摘要: 目的: 探讨在新疆哈萨克族食管癌组织中miR-143、基质金属蛋白酶-2(MMP-2) 和基质金属蛋白酶抑制剂-1(TIMP-1)的表达及其临床意义。方法: 根据前期芯片检测结果,通过靶点预测软件PicTar TargetScan和miRanda预测miR-143可能与肿瘤相关的靶基因。并采用实时荧光定量PCR方法检测30例哈萨克族食管癌组织及相应癌旁组织中miR-143、MMP-2和TIMP-1的表达水平,分析其与临床病理特征的关系。结果: miR-143在哈萨克族食管癌组织中表达较远端癌旁组织中明显降低,差异有统计学意义(P=0.000);miR-143低表达与分化程度、淋巴结转移、临床分期相关(P依次为0.042、0.039、0.007);MMP-2、TIMP-1在哈萨克族食管癌组织中表达均较远端癌旁组织中增高,差异均有统计学意义(P=0.026和P=0.021);MMP-2高表达与淋巴结转移正相关(r=0.367 P=0.037);miR-143与MMP-2、TIMP-1的表达均呈负相关(r依次为-0.442、-0.410,P均<0.05),MMP-2与TIMP-1的表达呈正相关(r=0.794,P=0.000)。结论: miR-143与MMP-2、TIMP-1表达失调共同参与哈萨克族食管癌的发生发展过程,MMP-2和TIMP-1可能是miR-143的靶基因。

Abstract: OBJECTIVE: To study expressions of miR-143,matrix metalloproteinase-2(MMP-2) and tissue inhibitor of metalloproteinase-1(TIMP-1) in esophageal cancer tissue and normal tissue among Kazaks and to investigate the relationship between their expressions and clinical pathological features. METHODS: Using real time-PCR to detect the expression of miR-143,MMP-2 and TIMP-1 in 30 esophageal cancer specimens. RESULTS: The expression levels of miR-143 in cancer tissue were lower than those of normal tissues(P=0.000).The lower expression of miR-143 was significantly related to the cellular differentiation lymph node metastasis and clinical stage (P=0.042,0.039 0.007).The expression levels of MMP-2,TIMP-1 in cancer tissue were higher than those of normal tissues(P=0.026 0.021).Enhanced expression of MMP-2 was significantly related to lymph node metastasis(r=0.367,P=0.037).The expression of miR-143 in the Kazak's esophageal cancer was negatively related to the expressions of MMP-2 and TIMP-1 (r=-0.442,-0.410; P=0.001,0.003).The expression of MMP-2 positively related to that of TIMP-1(r=0.794,P= 0.000). CONCLUSION: The under-expression of miR-143 and over-expressions of MMP-2 and TIMP-1 may have important roles in carcinogenesis of esophageal cancer in Kazaks.
