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
46 samples: 8 conditions, mostly with about 6 replicates eachGroups 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)
Peripheral neuropathy (PN) is the most common microvascular complication of type 2 diabetes mellitus (T2D). However, a thorough understanding of the mechanisms underlying PN pathogenesis is currently lacking. Thus, the goal of the current study was to use system biology approaches to investigate the development and progression of PN in a high-fat diet (HFD)-induced mouse model of T2D.

Transcriptomic data sets from sciatic nerve (SCN) and dorsal root ganglia (DRG) tissue were collected from 12- and 36-week-old HFD-fed mice and analyzed using self-organizing map and differentially expressed gene analysis with functional enrichment. Consistent with prior literature, pathways related to immune function and inflammation, mTOR signaling, and lipid metabolism were dysregulated in the SCN and DRG of HFD-fed mice. Additionally, cell-type abundance analysis revealed changes in cell composition in the SCN and DRG of HFD-fed T2D mice over time, particularly in the SCN. Comparison of differentially expressed genes from the SCN of HFD-fed mice to transcriptomic data from human sural nerve further supported the role of inflammation, mTOR signaling, and lipid metabolism in PN. Results from this study provide the basis for mechanistic studies investigating nerve damage in T2D and support the development of mechanism-based treatment options for PN.

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 GSE225224_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 PRJNA934372 and SRA study SRP422330. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 46 samples.

How we read this: 8 replicated groups read from 46 sample titles; they account for 46 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.
