Photo-potentiation of cisplatin chemotherapy

摘要

Methods disclosed herein capitalize on the discovery that DNA Structure Specific Recognition Proteins (SSRPs) can be induced to bind covalently to genomic lesions formed by chemotherapeutic agents, particularly cisplatin-type agents, by photo-irradiation with ultraviolet light. Methods and compositions based on this discovery are provided for sensitizing particular eukaryotic cells to killing by chemotherapeutic agents, particularly cisplatin-type drugs. Methods and compositions also are provided for potentiating cytotoxicity of a chemotherapeutic agent, particularly a cisplatin-type agent.
