Fig. 3

Changes in core temperature (ΔTc) and oxygen consumption (ΔVO2) of 6 months old male Wistar rats of different intervention groups following an intracerebroventricular (ICV) injection of urocortin 2 (UCN2). Dark symbols indicate UCN2-treated, empty symbols indicate results of age-matched controls. (Panels a, b, and c show the results obtained in ad libitum fed sedentary NF6, ad libitum fed treadmill trained TR6 and caloric restricted sedentary CR6 rats, respectively.) Control animals received pyrogen-free saline (PFS). Asterisks indicate significant differences between the UCN2-treated and control animals shown by repeated-measures ANOVA. Number of animals per group: TR6 treated n = 7, TR6 control n = 8, NF6 treated n = 8, NF6 control n = 8, CR6 treated n = 10, CR6 control n = 9.
