♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

behavior/neurological

abnormal righting response ( J:71826 )

• 50 mg/kg and 60 mg/kg of sodium pentobarbital induces a greater loss of righting reflex (LORR) than in wild-type mice (135% and143%, respectively by dose)

• however, righting response is no different from that of wild-type mice after treatment with ketamin

• NPY-induced sensitization to LORR induced by pentobarbital or ketamine is increased compared to in wild-type mice

• NPY-induced sensitization to LORR induced by pentobarbital greater when NPY is injected into the posterior hypothalamus versus the lateral hypothalamus

abnormal sleep duration ( J:71826 )

• mice sleep longer than wild-type mice following treatment with pentobarbital

adipose tissue

increased total fat pad weight ( J:57961 )

behavior/neurological

abnormal food intake ( J:57961 )

• mutants show an attenuated response to leptin, exhibiting only a 15.2% reduction in food intake compared to 30.5% decrease in wild-type mice, 12 hours after leptin administration, however no differences in food intake are observed after 45 hours

polyphagia ( J:57961 )

• mean 12% increase in 24-hour food consumption

decreased locomotor activity ( J:57961 )

• reduction in activity during both dark and light phases

cardiovascular system

abnormal circadian regulation of heart rate ( J:57961 )

• increase shows statistical significance at night

growth/size/body

increased body weight ( J:57961 )

• males and females fed a normal-fat diet are mildly overweight

• a high-fat diet leads to a more substantial increase in body weight, especially in females

homeostasis/metabolism

decreased energy expenditure ( J:57961 )

• reduction in energy consumption as indicated by reduced activity during both light and dark phases

alcohol aversion ( J:102430 )

behavior/neurological

abnormal righting response ( J:71826 )

• authors state that mice display a similar sensitivity to loss of righting response induced by pentobarbital as Npy1r^tm1Pern homozygous mice

• mice display a decrease in loss of righting response to ketamin-sedation compared to wild-type mice
