Twelve-week-old male wild type mice were infected with an adenovirus harboring GFP or FERM for 3 days, fasted for 4 hours and intraperitoneally injected with glucagon. (G) Blood glucose levels (mg/dL) were measured 0, 15, 30, 60 and 120 minutes after glucagon stimulation (0.2 mg/kg body weight, n = 10 mice/ group).
