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.

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)
Fulminant myocarditis (FM) is an acute fatal disease characterised by myocardial inflammation. Our previous study identified soluble growth stimulation- expressed gene 2 (sST2) as a sensitive and specific biomarker for early diagnosis of FM. However, its function in FM remains unclear.In the present study, we observed a marked elevation of sST2 in the plasma and hearts of mice with FM induced by coxsackievirus B3 (CVB3) and explored the main cellular sources of sST2 in FM.

Moreover, using recombinant sST2 protein administration and unbiased transcriptomics analyses, we investigated the role and underlying mechanisms of sST2 in FM. Importantly, we found that sST2 has a novel non-classical function in cardiomyocytes, other than acting as an IL-33 decoy receptor. These findings reveal a novel role and action mechanism of sST2 in FM and suggest that sST2 may be a potential therapeutic target for FM.

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 GSE261940_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 PRJNA1089611 and SRA study SRP496473. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 20 samples.

How we read this: 7 replicated groups read from 20 sample titles; they account for 20 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.
