摘要 目的探讨免疫抑制分子人类白细胞抗原G(HLA-G)在卵巢恶性肿瘤组织中的表达及其临床意义。方法采用免疫组织化学SP法,应用抗HLA-G单克隆抗体4H84,检测45例原发性卵巢恶性肿瘤和36例卵巢良性肿瘤组织中HLA-G蛋白的表达。应用逆转录酶聚合酶链式反应(RT-PCR)法分析新鲜卵巢良、恶性组织中HLA-G mR-NA的表达。结果①免疫组织化学显示,30例卵巢恶性肿瘤组织中有HLA-G的表达阳性(66.67%),HLA-G在卵巢恶性肿瘤组织中的表达明显高于良性组织(P<0.01);②浆液性囊腺癌、粘液性囊腺癌、子宫内膜样癌间HLA-G分子的阳性率差异有统计学意义(P<0.05),HLA-G阳性率与年龄、临床分期、病理分级、淋巴结转移无关;③RT-PCR结果表明卵巢恶性肿瘤组织中有HLA-G mRNA的表达,而卵巢良性肿瘤及卵巢瘤样病变组织中则无HLA-GmRNA的表达。结论卵巢恶性肿瘤组织中HLA-G mRNA及HLA-G蛋白的表达异常,提示在卵巢恶性肿瘤的发生发展中免疫抑制起到重要作用。 Objective To evaluate expression of human leukocyte antigen-G(HLA-G),an important immunosuppressive molecule,in ovarian malignant tumor tissues and to explore its clinical significance.Methods HLA-G expression in 36 benign ovarian tumor tissues and 45 primary ovarian malignant tumor tissues were analyzed using SP immunohistochemical method with the anti-HLA-G monoclonal antibody 4H84.Also,we used RT-PCR to determine expression of HLA-G mRNA in fresh ovarian malignant and benign ovarian tumor tissues.Results...
