Abstract:
Objective To study the relationship between EZH2 and Ki-67 expression and both in ameloblastoma and normal oral mucosa.Methods EZH2 and Ki-67 were detected by immunohistochemical SP method in 50 cases of ameloblastoma (30 cases primary,20 cases recurrence) and expression in 20 cases of normal oral mucosa.Results The positive expression of EZH2 protein in recurrent ameloblastoma was (36.25±7.24) %,significantly higher than that of primary ameloblastomas (25.26±4.28) % (P < 0.001).Ki-67 in recurrent positive expression in ameloblastoma was (34.96±5.28) %,significantly higher than that of primary ameloblastomas (29.68±3.27) % (P < 0.05).There was positively corTelated on EZH2 and Ki-67 (P < 0.05),but not on the size of tumor and gender (P > 0.05).Conclusions There are high expression of EZH2 and Ki-67 in ameloblastoma,and their play key role in the occurrence and development of ameloblastoma.They can be used as a reference index for the prognosis.The combined detection of EZH2 and Ki-67 protein expression with clinical evidence and its prognosis may contribute to the process of ameloblastoma and recurrence.
