Zebrafish Hepatoxicity Assays
Drug-induced liver injury (DILI) represents a major challenge for the pharmaceutical industry and regulatory authorities, as it is a major problem in both the early and later stages of the drug development process, and the most common cause of post-marketing warnings and withdrawals. Its strategic location and outstanding role in the metabolism of xenobiotics renders the liver particularly susceptible to potential toxic effects of a drug and/or its metabolites. Thus, to set up better tools to screen for DILI of large compound libraries in the early stages of drug development will be allowed to get a better understanding of hepatotoxicity.
Recently, zebrafish embryos and larvae have become a popular model in most aspects of safe high-throughput pharmacology and toxicity screens as well as in disease models, especially for investigation of drug effects on liver structure and function. Concerning zebrafish liver, it has been vascularized by 3 days post-fertilization, functioning and excreting various chemicals. Compared to mammals, zebrafish larvae can catalyze similar phase 1 and phase 2 reactions and metabolic pathways for some drugs. Zebrafish have a wide range of cytochrome P450 enzymes that allow metabolic reactions including hydroxylation, oxidation, conjugation, demethylation and de-ethylation. Following exposure to a range of hepatotoxic drugs, the zebrafish liver develops histological patterns of injury compared to those of mammalian liver, and biomarkers for liver injury can be quantified in the zebrafish circulation. In a word, it can serve as a bridge between the in vivo and in vitro models to cover the complete biological complexity, and its ability for high-throughput screening, makes zebrafish a potential model for liver toxicity assay.
