Effect of 5-min RF with HFD at ZT 5 on NE secretion and metabolism in the hippocampus at ZT 1 and 13 with and without FST (Experiment 6). (A) Sampling schedules. Mice were sacrificed at ZT 1 or 13 without FST, after mice were kept on each feeding condition for 4 weeks (no FST). (B–D) MHPG (B), NE (C), and the metabolic rate (MHPG/NE; D) levels in the hippocampus at ZT 1 and 13. (E) Sampling schedules. Mice were sacrificed at ZT 1 or 13 just after the FST, after mice were kept on each feeding condition for 4 weeks (after FST). (F-H) MHPG (F), NE (G), and the metabolic rate (H) levels in the hippocampus at ZT 1 and 13 after the FST. (I-K) Stress reactivity of MHPG (I), NE (J), and metabolic rate (K) in the hippocampus. We calculated these levels by dividing each level after FST by the average with no FST. Data are presented as the mean ± SEM (n = 6–8). #p < 0.05, ##p < 0.01, ###p < 0.001 (Mann-Whitney test).
