Cyp induction zebrafish
WebMetabolic activation is the primary cause of chemical toxicity including hepatotoxicity. Cytochrome P450 2E (CYP2E) is involved in this process for many hepatotoxicants, including acetaminophen (APAP), one of the most common analgesics and antipyretics. Although the zebrafish is now used as a model for toxicology and toxicity tests, the … WebCYP Induction: from Drug Discovery to IND Posted 15th December 2024 by Cyprotex Cytochrome P450 (CYP) induction plays an important role in the pharmacokinetics of a drug and can potentially affect drug efficacy through reducing plasma half-life, or drug toxicity if elevated levels of toxic metabolites are formed.

WebIn adult zebrafish, the highest basal expression of CYP1A mRNA can be found in liver and gut tissue. Compared to other CYP1s, CYP1A mRNA levels are the highest in organs of the abdominal cavity and the heart (Jﾃｶnssonet al., 2007b), with expression mainly in the car- diovascular system during the embryonic development (Otteet al., 2010).
