Summary (written by the submitters)
After fertilization, early embryos undergo dissolution of conventional chromatin organization including topologically associating domains (TADs). Zygotic genome activation then commences amid unusually slow de novo establishment of three-dimensional chromatin architecture. How chromatin organization is established and how it interplays with transcription in early mammalian embryos remain elusive.

Here we show that CTCF occupies chromatin throughout mouse early development. By contrast, cohesin poorly binds chromatin in one-cell embryos, coinciding with TAD dissolution. Cohesin binding then progressively increases from two- to eight-cell embryos, accompanying TAD establishment. Unexpectedly, strong ‘genic cohesin islands’ (GCIs) emerge across gene bodies of active genes in this period. GCI genes enrich for cell identity and regulatory genes, exhibit broad H3K4me3 at promoters, and display strong binding of transcription factors and the cohesin loader NIPBL at nearby enhancers. We show that transcription is hyperactive in two- to eight-cell embryos and is required for GCI formation. Conversely, induced transcription can also create GCIs. Finally, GCIs can function as insulation boundaries and form contact domains with nearby CTCF sites, promoting both the transcription levels and stability of GCI genes. These data reveal a hypertranscription state in early embryos that both shapes and is fostered by the three-dimensional genome organization, revealing an intimate interplay between chromatin structure and transcription.

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 GSE200323_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA824060 and SRA study SRP367893. Searching any of these in the dataset finder brings you back here.
