The exact pathogenesis of ameloblastoma is not fully understood. It is thought that ameloblastoma is the result of either suppression of matrix metalloproteinase-2 that may inhibit the local invasiveness of ameloblastoma, or there is also some research suggesting that α5β1 integrin may participate in the local invasiveness of ameloblastomas.
There are no established causes for ameloblastoma. It is thought that ameloblastoma may be the result of either decreased expression of [[matrix]] metalloproteinase-2 which helps in inhibition of the local invasiveness of ameloblastoma, or it is may be due to increased expression of  α5β1 [[integrin]] which participate in the local invasiveness of ameloblastoma.

There is evidence that suppression of matrix metalloproteinase-2 may inhibit the local invasiveness of ameloblastoma, however, this was only demonstrated in vitro. There is also some research suggesting that α5β1 integrin may participate in the local invasiveness of ameloblastomas. A recent study discovered a high frequency of ''BRAF V600E'' mutations in solid/multicystic ameloblastoma. These data suggests drugs targeting mutant ''BRAF'' as potential novel therapies for ameloblastoma.

Overview

There are no established causes for ameloblastoma. It is thought that ameloblastoma may be the result of either decreased expression of matrix metalloproteinase-2 which helps in inhibition of the local invasiveness of ameloblastoma, or it is may be due to increased expression of α5β1 integrin which participate in the local invasiveness of ameloblastoma.

Genetic Causes

  • Ameloblastoma is caused by a mutation in the FGFR2-RAS-BRAF V600E gene.[3][4]
