WebHere, to study the xenobiotic-induced fluctuations in CYP during inflammation, we examined the effect of lipopolysaccharide (LPS) treatment on the level of mRNAs encoding hepatic CYPs induced by xenobiotic-activated nuclear receptors, in mice. Both the mRNA induction of Cyp genes and the metabolic activities of CYP proteins were examined. WebCytochrome P450s are oxidative metabolic enzymes that play critical roles in the biotransformation of endogenous compounds and xenobiotics. The expression and activity of P450 enzymes varies considerably throughout human development; the deficit in our understanding of these dynamics limits our abil …
