What We Do
Metabolism produces the building blocks and energy necessary for life through an elegant series of dynamically regulated biochemical transformations. Defects in metabolism arise as we age. Scientists in the Aging and Metabolism Research Program have a common interest in the metabolic basis of age-related disease and in extending the health of our aging population.
Our investigators study a variety of age-related diseases integrated across multiple organ systems, including heart failure, diabetic cardiomyopathy, macular degeneration, osteoarthritis, sarcopenia, and neurodegenerative disorders. Common among these afflictions are alterations in cellular metabolism and energy production. Mitochondria are intracellular organelles that play an essential role in metabolism and in the response of cells to physiologic and pathophysiologic stress. The laboratories that comprise our Program investigate distinct aspects of mitochondrial and cellular metabolism, identifying alterations that occur with age that are exacerbated by obesity and diabetes. Associated defects in energy homeostasis, cellular and mitochondrial quality control, production and removal of toxic free radical species, and the inflammatory response are explored to define underlying causes of diseases that primarily afflict the elderly. Together, these multidisciplinary approaches create a synergistic, collaborative, and creative environment that fosters discovery and training.
