摘要：Abstract. The present study explored the impact of Akt1 and Akt3 on behavior. Akt1 ( akt1 -/- ) and Akt3 ( akt3 -/- ) knockout mice were compared to wild type ( wt ) mice. The akt1 -/- mice, akt3 -/- mice, and wt mice were similar in most parameters of the open-field test. However, the distance traveled in the center area was slightly but significantly less in akt3 -/- mice than in wt mice. In the light/dark transition test akt1 -/- mice had significantly lower values than wt mice and akt3 -/- mice for distance traveled, number of rearings, rearing time in the light area, as well as time spent and distance traveled in the entrance area. They were significantly different from akt3 -/- mice in the distance traveled, visits, number of rearings, rearing time in the light area, as well as time spent, distance traveled, number of rearings, and rearing time in the entrance area. In the O-maze the time spent, and the visits to open arms, as well as the number of protected and unprotected headdips were significantly less in akt1 -/- mice than in wt mice, whereas the time spent in closed arms was significantly more in akt1 -/- mice than in wt mice. Protected and unprotected headdips were significantly less in akt3 -/- mice than in wt mice. In closed area, akt3 -/- mice traveled a significantly larger distance at larger average speed than akt1 -/- mice. No differences were observed between akt1 -/- mice, akt3 -/- mice and wt -type mice in the time of floating during the forced swimming test. In conclusion, akt1 -/- mice and less so akt3 -/ mice display subtle changes in behavior. Keywords: open-field test , light/dark transition test , O-maze , forced swimming test
