The preclinical safety assessment of hepatotoxicity drugs has a low sensitivity and low specificity. Related tests often generate false negative results and unexpected toxicity,which is one of the major reasons for the cessation of development and withdrawal from the market. Proteomics enjoys advantages of rapidness,high sensitivity and high throughout,and therefore can be used in the search for new biomarkers of hepatotoxicity in preclinical studies,leading to the development of safer drugs and a more efficient drug discovery process. In this review,the current preclinical biomark?ers of liver toxicity and development of proteomic technologies in the discovery and validation of bio?markers of drug-induced liver injury are described,in general the application of proteomics to Chinese medicine-induced liver toxicity in particular. Compared with traditional methods,proteomic technologies show promising results for the discovery of novel hepatotoxic markers. Proteomics,in conjugation with other omics techniques,will play a major role in the early stage of hepatotoxicity screening and will prove to be a good bridge in clinics in the future.
