Paper
Sex-specific expression and function of TRIM28 during mouse primordial germ differentiationiScience · 2025
Summary (written by the submitters)
Transposable elements are increasingly appreciated as regulatory elements in early mammalian development, especially in cells which exhibit pluripotency. Mammalian primordial germ cells (PGCs) must exit latent pluripotency in a process termed determination before they are competent to differentiate and enter sex-specific developmental programs.
Read the full summary ↓
Here, we find that determination is marked by large changes to the transposable element (TE) repertoire, a phenomenon driven by TRIM28, after which testicular and ovarian PGCs exhibit district transposable element repertoires. We find that loss of TRIM28 perturbs entry into determination as marked by expression of DAZL in a sex-specific manner, but does not result in a failure to downregulate markers of latent pluripotency, including SOX2 and NANOG in either sex. Despite downregulation of some early PGC markers, both ovarian and testicular PGCs fail to properly enter into their meiotic germ cell or prospermatogonial programs, respectively. Thus, we show that TRIM28-mediated reorganization of the TE repertoire is necessary to establish a PGC epigenome competent for proper germline commitment and gametogenesis.

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 GSE266172_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 PRJNA1106060 and SRA study SRP504776. Searching any of these in the dataset finder brings you back here.

How we read this: 8 replicated groups read from 31 sample titles; they account for 31 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.
