Abstract:


Background and Objective: A Tibetan traditional herb named Swertia mussotii Franch., also called “Zangyinchen” by the local people of the Qinghai-Tibet area, has been used to protect the liver from injury for many years. However, the curative effect and molecular mechanism of the herb have not been demonstrated clearly.

Materials and Methods: In our study, serum alanine aminotransferase, aspartate aminotransferase, and total bilirubin levels were examined after S. mussotii Franch. treatment of the acute liver injury on the carbon tetrachloride-induced rat model. Then, proteome analysis was conducted to explore the potential mechanism of SMT for hepatoprotective effects after iTRAQLC-MS/MS analysis (isobaric tag for relative and absolute quantification-liquid chromatography-mass spectrometer with tandem mass spectrometry).

Results: Serum results showed that alanine aminotransferase, aspartate aminotransferase, and total bilirubin levels of rats with acute liver injury were all improved with SMT treatment. Moreover, proteome analysis suggested that, with S. mussotii Franch. treatment, the levels of lipid catabolic process and lipid homeostasis were all enhanced. Furthermore, the results of protein-protein interaction (PPI) analysis illustrated that the proteins assembled in PPI networks were found to be significantly enriched in response to lipid, negative regulation of lipase activity, and in response to lipopolysaccharides. Furthermore, the down-regulated MRP14 and MRP8 proteins were found to be involved in the lipid metabolism, which may indicate the mechanism of SMT for the protection of the liver from ALI induced by carbon tetrachloride.

Conclusion: SMT herb could play a role in hepatoprotection and alleviating the acute liver injury by impacting the lipid metabolism associated with the biological process.
