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.

Inhibition of PAK2 in endothelial cells suppresses tumor angiogenesis and promotes immune sensitization through CXCL10Cell reports · 2026
Summary (written by the submitters)
Tumor angiogenesis is driven by pro-angiogenic factors and results in a disorganized tumor vasculature that limits effective perfusion and immune infiltration. The p21-activated kinase 2 (PAK2) regulates endothelial cell (EC) migration, an essential step of angiogenesis, yet its role in tumor angiogenesis remains ill-defined. Here, we show that endothelial-specific deletion of PAK2 in orthotopic tumor mouse models markedly reduces tumor size and angiogenesis.
Read the full summary ↓
Loss of endothelial PAK2 also normalizes the remaining tumor vasculature and promotes infiltration of dendritic and NK cells. Mechanistically, PAK2 regulates chemokine expression, notably CXCL10. PAK2 depletion enhances CXCL10 secretion from ECs, and CXCL10 expression is required for the inhibitory effects of PAK2 silencing on EC spouting. Moreover, CXCL10 neutralization in mice reverses the vascular and immune changes induced by endothelial PAK2 deletion. Together, these findings identify endothelial PAK2 as a potential target to limit tumor angiogenesis and reprogram ECs to promote immune infiltration through CXCL10 signaling.

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 GSE312096_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 PRJNA1372162 and SRA study SRP650328. Searching any of these in the dataset finder brings you back here.

Study design

Supports a between-group comparison across 12 samples.

How we read this: 4 replicated groups read from 24 sample titles; they account for 12 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.
