OverviewAI-generated summary
Megan E. Rosa‐Caldwell's research focuses on understanding the physiological changes in skeletal muscle, particularly in the context of disease states such as cancer cachexia and disuse atrophy. Her work investigates the molecular and cellular mechanisms underlying muscle weakness and atrophy, with a specific interest in sex-based differences in these responses.
Recent publications from her laboratory have explored how mitochondrial stress contributes to muscle weakness during cancer cachexia. Additionally, her research has examined the differential impact of disuse atrophy on male and female mice, noting variations in catabolic signaling and mitochondrial aberrations. Her work also includes a systematic review on anorexia nervosa and its effects on muscle health. Rosa‐Caldwell collaborates with several researchers at the University of Arkansas at Fayetteville, including Tyrone A. Washington, Eleanor R. Schrems, Nicholas P. Greene, and Francielly Morena da Silva, with whom she has co-authored numerous publications.
With a career h-index of 21 and over 1,500 citations from more than 100 publications, Rosa‐Caldwell is recognized as a highly cited researcher. Her active laboratory website indicates ongoing research activities.
