Relationship between epidermal growth factor receptor and the correlated-signal proteins in nasopharyngeal carcinoma and its effects on cell proliferation
Objective To investigate the relationship of epidermal growth factor receptor(EGFR) expression with phosphorylated extracellular-signal regulated protein kinase(p-ERK),c-fos,Ki-67 signal proteins in nasopharyngeal cancer(NPC) and nasopharyngeal mucosal epithelia,and study the effect of Cetuximab(monoclonal antibody against EGFR) on the proliferation of NPC CNE-2Z cells.Methods Immunocytochemical SP method was adopted to detect the expression of EGFR,p-ERK,c-fos and Ki-67 protein in NPC cells from 30 patient...
