Involvement of DARPP-32 in fluoxetine-mediated immobility in the tail-suspension test for antidepressant efficacy. WT and DARPP-32 KO mice were injected with fluoxetine (5 or 10 mg/kg) 30 min before the trial. The trial was conducted for a period of 5 min, during which the duration of immobility was recorded. Data represents means ± SE for six to ten mice per experiment. #, P < 0.05, ##, P < 0.01 compared with saline; *, P < 0.05, ***, P < 0.001 compared with fluoxetine in DARPP-32 WT mice, two-way ANOVA followed by Duncan's test.
