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
16 samples: 5 × B1a_KO vs 4 × B1a_WT vs 4 × B2_WT vs 3 × B2_KOGroups 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.

Posttranscriptional control of the B cell receptor by HuR is essential for innate B cell maintenance and functionProceedings of the National Academy of Sciences of the United States of America · 2025
Summary (written by the submitters)
Innate B-1 cells constitute a self-maintained layer of defence for early detection of bacteria, clearance of apoptotic cell debris and removal of autoantigens driving autoimmunity. B-1 cells are originated from foetal tissues but, as opposed to B-2 cells, the molecular mechanisms behind their development and homeostatic maintenance remain largely unknown.
Read the full summary ↓
Here we demonstrate that post-transcriptional regulation by the RNA binding protein HuR is essential for the homeostatic self-replenishment of innate B-1 cells, the expansion of B-1 cell clones targeting self-antigens and the production of natural autoantibodies. HuR KO B-1 cells fail to express the high levels of surface BCR, TACI and BAFFR required for tonic signalling and cell survival. Mechanistically, HuR binds to the 3’UTRs of mRNAs encoding these surface receptors and of pro-survival molecules, like BCL-2 and MCL-1, promoting their translation into protein. In summary, we reveal the need of post-transcriptional regulation in BCR expression, tonic signalling and homeostatic maintenance of functional B-1 cells.

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 GSE276801_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 PRJNA1159118 and SRA study SRP531787. Searching any of these in the dataset finder brings you back here.

Study design
5 × B1a_KO vs 4 × B1a_WT vs 4 × B2_WT vs 3 × B2_KO

Supports a between-group comparison across 16 samples.

How we read this: 4 replicated groups read from 16 sample titles; they account for 16 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.
