CHS Researcher Profiles
Charlotte A. Peterson, Ph.D.
Joseph Hamburg Endowed Professor
CHS Associate Dean for Research
Dr. Peterson's research focuses on elucidation of cellular and molecular mechanisms controlling skeletal muscle structure and function. She is currently funded to study stem cell activity during muscle regeneration and has provided evidence that inherent changes in gene expression in stem cells responsible for muscle repair occur with age so that the cells display an adipocyte- or fat-like phenotype, suggesting that common mechanisms may contribute to loss of bone and muscle with age.
In a related project, she is also studying the effects of obesity on muscle stem cell activity. Dr. Peterson also studies the genetic basis of differences in the muscle inflammatory response to damage. The inflammatory cytokine interleukin-1 (IL-1) is being studied to determine if IL-1 gene polymorphisms and the IL-1-mediated inflammatory response to damaging exercise are predictive of the hypertrophic response of muscle to chronic resistance training by elderly individuals.
Finally, ongoing studies are identifying mechanisms contributing to restoration of muscle mass following atrophy due to disuse. Her work emphasizes changes that occur with age with the long term goal of preventing frailty and loss of functional independence.
