The service, Integrating Network Objects with Hierarchies (INOH), provides access to a database of pathways among bio-molecules in several organisms, including humans, mice, and rats. The pathways recorded by the service define molecular connections that allow signal transduction in an organism. This information is documented largely in published articles, so the database is built by extracting knowledge from text to develop a machine-processable repository.
API methods support retrieval of graphs defining nodes and arcs (or edges) connecting them, based on selected criteria. Results delivered include the nodes involved in a particular pathway and the connections between them, distinguished by event type, including controlled events, controlling events, and others.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
