WebThe induction of cytochromes P450 may result in interactions between xenobiotics and in the interference of xenobiotic metabolism and endogenous signalling pathways. Publication types Review MeSH terms Amino Acid Motifs Animals Bacillus / enzymology Base Sequence Binding Sites Cytochrome P-450 Enzyme System / biosynthesis* WebInduction of cytochromes P450 (P450s) by drugs can lead to drug-drug interactions. Primary hepatocytes have been reported to retain inducible P450s. To optimize the use of primary hepatocytes for predicting induction of P450 (CYP 3A and 2B) expression in vivo, both culture conditions and expression of induction potentials were investigated.
