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
36 samples: 12 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
TAF1 is required for fetal but not adult hematopoiesis in miceDevelopmental cell · 2025
Summary (written by the submitters)
While many sequence-specific transcription factors (TFs) have been identified as key regulators of hematopoietic stem cell (HSC) lineage determination, the function of general TFs in HSC behavior is poorly understood. To evaluate the function of the TFIID subunit TAF1 in normal hematopoiesis, we generated Taf1 conditional knockout mice and identified an essential role of TAF1 in fetal erythropoiesis.
Read the full summary ↓
Surprisingly, TAF1 deletion in adult mice was not lethal to hematopoiesis; rather, we observed a marked expansion of the hematopoietic stem and progenitor cell (HSPC) compartment, with increased self-renewal and impaired differentiation capacity in these cells. TAF1-null HSPCs failed to produce mature blood cells in chimeric mice; these cells also failed to up-regulate key differentiation genes when induced to differentiate in vitro. TAF1 loss not only disrupted TFIID assembly and chromatin recruitment, but also reduced RNAPII promoter-proximal pausing. Thus, HSPCs utilize distinct transcriptional regulatory mechanisms to undergo differentiation versus maintaining self-renewal.

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 GSE248654_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 PRJNA1045523 and SRA study SRP474371. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 36 samples.

How we read this: 12 replicated groups read from 36 sample titles; they account for 36 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.
