Abstract
Liver fibrosis is a common progressive liver disease that can cause liver dysfunction and lead to serious complications. Zi Qi decoction (ZQ) is a traditional formulation that exerts pharmacological effects on the treatment of liver fibrosis. However, precise intervention mechanisms remain unclear. The aim of this study was to synergistically harness proteomics and metabolomics techniques to elucidate the specific target of ZQ and its potential mechanism of action. A carbon tetrachloride (CCl4)-induced liver fibrosis mouse model was established. Subsequently, the protective effect of ZQ on liver fibrosis mice was evaluated according to histopathological examination and biochemical indicators. Quantitative proteomics based on data independent acquisition (DIA) and non-targeted metabolomic analyses revealed the pharmacodynamic mechanism of ZQ. In addition, various cellular and molecular assays were used to detect changes in glycolysis levels in LSECs and mouse liver fibrosis models. The study results showed that ZQ significantly alleviated CCl4-induced liver injury and fibrosis in mice. DIA-based quantitative proteomics and non-targeted metabolomics analyses indicated that ZQ treatment downregulated glycolysis-related proteins such as PKM2, PFKP, and HK2, while regulating glycolysis-related metabolites and pathways. In addition, ZQ down-regulated glycolytic activity in mice with liver fibrosis and in LSECs, and inhibited CXCL1 secretion and neutrophil recruitment. ZQ inhibited LSEC glycolysis and mitigated neutrophil infiltration, thereby playing a therapeutic role in liver fibrosis.
