Effects of overcrowding procedures on body weight.

Changes in body weight in (A) Trial 1 and (C) Trial 2. The peaks and troughs in body weight were associated with the overcrowding procedures throughout the SD/OC protocol. Arrowheads represent the intervals in which the mice were overcrowded. Bar graphs show the mean percentage weight gain during the four OC sessions for (B) Trial 1 and (D) Trial 2. Control mice remained single housed during these periods. Data are means ± SEM. n = 10–12. ^∗∗∗P ≤ 0.001 vs. Con; ^†P < 0.05, ^††P < 0.01 vs. Cu(atsm), by one-way ANOVA with Tukey's post hoc tests.
