中文摘要：

目的:分析正常和肿瘤组织中ZNF165的表达及其在肝癌患者体内诱导产生的自发性体液免疫反应。方法:采用RT-PCR和定量PCR方法检测16种正常和4种肿瘤(肝癌、胃癌、结肠癌、肺癌)组织中ZNF165mRNA及表达丰度;将ZNF165基因在原核细胞中进行蛋白表达,亲和层析法纯化重组ZNF165蛋白。Westernblot方法对ZNF165在82例肝癌患者体内诱导的自发性抗体进行检测。结果:正常组织中ZNF165mRNA只在睾丸组织表达,肝癌、胃癌、结肠癌和肺癌组织中ZNF165mRNA阳性率分别为52.4%、42.8%、42.8%和21.4%。定量PCR结果显示ZNF165mRNA以高水平在肝癌组织与睾丸组织中表达,而在配对的癌旁组织与其他正常组织中仅存在很低水平的表达(P均<0.01)。82例肝癌患者血清中4例与ZNF165蛋白出现免疫反应,阳性率4.9%;36例正常人血清均为阴性。结论:ZNF165是一个新的肿瘤-睾丸抗原基因,它在机体内可诱导体液免疫反应,有可能作为肿瘤免疫治疗的候选抗原。

英文摘要：

Aim:To study ZNF165 expression in normal and tumor tissues and spontaneous humoral immunoresponse elicited by ZNF165 in liver cancer patients.Methods:ZNF165 mRNA and its quantity were measured in normal and tumor tissue by RT-PCR and quantitative PCR.Recombinant ZNF165 protein was expressed in prokaryotic cells and purified with affinity chromatography.Spontaneous antibody induced by ZNF165 in sera of liver cancer patients was detected by Western blot.Results:In normal tissues,ZNF165 mRNA only expressed in ...
