Project description:Duchenne muscular dystrophy (DMD) is a classical monogenic disorder, a model disease for genomic studies and a priority candidate for regenerative medicine and gene therapy. Although the genetic cause of DMD is well known, the molecular pathogenesis of disease and the response to therapy are incompletely understood. Here, we describe analyses of protein, mRNA and microRNA expression in the tibialis anterior of the mdx mouse model of DMD. Notably, 3272 proteins were quantifiable and 525 identified as differentially expressed in mdx muscle (P < 0.01). Therapeutic restoration of dystrophin by exon skipping induced widespread shifts in protein and mRNA expression towards wild-type expression levels, whereas the miRNome was largely unaffected. Comparison analyses between datasets showed that protein and mRNA ratios were only weakly correlated (r = 0.405), and identified a multitude of differentially affected cellular pathways, upstream regulators and predicted miRNA–target interactions. This study provides fundamental new insights into gene expression and regulation in dystrophic muscle. 3 Wt, 4 mdx and 4 Pip6e-PMO treated mdx mice

Project description:Absence of dystrophin protein causes cardiac dysfunction in patients with Duchenne muscular dystrophy (DMD). Unlike boys with DMD, the common mouse model of DMD (B10-mdx) does not manifest cardiac deficits until late adulthood. This has limited our understanding of the mechanism and therapeutic approaches to target the pediatric onset of cardiac pathology in DMD. Here we show that the mdx mouse model on the DBA/2J genetic background (D2-mdx) displays juvenile-onset cardiac degeneration. Molecular and histological analysis revealed that cardiac damage in this model is linked to increased leukocyte chemotactic signaling and an inability to resolve inflammation. These deficiencies result in chronic inflammation and fibrotic conversion of the extracellular matrix (ECM) in the juvenile D2-mdx heart. To address these pathologies, we tested the utility of pro-resolution therapy to clear chronic cardiac inflammation. Use of an N-formyl peptide receptor (FPR) agonist helped physiologically resolve inflammation and mitigate the downstream events that lead to fibrotic degeneration of cardiomyocytes, preventing juvenile onset cardiac muscle loss. These results establish the utility of D2-mdx model to study events associated with pediatric-onset cardiac damage and demonstrates pro-resolution therapy as an alternate to anti-inflammatory therapy for treating degenerative cardiac pathology that leads to cardiomyopathy in DMD.

Project description:Humanized 3D-tissue-engineered-skeletal-muscles (3D-TESMs) offer advanced disease modelling, but their application often require isogenic controls and involves laborious and time consuming methodology. Here, by combining 3D-TESM and shRNA approaches, we developed a “one-line-fits-all” disease modelling strategy to rapidly induce distinct genetic deficiencies in a single hiPSC-derived cell line. As proof-of-principle, we recapitulated disease-associated pathology of Duchenne Muscular Dystrophy and LGMD2A caused by loss of function of DMD and CAPN3, respectively. shRNA-mediated knockdown of DMD or CAPN3 induced a loss of contractile function, disruption of tissue architecture, and disease-specific proteomes within a seven days period. Pathology in DMD 3D-TESMs was partially rescued by a candidate gene therapy treatment using microdystrophin, with similar efficacy compared to mouse models. These results show that isogenic shRNA-based humanized 3D-TESM models provide a fast and efficient tool to model muscular dystrophies and are useful for the preclinical evaluation of novel therapies.

Project description:Induced pluripotent stem (iPS) cells can be generated from somatic cells by transduction with several transcription factors in both mouse and human. However, direct reprogramming in other species has not been reported. Here, we established an efficient method to generate monkey iPS cells from fibroblasts by retrovirus-mediated introduction of the four monkey transcription factors OCT4 (POU5F1), SOX2, KLF4, and c-MYC. The monkey iPS cells displayed ES-like morphology, expressed ES cell-marker genes, shared similar global gene profiles and methylation status in the OCT4 promoter to those of monkey ES cells, and possessed the ability to differentiate into three germ layers in vitro and in vivo. Our results suggest that the mechanism of direct reprogramming is conserved among species. The efficient generation of monkey iPS cells will allow investigation of the feasibility of therapeutic cloning in primate model with various diseases. Keywords: Induced pluripotent stem, iPS, Rhesus monkey We analysed each sample (Rhesus monkey fibroblast, embryonic stem cell (ES) and induced pluripotent stem cell (iPS)) for three replications and sought to see high similarty between iPS and ES.

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 treated by somatic gene editing are shown.
