Analysis Tools
mortality/aging
|
• further and substantial loss is also observed during weaning
• however, mutants can survive to adulthood if mothers are gestated on fucose-supplemented water and if mutants are given chow and water supplemented with fucose
|
|
• progeny surviving up to weaning, die 2 to 3 weeks after weaning
• viablity is increased with fucose-supplemented diet
|
|
• further loss is seen at E16.5 and immediately prior to birth, the number of embryos is about 28% of the predicted number
• dietary fucose given to the mother is not able to rescue the survival of mutants to term
|
|
• some lethality is observed at E12.5
|
growth/size/body
|
• those mutants that survive birth and weaning are runted
• small size is rescued by 6 weeks of age when mutants are reared on a fucose-supplemented diet
|
digestive/alimentary system
|
• thickened mucosa
|
|
• crypt destruction and distortion in the colon
|
|
• mutants exhibit characteristics of inflammatory bowel disease; thickened mucosa, crypt destruction and distortion, crypt abscesses, regenerative crypt and surface epithelium, and a mixed inflammatory cell infiltrate within the lamina propria
• colon histology is reversed by fucose supplementation
|
|
• mutants reared on a standard chow constantly suffer from diarrhea that can be terminated with a fucose-supplemented diet
• diarrhea does not occur in mutants reared from birth on a fucose-containing diet
|
|
• mixed inflammatory cell infiltrate within the lamina propria of the colon
|
hematopoietic system
|
• myeloid-erythroid (M/E) ratio in the marrows of mutants on a standard diet is increased by more than 2-fold
• the M/E ratio normalizes after fucose supplementation
|
|
• 2-fold increase in colony-forming unit-granulocyte macrophage (CFU-GM)
• CFU-GM numbers can be normalized with fucose supplementation
|
|
• mice reared on a standard diet exhibit blood leukocytosis that is reduced with fucose administration
|
|
• 25-fold increase in neutrophils that is reduced by about half within 8 hours of oral fucose administration
|
immune system
|
• mixed inflammatory cell infiltrate within the lamina propria of the colon
|
|
• mice reared on a standard diet exhibit blood leukocytosis that is reduced with fucose administration
|
|
• 25-fold increase in neutrophils that is reduced by about half within 8 hours of oral fucose administration
|
reproductive system
infertility
(
J:82239
)
|
• males and females are infertile on a standard diet
• fertiliy is rescued on a fucose-supplemented diet
|
behavior/neurological
endocrine/exocrine glands
|
• crypt destruction and distortion in the colon
|
homeostasis/metabolism
|
• 48% increase in serum creatinine
|
dehydration
(
J:82239
)
|
• diarrhea is accompanied by evidence of dehydration such as tenting of the skin and an increase in serum creatinine
