Moreover, the phagocytosis-related and immune-response pathways were significantly enriched in mice with IL-33 administration, as detected by Gene Ontology (GO) (GO: 0006911, GO: 0006910, GO: 0006955, and GO: 0002376) and Kyoto Encyclopedia of Genes and Genomes (KEGG) (B-cell receptor signaling pathway, NK cell–mediated cytotoxicity) analyses, which was consistent with increased tumor infiltration of macrophages (Fig. 3B). The gene discussed is IL33; the disease is neoplasm.
