摘要
目的:探索3-磷酸肌醇依赖的蛋白激酶-1(3-phosphoinositide-dependent protein kinase-1,PDK1)在海马依赖的学习记忆中的作用。方法:采用Cre/Loxp系统条件性敲除了表达在背侧端脑中Emx1(empty spiracles homeobox 1)阳性神经细胞中的PDK1,利用聚合酶链式反应及行为学实验Morris水迷宫对PDK1敲除小鼠进行研究。结果:该系统确实能敲除海马中的PDK1,且敲除后的小鼠学习记忆能力明显下降。结论:PDK1敲除后影响了小鼠的学习记忆能力,PDK1在海马介导的学习记忆过程中有重要作用。
Objective: To investigate the function of 3-phosphoinositide-dependent protein kinase-1 (PDK1) in the hippocampus dependent learning and memory.Methods: We used the Cre-Loxp to knock out PDK1 in empty spiracles homeobox 1 (Emx1) positive cells conditionally,which is expressed in the dorsal telencephalon.PCR was used for genotyping and Morris maze was used to test the learning and memory of mice.Results: We found that the PDK1 knockout mice had weaker capacity of learning and memory associated with hippocampus.Conclusion: PDK1 plays an important role in the hippocampus-dependent learning and memory in mice.
