| Outline of Final Research Achievements |
In the ameloblastoma cell line AM-1 cells, Sprouty 2 was found to be strongly induced upon EGF stimulation. On the other hand, when the influence of Sprouty 2 on its proliferation activity in resected sections of ameloblastoma was analyzed, the expression of Ki - 67 was suppressed in the site where Sprouty2 was strongly expressed. In addition, as an action of Sprouty 2 in the bone that is the origin of ameloblastoma, it inhibited proliferation by BMP 2 stimulation and suppressed cytokine secretion.
From the above results, it was found that EGF - induced Sprouty2 in enamel epithelioma suppresses tumor growth by controlling FGF stimulus suppressively.
