摘要
目的:探讨在新疆哈萨克族食管癌组织中基质金属蛋白酶1、2、7(MMP-1、MMP-2、MMP-7)、基质金属蛋白酶抑制因子1(TIMP-1)和肿瘤转移相关基因1(MTA1)mRNA的表达及其临床意义。方法:采用RT-PCR方法检测75例哈萨克族食管癌标本中MMP-1、MMP-2、MMP-7、TIMP-1和MTA1 mRNA的表达水平,分析其表达与临床病理特征的关系。结果:MMP-1、MMP-2、MMP-7、TIMP-1和MTA1 mRNA在哈萨克族食管癌组织中的表达较正常组织增高,差异均具有统计学意义(P均<0.05);且MMP-2、MMP-7、MTA1 mRNA的表达与淋巴结转移有关(P<0.05),MMP-1、MMP-7 mRNA的表达与临床分期有关(P<0.05);TIMP-1与MMP-1、MMP-7、MTA1的表达呈正相关(r=0.446、0.458、0.333,P均<0.01)。结论:MMP-1、MMP-2、MMP-7、TIMP-1和MTA1 mRNA表达上调共同参与了哈萨克族食管癌的发生发展过程;MMP-2、MMP-7和MTA1可能是哈萨克族食管癌发生侵袭、转移的主导因素。
OBJECTIVE:To study expressions of matrix metalloproteinasel,2,7(MMP-1,MMP-2,MMP-7),tissue inhibitor of matrix metallo proteinase 1(TIMP-1)and metastasis associated gene 1(MTA1)in esophageal cancer tissue and normal tissue among Kazaks and to investigate the relationship between their expressions and clinical pathological features.METHODS:Using RT-PCR to detect the expressions of MMP-1,MMP-2,MMP-7,TIMP-1 and MTA1 in 75 esophageal cancer specimens.RESULTS:The mRNA expressions of MMP-1,MMP-2,MMP-7,TIMP-1 and MTA1 in cancer tissue were higher than those of normal tissues(P0.05).While the expression levels of MMP-2,MMP-7 and MTA1 mRNA were significantly related to the lymph node metastasis.The expression levels of MMP-1,MMP-7 mRNA were significantly related to the TNM stages(P0.05).The expression of TIMP-1 in the Kazak's esophageal cancer was positively related to the expressions of MMP-1,MMP-7,MTA1(r=0.446,0.458,0.333,respectively,P0.01).CONCLUSION:The overexpressions of MMP-1,MMP-2,MMP-7,TIMP-1 and MTA1 gene could have important roles in carcinogenesis of esophageal cancer in the Kazaks.Their synergistic effect could promote carcinogenesis and development of esophageal cancer.The MMP-2,MMP-7 and MTA1 genes may be the main players of progression and metastasis in esophageal cancer among Kazaks.
