Immunohistochemical Expression Of Cortactin, E-Cadherin, And Mdm2 Proteins In Solid Ameloblastoma Versus Odontogenic Keratocyst (An Immunohistochemical Study), Hanaa Abdel Samiaa, Nadia Radi, Eman Abo Hager, Adel Shouman
Al-Azhar Journal of Dentistry
ABSTRACT Purpose: The extent of invasion can be analyzed by the expression and production of various genes and proteins by lesional cells. However, current clinical parameters lack the potential to predict the neoplastic behavior in solid ameloblastoma (SAB) and odontogenic keratocyst (OKC). Cortactin, an F-actin binding protein, overexpression has been correlated with advanced clinic pathological stage and poor prognosis in several tumors. E-cadherin belongs to the classical cadherins which. Low E-cadherin expression correlated to aggressive, poorly differentiated, high-grade carcinomas and low patient survival. Human-murine double minute 2 (MDM2), contributes to the promotion of cell growth, survival, invasion, and therapeutic resistance, …
