Serum proteomic profiling in patients with advanced Schistosoma japonicum-induced hepatic fibrosis

ABSTRACT: Background: Schistosoma japonicum (S. japonicum) is a parasitic flatworm that is the aetiological agent of human schistosomiasis, an important cause of hepatic fibrosis. Schistosomiasis-induced hepatic fibrosis is a consequence of the highly fibrogenic nature of egg-induced granulomatuous lesions, the main pathogenic factor of schistosomiasis. Although global awareness of the association between schistosomiasis-indued hepatic fibrosis and s. japonicum infection is increasing, little is known about the molecular differences associated with rapid progression to schistosomiasis in cirrhotic patients. Methods: We systematically used data-independent acquisition (DIA)-based liquid chromatography-mass spectrometry to identify differentially expressed proteins in serum samples from patients with advanced S. japonicum-induced hepatic fibrosis. Results: On the basis of our analysis, we identified 1,144 proteins, among which 66 were differentially expressed between the healthy control and SHF-F2 groups and 214 were differentially expressed between the SHF-F2 and SHF-F4 groups (up- or downregulation of at least 1.5-fold in serum samples). Furthermore, our results indicated that two selected proteins (C1QA and CFD) are potential biomarkers for distinguishing patients with SHF-F2 and SHF-F4 resulting from S. japonicum infection. Conclusions: This report is the first to provide a global proteomic profile of serum samples from patients with advanced S. japonicum-induced hepatic fibrosis. C1QA and CFD are potentially diagnostic markers for patients with SHF-F2 and SHF-F4 resulting from S. japonicum infection, although further large-scale studies are needed. Our DIA-based quantitative proteomic analysis revealed molecular differences among individuals with different stages of advanced S. japonicum-induced hepatic fibrosis and might provide fundamental information for further detailed investigations.

Project description:In schistosomiasis japonica, the egg-induced granulomatous response and the development of extensive hepatic fibrosis is the main pathology. Information regarding the specific mechanisms associated with granuloma regression and the subsequent recovery events in the host liver are still limited. In this study, a murine model of schistosomiasis japonica was used to characterise the multicellular pathways occurring during liver regeneration. Schistosoma japonicum-infected C57BL/6 mice were administered with the drug praziquantel (PZQ), on a daily basis for five consecutive days to eliminate all adult parasites. The pathological changes of PZQ-treated groups after 3, 6 and 7 weeks post PZQ treatment were examined, along with the assessment of cellular infiltration to the liver. PZQ treatment significantly reduced the degree of splenomegaly, granuloma density and the collagen deposition of liver fibrosis. The infiltration of inflammatory cells, including neutrophils, eosinophils and macrophages to the liver were as well significantly decreased. Transcriptomic analysis revealed the significant up-regulation of fatty acid metabolism genes and the identification of peroxisome proliferator-activated receptor alpha (PPAR-α) as the upstream regulator during the process of liver recovery. Aryl hydrocarbon receptor (AhR) signalling pathway that is involved primarily in the regulation of hepatic enzymes responsible for xenobiotic metabolism was as well differentially up-regulated. These findings indicate that schistosome egg-induced fibrogenesis process is reversible, and provide a better understanding of the regression mechanisms associated with hepatic schistosomiasis. These results hold important implications for the future alleviation of this and other fibrotic diseases of clinical significance. C57BL/6 murine model infected with S. japonicum were treated orally with Praziquantel (PZQ) after 7 weeks post infection to examine the hepatic regression process following drug treatment. These PZQ-treated, non PZQ-treated and uninfected mice were then euthanised at 10, 13, and 14 weeks p.i. Livers were collected from each mice, and subjected to total RNA isolation and gene expression analysis. Microarray analysis of this study was performed using samples derived from 3 individual mice per group/time-point.
