无关.结论 ILK在胰腺癌组织高表达,并与肿瘤的恶性程度相关.

Expression and significance of integrin linked kinase in pancreatic carcinoma

Objective To investigate the expression and clinical significance of intergrin linked kinase (ILK) in pancreatic carcinoma.Methods ILK protein was detected by immunohistochemistry and Western blotting in 60 cases of pancreatic carcinoma and 32 cases of normal pancreatic tissue,and the relationship with the clinicopathological characteristics were analyzed.Results Immunohistochemistry showed ILK was expressed in cytoplasm and membrane of pancreatic carcinoma cells and the positive rate was 65% (39/60),which was significantly higher than 18.75% (6/32) of normal pancreatic tissue(P ＜0.05 ).Western blotting showed the expression of ILK in pancreatic carcinoma tissue was 303933±195116,which was significantly higher than 144613±30074 of normal pancreatic tissue(P＜0.05 ).In pancreatic carcinoma,the expression of ILK was correlated with clinical stage and lymph metastasis(P＜0.05 ),but not correlated with tumor cell differentiation(P＞0.05 ).Conclusions ILK protein was highly expressed in pancreatic carcinoma tissue and it was correlated with the degree of malignancy.
