Many xenobiotics are metabolized in mammalian liver by pathways regulated by constitutive androstane receptor (CAR). Here, we identify early gene targets of mouse liver CAR and investigate their associated, CAR‐induced changes in local chromatin accessibility and transcription factor (TF) recruitment. Genes induced or repressed by the CAR agonist TCPOBOP were identified by RNA‐Seq after 3 or 27 hr. Chromatin sites that dynamically open or close following CAR activation (changes in DNase I hypersensitive sites, ΔDHS) were identified by DNase‐Seq. Genes dysregulated in 3 hr TCPOBOP‐treated mouse liver were enriched in KEGG pathways for retinol and drug metabolism (DAVID analysis; p
