behavior/neurological
• decreased mobility in the tail suspension test
• in an elevated plus maze, mice spend less time in open arms and more time in closed arms, freezing incidence and duration of freezing and fewer head dips than wild-type mice
• in an open field

homeostasis/metabolism
• increased in the urine of male, but not female, mice

cardiovascular system
N
• mice exhibit normal blood pressure and baroreflex sensitivity
• over both a 24 hr period and at night

nervous system
N
• mice exhibit normal baroreflex sensitivity
