What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.
Organism
Mus musculus (mouse)
Samples
12 samples: 6 × Ctrl vs 6 × dKOGroups are read from the sample names, not from the paper. Check the list below.
Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.

Skeletal muscle stem cells modulate niche function in Duchenne muscular dystrophy mouse through YY1-CCL5 axisNature communications · 2025
Summary (written by the submitters)
Adult skeletal muscle stem cells (MuSCs), also known as satellite cells (SCs), are widely believed to be responsible for muscle regeneration, which is regulated by complex networks of intrinsic and extrinsic factors. Emerging evidence demonstrates extrinsic regulations from other cell types can significantly impact the regeneration process, especially in repetitive cycles of degeneration/regeneration environment.

Here, we demonstrate that the transcription factor (TF) Yin Yang 1 (YY1) deletion in MuSCs of mdx mouse induces CCL5 expression by alleviating the repressive effect on 3D structural interactions on Ccl5 locus. This leads to the increased secretion of CCL5 from MuSCs to the muscle niche, which promotes the recruitment of macrophages (MPs) through the CCL5/CCR5 axis. Incremental MPs lead to continuous inflammation that promotes the survival of Fibro-adipogenic progenitors’ (FAP) through secreting elevated TGFβ1 to stimulate FAPs resisting apoptosis, resulting in aggravated dystrophic pathology manifested by exacerbated fibrosis. Inhibition of CCL5/CCR5 axis by Maraviroc injection effectively mitigates muscle dystrophy and enhances muscle performance in YY1 deletion mdx mouse. Altogether, our findings promote us to conclude that YY1 functions as a 3D structural protein to repress Ccl5 production at the transcriptional level in MuSCs, playing a critical role in orchestrating MuSC/MP/FAP crosstalk through CCL5/CCR5 and TGFβ1 signaling. Intrinsic deletion of YY1 in MuSCs disrupts the cellular interactions and leads to skewed muscle niche with aggravated muscle dystrophy upon chronic injury.

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 GSE250202_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: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1052661 and SRA study SRP478164. Searching any of these in the dataset finder brings you back here.

Study design
6 × Ctrl vs 6 × dKO

Supports a between-group comparison across 12 samples.

How we read this: 2 replicated groups read from 12 sample titles; they account for 12 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.
