Vasopressin and corticotropin-releasing hormone gene responses to novel stress in rats adapted to repeated restraint.

abstract：:The induction of hepatic drug metabolizing enzymes alters not only the metabolism of the xenobiotic substances that induce them but also the metabolism of various endogenous hormones. The xenobiotic receptor constitutive androstane receptor (CAR) (NR1I3) mediates the well-studied induction of CYP2B genes and other dru...
