背景 越来越多的证据表明泛素蛋白酶体系统 (UPS) 的成员对于肿瘤发生很重要。 HERC4 是最近发现的一种泛素连接酶的一个组成部分。然而,HERC4在肺癌中的表达水平和功能作用仍不清楚。我们的目的是研究 HERC4 与肺癌发展之间的相关性及其临床意义。 材料和方法 为了确定肺癌中 HERC4 的表达,对包含 10 个正常肺组织、15 个肺神经内分泌癌、45 个鳞状上皮癌和 50 个腺癌样本的组织微阵列进行了免疫组织化学分析。应用受试者工作特征(ROC)曲线分析获得52.5%的截止点,高于该值则认为HERC4的表达为“阳性”。 结果 ROC曲线分析显示,HERC4阳性表达率在肺正常组织中为0/10(0.0%),在肺神经内分泌癌中为4/15(26.7%),在鳞状上皮癌中为13/45(28.9%),在腺癌中为19/50(38.0%)。结果表明,肺部肿瘤比邻近正常组织表达更多的HERC4蛋白(χ2=4.675,p=0.031)。此外,HERC4阳性表达与pT状态(χ2=44.894,p=0.000)、pN状态(χ2=43.628,p=0.000)、组织学分级(χ2=7.083,p=0.029)和临床分期(χ2=72.484,p=0.000)呈正相关,但与年龄(χ2=0.910,p=0.910)呈正相关。 p=0.340)。 结论 我们的分析表明 HERC4 可能是肺癌的诊断生物标志物。
BACKGROUND Growing evidence suggests that the members of the ubiquitin-proteasome system (UPS) are important for tumorigenesis. HERC4, one component, is a recently identified ubiqutin ligase. However, the expression level and function role of HERC4 in lung cancer remain unknown. Our objective was to investigate any correlation between HERC4 and development of lung cancer and its clinical significance. MATERIALS AND METHODS To determine HERC4 expression in lung cancer, an immunohistochemistry analysis of a tissue microarray containing samples of 10 lung normal tissues, 15 pulmonary neuroendocrine carcinomas, 45 squamous epithelial cancers and 50 adenocarcinomas was conducted. Receiver operating characteristic (ROC) curve analysis was applied to obtain a cut-off point of 52.5%, above which the expression of HERC4 was regarded as "positive". RESULTS On the basis of ROC curve analysis, positive expression of HERC4 was detected in 0/10 (0.0%) of lung normal tissues, in 4/15 (26.7%) of pulmonary neuroendocrine carcinomas, in 13/45 (28.9%) of squamous epithelial cancers and in 19/50 (38.0%) of adenocarcinomas. It showed that lung tumors expressed more HERC4 protein than adjacent normal tissues (χ2=4.675, p=0.031). Furthermore, HERC4 positive expression had positive correlation with pT status (χ2=44.894, p=0.000), pN status (χ2=43.628, p=0.000), histological grade (χ2=7.083, p=0.029) and clinical stage (χ2=72.484, p=0.000), but not age (χ2=0.910, p=0.340). CONCLUSIONS Our analysis suggested that HERC4 is likely to be a diagnostic biomarker for lung cancer.
