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.

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)
Irritable bowel syndrome (IBS) is a prevalent functional gastrointestinal disorder that significantly reduces patients' quality of life. However, current animal models have limitations in replicating the complex pathophysiology of IBS. In this study, we successfully developed a mouse model by mating intestinal epithelium-specific Cre tool mice with chemically modified human muscarinic acetylcholine receptor 3 (hCHRM3) mice, resulting in specific expression of the hCHRM3 in the intestinal epithelial cells.

Activation of the hCHRM3 with clozapine-N-oxide (CNO) mimicked IBS attacks. The model mice exhibited typical IBS symptoms such as diarrhea, pain, and visceral hypersensitivity, along with pathological changes like intestinal edema and inflammatory cell infiltration, and disruption of the intestinal mucosal barrier. RNA sequencing revealed significant differentially expressed genes between the model and control groups, with KEGG and GO enrichment analyses indicating significant enrichment of immune and inflammation-related pathways. Additionally, the model mice showed increased levels of short-chain fatty acids and imbalances in the diversity and composition of the gut microbiota. This new IBS mouse model effectively simulates the symptoms and pathological processes of human IBS, providing a powerful tool for in-depth research into the pathogenesis of IBS and the development of therapeutic strategies.

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 GSE289595_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 PRJNA1223801 and SRA study SRP564070. Searching any of these in the dataset finder brings you back here.

Study design
A cohort of 12 individual samples

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

How we read this: Sample titles run S1062 … S1097 and carry no group information.
