Blood glucose, insulin and catecholamines for male mice at 24 wk. Mice were fasted for 4 h prior to serum collection. A. Tail vein whole blood was used to monitor glucose using an AlphaTRAK 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 0.05 indicated and measurements below the detection limit were substituted with the lowest detectable level of each assay divided by 21/2, as described (Ogden, 2010). Bars indicate mean ± SE. Data represent 7 male mice per group.
