Gene regulatory network: two genes are connected if the expression of one gene modulates expression of another one by either activation or inhibition

Node represents a gene;
Directed edge stands for the modulation (regulation) of one node by another:
e.g. arrow from gene X to gene Y means gene X affects expression of gene Y


Protein interaction network: proteins that are  connected in physical interactions or metabolic and signaling pathways of the cell;

Metabolic network: metabolic products and substrates that participate in one reaction;
