Abstract

Biomarkers of hepatitis B virus (HBV) infection, aflatoxin B1 (AFB1) exposure and oxidative stress were detected in 71 hepatocellular carcinoma (HCC) patients and 694 controls from southern China. Plasma level of AFB1-albumin-adducts (AAA) and protein carbonyl content (PCC) were significantly higher in the 71 HCC cases than in any age/gender matched HBV sero-status groups (p<0.001). HCC patients positive for the p53-249 G-T mutation had a marginally higher level of PCC than those negative for the mutation (p=0.077). HBV infection had a prominent influence on the association between AFB1 exposure and oxidative stress biomarkers in the controls. Our study indicates a significant contribution from HBV infection to oxidative stress in a population with AFB1 exposure which might substantially increase risk for HCC in this region.

摘要

在中国南方的71例肝细胞癌(HCC)患者和694例对照中检测了乙肝病毒(HBV)感染、黄曲霉毒素B1(AFB1)暴露和氧化应激的生物标志物。71例HCC患者的血浆AFB1-白蛋白加合物(AAA)水平和蛋白质羰基含量(PCC)显著高于任何年龄/性别匹配的HBV血清学状态组(p<0.001)。p53-249 G-T突变阳性的HCC患者的PCC水平略高于突变阴性患者(p=0.077)。HBV感染对对照组中AFB1暴露与氧化应激生物标志物之间的关联有显著影响。我们的研究表明,在AFB1暴露人群中,HBV感染对氧化应激有显著贡献,这可能会大幅增加该地区HCC的风险。
