Objective To explore livin, MTA1 and the caspase3 protein expression, their correlation and clinical pathology in colon cancer Methods The expressions of livin, MTA1 and caspase3 protein in 88 cases of colon cancer were detected by immunohistochemistry stainingResults Livin, caspase3 protein and MTA1 positive expression rates in colon cancer tissues were more than those in tissues beside the cancer Furthermore there were obvious relevance between livin protein, MTA1 positive expression rate and degree of histodifferentiation and lymph node metabasis and between caspase3 protein positive expression rate and degree of histodifferentiation of colon cancer Caspase3 protein expression had prominent inverse correlation with the livin expressionConclusions ①Over expression of livin having inhibtion on colon cancer is one of important factors of colon carcinogenesis ②Caspase3 protein expression in colon cancer tissues is inhibited to less and has prominent inverse correlation with livin expression Accordingly, suppressing caspase3 protein activity is one of channels, by which livin promotes colon carcinogenesis ③MTA1 plays the important role in histodifferentiation degree and lymph node metastasis of colon cancer

采用免疫组织化学染色方法检测88例结肠癌组织中Livin，Caspase3 及MTA1的表达情况。结果（1）结肠癌组织中Livin的阳性表达率显著高于癌旁组织，且Livin的表达与结肠癌的组织分化程度及淋巴结转移程度显著相关。（2）结肠癌组织中Caspase3蛋白的阳性表达率显著高于癌旁组织，且Caspase3蛋白的表达与结肠癌的组织分化程度显著相关。（3）结肠癌组织中MTA1的阳性表达率显著高于癌旁组织，且MTA1的表达与结肠癌的组织分化程度及淋巴结转移程度显著相关。（4）Caspase3蛋白的表达又与Livin的表达呈显著负相关。结论（1）Livin在结肠癌组织中过表达，它可能是促进结肠癌发生的重要因素之一。（2）Caspase3蛋白在结肠癌组织中表达被抑制而降低，且与Livin的表达呈负相关。因此，抑制Caspase3蛋白的活性是Livin促进结肠癌发生的途径之一。（3）MTA1对结肠癌的组织分化及淋巴转移发挥重要作用。
