The Peroxisome Proliferator Response Element of the Gene Encoding the Peroxisomal β-Oxidation Enzyme Enoyl-CoA Hydratase/3-Hydroxyacyl-CoA Dehydrogenase Is a Target for Constitutive Androstane Receptor β/9-cis-Retinoic Acid Receptor-mediated Transactivation*

The genes encoding the first two enzymes of the peroxisomal beta-oxidation pathway, acyl-CoA oxidase (AOx) and enoyl-CoA hydratase/3-hydroxyacyl-CoA dehydrogenase (HD), contain upstream cis-acting regulatory regions termed peroxisome proliferator response elements (PPRE). Transcription of these genes is mediated through the binding of peroxisome proliferator-activated receptor alpha (PPARalpha), which binds to a PPRE as a heterodimer with the …
