摘要: 目的探讨TNF受体相关死亡区域蛋白(TRADD)、核因子κB(NF-κB)在乙肝后肝硬化(LC)和原发性肝癌(HCC)中的表达及其临床意义。方法 采用Western blot分别检测35例LC和HCC中TRADD和NF-κB蛋白的表达。采用Fisher精确概率法进行统计分析。结果 TRADD在HCC中表达阳性率为68.6%(24/35), LC中为100.0%(P=0.0002)。NF-κB在HCC中表达阳性率为77.1%(27/35), LC中为100%(P=0.002)。TRADD与HCC患者的甲胎蛋白水平相关(P<0.01)。结论 乙肝后肝硬化中TRADD和NF-κB介导的肝细胞增殖和凋亡处于活跃水平。这种细胞增殖和凋亡信号转导机制的异常可能在肝硬化癌变过程中起着重要作用。

Abstract: Objective To investigate the expression of TRADD and NF-κB in hepatocellular carcinoma and liver cirrhosis after HBV-infected and its clinical significance.Methods Western blot was used to detect the protein expression in 35 HCC and 35 LC cases.The Results were statistically analyzed by Fisher′s exact test.Results Expression of TRADD was found in 24 of 35 cases in HCC and all of 35 cases in LC(P=0.0002).Expression of NF-κB was found in 27 of 35 cases in HCC and all of 35 cases in LC(P=0.002).Expression of TRADD was correlated with the lever of the α-fetoprotein in HCC.Conclusion TRADD and NF-κB might mainly be activated in LC with a long-term HBV infection.The abnormal pathway may play important roles in HBV-induced hepatocyte transformation and carcinogenesis.
