FGFR2 and Anxiety: On the elevated plus maze (Fig. 3G, ANOVA interaction: F (2, 36) = 5.260, p = 0.0099) these FGFR2 iKO mice demonstrated trend less time spent in the closed arms (p = 0.05), more time in the open arms (p = 0.08), and higher ratio of time in the open to closed zones (Fig. 3H; p = 0.07), indicative of less anxiety-like behavior, but no differences in overall activity level (Fig. 3I) or in the ratio of entries in the zones (data not shown; p = 0.23).
