Cyp3a7
WebCYP3A7 is the predominant CYP3A enzyme in fetal and neonatal liver. CYP3A7 expression declines after birth in parallel with a dramatic increase in CYP3A4 and CYP3A5, which become the most abundant CYPs in adult liver and intestine (2) . WebAug 7, 2014 · Human adult hepatocytes expressing CYP3A4, a major cytochrome P450 enzyme, are required for cell-based assays to evaluate the potential risk of drug-drug interactions caused by transcriptional induction of P450 enzymes in early-phase drug discovery and development.
