In vivo and in vitro study of co-expression of LMP1 and Cripto-1 in nasopharyngeal carcinoma

Nasopharyngeal carcinoma, an epithelial-derived malignant tumor which because of its anatomical location and atypical early symptoms, when diagnosed invasion and metastasis often have occurred. This requires a better understanding of the development mechanism, identifying diagnostic markers, and dev...

description Nasopharyngeal carcinoma, an epithelial-derived malignant tumor which because of its anatomical location and atypical early symptoms, when diagnosed invasion and metastasis often have occurred. This requires a better understanding of the development mechanism, identifying diagnostic markers, and developing new treatment strategies. To study the relationship of LMP1 and Cripto-1 in nasopharyngeal carcinoma. The expression of LMP1 and Cripto-1 in specimens obtained from nasopharyngeal carcinoma patients (n=42) and nasopharyngitis patients (n=22) were examined. The expression of LMP1 and Cripto-1 in LMP1-negative and LMP1-positive (CNE1-LMP1) cells were also examined. The expression of LMP1 and Cripto-1 was significantly higher in nasopharyngeal carcinoma than in nasopharyngitis (p
