Project Title:Integrated in vivo quantitative proteomics and nutrient tracing reveals age-related metabolic rewiring of pancreatic beta cell function
Project Summary:Aging is associated with fundamental changes in pancreatic β-cell physiology; yet, the mechanisms that drive these age-related changes are poorly understood. Here, we performed comprehensive in vivo quantitative proteomic profiling of pancreatic islets from adolescent and old mice. Nutrient tracing and targeted metabolomics demonstrated accelerated accumulation of glucose-derived metabolites and coupling factors in aged islets, indicating that age-related changes in glucose metabolism contribute to improved glucose-stimulated insulin secretion with age. Together, our study provides the first in-depth characterization of age-related changes in the islet proteome and establishes metabolic rewiring as an important mechanism for age-associated changes in β-cell function.
