SystemsBiologySBML
In systems biology field, most curated models are developed by for example CellDesigner, and are described in SBML format. Each model is publised in each paper, and in each SBML file. To integrate published models, semantic web approach is very useful. BioPAX provides a common exchange format for biological pathways and models in OWL. http://www.biopax.org/ Please see usecase (goal) as described below.
Datasets
- BioPAX http://www.biopax.org/
- BioModels? Database (EMBL-EBI) http://www.ebi.ac.uk/biomodels/ stores over 400 published systems biology models in not only SBML and but also BioPAX Level 2 OWL.
- Mol Syst Biol - Structural Data Archive (in SBML) http://www.nature.com/msb/sdata/index.html
- E-cell Model Repository - SBML Models http://www.e-cell.org/ecell-models/repository/SBML
- Model Format OWL (MFO) http://cisban-silico.cs.ncl.ac.uk/MFO/ is an alternative OWL.
- BioPAX problems are described in ESBML in OWL: some thoughts on Model Format OWL (MFO)
Convertor
BioPAX Level 3
No convertor now.
BioPAX Level 2
The convertor sbml2biopax from SBML to BioPAX OWL is provided by BioModels? Compneur Group.
The sbml2biopax requires libSBML, and it works with the latest libSBML (libsbml.4.0.1).
$ wget http://www.ebi.ac.uk/compneur-srv/sbml/convertors/sbml2biopax-1.3.tar.gz $ tar xvfz sbml2biopax-1.3.tar.gz; cd sbml2biopax-1.3; cp ~/mymodel.xml . $ sh sbml2biopax.sh mymodel.xml
$ wget http://www.nature.com/msb/journal/v1/n1/extref/msb4100014-s3.xml -O Oda_EGFR_2005.xml $ sh sbml2biopax.sh Oda_EGFR_2005.xml $ wget http://www.nature.com/msb/journal/v1/n1/extref/msb4100057-s1.xml -O Oda_TLR_2006.xml $ sh sbml2biopax.sh Oda_TLR_2006.xml
The sbml2biopax generate BioPAX Level 2 OWL file from given SBML file.

SPARQL end point

Usecase (goal)
Usecase is an integration of models, in other words, pathways. Each pathway is in each SBML file. However, as you know, pathways are closely related each other. For example, TMD systems biology group ( http://bioinfo.tmd.ac.jp/sysbio/) has developed a database for Alzheimer disease named AlzPathway?. AlzPathway? collects signaling pathways relevant to Alzheimer disease, however, these pathways are not exclusively relevant to Alzheimer disease; Alzheimer disease pathway is closely related to apoptosis pathway, and if someone published a model for apoptosis, an integration of AlzPathway? and apoptosis pathway will be very helpful for researchers in Alzheimer disease to obtain novel insight and hypothesis.
Problems & ToDo?
- BioPAX OWL might be too complicate to archive the above usecase (goal). SPARQL search might took so much time to return results. Appropriate reduction of information of SBML model is required to convert from SBML to RDF (not OWL).
- In the case of conversion from SBML to RDF, mapping of name among models is required.
Visualization
- RelFinder? in Virtuoso
- Cytoscape: Cytoscape 2.7.0 beta supports BioPAX Level 3 by Ono-san. See VisualizationAndInteraction.
- BioCichlid: BioCichlid? will support BioPAX Level 2 (now under implementing).
