Short-term HFD feeding alters energy balance in Park2 KO mice. After 1 wk of HFD, body weight-matched mice were housed in metabolic cage units and maintained on HFD. A: body weight and composition determined by ¹H magnetic resonance spectroscopy. B: energy expenditure (EE) determined by indirect calorimetry. C: activity or X-ambulatory counts. D: feeding activity. E: respiratory exchange ratio (RER). Data are means ± SE; n = 7 per group. *P < 0.05 and **P < 0.01 vs. WT. Data were analyzed by Student's t-test.
