【摘要】 目的研究半乳糖凝集素-3(Galectin-3)与基质金属蛋白酶-2(MMP-2)、组织基质金属蛋白酶抑制剂-2(TIMP-2)在大肠癌中的表达,并探讨其在大肠癌进展过程中的意义。方法应用免疫组化法检测52例大肠癌组织、20例大肠腺瘤和20例大肠正常黏膜组织中Galectin-3与MMP-2、TIMP-2的表达情况。结果 1 Galectin-3、MMP-2在大肠癌中的阳性表达率最高,而TIMP-2在大肠癌中的阳性表达率最低;2大肠癌组织中,浸润程度深、低分化及有淋巴结转移的Galectin-3、MMP-2的表达明显升高,而TIMP-2的表达则明显降低;3在大肠癌组织中Galectin-3与MMP-2的表达呈正相关,而与TIMP-2的表达呈负相关。结论 Galectin-3、MMP-2与TIMP-2表达的失平衡与大肠癌的浸润和转移密切相关。更多还原

【Abstract】 Objective To study the expression of Galectin-3 and MMP-2, TIMP-2 in colorectal carcinoma, and to investigate its in colorectal cancer progression of meaning in the course. Method To detect the expression of Galectin-3 and MMP-2,TIMP-2 in 52 cases of colorectal cancer, 20 cases of colorectal adenoma and 20 cases of colorectal normal mucosa tissue through the application of immunohistochemistry. Analyzed the relationship between its expression with the patient’s sex, age, tumor location, tumor differentiation, infiltration and lymph node metastasi. Result 1 In colorectal carcinoma, the expression of Galectin-3 and MMP-2 were highest and the expression of TIMP-2 was lowest; 2 In infiltration over the muscle layer of the colorectal carcinoma and in poorly differentiated colorectal carcinoma and in lymph node metastasis of colorectal cancer tissues, the expression of Galectin-3 and MMP-2 were higher and the expression of TIMP-2 was lower; 3 The expression of Galectin-3 and MMP-2 were positive correlation and the expression of Galectin-3 and TIMP-2 were negative correlation in colorectal carcinoma. Conclusion The imbalance expression of Galectin-3, MMP-2 and TIMP-2 is positive corrrelated with the invasion and metastasis of colorectal carcinoma.更多还原
