ERBB2 and cancer: Topology analysis yields core key targets, such as TP53, INS, IL6, VEGFA, MYC, CASP3, ESR1, EGF, CCND1, PPARG, ERBB2, NFKBIA, TLR4, RELA, and CASP8, and the results of KEGG enrichment analysis showed that JSQS mainly works through pathways in cancer, phosphatidylinositol-3-kinaseRAC–serine/threonine-protein kinase signaling, and mitogen-activated protein kinase (MAPK) signaling pathway, and aryl hydrocarbon receptor nuclear translocator signaling pathway.
