Project title: Disruption of mitochondrial function in pancreatic beta-cells
Project description: Mitochondrial dysfunction is thought to be contributing factor to the growing epidemic of diabetes. Our lab specializes in transcriptional regulation of mitochondrial function and recently created a new mouse model to investigate how pre-existing defects in mitochondrial metabolism impact beta-cell biology and the pathogenesis of diabetes. Using the cre/LoxP system, we generated a beta-cell specific knock-out of a key transcriptional regulator of mitochondrial biogenesis and function. We have characterized the metabolic phenotype of these mice and find they have significant alterations in glucose homeostasis, beta-cell survival, and insulin secretion in vivo.
The project involves investigating how our genetic knock-out model specifically impacts beta-cell survival and function in vitro. Specifically, the applicant will help to determine whether mitochondrial mass and function is decreased in immortalized and primary cell cultures using fluorescent mitochondrial markers and quantitative microscopy. This will involve working with animal models, culture of cells, treatment of cells, and quantification of mass and function using state-of-the-art scanning microscopy.
