The Translational Machinery As A Target For Radiosensitization, Thomas John Hayman

USF Tampa Graduate Theses and Dissertations

Current approaches aimed at improving the efficacy of radiation as a cancer treatment modality involve the development and application of molecularly targeted radiosensitizers, a strategy that requires a thorough understanding of the fundamental processes comprising the cellular radioresponse. Recent data indicating that radiation modifies gene expression primarily through translational control rather than transcriptional events suggests that mRNA translation contributes to cell survival after irradiation. The overall goal of this project is to determine whether the regulatory/rate-limiting components of the translational machinery provide targets for tumor cell radiosensitization. The majority of translation in mammalian cells occurs in a cap-dependent manner and …
