摘要:

目的 了解肝细胞癌(HCC)患者外周血单个核细胞(PBMC)人类白细胞抗原G(HLA-G)的表达水平。方法 收集38例HCC患者、25例肝硬化患者和40名健康查体者的PBMC,分别用逆转录-聚合酶链反应(PCR)和流式细胞术(FCM)检测其HLA-GmRNA和HLA-G蛋白表达水平。结果 HCC组、肝硬化组和健康对照组PBMCHLA-GmRNA表达率分别为94.7%、84.0%和87.5%,差异无统计学意义(P=0.359);HCC组HLA-G蛋白表达率高于肝硬化组和健康对照组,差异有统计学意义(P=0.002)。HCC组PBMCHLA-G蛋白主要表达于CD4+细胞上。结论 HCC患者PBMCHLA-G蛋白表达率升高,其机制与临床意义尚待进一步研究。

Abstract:

Objective  To investigate the expression level of peripheral blood mononuclear cell (PBMC) human leucocyte antigen G (HLA-G) in patients with hepatocellular carcinoma (HCC). Methods  The HLA-G mRNA and HLA-G protein expression levels on PBMC from 38 patients with HCC,25 patients with liver cirrhosis and 40 healthy subjects were determined by reverse transcription-polymerase chain reaction (PCR) and flow cytometry (FCM). Results  The HLA-G mRNA expression rates in HCC group,cirrhosis group and healthy control group were 94.7%,84.0% and 87.5%, respectively,and there was no statistical significance (P=0.359). The HLA-G protein expression rate in HCC group was significantly higher than those in cirrhosis and healthy control groups with statistical significance (P=0.002). In HCC group, the HLA-G protein was mainly expressed on CD4+ cells. Conclusions  The PBMC HLA-G protein expression rate in HCC patients increases,and its mechanism and clinical significance need to be further researched.
