mortality/aging
• many pups die perinatally
• fewer than the expected Mendelian ratio of pups is seen at weaning (only 17 out of 277 total pups)

growth/size/body
• mice fed a high-fat diet are slightly leaner than wild-type mice, although both show hepatic steatosis
• pups are smaller at 2 days of age
• surviving mice have reduced body mass at 1 month of age, however by 4 months of age, mice weight the same as wild-type mice

liver/biliary system
• 30% increase in apoptosis in livers at 1 month of age
• reduction in the number of binuclear hepatocytes and tetraploidy suggest impaired hepatic differentiation and maturation
• livers show continued presence of hematopoietic cells at 1 month of age unlike in wild-type mice which show only residual CD45-positive hematopoietic cells, however, numbers of circulating blood cells are normal indicating a defect in hepatocyte maturation rather than increase in extramedullary hematopoiesis
• livers of surviving mice exhibit a roughened surface and multiple small nodules
• architecture of the liver is disturbed with large irregular hepatocytes, compressed sinusoidal spaces and bile canaliculi and clusters of small hematopoietic cells
• decrease in lipid droplets in the liver of 1 month old mice
• compressed sinusoidal spaces
• 60% decrease in stored glycogen in the liver
• decrease in cholesterol in the liver at 1 month of age but not at 4 months of age
• mice fed a high-fat diet do not show an increase in hepatic triglyceride levels as is seen in wild-type mice
• compressed bile canaliculi
• hepatocytes are larger with irregularly sized nuclei and dense mitotic figures
• reduction in the number of binuclear hepatocytes and tetraploidy suggesting impaired hepatic differentiation and maturation
• surviving mice have smaller livers at 1 month of age
• surviving mice have pale livers at 1 month of age

homeostasis/metabolism
• decrease in fatty acid oxidation in the liver
• mice fed a high-fat diet are slightly leaner than wild-type mice, although both show hepatic steatosis
• mice exhibit fasting-induced hypoglycemia at 1 month of age however, fasting insulin levels are normal
• by 4 months of age, fasting blood glucose levels are normal
• serum cholesterol is lower at 1 month of age on a normal diet and at 4 months of age on the high-fat diet
• serum triglyceride levels are lower on a normal diet and are unchanged on a high-fat diet
• total serum protein is decreased due to a 30% decrease in serum albumin
• however, blood urea nitrogen, calcium, and creatinine are normal
• glucose tolerance tests at 4 months of age in mice fed a low-fat diet for 12 weeks show decreased glucose at 15 min but normal values at subsequent times
• 60% decrease in stored glycogen in the liver
• insulin tolerance tests at 4 months of age in mice fed a low-fat diet for 12 weeks show increased insulin sensitivity and an inability to correct insulin-induced hypoglycemia
• mice fed a high-fat diet for 12 weeks show increased insulin sensitivity compared to wild-type mice, with a greater drop in blood glucose during the insulin tolerance test
• decrease in cholesterol in the liver at 1 month of age but not at 4 months of age
• mice fed a high-fat diet do not show an increase in hepatic triglyceride levels as is seen in wild-type mice

adipose tissue

cardiovascular system
• compressed sinusoidal spaces

cellular
• the rough endoplasmic reticulum (ER) is dilated in the liver, indicating ER stress
• 30% increase in apoptosis in livers at 1 month of age
• decrease in fatty acid oxidation in the liver

endocrine/exocrine glands
• impaired thymic development

hematopoietic system
• impaired thymic development

immune system
• impaired thymic development

renal/urinary system
• impaired kidney development
