"The Sontag Foundation Distinguished Scientist Award was instrumental to my success as a scientist. The Sontag Foundation recognized my potential very early in my career, at a time when our science was in a fledgling state, and I was an unproven independent scientist. Their investment supported my laboratory to develop novel scientific methodologies that have become a mainstay of our research. I am grateful for their continued engagement as it pushes us to produce cutting-edge science."

About DSA-Funded Research

High-grade gliomas are highly aggressive tumors that are associated with a very poor prognosis. Current therapeutic approaches are largely palliative and novel therapies that could extend disease free intervals or survival times are desperately required. Interestingly, intracellular lipid or "fat" metabolism has emerged as an important regulator of cancer growth and behavior. We have discovered that inactivating a key component of lipid metabolism, the SREBP proteins, markedly decreases human glioma growth. In-depth mechanistic studies in the laboratory revealed that SREBP influences multiple aspects of brain tumor cell biology, including sugar and fat metabolism, proliferation and survival. In combination, these studies argue that SREBP could be a compelling therapeutic target in brain cancer. However, many more studies need to be done so that we can better understand the impact of SREBP activity in brain cancer. In this application, we propose three aims designed to expand on our knowledge of how the SREBP-driven metabolic program of brain cancer is controlled, and to determine the functional consequences of SREBP activity on chemo-therapeutic resistance. These studies explore a poorly understood aspect of brain cancer biology, and will help to determine if targeting the SREBP pathway is a viable therapeutic approach for the treatment of brain cancer.
