Identification of key metabolic changes during liver fibrosis progression in rats using a urine and serum metabolomics approach

Abstract: Reversibility of hepatic fibrosis is an intrinsic response to chronic injury, and with on-going damage, fibrosis can progress to its end-stage consequence, cirrhosis. Non-invasive and reliable biomarkers for early detection of liver fibrosis are needed. Based on the CCl4-induced liver fibrosis rat model, urinary and serum metabolic profiling performed by LC-QTOF-MS associated with histological progression were utilized to identify liver fibrosis-specific potential biomarkers for early prediction and to reveal … Show more

“…The processed datasets analysed by principal component analysis (PCA) and orthogonal projections to latent structures discriminant analysis (OPLS-DA) (Trygg et al 2007) using pareto (Par) scaling. VIP (Variable Importance in the Projection) and p(corr) were used (V-Plot) to find statistically changed ions (Chang et al 2017). Ions with VIP > 1.5 and p(corr) > |0.4| were subjected to univariate analysis with False Discovery Rate (FDR) at 5% level for correction of multiple comparisons using Prism v.7 (Graph Pad, San Diego, California, USA).…”

“…The fact that non‐responders showed lower NEFA levels, may reflect a lesser β‐adrenergic stimulation or a metabolic resistance of the β‐adrenoceptor that might explain that NSBB did not reach the desired effect. Glycerophospholipids have been proposed as protective agents in animal models of NASH and declining levels have been described in parallel to liver fibrosis progression . Therefore, it might be hypothesized that lower levels of glycerophospholids observed in HVPG non‐responders might be related to a more fibrogenic phenotype of cirrhosis, which could be less dependent and modifiable by vasoactive systems such as β‐adrenergic stimulation/blockade.…”

The analysis of these metabolites could be a useful non-invasive tool to identify these patients though further validation of the model would be desirable.…”

“…Hepatic fibrosis complicates all chronic liver diseases, whether due to chronic alcoholism, viral B or C infection, or autoimmune, biliary, parasitic or medicinal. It is now accepted that hepatic fibrosis is a dynamic process, causing not only excessive production of matrix components (fibrogenesis) [2], but also a decrease in their degradation (fibrolysis) [3].…”
