homeostasis/metabolism
• mice exhibit an increase in serum vasopressin levels compared with wild-type mice
• however, treatment with propranolol restores normal levels
• mice exhibit an increase in serum noradrenaline levels compared with wild-type mice
• however, treatment with captopril and propranolol restores normal levels
