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.

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.

Rapamycin Partially Reverts Cavernoma Endothelial Cell Phenotype and, When Combined With Lapatinib, Ameliorates Chronic LesionsJournal of cellular and molecular medicine · 2026
Summary (written by the submitters)
Brain microvascular endothelial cells (mBMEC) deficient in Ccm3 were used to model CCMs in vitro. Cells were treated with propranolol (10 µM) and rapamycin (100 nM) for various durations. RNAseq was employed to analyze gene expression. Propranolol did not significantly affect the CCM phenotype in mBMEC, failing to revert gene expression changes.
Read the full summary ↓
Rapamycin partially reversed gene expression changes caused by Ccm3 deficiency, affecting genes such as Nos3, Adamts1, and Thbs1, known to be important for cavernoma pathogenesis in endothelial cells deficient for Ccm3. Propranolol's lack of efficacy in brain endothelial cells raises questions about its mechanism of action and potential benefits in CCM treatment.

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 GSE298723_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 PRJNA1271011 and SRA study SRP589448. Searching any of these in the dataset finder brings you back here.
