CCZ1-MON1A improves exploratory behavior, spatial learning, and memory acquisition in 3xTg mice. (A-B) The spatial memory of WT or 3xTg mice receiving AAV injection was evaluated by morris water maze (MWM). Training trials (60 sec each) were performed 4 times a day for 5 days and the time for mice to find the platform was recorded. After 5 days training, the platform was removed and the time that mice stay in the platform quadrant was recorded. Data are quantified as mean ± SEM (n = 9). *P < 0.05, **P < 0.01 vs. the relative control, ns, not significant. (C-D) Short-term memory was test by Y-maze. The time that the mice spent in new arm was recorded. Data are quantified as mean ± SEM (n = 9). *P < 0.05, **P < 0.01 vs. the relative control. (E-F) The anxiety behavior was measured by open field test. The time that the mice spent in the center of the box was recorded. Data are quantified as mean ± SEM (n = 9). *P < 0.05, **P < 0.01 vs. the relative control.
