It is shown that neuronal activation triggers genome-wide redistribution of CBP and p300 in hippocampal neurons, and KAT3 redistribution is identified as a key mechanism coupling neuronal activity to large-scale chromatin remodeling.
Abstract Neuronal activity induces widespread changes in chromatin organization, yet the mechanisms of activity-dependent 3D genome remodelling remain incompletely understood. Here, we identify SATB2 as a key regulator of activity-dependent 3D chromatin dynamics in cortical pyramidal neurons. Using primary cultures fro...

The findings uncover a non-canonical mechanism whereby a chromatin remodeler regulates transcription primarily through three-dimensional genome organization rather than local accessibility control, and establish histone modification-guided chromatin remodeling as a key principle in gene regulation.

These findings reveal a previously unrecognized role for PRCs in establishing TAD-scale repressive chromatin domains during neuronal maturation, thereby safeguarding neuronal identity from external stimuli through broad silencing of alternative cell fate programs.
The development of the cerebral cortex requires precise temporal control of transcription factor (TF) activity to coordinate neuronal and glial lineage transitions. However, the molecular mechanisms coupling signaling dynamics to TF function remain unclear. Here, we combine proteomic, phosphoproteomic, and multi-omic...

Abstract LIN28A is a conserved RNA-binding protein essential for pluripotency, let-7 miRNA regulation, and cellular metabolism. However, the mechanisms controlling its transcriptional activation during early stem cell fate transitions remain poorly defined. Using the Lin28a locus as a model, we identified multiple intr...
Enhancers integrate combinatorial inputs from sequence-specific transcription factors (TFs) and their activity must be calibrated to achieve precise spatiotemporal control of transcript dosage. Here we demonstrate that the sequence-specific repressors SNAI1 and SNAI2 (i.e. SNAIL and SLUG) quantitatively tune enhancer a...
