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
Homo sapiens (human)
Samples
19 samples: 6 × DNT cells, HC vs 5 × DNT cells, PBC_U vs 4 × DNT cells, PBC vs 4 × DNT cells, PBC_naiveGroups 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)
Primary biliary cholangitis (PBC) is an autoimmune liver disease of unknown pathogenesis. We find a decreased number and immunosupressive function of double nagative T (DNT) cells in PBC patients. To further unveil the mechanism by which suppressive function and quantity of DNT cells in PBC patients was impaired, we performed a whole-transcriptome analysis on DNT cells isolated from 13 PBC patients and 6 HCs.
Read the full summary ↓
Total RNA of DNT cells from HCs and PBC patients were isolated and assessed. Transcriptome sequencing libraries were then generated using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (NEB, USA) following manufacturer’s recommendations and sequenced on an Illumina Hiseq platform (Illumina, San Diego, CA). Differentially expressed genes with a fold change of >=2.0 and p < 0.05 between HC and PBC patients were submitted to GO and KEGG enrichment analysis. Thie biologic processes of GO enrichment analysis showed that cell co-stimulations, cell migration, apoptotic process, cell activation and cell cytotoxicity were enriched, which helped to explain the alterations in number and suppressive function of DNT cells between HCs and patients from a mRNA level. Meanwhile, we observed that T cell receptor signaling pathway was enriched in DEGS and all identified genes with GSEA. Additionally the leading-edge genes of this pathway exhibited downregulation in PBC patients, subsequently supported by real-time PCR. PIK3R1 and MAP3K8 exhibited more significant reduction in DNT cells from PBC patients.

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 GSE138888_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 PRJNA577687 and SRA study SRP225754. Searching any of these in the dataset finder brings you back here.

Study design
6 × DNT cells, HC vs 5 × DNT cells, PBC_U vs 4 × DNT cells, PBC vs 4 × DNT cells, PBC_naive

Supports a between-group comparison across 19 samples.

How we read this: 4 replicated groups read from 19 sample titles; they account for 19 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.
