摘要 目的:探讨膜型基质金属蛋白酶-1(MT1-MMP)在非小细胞肺癌(NSCLC)组织中的表达和NSCLC侵袭进展的关系。方法:选择89例NSCLC患者标本,利用原位杂交和免疫组化方法分别检测NSCLC组织中的MT1-MMP mRNA和蛋白水平。结果:在NSCLC组织中MT1-MMP mRNA和蛋白强染区域超过50%的比例分别为43.8%、25.8%。根据临床病理分析发现MT1-MMP mRNA和肿瘤转移情况之间呈显著正相关(r=0.964,P=0.021),MT1-MMP蛋白与病理分期、分型、淋巴结累及或转移无明显相关性,在正常肺组织当中,MT1-MMP mRNA和蛋白的染色活性介于低到中度之间。结论:根据临床病理分析发现MT1-MMP mRNA和肿瘤转移情况之间显著正相关,而MT1-MMP蛋白与病理分期、分型、淋巴结累及或转移无明显相关性。MT1-MMP作为检测肿瘤转移靶点的作用是有限的,它可能通过其他途径与其他底物作用从而在肿瘤转移进程中起作用。
