Electronic Theses and Dissertations
This dissertation is an analysis of skeletal muscle atrophy and a molecular assessment of potential preventative treatments. Chapter I begins with a background of skeletal muscle atrophy along with an analysis of associated molecular pathways. Here, we discuss how skeletal muscle atrophy is the consequence of protein degradation exceeding protein synthesis and can occur when a muscle is abnormally disused. The development of therapies prior to skeletal muscle atrophy settings to diminish protein degradation is scarce and could be useful to prevent negative clinical outcomes of patients who must unload and disuse musculature over extended periods. Mitochondrial dysfunction is associated …

Doxorubicin (DOX) is an effective chemotherapeutic treatment with lasting deleterious side effects in heart and skeletal muscle. As an increased percentage of patients live many years past their cancer treatments, addressing the long-term side effects of chemotherapy treatment becomes critical. In an attempt to prevent heart and skeletal muscle damage caused by DOX, two co-treatments, exercise (EX) or metformin (MET) were studied for their effectiveness in maintaining muscle function, mitochondrial respiration and iron regulation. DOX is known to bind with iron, contributing to oxidative damage resulting in cardiac and skeletal muscle toxicity. However, the degree to which the toxic side …
