|
behavior/neurological
|
• circadian period 1 hour longer for motor activity than wild-type in constant darkness
(J:51110)
• capable of entrainment to light, but with more variance than wild-type controls
(J:51110)
|
|
• significant reduction in the relative power of the circadian range is seen when placed in constant darkness
|
skeleton
|
• in the long bones and vertebrae
|
vision/eye
N |
• pupilary reflex is the same as in wild-type controls
|
vision/eye
|
• substantial loss of constriction in response to light
• response is similar to that in mice homozygous for Pde6brd1 alone
|
behavior/neurological
|
• substantial loss of constriction in response to light
• response is similar to that in mice homozygous for Pde6brd1 alone

Retinal degeneration in Pde6brd1/Pde6brd1, and Pde6brd1/Pde6brd1 Cry1tm1Asn/Cry1tm1Asn Cry2tm1Asn/Cry2tm1Asn mouse retinas
behavior/neurological
|
• almost no pupillary reflex in blue light (470-nm)
• some pupillary movement in very bright light, but sluggish
• sensitivity to blue light is about 5% that of mice homozygous for Pde6brd1 only
|
|
• arrhythmic circadian rhythms for locomotor activity in constant darkness
|
|
• arrhythmic circadian rhythms for locomotor activity in light/dark cycles
• mutants accumulate nearly 40% of their total daily activity during the first 10 hours of the light portion of light-dark 12:12 compared with only 10% of activity during this same period seen with controls, indicating a residual photoresponsiveness in mutants
|
vision/eye
|
• almost no pupillary reflex in blue light (470-nm)
• some pupillary movement in very bright light, but sluggish
• sensitivity to blue light is about 5% that of mice homozygous for Pde6brd1 only
|
|
• nearly complete absence of the outer nuclear layer
|
|
• the entire outer retina is destroyed, however the inner retina remains intact
|
nervous system
behavior/neurological
|
• immediate loss of rhythmicity when switched to constant darkness
|
adipose tissue
|
• dramatic decrease in subcutaneous fat mass
|
|
• dramatic decrease in visceral fat mass
|
|
• total body electrical conductivity is significantly decreased indicating a decrease in total body fat mass
|
|
• lipid droplet size is decreased
|
growth/size/body
|
• seen from 5 weeks of age on
|
homeostasis/metabolism
cardiovascular system
|
• heart rate remains elevated during the light phase of the day-night cycle
• absence of diurnal rhythms in heart rate under 12 h dark light conditions
|
