Research Question

"The abstract shows HDAC9 overexpression reduces Aβ deposition and improves synaptic deficits, but the underlying molecular pathways are not explained. Understanding these mechanisms is critical for developing HDAC9-targeted therapeutics for AD.

MEF2C-Dependent Synaptic Gene Regulation

HDAC9 overexpression restores synaptic function through MEF2C-dependent transcriptional activation of neuroprotective genes (BDNF, SYP). STRING analysis confirms direct HDAC9-MEF2C interaction, and enrichment analysis shows HDAC9/MEF2C co-enrichment in synapse assembly and neuron survival pathways.
