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.

18 samples: 18 samples, each with a distinct title — no replicated groupsGroups 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)
STAT3 is pivotal in controlling hyperinflammation and governing effector macrophage responses to inflammation, yet the precise mechanisms by which STAT3 mediates pathogen control and clearance remain unclear. Herein, we performed RNA sequencing in bone marrow derived macrophages (BMDMs) to investigate STAT3-mediated transcriptional regulation of LPS-induced inflammation.

Genome-wide profiling revealed significant enrichment of type-I interferon (IFN-I) associated genes and the IFN Gamma response pathway in Stat3-deficient BMDMs in homeostasis. We observed significant reduction in the expression of pathogen response genes and secretion of cytokines and chemokines associated with pathogen clearance in Stat3-deficient BMDMs upon LPS stimulation. Using BM chimeric mice with 20% Stat3-deficient hematopoietic cells infected with Citrobacter rodentium, we show that STAT3 is essential for preventing bacterial dissemination to tissues and regulating production of cytokines and chemokines related to immune cell recruitment and bacterial control. Stat3-deficient BMDMs infected with C. rodentium showed impaired ability to kill intracellular bacteria and demonstrated dampened expression of pathogen response genes. Further, IL-6 blockade subdued the intrinsic IFN signature in Stat3-deficient macrophages and rescued aberrant expression of pathogen response genes upon LPS stimulation, suggesting STAT3 restrains an aberrant autocrine IL-6 signal that deregulates macrophage-mediated pathogen control. Our data identifies novel functions for STAT3 in orchestrating an optimal microbial defense response, by promoting bacterial control and clearance in macrophages.

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 GSE282695_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 PRJNA1189814 and SRA study SRP547162. Searching any of these in the dataset finder brings you back here.

Study design
18 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 18 sample titles: 18 distinct titles with little repetition. 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.
