EGFR and acute myeloid leukemia: KEGG pathway enrichment identified significantly activated signaling networks in AML, including MAPK, Rap1, phospholipase D, sphingolipid, and ErbB signaling pathways, some neurological pathways (axon guidance, oxytocin/dopaminergic/glutamatergic synapses, circadian rhythm regulation, morphine addiction), and some immune-inflammatory pathways (chemokine signaling and Fcγ receptor-mediated phagocytosis).
