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
8 samples: 4 × mouse-DRG-WT vs 4 × mouse-DRG-cKOGroups 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)
The 5-methylcytosine (m⁵C) RNA modification regulates multiple aspects of RNA metabolism; however, its contribution to pathological pain remains poorly understood. Here, we investigated the role of the m⁵C reader Alyref in a mouse model of complete Freund’s adjuvant (CFA)-induced chronic inflammatory pain. We observed a marked and sustained upregulation of Alyref in nociceptive neurons of the dorsal root ganglion (DRG) following CFA administration.

Conditional deletion of Alyref in NaV1.8⁺ nociceptive neurons significantly exacerbated thermal and cold hypersensitivity, mechanical allodynia, and hyperalgesia. These behavioral abnormalities were accompanied by pronounced activation of microglia and astrocytes in the spinal dorsal horn, along with elevated expression of proinflammatory mediators, indicating enhanced neuroinflammation and central sensitization. Mechanistically, Alyref directly binds to m⁵C-modified Ccn3 mRNA and promotes its nuclear export, thereby maintaining cytoplasmic Ccn3 expression in DRG neurons. Loss of Alyref impaired Ccn3 mRNA export, reduced Ccn3 expression, and was associated with increased level of MMP-9, a key mediator of neuroinflammatory pain signaling. Collectively, these findings identify Alyref as a protective regulator in chronic inflammatory pain by restraining neuroinflammation and limiting the emergence of neuropathic pain-like features. Our study highlights a previously unrecognized role of m⁵C-dependent RNA regulation in nociceptive sensitization and suggests Alyref as a potential therapeutic target for pathological pain.

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 GSE321975_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 PRJNA1429351 and SRA study SRP679840. Searching any of these in the dataset finder brings you back here.

Study design
4 × mouse-DRG-WT vs 4 × mouse-DRG-cKO

Supports a between-group comparison across 8 samples.

How we read this: 2 replicated groups read from 8 sample titles; they account for 8 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.
