behavior/neurological
• during the dark phase, mice consume 30% less food than wild-type mice
|
• during the dark phase, mice consume 30% less food than wild-type mice
|
• during the dark period
|
• mice exhibit direct transitions from wake to REM unlike wild-type mice
• mice exhibit a decrease in the intervals between successive REM sleep periods and shorter latency to REM sleep compared to wild-type mice
• during the light period, mice exhibit shorter REM sleep and wake episodes compared to wild-type mice
|
• mice show severe sleep/wake fragmentation

narcolepsy
(
J:69620
)
• beginning at 6 weeks of age, mice exhibit narcoleptic episodes with abrupt cessation of purposeful motor activity in which a sustained posture change is held until motion is abruptly resumed
• narcoleptic episodes occur during grooming or excited ambulation, last a few seconds to 150 seconds, and are often followed by increased feeding and drinking behaviors
|
homeostasis/metabolism
• 53% increase in the circulating leptin levels to bodyweight ratio in female but not male mice
|
growth/size/body
• at 10 to 12 weeks of age, mice exhibit increased body weight compared to wild-type mice
(J:69620)
|
|
• female but not male mice over 100 days in age have significant increases in body weight compared to littermate controls
(J:128233)
|
nervous system
• by 2 and 12 weeks of age 56% and 99%, respectively, of orexin-containing neurons are lost
