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
45 samples: 45 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
Radiotherapy induces YTHDF2 in dendritic cells impairing cross-presentation and T cell functionThe Journal of experimental medicine · 2026
Summary (written by the submitters)
We reveal that ionized radiation (IR) induces the expression of m6A reader YTHDF2 in DCs with clinical significance, and the depletion of Ythdf2 in DCs augments the anti-tumor effect of RT. We observed that following IR, SPI-1 promotes the transcription of YTHDF2 in DCs. The IR-induced YTHDF2 in DCs directly targets and degrades m6A-binded Mfng, Aph-1b, and Aph-1c, which are essential for notch activation.
Read the full summary ↓
YTHDF2 blockades in DCs activates notch signaling to promote the expression of MHC-I family gene Gm8909, thus enhancing cross-priming of CD8+ T cells to afford amplified anti-tumor effect of RT. Pharmacological inhibition of YTHDF2 in DC vaccines contributes to RT efficacy in both local tumor control and distant metastasis suppression. Our findings identify IR-induced YTHDF2 as an immunosuppressor in DCs, reveal the mechanism for regulating anti-tumor immunity, and open a new path for the development of m6A-mRNA targeting therapies.

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 GSE309228_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 PRJNA1334374 and SRA study SRP627315. Searching any of these in the dataset finder brings you back here.

Study design
45 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 45 sample titles: 45 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.
