did not reach statistical significancep = 0.1266
Tail suspension test Pdyn KO mice on the balb/c background spent a prolonged time immobile (43.2±28.9 sec (n = 10) vs 74.5±40.8 sec (n = 15); p = 0.0474; WT and Pdyn KO respecitively), while the delay to to onset of the first immobile phase did not reach statistical significance (127±60,4 sec (n = 10) vs 88±60.7 sec (n = 15); p = 0.1266; WT and Pdyn KO respecitively).
