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
24 samples: 8 × colon, KONAM vs 8 × colon, WTNAM vs 4 × colon, KO vs 4 × colon, WTGroups 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)
NAPRT-mediated deamidated biosynthesis of nicotinamide adenine dinucleotide (NAD), an essential electron carrier for hundreds of biochemical reactions in all living cells, mediates the diet-microbe-host NAD metabolic interaction in mice. To study the function of this metabolic pathway in vivo, we recently generated a mutant mouse strain (NAPRT KO) in which a 21-nt fragment that encodes 7 amino acids in the catalytic domain of NAPRT was deleted in all cells using the CRISPR/Cas9-mediated gene editing technology.

Our data showed that NAPRT KO mice are hypersensitive to DSS-induced colitis. To better understand this hypersensitivity at the molecular level, we analyzed transcriptomes of colon tissues from DSS-treated WT and NAPRT KO mice.

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 GSE271250_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.

Raw reads on ENA ↗

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 PRJNA1130524 and SRA study SRP517391. Searching any of these in the dataset finder brings you back here.

Study design
8 × colon, KONAM vs 8 × colon, WTNAM vs 4 × colon, KO vs 4 × colon, WT

Supports a between-group comparison across 24 samples.

How we read this: 4 replicated groups read from 24 sample titles; they account for 24 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.
