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.

21 samples: 6 conditions, mostly with about 4 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.
Paper
Neonatal-Inspired Reprogramming of Microglial Pan-Programmed Cell Death Enhances Regeneration in Adult Spinal Cord InjuryResearch (Washington, D.C.) · 2025
Summary (written by the submitters)
In adult mammals, dysregulated programmed cell death (PCD) following spinal cord injury (SCI) impairs regeneration by causing neuronal loss, exacerbating inflammation, and disrupting tissue repair. However, the complex interplay of PCD pathways necessitates the establishment of an SCI-specific diverse cell-death (pan-PCD) framework to quantify PCD dynamics and identify therapeutic targets.
Read the full summary ↓
Here, we found that, unlike adults, neonatal mammals exhibit superior regenerative capacity due to a balanced PCD response, making them a valuable model for mimicking pan-PCD levels to promote regeneration. To address this, we introduce "Thanatoset," a pan-PCD gene panel, to comprehensively profile cell death dynamics in SCI. Among various cell types, microglia were identified as key mediators of pan-PCD, exhibiting heightened susceptibility in adult mice. Through computational drug screening, we identified Withaferin A (WFA), a compound capable of reprogramming microglial PCD to a neonatal-like regenerative state. In vitro and in vivo experiments demonstrated that WFA modulates NF-κB signaling, reducing inflammation, improving motor function, decreasing scar formation, and facilitating neuronal recovery. These findings underscore the therapeutic potential of modulating pan-PCD to restore regeneration and improve SCI outcomes in adults.

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 GSE285895_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 PRJNA1206725 and SRA study SRP555378. Searching any of these in the dataset finder brings you back here.
