Figure 5. Customized gene network based upon the six most highly upregulated limbal epithelial cell genes. We explored possible functional relationships between the six highest upregulated limbal epithelial cells genes (in red) using the IPKB. Our customized pathway contained nodes composed of genes/gene products and edges that indicated a relationship between the nodes in the cellular and subcellular locations indicated. White indicates that the molecule was added from the IPKB.
