In many other studies, other pathways (such as endothelial cell-specific molecule-1, 5′-ecto-nucleotidase, tissue inhibitor of metalloproteinase-3, epidermal growth factor receptor (EGFR), insulin-like growth factor receptor, and phosphatidylinositol 3-kinase signalling) and genes (metastatic-suppressor genes, that is, KISS1 metastasis-suppressor, CD82, NME/NM23 nucleoside diphosphate kinase 1) [12] have been described as implicated in tumour dormancy process. The gene discussed is EGFR; the disease is neoplasm.
