FIGURE 7.

Blood glucose, insulin, and catecholamines for male mice at 24 weeks. Mice were fasted for 4 hours prior to serum collection. A, Tail vein whole blood was used to monitor glucose using an Alpha TRAK 2 monitoring kit. B‐E, Serum was analyzed to measure insulin and the indicated hormones. Statistical analysis was by Student's t tests, with only P values below .05 indicated and measurements below the detection limit were substituted with the lowest detectable level of each assay divided by 2^1/2, as described (Ogden, 2010). Bars indicate mean ± SE. Data represent seven male mice per group
