GeneMANIA: Fast gene network construction and function prediction for Cytoscape.

Area of Science:

• Bioinformatics
• Systems Biology
• Computational Biology

Background:

• GeneMANIA is a web service that predicts gene function and identifies gene-gene interactions.
• Cytoscape is an open-source software platform for visualizing complex biological networks.

Purpose of the Study:

• To introduce the GeneMANIA Cytoscape app for constructing composite gene-gene functional interaction networks.
• To enable users to explore gene relationships and functional annotations within a network context.

Main Methods:

• The app takes a list of genes as input.
• It queries the GeneMANIA database (1800+ networks, 500M+ interactions) for related genes and functional annotations (Gene Ontology).
• Interactions are visualized in Cytoscape, with edges annotated by source publication or data.

Main Results:

• Users can generate networks showing genes functionally related to their input list.
• Networks incorporate functional annotations and detailed interaction source information.
• The app supports 8 common model organisms and allows user-imported data.

Conclusions:

• The GeneMANIA Cytoscape app provides a powerful tool for network-based gene function analysis.
• It integrates extensive interaction data into the Cytoscape environment for biological discovery.
• The app enhances the exploration of gene relationships across multiple species and datasets.
