Interestingly, pathway analysis identified many tumor pathways (e.g., Hatada_Methylated_in_lung-cancer, Vecchi_Gastric_Cancer_early_DN, Dawson_Methylated_in_Lymphoma_TCL1, Rickman_Head_and_Neck_Cancer_A) including mixed lineage leukemia (MLL) pathway (Wang_MLL_Targets) and GvHD (KEGG_Graft_versus_Host_Disease; Fig. 6a). This evidence concerns the gene KMT2A and lung cancer.
