Cyp induction zebrafish
WebTogether with levels of CYP1A protein and mRNA, the induction of CYP1A catalytic activities may be used both for the assessment of exposure and as early-warning sign for potentially harmful effects of many organic trace pollutants. WebThe CYP genetic features and synteny are well characterized, as is their expression in different organ systems. Moreover, several substrates metabolized by humans also show metabolism in zebrafish, with other CYP isoforms possibly involved.
