Is there a web-server or software that can create a network between given signaling pathways? Imagine that we know about a number of pathways that are involved in a specific disease, now I would like to generate a network (topological net) between these pathways. In these networks, nodes are signaling pathways and edges indicates relationship between those pathways...
How would you like to define the relationship between pathways? Within a given pathway the edges which connect nodes are typically defined by coexpression relationships between the corresponding genes, or known interactions between the proteins, or by known co-operation some biochemical reaction, etc. What will be your measure for the relatedness between pathways. Is iPath along the lines of what you are looking for?
Please correct me if I am wrong here : Connection between nodes or relationship between pathways could be defined by subnetworks between any two pathways, for instance if you have two signaling pathways that proteins or genes of those two are connected ( it could be physical interaction or co-expression or even one protein that have same function in those two pathways) so they made a sub-networks, and we can consider them as a two nodes with at least one edge .
