Paper
Integrin αV emerges as a potential therapeutic target with cautionary implications in thoracic aortic aneurysm and dissectionThe Journal of thoracic and cardiovascular surgery · 2026
Summary (written by the submitters)
Thoracic aortic aneurysm (TAA) is a perilous disease that can lead to aortic dissection (AD), the pathophysiological mechanisms of which remain largely elusive. To improve our understanding of the molecular mechanism underlying TAA, we conducted a tandem mass tag (TMT)-based proteomics analysis and identified two down-regulated proteins, integrin αV, and integrin αL, in serum samples from patients with type A aortic dissection.

We confirmed that integrin αV is extensively expressed in the aortic media, and its expression decreases after dissection, whereas the expression of integrin αL showed no significant alteration. Subsequently, by employing a mouse model of TAA induced by β-Aminopropionitrile (BAPN), we discovered that the mice treated with integrin αV inhibitors Cilengitide or SB273005 developed dramatically expansive ascending TAA, accompanied by exacerbated disorganization or loss of elastic fibers. Bulk RNA sequencing results further indicated that the treatment with integrin αV inhibitors exacerbates the pro-inflammatory response in mouse TAA development. These data suggest that integrin αV may be a novel target for TAA intervention. However, it also raises concerns about exposure to integrin αV inhibitors, which are conducted in serious cancer clinical trials, may pose a potential risk of developing aortic aneurysm (AA)/AD.

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 GSE280456_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 PRJNA1178646 and SRA study SRP541615. Searching any of these in the dataset finder brings you back here.
