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: 4 × Sedentary vs 4 × A vs 4 × ARExGroups 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.
Summary (written by the submitters)
Objective To investigate the effects of low-intensity exercise on active arthritis in a SKG mouse model of human rheumatoid arthritis (RA) pathology. Methods Twenty-four female SKG mice were divided into three groups: sedentary (control), AR (induced arthritis), and AREx (induced arthritis plus low-intensity exercise). Arthritis was induced via intraperitoneal administration of mannan.

After a 2-week inflammation period, low-intensity treadmill exercise was performed only in the AREx group. Arthritis was assessed weekly during the rearing period. After 4 weeks of exercise, histological and bone morphometric analyses of the right ankle joint were performed. A histological analysis of the gastrocnemius muscle was also performed. Bulk mRNA sequencing was conducted on the left synovial membrane-fat pad (SM-FP) complex. Results The synovitis score showed no change; however, the arthritis score was significantly lower in the AREx group than in the AR group (p<0.05), indicating that low-intensity exercise suppressed arthritis exacerbation. The calcaneal and talar bone volumes decreased in the AR group, whereas the AREx group showed no significant change. In the SM-FP complex tissue, the gene expression of inflammatory cytokines decreased in the AREx group compared with the AR group, particularly the suppression of IL6/Jak/Stat3. Immunohistochemical analysis revealed significantly decreased expression of pro-inflammatory cytokines and increased expression of anti-inflammatory cytokines in the synovium of the AREx group compared with the AR group (p<0.05). Conclusion Low-intensity exercise therapy for active RA showed anti-inflammatory and suppressive effects on arthritis exacerbation in SKG mice, a mouse model of human RA pathology.

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 GSE271058_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 PRJNA1129519 and SRA study SRP516816. Searching any of these in the dataset finder brings you back here.

Study design
4 × Sedentary vs 4 × A vs 4 × AREx

Supports a between-group comparison across 12 samples.

How we read this: 3 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.
