Body weight change, depressive-like behaviors, and monoamine neurotransmitter levels in different groups. A The schematic representation of experiment schedule. B Body weight change (%) in week 6. C Sucrose preference (%) in the SPT. D Immobility time in the FST. E The number of crossings in the OFT. F The number of rearings in the OFT. G The feeding latency in the NSFT. H The relative levels of monoamine neurotransmitter (5-HT, NE, and DA) in serum. Data are presented as the mean ± SEM (n = 8). *p_adj < 0.05, **p_adj < 0.01, ***p_adj < 0.001 versus the control group (Con); ^#p_adj < 0.05, ^##p_adj < 0.01, ^###p_adj < 0.001 versus the CUMS group
