Researchers Released Open-Source EndoMT Gene Resource
A new R package provides standardized gene sets for analyzing endothelial-to-mesenchymal transition in transcriptomic data.
Updated on Oct. 5, 2026 in Life Sciences
Researchers have released an open-source EndoMT R package containing a literature-informed gene set for transcriptomic enrichment analysis. This research-stage resource is now available to help scientists standardize the study of endothelial-to-mesenchymal transition.
Why it matters
The lack of a consistent, general-purpose gene set has historically hindered comparative research into EndoMT. This new tool addresses that gap by providing standardized signatures for analyzing gene expression data.
The package provides gene sets as Gene Matrix Transposed files and R objects, with genes explicitly assigned to either EndoMT UP or EndoMT DOWN expression signatures. The tool was validated using 4 distinct RNA-seq data sets to ensure utility in transcriptomic enrichment analysis.
The details
The resource functions by categorizing genes based on directional expression during EndoMT—a biological process where endothelial cells, which line the interior surface of blood vessels, lose their specific markers and acquire mesenchymal properties typical of connective tissue cells. Researchers curated this literature-informed set to allow for automated, standardized annotation of marker subtypes. The package integrates these signatures directly into R, a programming language and software environment for statistical computing, to streamline data interpretation.

The Tech Race
The EndoMT package leverages standardized data indexed in the Gene Expression Omnibus to establish its validation metrics. This tool extends the utility of existing public repositories by providing a curated analysis layer for data already hosted within the database.
Computational biologists and researchers working with transcriptomic data can now integrate these R objects into their existing analytical pipelines. The resource is available as an open-source package to facilitate broader adoption in studies of vascular biology and disease modeling.
The takeaway
Standardization is crucial for reproducible transcriptomic research, and this resource offers a starting point for consistent EndoMT signature analysis. Researchers should track future benchmarking studies that apply this tool to broader, tissue-specific RNA-seq data sets.
