1-in-3 persons with type 2 diabetes (T2DM) develop chronic kidney disease (CKD), which is characterized by progressive renal dysfunction leading to end-stage renal disease. In response to elevated blood glucose and systemic inflammation of diabetes, a process of active thickening of the renal glomerular basement membrane ensues with concomitant damage to the structural supports (podocytes) of the kidneyճ filtration barrier. This results in impaired renal filtration. The metabolic sequelea of T2DM and CKD also, synergistically, alter skeletal muscleճ degradative pathways, satellite cell function (muscle reparative cells), and mitochondrial health (muscle energetic machinery) -- resulting in muscle breakdown, poor muscle quality, …

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 …
