In the “tradition” of Wikipedia and other wiki platforms, WikiPathways is intended to be an open, public space for content editing dedicated to biological pathways to facilitate pathway contributions and maintenance from the scientific community. Each WikiPathways page is focused on a single pathway, displaying the current version and references. A pathway can be edited by activating a webstart version of the pathway editing tool, PathVisio. PathVisio provides a basic palette of objects and annotation needed to represent biological processes, including gene objects which are directly mapped to biological annotations from any source through an extensible identifier synonym database. PathVisio is actively being developed by members of Chris Evelo’s group (BiGCaT, University of Maastricht, The Netherlands) in collaboration with GenMAPP (Gladstone Institutes, UCSF). After editing is complete, the new version of the pathway is displayed on the wiki page along with an updated version of the underlying biological information in various pathway file formats. Pathway information downloaded in these formats can be used in applications such as GenMAPP, to analyze for example gene expression data.  While in beta, we are supporting the GenMAPP Pathway Markup Language (GPML) file format native to PathVisioGPML is an XML file format that is being developed to bridge the annotation-rich, curated style of GenMAPP pathways and the more structured, robust BioPAX format which is emerging as the community standard.

As WikiPathways evolves, we plan to produce an embedded version of PathVisio directly into the wiki pages, eliminating the need for a webstart application altogether. Analogous to Wikipedia, modifications to pathways will be recorded, thereby creating a revision history for each pathway and allowing visual comparison between different versions of a pathway.  We will also support additional pathway file formats to encourage exchange across current applications and research preferences. We also recognize that the success of WikiPathways will depend heavily on clear and fair standards with regards to handling competing opinions and controversial findings. During beta, we will be gaining critical experience on managing style guides, versions and disputes.  We are confident that WikiPathways will be a useful resource to the research community and provide a much needed forum for pathway curation.

What is WikiPathways

WikiPathways was established to facilitate the contribution and maintenance of pathway information by the biology community. WikiPathways is an open, collaborative platform dedicated to the curation of biological pathways. WikiPathways thus presents a new model for pathway databases that enhances and complements ongoing efforts, such as KEGG, Reactome and Pathway Commons. Building on the same MediaWiki software that powers Wikipedia, we added a custom graphical pathway editing tool and integrated databases covering major gene, protein, and small-molecule systems. The familiar web-based format of WikiPathways greatly reduces the barrier to participate in pathway curation. More importantly, the open, public approach of WikiPathways allows for broader participation by the entire community, ranging from students to senior experts in each field. This approach also shifts the bulk of peer review, editorial curation, and maintenance to the community.

Why Pathways

Biological pathways provide intuitive views of the myriad of interactions underlying biological processes. A typical signaling pathway, for example, can represent receptor-binding events, protein complexes, phosphorylation reactions, translocations and transcriptional regulation, with only a minimal set of symbols, lines and arrows. These powerful representations are essential tools, common among the textbooks and review articles that document any given field of biology. Making these tools available for computational methods of analysis will allow researchers to connect pathways to databases of biological annotations and experimental data, creating effective products of systems biology. Collecting and maintaining pathway information in a robust database, however, is an ongoing challenge.

How Does it Work

Each pathway at WikiPathways has a dedicated wiki page, displaying the current diagram, description, references, download options, version history, and component gene and protein lists. Any pathway can be edited from within its wiki page by activating an embedded pathway editor. After editing, an updated pathway image is displayed on the wiki page along with the version history and list of component genes and proteins. Users can easily monitor and undo changes, compare differences and search for overlapping pathways. Using the search feature, one can locate particular pathways by name, by the genes and proteins they contain, or by the text displayed in their descriptions and comments. One can also browse the collection of pathways with combinations of species names and ontology-based categories. The pathway content at WikiPathways is freely available for download in a variety of data and image formats, including GPML, which is a custom XML format compatible with pathway visualization and analysis tools such as Cytoscape, GenMAPP and PathVisio.

Who is Involved

WikiPathways is maintained by BiGCaT Bioinformatics (University of Maastricht) and the Conklin Lab at the Gladstone Institutes (University of California, San Francisco). The current WikiPathways team includes Thomas A.J. Kelder, Alexander R. Pico, Martijn van Iersel, Kristina Hanspers, Bruce R. Conklin and Chris T.A. Evelo.
