Area of Science:

Genomics
Bioinformatics
Systems Biology

Background:

Large-scale multi-tissue gene expression data generation is now feasible.
Traditional clustering methods fail to capture inter-tissue dependencies or tissue-specific characteristics.

Purpose of the Study:

To develop a novel Bayesian model-based clustering algorithm for multi-tissue gene expression data.
To improve the analysis of complex gene expression patterns across different tissues.

Main Methods:

Developed 'revamp', a Bayesian model incorporating prior physiological tissue similarity.
Applied revamp to multi-tissue gene expression data from the STockholm Atherosclerosis Gene Expression (STAGE) study.
Compared revamp's clusters with alternative methods for enrichment of protein-protein interactions.

Main Results:

Revamp identifies clusters with conserved and tissue-specific gene sets.
Revamp-inferred clusters show higher enrichment for tissue-dependent protein-protein interactions.
Revamp provides interpretable associations between gene expression and coronary artery disease processes.

Conclusions:

Revamp offers a superior approach for analyzing multi-tissue gene expression data.
The algorithm enhances biological interpretation of gene expression patterns.
Revamp facilitates discovery of disease-associated molecular mechanisms.
