Some Examples of Networks
in Cytoscape

Networks in Ecology:
Food Webs

Put this food web into cytoscape:
An Ocean Food Web
Nodes = organisms
Edges/arrows = flow of energy
A Food Web:
Salmon
Nodes = organisms
Arrows represent
flow of energy
Cell Phone Network
Nodes = people/phones
Here we track
Edges = can call
the flow of
information
analogous to the
flow of energy
in a food web
Gene Networks, etc
Nodes can represent
genes, proteins, etc…
Edges can represent
interaction between stimuli
(such as presence of light
or sugar) and a receptor,
promoter, etc…
Network Model = helpful for large systems,
lots of information

interactions. A large molecular interaction network was integrated with 1615 yeast
deletion phenotypes gathered systematically in response to MMS exposure.
