Identification of apolipoprotein C-III as a potential plasmatic biomarker associated with the resolution of hepatitis C virus infection
Abstract : Understanding the virus-host interactions that lead to approximately 20% of patients with acute Hepatitis C Virus (HCV) infection to viral clearance is probably a key towards the development of more effective treatment and prevention strategies. Acute hepatitis C infection is usually asymptomatic and therefore rarely diagnosed. Nevertheless, HCV nucleic acid testing carried out on all blood donations detects donors who have resolved their HCV infection after seroconver-sion. Here we have used SELDI-TOF-MS technology to compare, at a proteomic level, plasma samples respectively from donors with HCV clearance, from donors with chronic HCV infection and from unexposed healthy donors (n = 15 per group). A candidate marker of about 9.4 kDa was detected as differentially expressed in the three groups. After purification we identified by nanoLC-Q-TOF-MS/MS this candidate marker as Apolipoprotein C-III (ApoC-III). The identification was confirmed by western blot analysis. Levels of ApoC-III were then determined in the 45 plasma samples by immunoturbidimetric assay. ApoC-III was found to be higher in donors who had resolved their HCV infection than in donors with chronic infection, results which were consistent with SELDI-TOF-MS data. ApoC-III is the first reported candidate biomarker in plasma associated with the spontaneous resolution of HCV infection.
