Biological Indicators of Racial Disparity in Ameloblastoma Recurrence
Project Summary Ameloblastoma accounts for 14% of all odontogenic tumors and African-Americans are five times more likely to develop ameloblastoma compared to Caucasians. Despite radical surgery, 10% of ameloblastomas recur and 25% of recurrent ameloblastomas occur in the black racial group. The biological determinants of ameloblastoma racial disparity are unclear and there are no specific biological markers to predict recurrence. Most ameloblastomas display genetic mutations of BRAF that encodes the serine/threonine protein kinase B-Raf, an activator of MAPK/ERK-signaling pathway. BRAF oncogenes induce the expression of key autophagic markers that include LC3, p62 and BECLIN1. High…
