The top three ranked networks identified by IPA from the entire transcripts of IR-induced radioresistant A549 cells.

<p>(A) Network for cell death, post-translational modification, and protein folding (score: 38). (B) Network for cellular development, connective tissue development and function, and cancer (score: 37). (C) Network for cell cycle, cellular development, and hematological system development and function (score: 37). Networks are displayed graphically as nodes (genes/gene products) and edges (biological relationships between the nodes). Intensity of the node color indicates the degree of regulation (red: up-regulation, green: down-regulation, white: not differentially expressed but related to this network).
