mortality/aging
|
• only a few mice survive beyond 1 month of age
|
|
• most die within the first month of life
|
adipose tissue
N |
• despite loss of white fat, brown fat is relatively unaffected
|
|
• by 3 weeks of age all white adipose deposits are absent
|
behavior/neurological
N |
• no defect in eating behavior is detected, despite the absence of white fat
|
digestive/alimentary system
N |
• no defect in fat absorption is detected, despite the absence of white fat
|
growth/size/body
|
• severely runted by 3 weeks of age
|
homeostasis/metabolism
cellular
|
• by 3 weeks of age the proliferative index in most tissues is reduced
|
reproductive system
|
• lack a well-developed corpus luteum
|
|
• the few females that reach reproductive age are infertile
|
|
• the few males that reach reproductive age are infertile
|
skeleton
|
• at P21, long bone growth plates are severely dysplastic with many cells having mega-nuclei
|
endocrine/exocrine glands
|
• the outer cortex lacks a functional zona fasciculata
|
|
• lack a well-developed corpus luteum
|
nervous system
|
• by 21 days of age there is a relative increase in the brain weight to body weight ratio
|
respiratory system
|
• decrease in the branching of the epithelium

embryo
N |
• placentas appear normal with well-organized labyrinthine architecture and vasculature, and are functional as fetuses lack signs of acute stress response or ectopic cell apoptosis
• live embryos/fetuses are recovered at all stages analyzed, including at birth
