Transcription factor NFYA directs male meiotic entry by regulating accessible chromatin at meiotic promoters in miceThe EMBO journal · 2026
Summary (written by the submitters)
Meiotic prophase I characterized by homologous recombination and synapsis is an intricate step for spermatogenesis. This process entails extensive changes to chromatin and transcription. Recent studies have revealed that prior to prophase I, accessible chromatin bound by paused Pol II at meiotic gene promoters is essential for their timely activation during later stages of prophase I.

However, the factor responsible for promoting accessible chromatin at meiotic gene promoters before entry into prophase I is unknown. Here, we discovered that NFYA expressed in pre-meiotic germ cells promotes accessible chromatin at meiotic gene promoters. Concordantly, conditional germline deletion of Nfya in male mice blocks meiotic entry. Functionally, our spatial and single-cell ATAC-seq data revealed that loss of NFYA in pre-meiotic cells disrupts accessible chromatin at meiotic gene promoters. Our study identifies a pioneer role for NFYA in facilitating permissive chromatin at meiotic gene promoters before meiosis, thereby controlling the timely activation of meiotic genetic program during later meiosis.

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 GSE295964_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 PRJNA1256871 and SRA study SRP582234. Searching any of these in the dataset finder brings you back here.

Study design
3 × CUT&Run (NFYA) of sorted leptotene/zygotene cells from adult testis, vs 3 × CUT&Run (NFYA) of sorted pachytene/diplotene cells from adult testis, vs 3 × CUT&Run (NFYA) of sorted Spermatogonia cells from adult testis,

Supports a between-group comparison across 9 samples.

How we read this: 3 replicated groups read from 13 sample titles; they account for 9 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.
