Analysis Tools
homeostasis/metabolism
| N |
• serum proinsulin levels and proinsulin to insulin ratio are normal
|
|
• in response to hyperinsulinemia, hepatic glucose output is reduced compared to in wild-type mice
• upon hyperinsulinemic clamping, glucose uptake rate is doubled
|
|
• in islet when stimulated with high glucose during the first phase and in total
• following depolarization-evoked exocytosis
• increased islet insulin and proinsulin content
• during an oral glucose tolerance test after overnight fasting
|
|
• in 3 month old mice fed standard chow
• however, levels are normal after a 2 h or overnight fast
|
|
• in 3 month old mice fed standard chow
• however, levels are normal after a 2 h or overnight fast
|
|
• delayed glucose clearance during an oral glucose tolerance test after overnight fasting
• impaired glucose clearance upon re-feeding after overnight fasting
|
|
• suggested by delayed glucose clearance despite increased insulin secretion
• during hyperinsulinemic-euglycemic clamp studies, mice exhibit 1.5-fold lower glucose infusion rate compared with wild-type mice
• severe liver and muscle insulin resistance at 3 months of age
|
endocrine/exocrine glands
|
• beta cells exhibit increased number of insulin granules compared to in wild-type cells
• however, mice exhibit normal size of dense core and islet morphology
|
|
• in islet when stimulated with high glucose during the first phase and in total
• following depolarization-evoked exocytosis
• increased islet insulin and proinsulin content
• during an oral glucose tolerance test after overnight fasting
|
muscle
|
• impaired glucose uptake in the soleus and extensor digitorum longus
|
adipose tissue
| N |
• brown and white adipose tissue glucose uptake was normal
|
cellular
|
• impaired glucose uptake in the soleus and extensor digitorum longus
