AHR and Neoplasm of the lung: Canonical pathway analysis by IPA determined that Nrf2 effector genes in lung tumors overlaid multiple signal transduction mechanisms including predicted glutathione metabolism (12 out of 98 pathway molecules match, 12/98), oxidative stress response (14/183), aryl hydrocarbon receptor signaling (12/154), LPS/IL-1 mediated inhibition of RXR function (14/213), glioblastoma multiforme signaling (12/163), and others (Dataset S3).
