Significance
Fructus Psoraleae, a traditional Chinese medicine, is widely used in Asia for the treatment of osteoporosis and vitiligo. Recently, clinical and experimental reports reveal that FP can induce liver injury. However the mechanism of injury induced by FP is still unclear. In this study, we detected 352 significantly up-regulated proteins and 223 significantly down-regulated proteins in liver tissues by TMT-based quantitative proteomics. And 14 important metabolites were identified by metabolomics analysis. Through integrative analysis of the key metabolites and proteins, several metabolism pathways were selected, which implicated in bile acid metabolism, oxidative stress, energy metabolism, immune system. This is the first integrative study of proteomics and metabolomics for FP exposure, the finding clarified the potential mechanism of hepatotoxicity caused by FP and will promote rational use of FP in clinical application.
