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
10 samples: 5 × Control, E18-5-DRG, vs 5 × Wnt1, Cre-Dach1-flox-flox-E18-5-DRG,Groups 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.

Temporal refinement of Dach1 expression contributes to the development of somatosensory neuronsThe EMBO journal · 2025
Summary (written by the submitters)
During somatosensory neurogenesis, neurons are born in an unspecialized transcriptional state, with several transcription factors following a broad-to-restricted expression dynamic as development proceeds, supporting neuron subtype identities. The relevance of this temporal refinement remains however unclear, these broad-to-restricted transcription factors being selectively involved in neurons in which they are ultimately maintained.

Here we found that Dach1 encodes for a bona fide broad-to-restricted transcription factor retained and required in tactile somatosensory neurons. Within developing nociceptors, we demonstrate that Prdm12 contributes to Dach1 extinction. Using genetic approaches to prevent its temporal restriction during somatosensory development, we reveal that Dach1 refinement is a prerequisite for the appropriate transcriptional maturation of somatosensory subtypes from which it becomes ultimately excluded. These findings highlight the essential role played by Dach1 during somatosensory neuron development. They further demonstrate that the broad-to-restricted temporal pattern followed by several transcription factors is physiologically relevant to achieve appropriate transcriptional maturation of somatosensory neurons.

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 GSE270845_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.

Raw reads on ENA ↗

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.

Supports a between-group comparison across 10 samples.

How we read this: 2 replicated groups read from 10 sample titles; they account for 10 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.
