摘要: Epidermal growth factor receptor (EGFR) is a member of the HER family tyrosine kinase cell-surface receptors that are dysregulated in many types tumor; its expression has been associated with poor prognosis colon cancer.1 There at least two opportunities to interfere EGFR signaling being exploited clinically.2 In one approach, extracellular domain bound by antibodies, such as cetuximab, block ligand-mediated dimerization and subsequent activation receptor. second, drugs inhibit phosphorylation, gefitinib erlotinib. Irinotecan topoisomerase . . .
