背景记忆的快速编码需要海马CA3区,但必要的遗传途径仍不清楚。我们发现,活性依赖性转录因子Npas4调节CA3中的转录程序,这是上下文记忆形成所必需的。Npas4在情境学习后的CA3中特异性表达。CA3中Npas4的整体敲除或选择性缺失均导致背景记忆受损,并且CA3中Npas4的恢复足以逆转整体敲除小鼠中的缺陷。Npas4通过将RNA聚合酶II募集到靶基因的启动子和增强子中,调节CA3中的学习特异性转录程序,该程序包括许多众所周知的活性调节基因,这表明Npas4是活性调节基因程序的主调节器,并且是记忆形成的核心。
The rapid encoding of contextual memory requires the CA3 region of hippocampus, but the necessary genetic pathways remain unclear. We found that the activity-dependent transcription factor Npas4 regulates a transcriptional program in CA3 that is required for contextual memory formation. Npas4 was specifically expressed in CA3 after contextual learning. Global knockout or selective deletion of Npas4 in CA3 both resulted in impaired contextual memory, and restoration of Npas4 in CA3 was sufficient to reverse the deficit in global knockout mice. By recruiting RNA polymerase II to promoters and enhancers of target genes, Npas4 regulates a learning-specific transcriptional program in CA3 that includes many well-known activity-regulated genes, suggesting that Npas4 is a master regulator of activity-regulated gene programs and is central to memory formation.
