摘要: The prediction of metabolism-dependent toxicity is a cutting-edge topic in toxicology (Bolt and Hengstler, 2008). shape dose-response curves toxic profiles are strongly dependent on activating or detoxifying metabolism. Most xenobiotic metabolizing enzymes include large numbers isoenzymes with distinct substrate specificities. This diversity started to evolve 200 400 million years ago when reptiles amphibians moved from sea land began eat plants. resulting co-evolution led the establishment phytotoxins which gave plants protection against herbivores, herbivores responded new enzymes. A highlight our partner journal initiation series review articles discussing nomenclature isoenzyme families, genetic organization, polymorphisms, specificities, clinical relevance role carcinogenesis (Mates et al., 2008; Florl Schulz, Strassburg Beyersmann Hartwig, Pelkonen Verstraeten Adam Laufs, To give readers an overview we summarize key messages drug metabolism (Table 1A) enzyme induction 1B).
