Abstract
Ameloblastomas are defined as aggressive neoplasms arising from the odontogenic epithelium which exhibit a locally invasive behavior with a high rate of recurrence. If left untreated, they often lead to extensive tissue destruction and deformity. Due to the fact that these tumors emerge from remnants of normal odontogenic apparatus, which is strictly regulated through several genes, studies have been done in an attempt to unravel the relation between these two processes. The normal genetic regulation takes place through different signaling pathways, including four major families: TGF [Transforming Growth Factors, which include BMPs (Bone Morphogenetic Proteins)], FGF (Fibroblast Growth Factors), Hh (Hedgehogs) and Wnt (Wingless). Each family consists of several signals encoded by different genes. The unraveling of specific details concerning these genes and the mechanisms whereby the expression and relationships among them are mediated, may provide an opportunity to develop new treatment therapies and afford efficient prevention.
Key words: Ameloblastoma, sonic hedgehog, bone morphogenetic protein, fibroblast growth factor, wingless.
