Hemangioma is a type of tumor commonly found in infants that is characterized by heavy vascularization and a disfiguring appearance. Hemangioma, though benign, can sometimes proliferate and be threatening to infants. Current treatments for infantile hemangioma include surgical removal as well as the use of topical and oral medication. However, current therapies are often ineffective at treating lesions and are commonly accompanied by dangerous side effects, creating the need for a new, safer treatment. This study targets the Yes-Associated Protein-1 (YAP-1), which has been described as an oncogene, by use of an interfering RNA technique in attempts to mediate tumor growth and progression. Western blotting of treatment and control BEND3 murine cells reveals that YAP-1 is knocked-down in treatment groups which have been infected with shYAP-1 siRNA genes. By successfully knocking down the YAP-1 protein, the potential for developing a novel targeted therapy for infantile hemangioma has been established.
