Abstract <br></p>
<p>
<br>
</p>
<p>
<b>Background:
</b>Graph
databases can be successfully applied in Systems Biology and in
Systems Medicine for managing extensive and complex information.
Ultimately, graphs are a natural way of representing biological
networks. The use of graph databases enables efficient storing and
processing of biological relationships, and it can lead to a better
response time when querying the data.</p>
<p>
<br>
</p>
<p>
<b>Objectives:
</b>We
would like to use graph databases structure to store and explore
biological pathways and networks.</p>
<p>
<br>
</p>
<p>
<b>Method:</b>
Translation rules have been determined to represent biological
reaction networks in a graph model, that is to say as nodes,
relationships and properties. The reaction networks are provided in
the graphical standard Systems Biology Graphical Notation (SBGN). The
graph model is stored in a Neo4j database.</p>
<p>
<br>
</p>
<p>
<b>Results:
</b>We
present the Java-based framework STON (SBGN TO Neo4j) to import and
translate metabolic, signalling and gene regulatory pathways. On the
poster, we show examples of networks representing parts of the Asthma
Map, the iNOS pathway (a SBGN use case network).</p>
<p>
<br>
</p>
<p>
<b>Conclusion:
</b>STON
exploits the power of a graph database for the search in complex
biological pathways.
Importing biological pathways in a graph database enables:</p>
<p>
1)
identification of functional sub-modules and comparing different
networks in order to discover common patterns.
</p>
<p>
2)
merging multiple diagrams for creating large comprehensive networks
for empowering systems medicine approaches.</p>
