Abstract: Phenobarbital has long been known to increase cellular levels of CYP1A1 and CYP1A2 possibly through a pathway(s) independent of aryl hydrocarbon receptor. We have investigated the role of constitutive androstane receptor (CAR), a xenobiotic-responsive nuclear receptor, in the transactivation of human CYP1A1 and CYP1A2. These genes are located in a head-to-head orientation, sharing a 5'-flanking region. Reporter assays were thus performed with dual-reporter constructs, containing the whole or partially deleted …
