Abstract
|
|
|
|
High-grade mucoepidermoid carcinomas (MECs) have difficulty in cure and 5-year survival rate is quiet low. Therefore, we need new therapeutic agents and molecular targets. Betulinic acid (BA) is one of the materials which is easily found in the world and shows tumor-suppress effects in various tumor types. In addition, many kinds of normal tissues have a resistance to BA treatment. In this study, we investigated the anti-proliferative activity of BA and its molecular targets in MC-3 human MEC cells using western blot analysis and DAPI staining. BA inhibited cell viability and induced apoptosis in MC-3 cells. It affected Specificity protein 1 (Sp1) and its downstream molecule, survivin whereas it did not affect myeloid cell leukemia-1 (Mcl-1). Therefore, we suggest that BA can be a potential anti-cancer drug candidate regulating Sp 1 and survivin to exert apoptotic cell death.
