3 One of the major unsolved problems in xenobiotic metabolism is the molecular mechanism whereby phenobarbital induces hepatic enzymes, particularly CYP2B1 and CYP2B2 in rat liver. Phenobarbital cytochrome P450, family 2, subfamily b, polypeptide 2 Rattus norvegicus
4 By using primary rat hepatocytes for transfection analyses, we previously identified in the CYP2B2 5"-flank a 163-base pair Sau3AI fragment that confers phenobarbital inducibility on a cat reporter gene and that has the properties of a transcriptional enhancer. Phenobarbital cytochrome P450, family 2, subfamily b, polypeptide 2 Rattus norvegicus
5 Taken together, the results indicate that phenobarbital induction of CYP2B2 requires interactions among multiple regulatory proteins and cis-acting elements constituting a phenobarbital response unit. Phenobarbital cytochrome P450, family 2, subfamily b, polypeptide 2 Rattus norvegicus
