肝细胞癌是世界范围内一种主要的致命性癌症,由肝脏中不同的病因引起。目的:了解不同病因的肝细胞癌患者的血清蛋白质谱。我们用双向凝胶电泳法(2-DE)和液质联用法(LC-MS/MS)对乙肝病毒感染者、丙型肝炎病人、非乙型非丙型肝癌患者和健康志愿者的血清进行了检测。我们在两次分析中发现了30个差异表达的蛋白质点(≥1.5倍P<0.05),其中17个蛋白质点对应于8个蛋白质的转甲素、富含亮氨酸的α-2-糖蛋白和非B非C-肝细胞癌血清之间的差异表达。此外,结合珠蛋白α-2亚型在丙型肝炎肝细胞癌中的表达明显低于非乙型非肝细胞癌。不同来源肝细胞癌的血清蛋白质组学分析显示,不同来源的肝细胞癌的蛋白质图谱存在差异,这可能与不同诱因诱导的肝细胞癌的肝脏病理机制不同有关。需要进一步的研究来阐明识别的蛋白质对不同来源的肝细胞癌早期诊断的重要性。
Hepatocellular carcinoma (HCC), a major fatal cancer worldwide, is induced by different etiological factors in the liver. To gain insight into serum protein profiling of HCC with different etiologies. We subjected the sera of HBV-HCC, HCV-HCC, non-B non-C-HCC patients, and healthy volunteers to two-dimensional gel electrophoresis (2-DE) and liquid chromatography tandem mass spectrometry (LC-MS/MS). We found 30 differentially expressed protein spots (≥ 1.5 fold P < 0.05) between these two analyses; of them 17 protein spots corresponding to 8 proteins were identified by MS. Transthyretin, leucine rich α-2-glycoprotein, and ficolin 3 were differentially expressed between HBV-related HCC and non-B non-C-HCC sera. Moreover, haptoglobin α-2 isoforms were decreased in HCV-HCC compared to non-B non-CHCC. Serum proteome analyses of HCC with different origins showed a differential protein pattern, presumably related to different hepatopathogenesis in liver induced by different agents. Further studies are required to clarify the importance of identified proteins for early diagnosis of HCC with different origins.
