Effects of Exercise and a High-Fat Diet on the Body Weight Growth of Orexin Neuron-Ablated Mice
(A) Male wild-type mice. Chow without a wheel (n = 12), high-fat diet (HFD) without a wheel (n = 11), chow with a wheel (n = 7), HFD with a wheel (n = 12).
(B) Male orexin-ataxin3 mice. Chow without a wheel (n = 10), HFD without a wheel (n = 9), chow with a wheel (n = 8), HFD with a wheel (n = 7).
(C) Female wild-type mice. Chow without a wheel (n = 20), HFD without a wheel (n = 10), chow with a wheel (n = 9), HFD with a wheel (n = 10).
(D) Female orexin-ataxin3 mice. Chow without a wheel (n = 7), HFD without a wheel (n = 8), chow with a wheel (n = 8), HFD with a wheel (n = 6).
For (A)–(D) body weight was measured weekly from the ages of 4 to 15 weeks. Mice were fed normal chow or a high-fat diet and housed in a cage equipped with or without a running wheel. Two-way ANOVA followed by a comparison of the main effect after Bonferroni adjustment. *p < 0.05, **p < 0.01, ***p < 0.001. Data are presented as mean ± SEM.
