Abstract

Abstract: PURPOSE:To detect the expression of hypoxia-inducible factor 1α in ameloblastoma and to determine if it was involved in the recurrence of ameloblastoma. METHODS: Five pairs of ameloblastoma and normal para-tissue were used for transcriptional group sequence; 120 formalin-fixed, paraffin-embeded tissue blocks of ameloblastoma specimens were compared at protein level using immunohistochemistry for HIF-1α staining. The data were analyzed with SAS 9.3 software package. RESULTS: The transcriptional level of HIF-1α and its related molecules in 3/5 specimens were changing consistently and obviously after sequencing; the HIF-1α and slug expression levels were significantly higher in recurrent ameloblastoma. About 40% of recurrent ameloblastoma had higher HIF-1α staining than primary ameloblastoma and 48.33% of recurrent ameloblastoma had higher slug staining than primary ameloblastoma (P<0.05). CONCLUSIONS: Higher expression of HIF-1α plays an important role in the recurrence of ameloblastoma.
