Tcf4 Regulates Synaptic Plasticity, DNA Methylation, and Memory Function.

ABSTRACT: Human haploinsufficiency of the transcription factor Tcf4 leads to a rare autism spectrum disorder called Pitt-Hopkins syndrome (PTHS), which is associated with severe language impairment and development delay. Here, we demonstrate that Tcf4 haploinsufficient mice have deficits in social interaction, ultrasonic vocalization, prepulse inhibition, and spatial and associative learning and memory. Despite learning deficits, Tcf4(+/-) mice have enhanced long-term potentiation in the CA1 area of the hippocampus. In translationally oriented studies, we found that small-molecule HDAC inhibitors normalized hippocampal LTP and memory recall. A comprehensive set of next-generation sequencing experiments of hippocampal mRNA and methylated DNA isolated from Tcf4-deficient and WT mice before or shortly
