The environmental contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) may produce its effects by altering gene expression in susceptible cells. In mouse hepatoma cells, TCDD induces the transcription of the cytochrome P1-450 gene, whose product, aryl hydrocarbon hydroxylase, contributes both to the detoxification and to the metabolic activation of carcinogenic polycyclic aromatic hydrocarbons. A DNA fragment containing sequences flanking the 5′ end of the cytochrome P1-450 gene was isolated and analyzed. This DNA fragment contains a cis-acting control element with at least three functional domains: a putative promoter, an inhibitory domain upstream from the promoter that blocks its function, and a TCDD-responsive domain still farther (1265 to 1535 base pairs) upstream of the promoter. These findings, together with results from earlier studies, imply that transcription of the cytochrome P1-450 gene is under both positive and negative control by at least twotrans-acting regulatory factors.
