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
16 samples: 4 × BMDM, cKO, PTX vs 4 × BMDM, cKO, DMSO vs 4 × BMDM, WT, PTX vs 4 × BMDM, WT, DMSOGroups 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)
Chemotherapy-induced peripheral neuropathy (CIPN) is the most prevalent and limiting side effect of paclitaxel treatment in cancer patients. CIPN affects sensory neurons through neuroinflammatory mechanisms, but how immune cells sense and interpret systemic paclitaxel exposure during treatment is unclear. Here, we report that paclitaxel administration triggers the endoplasmic reticulum (ER) stress sensor inositol-requiring enzyme 1α (IRE1α) in circulating and dorsal root ganglia-resident myeloid cells, engendering an inflammatory milieu that promotes CIPN.
Read the full summary ↓
Mechanistically, paclitaxel induced overproduction of mitochondrial-derived reactive oxygen species (ROS) that provoked ER stress and IRE1α hyperactivation in macrophages. This process reprogrammed macrophages towards a highly inflammatory state characterized by IRE1α-dependent production of TNF-α, IL-1β, PGE2, IL-6, IL-5, GM-CSF, MCP-1, and MIP-2. Ablation of IRE1α in leukocytes, or treatment with a selective IRE1α pharmacological inhibitor, prevented dorsal root ganglia neuroinflammation and CIPN-related pain behaviors in mice. Furthermore, the development and severity of CIPN in patients with gynecological cancer was associated with the status of IRE1α activation in their circulating leukocytes. Our study uncovers leukocyte-intrinsic IRE1α as a key mediator of CIPN and suggests that targeting its dysregulated activation could help mitigate CIPN in cancer patients receiving paclitaxel.

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 GSE309119_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 PRJNA1333999 and SRA study SRP626446. Searching any of these in the dataset finder brings you back here.

Study design
4 × BMDM, cKO, PTX vs 4 × BMDM, cKO, DMSO vs 4 × BMDM, WT, PTX vs 4 × BMDM, WT, DMSO

Supports a between-group comparison across 16 samples.

How we read this: 4 replicated groups read from 16 sample titles; they account for 16 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.
