Duchenne muscular dystrophy (DMD) is an X-linked recessive neuromuscular disease that is the result of a loss of functional dystrophin, which causes cardiomyocyte fibrosis and death, leading to cardiomyopathy. In this thesis, I have utilized dynamic contrast-enhanced computed tomography (DCE-CT), positron emission tomography-fluorodeoxyglucose (PET-FDG), echocardiography, and traditional histology to longitudinally assess disease progression and degree of cardiomyopathy in a murine model of DMD (mdx:utrn-/-). No significant changes were observed in the blood flow, blood volume, or cardiac volume measured via DCE-CT, nor in standard uptake value (SUV) of glucose as measured by PET-FDG in the left myocardium between and within …

Doxorubicin (DOX) is the antineoplastic drug of preference used to treat a wide variety of malignancies, with high survival rates among treated patients. However, the benefits of this drug have become less appealing due to the side effects that occur such as DOX-induced cardiomyopathy (DIC) and an increased risk of myocardial infarction (MI). Therefore, there is an urgent need to explore the therapeutic options to treat DIC. In this context, adult stem cells have been used as a source to reduce cardiomyocyte apoptosis in DIC; however, the effects of transplanted embryonic stem (ES) cells and induced pluripotent stem (iPS) cells …
