Single-cell RNA-seq · human · 10 samples

What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart.
Organism
Homo sapiens (human)
Samples
10 samples: 4 × Control Biopsy vs 4 × EGCG BiopsyGroups 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.
Paper
A fibroblast-dependent TGF-β1/sFRP2 noncanonical Wnt signaling axis promotes epithelial metaplasia in idiopathic pulmonary fibrosisThe Journal of clinical investigation · 2024
Summary (written by the submitters)
Trihydroxyphenolic compounds, such as Epigallocatechin Gallate (EGCG), cause fibroblast-specific TGFb1 receptor kinase and lysyl oxidase like 2 (LOXL2) inhibition, reducing fibroblast activation and collagen cross-linking in fibrotic mice lungs and in cultured human precision cut lung slices (PCLS) derived from Interstitial Lung Disease (ILD) / Idiopathic Pulmonary Fibrosis (IPF) patients.
Read the full summary ↓
When taken for two weeks, EGCG reduced protein markers of pro-fibrotic signaling in spare tissue from diagnostic surgical biopsies from ILD patients. Here, we report the result of single-cell RNA sequencing on lung tissue from ILD patients who took EGCG (600mg by mouth daily) for two weeks prior to diagnostic surgical biopsy and donated spare tissue and from control/untreated biopsy samples, including comparison to normal donor and end-stage ILD explant lung tissues.

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 GSE239664_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: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1000503 and SRA study SRP452440. Searching any of these in the dataset finder brings you back here.

Study design
4 × Control Biopsy vs 4 × EGCG Biopsy

Supports a between-group comparison across 8 samples.

How we read this: 2 replicated groups read from 10 sample titles; they account for 8 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.
