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
29 samples: 13 × BAP1 sample vs 9 × NF2 sample vs 7 × H3K27me3 loss sampleGroups 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.

Molecular signatures define BAP1-altered meningioma as a distinct CNS tumor with deregulation of Polycomb repressive complex target genesNeuro-oncology · 2025
Summary (written by the submitters)
Meningiomas are the most common primary intracranial neoplasms, exhibiting diverse patient outcomes. Despite most meningiomas being benign, a significant subset recurs postoperatively, posing substantial treatment challenges. Through an integrative analysis of DNA methylation data from over 10,000 meningioma samples, we identify BAP1-altered meningiomas as a molecularly distinct and biologically aggressive CNS tumor subtype, characterized by recurrent loss of chromosome 3p21 around the BAP1 locus and driven by diverse BAP1-inactivating alterations.

While BAP1-altered meningiomas often exhibit rhabdoid morphology, this feature is not exclusive to them and should not serve as a definitive grading criterion. However, progression-free survival analysis indicates that patients with BAP1-driven meningiomas have a prognosis similar to WHO grade 3 meningiomas. Gene expression profiling reveals upregulation of PRC target genes and dysregulated Polycomb signaling, alongside elevated expression in various cellular and growth factor pathways. This molecular portrait of BAP1-altered meningiomas underscores potential pathway-specific therapeutic targets that should be prioritized for future investigation

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 GSE287322_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 PRJNA1212133 and SRA study SRP559773. Searching any of these in the dataset finder brings you back here.

Study design
13 × BAP1 sample vs 9 × NF2 sample vs 7 × H3K27me3 loss sample

Supports a between-group comparison across 29 samples.

How we read this: 3 replicated groups read from 29 sample titles; they account for 29 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.
