Abstract:

Objective Labker quantitative (TMT) proteomics was used to explore the mechanism of chemical inducer (carbon tetrachloride, CCl4) causing acute liver injury in mice. Method Twenty SPF male BALB/C mice were randomly divided into control and induction groups, with 10 mice in each group, induced by intraperitoneal injection for 8 weeks (2 times/week). The degree of liver injury was evaluated by measuring the blood biochemical level and liver histopathological sections. Proteomic analysis was performed by tandem mass spectrometry labeling technology (TMT), including gene Ontology (GO) annotation, KEGG pathways, and protein interaction network analysis of the found differential proteins. Result Compared with the control group, blood indicator of aspartate aminotransferase (AST) was significantly higher (P<0.05); alanine aminotransferase (ALT), y-glutamyl transpeptadase (GGT), total biliary acid (TBA) (P<0.01). Moreover, liver histopathological sections showed significant liver injury in the CCl4 induction group. A total of 5 955 proteins were identified using TMT, with 440 increased intensity and 294 decreased, and differential proteins played important roles in protein expression difference, biomarker application and participation in classical signaling pathways (JAK-STAT, PI3K-Akt, Rap 1, GnRH, AGE-RAGE). There was a significant enrichment of differential proteins in classical signaling pathways and a relatively high enrichment. Conclusion CCl4 as an ideal chemical inducer for liver injury evaluation, it is involved in several key processes such as immunity, cell division, apoptosis and autophagy, inflammation and tumor formation. It reduces the pathological mechanism of liver injury in multiple directions and targets and provides a solid theoretical basis and perspective for the research and development of liver protection drugs.
