Abstract:

OBJECTIVE: This study aimed to analyze the expression,clinical significance of epithelial membrane protein-1(EMP1) in nasopharyngeal carcinoma. METHODS:Immunohistochemistry and western blot were used to analyze EMP1 protein expression in 75 cases of nasopharyngeal carcinoma and normal tissues to study the relationship between EMP1 expression and clinical factors. RESULTS:Immunohistochemistry:The level of EMP1 protein expression was found to be significantly lower in nasopharyngeal carcinoma tissue than normal tissues (P<0.05). Western blot:The relative amount of EMP1 protein in nasopharyngeal carcinoma tissue was found to be significantly lower than in normal tissues (P<0.05). The level of EMP1 protein expression  correlated with lymph node metastasis,clinical stage and histological grades (P<0.05). CONCLUSION:Decreased expression of EMP1 may play important roles in the pathogenesis and progression of nasopharyngeal carcinoma.
