Abstract: Objective: To detect the expression and clinical significance of N-α-acetyltransferase10 protein (Naa10p) and cellular prion protein (PrPc) in oral squamous cell carcinoma (OSCC), oral leukoplakia and normal oral mucosa. Methods: The expressions of Naa10p and PrPc were detected by immunohistochemistry assay (EnvisionTM) in OSCC (112 cases), leukoplakia (42 cases) and normal mucosa tissues (11 cases), and the correlation between their expression and clinical features was analyzed. Results: The expression level of Naa10p and PrPc was the highest in OSCC, followed by leukoplakia, and the lowest in normal mucosa tissues. Naa10p expression in three different tissues was statistically significant (P<0.05). PrPc expression was significantly different in OSCC compared to oral leukoplakia and normal tissues (P<0.05), while there was no difference between oral leukoplakia and normal mucosa. In addition, Naa10p expression was correlated with TNM stage, lymph node metastasis and cell differentiation of patients with OSCC (P<0.05), but was not associated with gender and age. Moreover, PrPc expression was only positively correlated with cell differentiation in OSCC (P<0.05), while Naa10p expression was negatively correlated with cell differentiation (P<0.05). Conclusion: Naa10p and PrPc are associated with the tumorgenesis and metastasis of OSCC.
