摘要: with [ 3 H]-2-deoxyglucose without or insulin (60 U/ml) to measure glucose uptake. Insulin-stimulated uptake for paired muscles was calculated by subtracting from insulin. Muscles other mice were assessed glycogen and AMPK Thr 172 phosphorylation. Exercised vs. sedentary had decreased in epitrochlearis (48%, P0.001), soleus (51%, P 0.001), EDL (41%, 0.01) increased phosphorylation (P 0.05) (1.7-fold), (2.0-fold), (1.4-fold). Insulin-independent 30 min postexercise the (1.2-fold, (1.4-fold, 0.05), (1.3-fold, 0.01). Insulinstimulated 85 after exercise (sedentary: 0.266 0.045 molg 1 15 ; exercised: 0.414 0.051) 0.102 0.049; 0.347 0.098) but not EDL. Akt Ser 473 308 insulin-stimulated did differ exercised sedentary. These results demonstrate enhanced submaximal insulinstimulated of suggest that it will be feasible probe mechanism sensitivity using genetically modified mice.
