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
42 samples: 14 conditions, mostly in triplicateGroups 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.

Synovial MS4A4A correlates with inflammation and counteracts response to corticosteroids in arthritisProceedings of the National Academy of Sciences of the United States of America · 2025
Summary (written by the submitters)
MS4A4A belongs to the MS4A tetraspan protein superfamily and is selectively expressed by the monocyte-macrophage lineage. In this study, we aimed to evaluate the role of MS4A4A+ macrophages in rheumatoid arthritis (RA) pathogenesis and response to treatment. RNA sequencing and immunohistochemistry of synovial samples from either early treatment-naïve or active chronic RA patients showed that MS4A4A expression positively correlated with synovial inflammation.

Synovial macrophages from patients treated with corticosteroids (CS: Dexamethasone) exhibited an enhanced expression of MS4A4A and Fc γ receptor (FcγR) 3. Accordingly, CS enhanced in vitro the expression of MS4A4A and FcγR3 in human and murine macrophages. In an experimental model of arthritis, Ms4a4a deletion had no effect on the diseases course, but was associated with enhanced therapeutic response selectively to CS. These results suggest that macrophage expression of MS4A4A represents a novel biomarker of joint inflammation in RA and that its upregulation in concert with FcgR3 by CS counteracts the therapeutic activity of these drugs. Macrophage MS4A4A may represent a novel biomarker of joint inflammation in RA and a target to amplify the therapeutic activity of corticosteroids.

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 GSE302355_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 PRJNA1290242 and SRA study SRP600090. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 42 samples.

How we read this: 14 replicated groups read from 42 sample titles; they account for 42 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.
