整合素连接激酶在C57小鼠Lewis肺癌中的表达及肺岩宁方对其的调控作用

目的探讨肺岩宁方对整合素连接激酶（integrin-linked kinase.ILK）mRNA及蛋白表达的影响。方法建立C57小鼠Lewis肺癌模型。将C57BL-6纯系10周龄雄性小鼠随机分为正常组、模型组、顺铂（DDP）组、肺岩宁方组,每组10只。正常组正常饲养;模型组以0.9%NaCl溶液0.4ml灌胃;顺铂组在造模后第5天开始给药,在开始给药的第1、3、5天,DDP溶液1ml（含DDP0.1mg）腹腔注射,0.9%NaCl溶液0.4ml灌胃;肺岩宁方组在造模后第5天开始给予肺岩宁方药液0.4ml（生药含量36.1g/kg）灌胃。采用Real time PCR和Western blot方法分别检测ILK在移植瘤组织和转移灶发生的肺组织中mRNA、蛋白水平的表达。结果与正常组比较,模型组肿瘤肺转移率、转移灶及Ilk基因表达差异均有统计学意义（P〈0.01）,说明模型成功。与模型组比较,肺岩宁方组可以显著降低肺转移灶的发生的作用（P〈0.01）。各组移植肿瘤组织中,肺岩宁方组ILK基因表达与模型组比较显著降低（P〈0.01）;各组肺组织中,与模型组比较,肺岩宁方组ILK基因表达显著下降（P〈0.01）,而化疗组ILK基因表达反而升高（P〈0.01）。与模型组比较,肺岩宁方组ILK蛋白的表达明显降低（P〈0.01）。结论肺岩宁具有显著降低ILK基因表达的作用,调控Snail信号途径的关键信号分子ILK基因有可能是肺岩宁方抗肿瘤转移的有效作用靶点所在。

Expression of integrin-linked kinase in C57 mice with Lewis lung cancer and the regulatory effects on it by Feiyanning Decoction

Objective To explore the effect of Feiyanning Decoction on the integrin-linked kinase(ILK)mRNA and protein expressions.Methods Through the establishment of C57 mice with Lewis lung cancer model,real time PCR and Western blot methods were used to detect mRNA and protein expression of ILK both in tumor tissue and lung tissue with metastasis to further elaborate effective target of Feiyanning Decoction for anti-tumor metastasis.Results Compared with model group,Feiyanning Decoction could significantly reduce t...
