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
11 samples: 3 × KO-FOB vs 3 × WT-MZB vs 3 × KO-MZB vs 2 × WT-FOBGroups 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
Rack1 regulates B-cell development and function by binding to and stabilizing the transcription factor Pax5Cellular & molecular immunology · 2024
Summary (written by the submitters)
Transcription factor Pax5 activates genes essential for B-cell development and function. However, the regulation of Pax5 expression remains elusive. Adaptor Rack1 can interact with multiple transcription factors and modulate their activation and/or stability. Despite that, its role in the transcriptional control of B-cell fates is largely unknown.

Here we show that CD19-driven Rack1 deficiency leads to pro-B accumulation and simultaneous reduction of B cells at later developmental stages. The generation of bone marrow chimeras indicates a cell-intrinsic role of Rack1 in B-cell homeostasis. Moreover, Rack1 augments BCR and TLR signaling in mature B cells. Based on diminished CD19 expression upon Rack1 deficiency, further exploration reveals that Rack1 maintains Pax5 protein levels through direct interaction and consequent prevention of Pax5 ubiquitination. Accordingly, Mb1-driven Rack1 deficiency almost completely blocks B-cell development at the pro-B cell stage. Thus, Rack1 regulates B-cell development and function through, at least partially, binding to and stabilizing Pax5.

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 GSE273420_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 PRJNA1141703 and SRA study SRP523015. Searching any of these in the dataset finder brings you back here.

Study design
3 × KO-FOB vs 3 × WT-MZB vs 3 × KO-MZB vs 2 × WT-FOB

Supports a between-group comparison across 11 samples.

How we read this: 4 replicated groups read from 11 sample titles; they account for 11 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.
