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
8 samples: 4 × Control vs 4 × Sf1_5UTR_delGroups 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
Translational Regulation of Sf1 Integrates Alternative Splicing and Hematopoietic Stem Cell FateBlood · 2026
Summary (written by the submitters)
The transition of hematopoietic stem cells (HSCs) from quiescence to differentiation is essential for homeostasis. While transcriptomic control of this process has been extensively studied, the diversity of mRNA isoforms during exit from quiescence remains unexplored. Here, we identify a translationally regulated splicing program governing hematopoietic fate decisions.
Read the full summary ↓
Splicing factors involved in branch point recognition show dynamic protein-level regulation during HSC differentiation. Among them, Sf1 is translationally controlled via a conserved, structured 5′ UTR. Disrupting translation regulation of Sf1 skews differentiation toward stem cell and erythroid programs. Sf1-dependent alternative splicing affects 5′ UTRs of hematopoietic and DNA damage response genes, altering their translation and impairing DNA damage resolution. These findings reveal an unrecognized link between translational control of spliceosome components, alternative splicing, and HSC fate decisions.

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 GSE294393_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 PRJNA1249375 and SRA study SRP577761. Searching any of these in the dataset finder brings you back here.

Study design
4 × Control vs 4 × Sf1_5UTR_del

Supports a between-group comparison across 8 samples.

How we read this: 2 replicated groups read from 8 sample titles; they account for 8 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.
