ARNT and cancer: In addition to ARNT, AHRR and genes encoding nuclear receptors (n = 6), genes reported in the literature to be involved in AHR signaling pathways, and various well known cancer pathways, including angiogenesis (n = 1), cell proliferation (n = 4), epithelial-mesenchymal transition (EMT) (n = 4), cell motility (n = 6), IGF pathway (n = 5), inflammation (n = 10), chromatin structure regulation (n = 5), DNA repair (n = 1), and upstream and downstream metabolism of AHR signaling (n = 3 and n = 8, respectively) were also analyzed (Table 4).
