Summary (written by the submitters)
Germ cells are unique in that they tailor chromatin toward generating totipotency. Accordingly, mammalian spermatogonia, including spermatogonial stem cells (SSCs) which constitute the source for male gametes, acquire distinctive chromatin organization with weak insulation, but the underlying mechanism remains unknown. Here, we show that STAG3, this far known to exclusively form meiotic cohesins, generates a mitotic cohesin for male germline nucleome programming in mice.
Read the full summary ↓
Due to its shorter chromatin residence, STAG3–cohesin attenuates topologically associating domains (TADs), rewires enhancer–promoter and Polycomb-mediated repressive interactions, and facilitates finer and more strengthened compartments, establishing a distinctive spermatogonial nucleome. Moreover, in the absence of STAG3–cohesin, SSCs show an impaired differentiation priming for spermatogenesis. Mitotic STAG3–cohesin is also expressed in human B cells and their malignant variations, promoting their propagation. Our findings on mitotic STAG3–cohesin elucidate a principle of male germline nucleome programming, demonstrate an unexpected mitotic role for STAG3 and might potentially improve understanding of human malignancies.

This dataset
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 GSE243959_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 PRJNA1020805 and SRA study SRP463013. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 92 samples.

How we read this: 44 replicated groups read from 92 sample titles; they account for 92 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.
