Precise modulation of BRG1 levels reveals features of mSWI/SNF dosage sensitivityNature genetics · 2025
Summary (written by the submitters)
ATP-dependent chromatin remodelers establish and arrange nucleosome distribution, modifying accessibility of DNA. Brg1 is exclusive ATPase subunit of mSWI/SNF complex. To understand the dosage dependent function of mSWI/SNF complex. We take an advantage of dTag system to precisely control abundancy of BRG1. We found overall Brg1-binding is sensitive to its abundance nevertheless OCT4-target or H3K27ac region, suggesting Brg1 genome-wide distribution rather than being actively recruited.

We also reveal open chromatin dependency on BRG1. The chromatin accessibility of super enhancer shows buffered response on depletion of BRG1, whereas weak enhancer is sensitive. Finally, transcriptomic analysis identified that transcription shows buffered dependencies on BRG1 loss. Overall, our results highlight kinetics differences of BRG1-binding to transcriptome underline BRG1 dosage-sensitive mechanism.

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 GSE294015_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 PRJNA1247795 and SRA study SRP577144. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 32 samples.

How we read this: 16 replicated groups read from 32 sample titles; they account for 32 of them. 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.
