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
16 samples: 3 × In vivo cardiac fibroblasts from mice treated with angiotensin II/phenylephrine - control vs 3 × In vivo cardiac fibroblasts from hearts with no injury - control vs 3 × In vivo cardiac fibroblasts from hearts with no injury - cardiac fibroblasts with loss of TCF21 vs 2 × In vivo cardiac fibroblasts from mice treated with angiotensin II/phenylephrine - TCF21 overexpressoGroups 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)
Transcription factor 21 (TCF21) is a basic helix-loop-helix protein required for developmental specification of cardiac fibroblasts from epicardial progenitor cells that normally surround and invade the heart. In the adult heart, TCF21 is expressed in tissue resident fibroblasts but is downregulated in response to injury or stimuli leading to myofibroblast differentiation.
Read the full summary ↓
These findings led to the hypothesis that Tcf21 could be a regulator of fibroblast cell-fate in the adult mammalian heart and contribute to cardiac fibrosis. Here, bulk RNA sequencing was used to determine the effect of loss of TCF21 and enforced TCF21 expression in adult cardiac fibroblasts.

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 GSE261166_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 PRJNA1085669 and SRA study SRP494128. Searching any of these in the dataset finder brings you back here.

Study design
3 × In vivo cardiac fibroblasts from mice treated with angiotensin II/phenylephrine - control vs 3 × In vivo cardiac fibroblasts from hearts with no injury - control vs 3 × In vivo cardiac fibroblasts from hearts with no injury - cardiac fibroblasts with loss of TCF21 vs 2 × In vivo cardiac fibroblasts from mice treated with angiotensin II/phenylephrine - TCF21 overexpresso

Supports a case/control comparison: 4 samples read as cases, 3 as controls.

How we read this: 4 replicated groups read from 16 sample titles; they account for 11 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.
