- Abnormal expression of Notch1 protein was often found in many kinds of primary tumors, but its correlation with nasopharyngeal carcinoma (NPC) is still unclear. This study was designed to investigate the expression of Notch1 and its downstream proteins P21(WAF1) and Involucrin in NPC, and analyze their correlations with the differentiation of NPC cells. The expression of Notch1, P21(WAF1), and Involucrin in 101 specimens of NPC and 20 specimens of chronic inflammatory nasopharyngeal mucosa were detected by SP immunohistochemistry. The positive rates of Notch1, P21(WAF1), and Involucrin were 100%, 90.0%, and 100% in chronic inflammatory nasopharyngeal mucosa, and were 77.2%, 89.1%, and 80.1% in NPC, respectively. The expression of Notch1, P21(WAF1), and Involucrin were significantly suppressed along with descending differentiation of NPC (P=0.000, P=0.026, and P=0.000). The positive rates of Notch1, P21(WAF1), and Involucrin were significantly higher in keratinizing squamous cell carcinoma (KSCC) than in diffe
