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
21 samples: 7 conditions, mostly in triplicateGroups 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.
Paper
ATAD2 mediates chromatin-bound histone chaperone turnovereLife · 2026
Summary (written by the submitters)
H2A.L.2 is a specific variant of the H2A histone that accumulates late in the post-meiotic stages of mouse spermatogenesis, coinciding with the appearance of transition proteins (TPs). Since TP accumulation occurs during a period of general transcriptional shutdown, we hypothesized that the accumulation of TP and H2A.L.2 would not influence the transcriptome of condensing spermatids.

To test this hypothesis, we isolated total RNA from fractionated mouse spermatogenic cells, including spermatocytes, round spermatids, and condensing spermatids. We then generated transcriptomes from both wild-type cells and cells deficient in H2A.L.2. Analysis of these transcriptomes confirmed our hypothesis, showing no significant differences in gene expression between cells with or without H2A.L.2. These findings suggest that H2A.L.2 plays a structural role in the nucleosome-to-protamine transition rather than a regulatory role in 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 GSE284749_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 PRJNA1200601 and SRA study SRP552648. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 20 samples.

How we read this: 7 replicated groups read from 21 sample titles; they account for 20 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.
