Smaller Type IIA and IIB muscle fibers in Prkab2tm1.1Grst/Prkab2tm1.1Grst extensor digitorium longus muscles

homeostasis/metabolism
• mice exhibit reduced exercise capacity compared with wild-type mice
• when fed a high-fat diet
• before exercise and after exercise
• mice exhibit increased susceptibility to diet-induced skeletal muscle insulin resistance compared with similarly treated wild-type mice
• mice fed a high-fat diet and stimulated with insulin exhibit an increase in ceramides in the tibialis anterior compared with similarly treated wild-type mice
• aminoimidazole carboxamide ribonucleotide (AICAR)-treated skeletal muscles fail to exhibit an increased in glucose uptake and exhibit a blunted reduction in blood glucose level unlike similarly treated wild-type muscle
• however, AICAR-induced fatty acid oxidation is normal

muscle
• aminoimidazole carboxamide ribonucleotide (AICAR)-treated skeletal muscles fail to exhibit an increased in glucose uptake unlike similarly treated wild-type muscle
• mice fed a high-fat diet exhibit increased glucose uptake compared with similarly treated wild-type mice
• mice exhibit reduced muscle force compared with wild-type mice

growth/size/body

liver/biliary system
• before exercise and after exercise

behavior/neurological
• mice exhibit reduced exercise capacity compared with wild-type mice

cellular
• aminoimidazole carboxamide ribonucleotide (AICAR)-treated skeletal muscles fail to exhibit an increased in glucose uptake unlike similarly treated wild-type muscle
• mice fed a high-fat diet exhibit increased glucose uptake compared with similarly treated wild-type mice
