Meta-networks allow novel inferences. Systems approaches allow the generation of networks of genes based on common pathways or common evolutionary history, networks of drugs based on chemical similarity or similarity in biological effects, and networks of effects based on similar biological pathways and cellular compartments. The ability to link these three networks allows novel inferences.
