摘要: 目的: 研究泛素连接酶hrd1(hydroxymethylglutaryl reductase degradation 1,hrd1)在胃癌及癌旁组织中的表达水平,以此探讨hrd1在胃癌发生发展中的意义。方法: 收集临床胃癌组织及距癌灶边缘 5 cm 以上胃壁组织,应用免疫组织化学SP法研究63例胃癌(实验组)及其癌旁正常组织(对照组)中hrd1蛋白的表达水平,应用荧光定量PCR(Q-PCR)方法分别检测实验组及对照组hrd1基因表达水平,并用统计学方法分析hrd1表达水平与胃癌临床病理参数之间的关系。结果: 免疫组化及Q-PCR结果均显示,胃癌组织中hrd1表达水平明显高于癌旁正常组织,差异有统计学意义(P<0.05)。hrd1在癌灶≥5 cm 的胃癌组织中表达水平高于癌灶<5 cm 的胃癌组织,差异有统计学意义(P<0.05);胃癌组织中hrd1的表达与肿瘤浸润深度、分化程度、淋巴结有无转移和临床分期均无关(P>0.05)。结论: 泛素连接酶hrd1在胃癌组织中表达明显高于癌旁正常组织,提示hrd1可能与胃癌的发生有关。

Abstract: AIM: To investigate the expression of ubiquitin ligase hrd1 expressed in human gastric carcinoma, and discuss its significance in the occurrence and development of gastric carcinoma.METHODS: Collect the samples of gastric carcinoma and the tissue 5 cm from the edge of the cancer, research the expressions of hrd1 protein in normal human cells and gastric carcinoma cells by using immunohistochemical SP method and Q-PCR. Then use statistical methods to analyze the relationship between hrd1 expression and clinicopathological parameters of gastric cancer.RESULTS: Expression level of hrd1 protein was significantly higher in human gastric carcinoma cells than that in normal human cells (P<0.05). The lesions which has a larger size (≥5 cm) has a higher expression of hrd1 than the lesions which has a smaller size (<5 cm, P<0.05). But not with histologic grade and lymph node metastasis (P>0.05).CONCLUSION: Ubiquitin ligase hrd1 may play a role in the occurrence and development of human gastric carcinoma.

Key words: gastric carcinoma, ubiquitin-proteasome system, ubiquitin ligase
