Figure 1

Ingenuity Pathway analysis generated Network 1 diagram. The networks are based on known protein-protein interactions and functional relations. Genes that are differentially expressed in the SAGE libraries are depicted in shades of red (upregulated) or green (downregulated); empty symbols represent network genes that were not differentially expressed in the SAGE libraries. TGFβ is inserted into the model to identify gene whose expression is modulated by TGFβ. The diagram to the right explains the relationship lines.
