Theses and Dissertations
A targeted approach to the development of antifolate therapies has been sought for many years. Central to the success of such development is an understanding of the molecular mechanisms dictating the sensitivity of cells to antifolates and the fundamental differences of these processes between normal and neoplastic phenotypes. This dissertation addressed transcriptional mechanisms and cell-signaling events responsible for the efficacy of antifolate therapies. Transcriptional processes and cell signaling pathways are often aberrant in neoplastic tissues, providing a potential point of distinction between a normal and neoplastic cellular state. Folylpolyglutamate synthetase (FPGS) catalyzes the formation of poly-γ-glutamate derivatives of folates and …
