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
18 samples: 6 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
Tristetraprolin-mediated mRNA destabilization regulates basophil inflammatory responsesAllergology international : official journal of the Japanese Society of Allergology · 2025
Summary (written by the submitters)
Basophils play crucial roles in type 2 immune responses, such as chronic allergic inflammation and protective immunity against parasites. However, the molecular mechanisms regulating basophil activation and effector molecule production remain poorly understood. To investigate the role of RNA-binding proteins (RBPs), we first analyzed the gene expression of CCCH zinc finger proteins in antigen/IgE-stimulated basophils.

Among these proteins, we identified that Zfp36, encoding tristetraprolin (TTP), was the most significantly upregulated gene. Therefore, we focused on the functions of TTP in basophils. We generated TTP-KO mice using the CRISPR-Cas9 method and conducted bulk RNA-seq analysis of antigen/IgE-stimulated basophils from wild-type (WT) and TTP-knockout (TTP-KO) mice. TTP-KO basophils exhibited elevated mRNA expression of pro-inflammatory mediators, such as Il4, Il13, Areg, Ccl3, and Cxcl2, compared to WT basophils. These data suggest that TTP is a key regulator of basophil activation, controlling the mRNA expression of inflammatory mediators.

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 GSE272532_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 PRJNA1137305 and SRA study SRP520750. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 18 samples.

How we read this: 6 replicated groups read from 18 sample titles; they account for 18 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.
