The Bader Lab is involved in a number of collaborative open-source bioinformatics projects designed to make biological pathway data easy to visualize and analyze.
Biological Network Analysis and Visualization Software
Cytoscape is a bioinformatics software platform for visualizing molecular interaction networks and integrating these interactions with gene expression profiles and other state data. Additional features are available as plugins. Plugins are available for network and molecular profiling analyses, new layouts, additional file format support and connection with databases. Plugins may be developed using the Cytoscape open Java software architecture by anyone and plugin community development is encouraged.
Biological Pathway and Network Database Software
cPath, an open source database and web application for collecting, storing, browsing and querying biological pathway data. cPath makes it easy to aggregate custom pathway data sets available in standard exchange formats from multiple databases, present pathway data to biologists via a customizable web interface, and easily export pathway data via a web service to third-party software for visualization and analysis. cPath is software only, and does not include new pathway information. Key features include: a built-in identity and reference service for identifying and annotating interactors; built-in support for PSI-MI and BioPAX standard pathway exchange formats; and a web service interface for searching and retrieving pathway data sets. Thorough documentation is available for all aspects of cPath. The cPath software is freely available under the LGPL open source license for academic and commercial use.
Pathway and Network Data
The Cancer Cell Map contains selected cancer related signaling pathways which you can browse or search. Biologists can browse and search the Cancer Cell Map pathways. View gene expression data on any pathway. Computational biologists can download all pathways in BioPAX format for global analysis. Software developers can build software on top of the Cancer Cell Map using the web service API. Download and install the cPath software to create a local mirror.
Data Exchange Standards
BioPAX (Biological Pathway Exchange) is a collaborative effort to create a data exchange format for biological pathway data. BioPAX covers metabolic pathways, molecular interactions and protein post-translational modifications. Future versions will expand support for signaling pathways, gene regulatory networks and genetic interactions.
PSI-MI (The Proteomics Standards Initiative Molecular Interactions) format allows exchange of molecular interaction data, focusing on protein-protein interactions.
Community Web Sites
Pathguide, the Pathway Resource List, contains information about hundreds of online biological pathway resources. Databases that are free and those supporting BioPAX, CellML, PSI-MI or SBML standards are highlighted.
