Project description:Duchenne muscular dystrophy (DMD) is a genetic disease that results in the death of affected boys by early adulthood.The genetic defect responsible for DMD has been known for over 25 years, yet at present there is neither cure nor effective treatment for DMD. During early disease onset, the mdx mouse has been validated as an animal model for DMD and use of this model has led to valuable but incomplete insights into the disease process. For example, immune cells are thought to be responsible for a significant portion of muscle cell death in the mdx mouse; however, the role and time course of the immune response in the dystrophic process have not been well described. In this paper we constructed a simple mathematical model to investigate the role of the immune response in muscle degeneration and subsequent regeneration in the mdx mouse model of Duchenne muscular dystrophy. Our model suggests that the immune response contributes substantially to the muscle degeneration and regeneration processes. Furthermore, the analysis of the model predicts that the immune system response oscillates throughout the life of the mice, and the damaged fibers are never completely cleared.

Project description:Skeletal muscle wasting results from numerous pathological conditions impacting both the musculoskeletal and nervous systems. A unifying feature of these pathologies is the upregulation of members of the E3 ubiquitin ligase family, resulting in increased proteolytic degradation of target proteins. Despite the critical role E3 ubiquitin ligases in regulating muscle mass, the specific proteins they target for degradation and the mechanisms by which they regulate skeletal muscle homeostasis remain ill-defined. Here, using zebrafish loss of function models combined with in vivo cell biology and proteomic approaches, we identified the endoplasmic reticulum chaperone, BiP, as a novel target of the E3 ubiquitin ligase atrogin-1. A loss in atrogin-1 results in an accumulation of BiP, leading to impaired mitochondrial dynamics and a subsequent loss in muscle fibre integrity. We further implicate a disruption in atrogin-1 mediated BiP regulation in the pathogenesis of Duchenne Muscular Dystrophy. We reveal that BiP is not only upregulated in Duchenne Muscular Dystrophy, but its inhibition using pharmacological strategies, or by upregulating atrogin-1, significantly ameliorates pathology in a zebrafish model of Duchenne Muscular Dystrophy. Collectively, our data implicates a novel disease axis in the pathogenesis of Duchenne Muscular Dystrophy, and highlights atrogin-1’s essential role in maintaining muscle homeostasis.

Project description:Large animal models for Duchenne muscular dystrophy (DMD) are indispensible for preclinical evaluation of novel diagnostic procedures and treatment strategies. To evaluate functional consequences of Duchenne muscular dystrophy (DMD) in skeletal muscle and myocardium, we used a new genetically engineered dystrophin KO pig model displaying hallmarks of human DMD. Heart and skeletal muscle tissue samples of DMD pigs and wild-type (WT) controls at three different ages were analyzed by label-free proteomics.

Project description:Eosinophils are implicated in the development of many chronic diseases. However, their function in muscular dystrophy is understudied. Here we demonstrate that muscle hyper-eosinophilia could be a marker of poor outcomes in Duchenne Muscular Dystrophy.

Project description:Canine muscular dystrophy (CXMDJ) is a dog model of the lethal X-linked muscle disorder Duchenne muscular dystrophy (DMD), which is caused by loss of dystrophin. Gene expression profile was analyzed in the diaphragm muscles of normal Beagle dogs and CXMDJ before and 1 hour after initial respiration.

Project description:Duchenne muscular dystrophy (DMD) is caused by genetic deficiency of dystrophin and characterized by massive structural and functional changes of skeletal muscle tissue, leading to terminal muscle failure. In this project, proteomics data from skeletal muscle of a genetically engineered DMD pig model were investigated in order to confirm muscular fibrosis and MSOT signals.

Project description:Summary: Genetic disorders of muscle cause muscular dystrophy, and are some of the most common inborn errors of metabolism. Muscle also rapidly remodels in response to training and innervation. Muscle weakness and wasting is important in such conditions as aging, critical care medicine, space flight, and diabetes. Finally, muscle can also be used to investigate systemic defects, and the compensatory mechansisms invoked by cells to overcome biochemical and genetic abnormalities. Here, we provide a 13 group data set for comparative profiling of human skeletal muscle. Groups studied are: Normal human skeletal muscle, Acute quadriplegic myopathy (AQM; critical care myopathy), Juvenile dermatomyositis (JDM), Amyotophic lateral sclerosis (ALS), spastic paraplegia (SPG4; spastin), Fascioscapulohumeral muscular dystrophy (FSHD), Emery Dreifuss muscular dystrophy (both X linked recessive emerin form; autosomal dominant Lamin A/C form), Becker muscular dystrophy (partial loss of dystrophin), Duchenne muscular dystrophy (complete loss of dystrophin), Calpain 3 (LGMD2A), dysferlin (LGMD2B), FKRP (glycosylation defect; homozygous for a missense mutation). U133A and U133B microarrays are both available. Hypothesis: This data set is able to define biochemical pathways that are either specific for a disease group, or shared between disease groups. For example, this data set has been used to determine the biochemical pathway perturbations that are shared between the two different types of Emery Dreifuss muscular dystrophy (lamin A/C, and emerin). Specific Aim: The specific aim of this study is to determine the disease-specific transcriptional profiles of these 13 patient groups, and to determine if these expression fingerprints provide either pathophysiology or diagnostic information for these diseases. Some of the groups in this large data set have been reported previously using U95A microarrays, as follows: Juvenile dermatomyositis (JDM): Tezak Z, Hoffman EP, Lutz JL, Fedczyna TO, Stephan D, Bremer EG, Krasnoselska-Riz I, Kumar A, Pachman LM.
