The A1 tumors were enriched for neuronal pathways (G3 genes), the A2 tumors were enriched for metal ion stress response (G1 genes) and wound healing pathways (G2 genes), the B tumors were enriched with synaptic pathways (G5 genes) and wound healing (G2 genes), while the supra-carcinoids were enriched for protein kinase and serine endopeptidase pathways (G4 genes) (gene ontology can be found in Fig. S4C and Table S7). This evidence concerns the gene WEE1 and carcinoid tumor.
