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
Homo sapiens (human)
Samples
18 samples: 18 samples, each with a distinct title — no replicated groupsGroups 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
Immediate early splicing controls translation in activated T-cells and is mediated by hnRNPC2 phosphorylationThe EMBO journal · 2025
Summary (written by the submitters)
Immediate early genes have been known and studied for decades. Their fast and transient induction, which depends on phosphorylation cascades and is independent of de novo protein synthesis, orchestrates the cellular response to various stimuli. In this study we show that the same phosphorylation cascades also target the splicing machinery to induce an analogous splicing switch that we call immediate early splicing (IES).
Read the full summary ↓
We characterize hnRNPC2-controlled IES, which depends on the MEK-ERK pathway and the T cell specific PKCθ. This splicing switch mainly targets components of the translation machinery and contributes to reduced de novo protein synthesis early upon T cell activation, to coordinate extensive transcriptional and posttranscriptional changes in gene expression. Together, our data set a paradigm for fast and transient alternative splicing, the immediate cellular response to activation, and provide evidence for its functional relevance during T cell activation.

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 GSE271051_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 PRJNA1129497 and SRA study SRP516798. Searching any of these in the dataset finder brings you back here.

Study design
18 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 18 sample titles: 18 distinct titles with little repetition. 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.
