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
79 samples: 79 samples, each with a distinct title — no replicated groupsGroups 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)
Transcriptional induction coincides with the formation of various chromatin topologies, including loss and gain of physical interactions between promoters and enhancers. While strong evidence supports that gene activation is accompanied by a general increase in promoter-enhancer interactions, how these topological changes are coordinated across time and space with other types of interactions to collectively enable gene activation remains unresolved.

Here we combine chromatin conformation capture with the profiling of histone modifications and transcription during a finely resolved time-course of embryonic stem cell differentiation to determine how genome restructuring in 3D correlates with and informs transcriptional transitions. Our data indicates that genome restructuring follows only a few common patterns that are related to the magnitude of transcriptional induction. Using this approach we identify transiently formed interactions between gene promoters and distal regulatory elements for which we demonstrate by genetic deletion that they can contribute to the transcriptional induction of associated genes. Finally, using acute depletion of cohesin, we prevent the formation of early promoter-enhancer interactions, and show that this impairs the activation of corresponding genes, compatible with the possibility that early topological changes are instructive for transcription. Taken together, our study identifies the variety of typical topological changes during gene activation, detects an uncharacterized type of transcriptional enhancers and provides evidence that the earliest topological changes can affect the magnitude of gene activation. Our data agrees with the idea that the multitude of topological changes account for appropriate gene induction during cell differentiation.

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 GSE261066_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 PRJNA1085204 and SRA study SRP493822. Searching any of these in the dataset finder brings you back here.

Study design
79 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 79 sample titles: 79 distinct titles with little repetition. 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.
