摘要

目的：探讨小泛素相关修饰物(small ubiquitin-related modifier，SUMO)特异性蛋白酶1(SUMO specific protease 1，SENP1)和ERα在I型子宫内膜癌中的表达，并分析两者之间的相互关系。方法：收集I型子宫内膜癌组织及其配对癌旁组织各50例，采用免疫组织化学法检测SENP1蛋白及雌激素受体(ERα)的表达，分析其表达与患者临床病理参数的关系。结果：I型子宫内膜癌中SENP1蛋白在癌旁组织中的表达明显高于肿瘤组织。SENP1蛋白在高分化肿瘤中的表达明显高于低分化肿瘤组织。SENP1阳性表达与ERα表达呈正相关，而与患者的年龄、肿瘤浸润的深度、肿瘤分期及淋巴结转移无关。结论：SENP1在I型子宫内膜癌的发生、发展中发挥重要作用，有望成为治疗子宫内膜癌的新靶点。

Abstract

Objective: To investigate the expression and relationship of SUMO specific protease 1 (SENP1) and ERα in type-1 endometrial carcinoma. Methods: Fifty endometrial cancer cases were involved in this study. Immunohistochemical method was performed to study SENP1 protein and estrogen receptor (ER) expression in endometrial cancer tissues and para-carcinoma tissues. Correlations between SENP1 and ERα, as well as clinical pathological parameters were also analyzed. Results: Expression of SENP1 protein in type-1 endometrial carcinoma was significantly higher than that in the para-cancer tissues. Expression of SENP1 protein was significantly higher in well-differentiated tumors than in poorly-differentiated tumors. Expression of SENP1 was positively correlated with the expression of ERα, but not with the age of patients, the depth of tumor invasion, tumor stage and lymph node metastasis. Conclusion: SENP1 may play an important role in the occurrence and development of type-1 endometrial carcinoma, which may be a new target for the treatment of endometrial carcinoma.
Keywords： endometrial carcinoma SUMO specific protease 1 estrogen receptor immunohistochemistry
