Abstract

Organisms induce the expression of detoxification enzymes such as cytochrome P450s to deal with xenobiotics encountered in the environment. Research using cell culture systems has identified some of the cis-regulatory elements (CREs) and transcription factors involved in the induction of P450 genes in response to xenobiotic challenges. It was recently found that the CREs required for the basal expression of some P450s are distinct from the CREs involved in their induction. How these CREs mediate induction to xenobiotics in a tissue specific manner is not known. In this paper we show that, in Drosophila melanogaster, the induction response of the P450 gene Cyp6g1 to the xenobiotic Phenobarbit..
