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
15 samples: 5 conditions, mostly in triplicateGroups 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)
This study explores the role of Ezh2 in delaying the activation of differentiation genes during the development of cerebellar granule neurons (GNPs) and in SHH subtype medulloblastoma. To investigate the epigenetic landscape, we performed chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq) on GNPs and medulloblastoma cells derived from Ptch1 heterozygous mice.

We profiled histone modifications and key regulatory proteins, including H3K27me3, H3K27ac, H3K36me3, H3K4me3, H3K4me1, H2Aubi119, Ring1b, and Pol2S5. Additionally, we conducted ATAC-seq to assess chromatin accessibility and MIRA-seq to study DNA methylation. This dataset aims to compare the epigenetic state of normal granule neuron progenitors with that of medulloblastoma cells, providing insight into how epigenetic mechanisms contribute to neuronal differentiation. We found that the inhibition of Ezh2-mediated H3K27 methylation represses differentiation in both GNPs and medulloblastoma cells.

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 GSE279346_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 PRJNA1172126 and SRA study SRP538154. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 15 samples.

How we read this: 5 replicated groups read from 15 sample titles; they account for 15 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.
