Scott Oakes’s laboratory studies how mammalian cells commit “suicide” in response to various forms of damage and what goes wrong with this process in cancer and other diseases. In particular, they focus on a type of stress that occurs when the cell’s protein folding factory—an organelle called the endoplasmic reticulum—is overwhelmed and protein quality control fails. He is actively engaged in developing drugs to control cell fate under these conditions, which have potential to benefit patients with diseases from cancer to neurodegeneration.

Lori Sussel is the Director of Basic and Translational Research at the Barbara Davis Center for Diabetes. The main focus of the Sussel lab is to understand the complex transcriptional networks that regulate development, differentiation and function of the pancreas. Our early studies led to the ground-breaking discovery that a ghrelin-producing “epsilon” cell population normally resides in the fetal islet, and that a close lineage relationship exists between the islet beta and epsilon cell populations. We went on to identify several novel regulatory pathways that are essential for islet lineage specification, normal pancreas development and the maintenance of beta cell maturation.

Dr. Sarah Tersey is an islet biologist whose research focuses on the role of the ß-cell in the development of type 1 and type 2 diabetes. The primary goal of her research focuses on understanding the molecular pathways that play a role in the development of diabetes. Specifically, pathways that include the enzymes 12-lipoxygnease and deoxyhypusine synthase. By using inhibitors against these pathways or creating genetic deletions of either of these genes, Dr. Tersey has shown that diabetes can be prevented. A second major focus of my research is the development of biomarkers that will best predict the likelihood of any one individual’s risk to develop type 1 diabetes. Within this concept, she demonstrated that the dysfunction of the pancreatic islet precedes the onset of type 1 diabetes. This research has changed the standard dogma of the islet as a silent bystander to the immune system, to the new way of thinking – that the pancreatic islet is a major player in its own demise during the pre-course of type 1 diabetes.
