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
26 samples: 11 conditions, mostly in duplicateGroups 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
ASF1B promotes erythropoiesis by regulating the establishment and enrichment of H3.3 nucleosomesNucleic acids research · 2026
Summary (written by the submitters)
To gain insight into ASF1A, ASF1B and HIRA function during erythropoiesis, RNA-seq was performed in murine erythroleukemia (MEL) cells, human umbilical cord-derived progenitor erythroid 2 (HUDEP2) cells and human CD34+ erythroid progenitor cells. Notably, depletion of ASF1A, ASF1B and HIRA with/without DMSO induction significantly reduced the expression of genes associated with erythroid differentiation. Meanwhile, depletion of ASF1A and ASF1B in HUDEP2 cells as well as depletion of ASF1B in CD34+ cells significantly reduced the expression of genes associated with erythroid differentiation.

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 GSE285838_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 PRJNA1206179 and SRA study SRP559498. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 22 samples.

How we read this: 11 replicated groups read from 26 sample titles; they account for 22 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.
