Potential biomarkers and metabolomics of acetaminophen-induced liver injury during alcohol consumption: A preclinical investigation on C57/BL6 mice

The toxic effects of alcohol consumption on population health are significant worldwide and the synergistic toxic effects of concurrent intake of Acetaminophen and alcohol is of clinical concern. The understanding of molecular mechanisms beneath such synergism and acute toxicity may be enhanced through assessing underlying metabolomics changes. The molecular toxic activities of the model hereby, is assessed though metabolomics profile with a view to identifying metabolomics targets which could aid in the management of drug-alcohol interactions. In vivo exposure of C57/BL6 mice to APAP (70 mg/kg), single dose of ethanol (6 g/kg of 40%) and APAP after alcohol consumption was employed. Plasma samples were prepared and subjected to biphasic extraction for complete LC-MS profiling, and tandem mass MS2 analysis. Among the detected ions, 174 ions had significant (VIP scores >1 and FDR
