Fig. 2. The effects of running exercise and fluoxetine on the depression-like behaviors of UCS-exposed mice.
a Line graph illustrating the BWs of the mice in the CTRL group (n = 14) and the UCS group (n = 42) during the first 4 weeks. b Line graph illustrating the sucrose preferences of the mice in the CTRL group (n = 14) and the UCS group (n = 42) during the first 4 weeks. c FST immobility time (in seconds) of the mice in the CTRL group (n = 14) and the UCS group (n = 42) at the end of the 4th week. d Line graph illustrating the BWs of the mice in the CTRL group (n = 14), UCS group, UCS + RN group, and UCS + FLX group during the last 4 weeks (n = 14 for each group). **indicates P < 0.01, UCS group vs. CTRL group. ## indicates P < 0.01, UCS + RN group vs. CTRL group. ΔΔ indicates P < 0.01, UCS + FLX group vs. CTRL group. e Line graph illustrating the sucrose preferences of the mice in the CTRL group, UCS group, UCS + RN group, and UCS + FLX group during the last 4 weeks (n = 14 for each group). **indicates P < 0.01, UCS group vs. CTRL group. ## indicates P < 0.01, UCS + RN group vs. CTRL group. ΔΔ indicates P < 0.01, UCS + FLX group vs. CTRL group. f FST immobility time (in seconds) of the mice in the CTRL group, UCS group, UCS + RN group, and UCS + FLX group at the end of 8 weeks (n = 14 for each group). g FST immobility time (in seconds) of the mice in the CTRL group, UCS group, UCS + RN group, and UCS + FLX group at the end of the 8th week (n = 14 for each group). All data are shown as the means ± SDs, * P < 0.05, and ** P < 0.01.
