MAP1LC3B 在结肠癌组织中的表达阳性率为72.5%,高于癌旁正常组织(30%),差异有统计学意义(P <0.05)。MAP1LC3B 在结肠癌组织中表达阳性组的肝转移发生率、淋巴结转移发生率高于阴性组,差异均有统计学意义(均P <0.05);两组TNM 分期、分化程度比较差异均无统计学意义(均P >0.05)。结论自噬相关蛋白MAP1LC3B 在结肠癌组织的表达高于癌旁正常组织,与结肠癌肝转移、淋巴结转移的发生有关。[关键词]结肠癌;自噬;MAP1LC3B

[Abstract ]Objectives To investigate the expression and clinical relevance of autophagy-related protein MAP1LC3B in colon cancer.Methods Colon cancer tissues and adjacent normal tissues from 40colon cancer patients who underwent surgery at our hospital between January 2018and June 2020were analyzed.Immunochemistry was used to determine the expression of MAP1LC3B.We analyzed the relationship between MAP1LC3B expression and patients ’clinicopathological characteristics.Re-sults The positive rate of MAP1LC3B expression in colon cancer tissues was 72.5%,which was significantly higher than that in the adjacent normal tissues (30%,P <0.05).Patients in the group with MAP1LC3B expression had a significantly higher rate of liver metastasis and lymph node metastasis than patients in the group without expression (P <0.05).TNM stage and differentiation did not differ between the two groups of patients (P >0.05).Conclusion The expression of autophagy-related protein MAP1LC3B increased in colon cancer tissues,and it was related with liver metastasis and lymph node metastasis.[Keywords ]colon cancer,autophagy,MAP1LC3B

(microtubule-associated protein 1light chain 3be⁃ta ,MAP1LC3B )是调节自噬活性和鉴定自噬水平的
关键基因,是自噬体模型的标志物,其水平的高低反映出细胞自噬活性的强弱[2]。但自噬相关蛋白MAP1LC3B 是否介导了结肠癌患者早期肝转移、淋巴结转移的发生,以及自噬活性的强弱与结肠癌的恶性生物学行为的关系如何,目前尚无明确研究报道。本研究拟探讨MAP1LC3B 在结肠癌中的表达以及它与结肠癌发生发展的关系,现报告如下。1材料与方法1.1一般资料本研究采用回顾性研究方法,对2018年1月至2020年6月在本院接受手术的结肠癌患者癌组织标本40例及癌旁正常组织标本40例(术中取材位456
