|
|
|
• mice fed a high-fat diet for 12 weeks show that visceral fat depots are greatly decreased in mutants
|
|
|
• smaller body size that is apparent in newborns and remains throughout development
|
|
|
• at 12 weeks of age, mice weight about 20% less than wild-type mice
|
|
|
• the nose-anus length is reduced by about 5% at 12 weeks of age
|
|
|
• mice fed a high-fat diet for 12 weeks become less obese than wild-type mice, with weight of liver, white adipose tissue and brown adipose tissue less than that of wild-type mice on the same diet
|
|
|
• mice fed a high-fat diet for 12 weeks become less obese than wild-type mice, with weight of liver, white adipose tissue and brown adipose tissue less than that of wild-type mice on the same diet
|
|
|
• mice fed a high-fat diet for 12 weeks exhibit lower blood glucose levels and remain lower in both glucose tolerance and insulin tolerance tests
|
|
|
• decrease in blood glucose under fasting conditions
• however, no differences in serum insulin levels
|
|
|
• decrease in serum triglyceride levels under feeding and fasting conditions
|
|
|
• whole-body oxygen consumption is higher during dark and light periods, with 24 hour oxygen consumption rates 20% higher than in wild-type mice
• however, rectal temperature is normal
|
|
|
• glucose tolerance test shows that blood glucose levels remain lower than in wild-type mice after glucose administration
• mice fed a high-fat diet for 12 weeks remain lower in the glucose tolerance test
• however, the insulin response was similar to wild-type mice
|
|
|
• insulin tolerance test shows a greater decrease in blood glucose levels in mutants than in wild-type mice in response to insulin
• mice are insulin sensitive even on a high-fat diet
|
|
|
• mice fed a high-fat diet for 12 weeks show that subcutaneous fat depots are greatly decreased in mutants
|
|
|
|
|

|
|
• RANKL-induced osteoclastogenesis in bone marrow cells is enhanced, indicating an increase in differentiation into osteoclasts
|
|
|

|
|
|
• increase in the number of osteoclasts per bone surface and in the levels of osteoclast surface per bone surface
|
|
|
• RANKL-induced osteoclastogenesis in bone marrow cells is enhanced, indicating an increase in differentiation into osteoclasts
|
|

|
|
• decrease in bone mineral density at 4 months of age
|
|
|
• aged mice (2 years) show a decrease in cortical bone thickness
|
|
|
• trabecular bone exhibits a sparse osteoporotic pattern at 4 months of age
• increase in the levels of trabecular separation and trabecular spacing at 4 months of age, which increases with age
|
|
|
• decrease in trabecular number at 4 months of age
• aging induced osteoporosis results in a 3-fold reduction in the baseline levels of trabecular number compared to 4 month old mutants
|
|
|
• decrease in trabecular bone mass at 4 months of age
|
|
|
• trabecular thickness is slightly reduced but is not significant, however aged mice show reduced thickness of trabecular bone
|
|
|
• decrease in levels of the bone volume per tissue volume at 4 months of age
• osteoporosis is exacerbated with age, with bone volume further reduced by about 50% at 2 years of age, and a further increase in trabecular separation and trabecular spacing and bone resorption
|
|
