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
12 samples: 12 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
Prickle4 Drives Microenvironmental Remodeling and Resistance to Parp Inhibition in IDH-Mutant GliomaAdvanced science (Weinheim, Baden-Wurttemberg, Germany) · 2026
Summary (written by the submitters)
Mutations in isocitrate dehydrogenase (IDH) genes render affected gliomas sensitive to PARP inhibition due to epigenetic reprogramming of the DNA damage repair circuits. However, PARPi treated tumor eventually relapse. We report in this study that anti-angiogenetic agent lenvatinib efficiently cooperate with PARPi and the combination therapy induces marked tumor regression and significant extension of survival time.
Read the full summary ↓
Genomic study with PARPi and lenvatinib treated tumor samples uncovered that PARPi evokes global transcriptome changes that are overall pro-inflammatory, thus inducing tumor angiogenesis. We identified that prickle planar cell polarity protein 4 (Prickle4) as the specific mediator for PARPi induced neovascularization. Suppression of Prickle4 efficiently overcomes PARPi resistance in these tumors. Overall, multimodality therapy combining PARPi and anti-angiogenetic agents represents a feasible treatment that is of excellent potential for clinical applications.

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 GSE249818_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 PRJNA1050787 and SRA study SRP477182. Searching any of these in the dataset finder brings you back here.

Study design
12 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 12 sample titles: 12 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.
