    • The inventors have proposed a novel panel of human serum protein biomarkers for diagnosing hepatic fibrosis and cirrhosis. Presently there is no reliable non-invasive way of assessing liver fibrosis. A 2D-PAGE based proteomics study was used to identify potential fibrosis biomarkers. Serum from patients with varying degrees of hepatic scarring induced by infection with the hepatitis C virus (HCV) was analyzed. Several proteins associated with liver scarring and/or viral infection were identified. These proteins include the inter-α-trypsin inhibitor heavy chain H4 fragments, complement factor H-related protein 1, CD5L, Apo L1, and β2GPI. Increased and decreased thiolester cleavage of a2M and Complement C3, respectively, was also detected. The concentrations of these novel biomarkers can be determined using an immunoassay where the concentrations would reflect the extent of fibrosis. A fibrosis scoring scale for each of the novel biomarkers is proposed. The additive result from the scores of all the novel biomarkers would give a more reliable indication of the degree of fibrosis rather than examining individual biomarkers.
    • 本发明人提出了用于诊断肝纤维化和肝硬化的人类血清蛋白生物标志物的新颖小组。 目前尚无可靠的非侵入性肝纤维化评估方法。 使用基于2D-PAGE的蛋白质组学研究来鉴定潜在的纤维化生物标志物。 分析了丙型肝炎病毒(HCV)感染引起肝脏瘢痕形成程度不同的患者血清。 鉴定了与肝脏瘢痕形成和/或病毒感染相关的几种蛋白质。 这些蛋白质包括α-间胰蛋白酶抑制剂重链H4片段,补体因子H相关蛋白1,CD5L,Apo L1和&bgr; 2GPI。 还检测到了分别增加和减少的a2M和补体C3的硫醇裂解。 这些新型生物标志物的浓度可以使用免疫测定来确定,其中浓度将反映纤维化程度。 提出了每种新型生物标志物的纤维化评分量表。 所有新生物标志物的得分的添加剂结果将给出更可靠的纤维化程度的指示,而不是检查个体生物标志物。
