Abstract excerpt
Cyp1B1 is expressed constitutively in many extrahepatic cells and is induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). An enhancer region (AhER-810 to -1075 of the mouse Cyp1B1 promoter), which mediates aryl hydrocarbon receptor (AhR) regulation of transcription, contains three consensus XRE sequences (designated XRE1, XRE4, and XRE5) and a central Ebox. XRE5 is essential for both basal and induced activity...
