Fig. 1: dLAN group mice exhibited postpartum depression-like behaviors.

A Schematic timeline of the experimental design. B Sucrose preference percentage between control and dLAN groups mice on PPD10-12 (t = 2.614, df = 14, p = 0.0204). C Immobile time (s) during FST between control and dLAN groups mice on PPD14 (t = 2.852, df = 14, p = 0.0128). D–F OFT. Number of entrances into the center (t = 1.487, df = 14, p = 0.1591) (D), total distance (cm) (t = 1.475, df = 14, p = 0.1623) (E), time spent in the center (s) (t = 0.5428, df = 14, p = 0.5958) (F) of the OFT between control and dLAN groups mice on PPD8. N = 8 mice per group. Two-tailed unpaired Student’s t-test was used in all of the above experiments. Data are shown as mean ± SEM (*p < 0.05).
