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
160 samples: 78 conditions, mostly in duplicateGroups 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)
Conventional laboratory mice housed under specific pathogen-free (SPF) conditions are the standard model in biomedical research. However, in the past years, many published results involving rodents have been considered irreproducible, raising concerns about the suitability of mice as model organisms. Emerging evidence indicates that variations in SPF microbiota contribute significantly to data variability across different laboratories.

Despite efforts to standardize the microbiota, current microbial consortia lack the complexity and resilience needed to replicate interactions in free-living mammals. We present a standardizable and feasible approach for transplanting natural gut microbiota from wildlings into conventional laboratory mice. After engraftment, these TXwildlings adopt a structural and functional wildling-like microbiota and host physiology toward a more mature immune system, with characteristics similar to those of adult humans. We anticipate that using wild mouse-derived microbiota as standard for laboratory mouse models will improve the reproducibility and generalizability of basic and preclinical biomedical research.

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 GSE287225_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 PRJNA1211647 and SRA study SRP557878. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 159 samples.

How we read this: 78 replicated groups read from 160 sample titles; they account for 159 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.
