Tristan Wold Owens, PhD

Dr. Owens [Suzanne and Bob Wright Fellow] focuses on heat shock proteins (HSPs) and their “master regulator” called heat shock transcription factor 1 (HSF1). The transformation and growth of cancers causes a wide array of cellular stresses including metabolic changes, genomic instability, and protein misfolding that would halt the growth of a normal cell. Tumor cells, however, depend on cellular stress response machinery, like HSPs, for their survival. HSF1 is critical to tumor development and progression, and HSF1 activity is strongly correlated with poor prognosis in many common cancers. For decades, efforts to develop cancer therapies targeting HSPs have failed. Dr. Owens aims to understand how HSPs and HSF1 interact to regulate activity, and how this regulation is co-opted to promote tumor growth and progression.
