Figure 7: Prenatal to early postnatal treatment with P021 does not affect body weight and anxiety-like behavior in adult Ts65Dn mice.

(a) The monthly evaluation of body weight of study mice. The Ts65Dn mice weighed less than WT controls. No effect of P021 on body weight was observed. (b–d) Evaluation of anxiety-like behavior by measuring percentage of time spent in open arm (b), number of entries in open arm (c), and number of entries to all arms (d), in a 15 min-trial in elevated plus maze. Ts65Dn mice exhibited hyperactivity in the elevated plus maze. No effect of P021 treatment was observed. Data are presented as mean ± S.E.M. and are based on WT-V-WT (n = 10), WT-P-WT (n = 12), Dn-V-WT (n = 12), Dn-P-WT (n = 11), Dn-V-Dn (n = 13), and Dn-P-Dn (n = 12) mice. *p < 0.05; **p < 0.01***p < 0.001. One-way or two-way ANOVA with Bonferroni’s post-hoc test.
