摘要: SummaryEpidermal growth factor receptor (EGFR) is a transmembrane protein with tyrosine kinase activity. The has cysteine-rich sequence repeats in its extracellular ligand-binding domains. Elevated levels of EGFR are associated malignant transformation squamous cells and observed cell carcinomas from the lung, head, neck, skin, cervix esophagus. We examined expression laryngeal carcinoma (SCC) (N = 24) non-neoplastic polyps 7) using streptavidin-biotin immunohistochemistry monoclonal antibody (Serotec: MCA-571) to protein. were classified as well differentiated 2), moderately 16) poorly 6). Tissues metastatic tumor deposits lymph nodes 5) also studied. Overexpression was present, form strong cytoplasmic immunostaining, majority SCC cases (n 20; 83%) all deposits. I...
