WebJan 31, 2024 · Cytochrome P450 (CYP) 3A subfamily undergoes developmental changes in expression, such as a transition from CYP3A7 to CYP3A4 shortly after birth, which provides a potential way to distinguish medication effects on fetuses/neonates and adults. 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) .
