NuRD-enabled CTCF-TET crosstalk orchestrates epigenome reprogramming and genome architectureMolecular cell · 2026
Summary (written by the submitters)
CCCTC-binding factor (CTCF) is an evolutionarily conserved transcription factor with diverse regulatory roles. Around stable CTCF binding sites, nucleosomes are highly ordered and DNA methylation is reduced, yet the mechanisms establishing and maintaining this epigenetic environment remain unclear. Utilizing an innovative eBioID method, we identified that virtually all subunits of the nucleosome remodeling and deacetylase (NuRD) complex are associated with CTCF in cells.

Further analyses revealed that the NuRD complex is necessary for the chromatin binding of CTCF, and emerges as a novel regulator of the genome architecture. Additionally, we discovered that MBD3-NuRD facilitates the recruitment of TET demethylases to CTCF sites, initiating local DNA demethylation essential for the activation of adjacent gene expression. Embryonic stem cells deficient in the NuRD complex showed impaired lineage commitment. In summary, this study elucidates a mechanism illustrating the interplay between CTCF binding and the epigenome including 3D genome organization and DNA methylation, with the NuRD complex serving as an indispensable mediator.

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

Raw reads on ENA ↗

What the files usually look like: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA777880 and SRA study SRP344561. Searching any of these in the dataset finder brings you back here.
