Jarrah2014 - mathematical model of the immune response in muscle degeneration and subsequent regeneration in Duchenne muscular dystrophy in mdx mice

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.

Atrogin-1 regulates BiP levels - novel therapeutic targets for Duchenne Muscular Dystrophy

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.

Elevated numbers of infiltrating eosinophils accelerate the progression of Duchenne Muscular Dystrophy pathology in mdx mice.

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.

A scalable, clinically severe pig model for Duchenne muscular dystrophy

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.

Muscle H3K27ac landscape remodeling with glucocorticoid steroid regimens

Project description:Duchenne muscular dystrophy is caused by genetic defects in the gene encoding dystrophin and leads to progressive muscle degeneration. Glucocorticoid steroids are current mainstay pharmacological regimen to decrease muscle inflammation and prolong the ambulatory period in these patients, but daily intake of glucocorticoids like prednisone and deflazacort causes adverse side effects like osteoporosis, adrenal suppression, insulin resistance and obesity. Intermittent steroid dosing has been proposed as alternative to maintain benefits and limit side effects, but a detailed understanding of the mechanisms underpinning the regimen-specific effects in muscle is still missing. Here we explore how once-daily versus once-weekly prednisone (4 week-long treatment) affect the epigenomic landscape in mdx mouse muscle (genetic model of Duchenne muscular dystrophy; DBA/2J background) through H3K27 acetylation profiles.
