Paper
Control of myeloid lineage fidelity and response to stimuli by ISWI-enforced nucleosome phasingImmunity · 2025
Summary (written by the submitters)
Control over the accessibility of the genomic cis-regulatory information is key for the accurate deployment of gene expression programs. Such control is exerted by the combined action of pioneer transcription factors and chromatin remodelers with different ability to alter nucleosome positioning and occupancy. Here we show that SMARCA5 ( SNF2H), a chromatin remodeler enforcing linker DNA length, controls spacing of nucleosomes adjacent to sites where the myeloid lineage determining and pioneer TF PU.1 is constitutively bound, without however affecting PU.1 binding.

Loss of SMARCA5 caused a widespread increase in the accessibility of sites for stimulus-regulated TFs, causing not only macrophage hyper-activation in response to inflammatory stimulation but also the induction of stimulus-inappropriate genes. SMARCA5 deficiency also determined the extensive increase in binding of C/EBPb to cognate sites normally not accessible in macrophages but instead exposed in white or brown adipogenesis. Overall, enforcement of nucleosome phasing by ISWI controls fidelity in both lineage specification and response to stimulation.

This dataset
Download · which file do I need?

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.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE289674_RAW.tar (it can run to tens of gigabytes).

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.

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 PRJNA1223923 and SRA study SRP564045. Searching any of these in the dataset finder brings you back here.

Study design
19 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 19 sample titles: 19 distinct titles with little repetition. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
