Visualisation of BioPAX Networks using BioLayout Express (3D)

Area of Science:

• Bioinformatics
• Computational Biology
• Systems Biology

Background:

• BioLayout Express (3D) is a network analysis tool for biological data visualization.
• It is widely used for analyzing gene expression data and biological pathways.

Purpose of the Study:

• To enhance BioLayout Express (3D) with the capability to import, merge, and display biological pathways and protein interaction networks.
• To integrate support for the BioPAX Level 3 standard exchange format.
• To provide users with a graphical interface for querying and visualizing biological data from the Pathway Commons database.

Main Methods:

• Implemented import and display functionalities for BioPAX Level 3 formatted data.
• Developed a graphical user interface for querying the Pathway Commons database using gene/protein or pathway names via the cPath2 client.
• Established a visualization scheme by mapping BioPAX entity types to graphical glyphs.
• Enabled 2D and 3D graph layout viewing, editing, and exporting within BioLayout Express (3D).

Main Results:

• Successfully integrated BioPAX Level 3 data import, merging, and display capabilities into BioLayout Express (3D).
• Users can now query Pathway Commons for specific pathways or interaction data based on various criteria.
• A defined visualization scheme allows for effective graphical representation of imported biological network data.
• Enhanced data exploration through interactive 2D and 3D graph layouts with editing and export options.

Conclusions:

• Version 3.2 of BioLayout Express (3D) significantly expands its utility for biological network analysis.
• The integration of BioPAX Level 3 and Pathway Commons querying facilitates comprehensive visualization and exploration of complex biological data.
• The tool provides a powerful platform for researchers studying gene expression, pathways, and protein interactions.
