. Male db/db mice (n=00) were divided into five groups: the vehicle-treated group (VG) (n=0); the insulin glargine-treated group (GG) (dose, 000 μg/kg) (n=0), the low-dose liraglutide-treated group (LLG) (dose, 00 μg/kg) (n=0), the mid-dose liraglutide-treated group (MLG) (000 μg/kg) (n=0), and the high-dose liraglutide-treated group (HLG) (000 μg/kg) (n=0). The data represent the mean ±SEM. \* P\<0.00, \*\* P\<0.00, \*\*\* P\<0.000 GG, HLG, MLG or LLG *vs.* VG. ^\#
