(Submitter supplied) ABSTRACT Stimulating the commitment of implanted dystrophin+ muscle derived stem cells (MDSC) into myogenic, as opposed to lipofibrogenic, lineages is a promising therapeutic strategy for Duchenne muscular dystrophy (DMD). To examine whether counteracting myostatin, a negative regulator of muscle mass and a pro-lipofibrotic factor, would help this process, we compared the in vitro myogenic and fibrogenic capacity of MDSC from wild type (WT), myostatin knockout (Mst KO), and mdx (DMD model) (mdx) young mice under various modulators, the expression of key stem cell and myogenic genes, and the capacity of these MDSC to repair the injured gastrocnemius in aged mdx mice with exacerbated lipofibrosis. more...

(Submitter supplied) We profiled gene expression of purified cell types isolated from 5 musculoskeletal tissues: tendon, bone, muscle, cartilage and ligament. We then performed WGCNA to identify tissue-specific transcription factors, signaling pathways and cell surface receptors. The sequencing data for muscle cells is made available here.

(Submitter supplied) Duchenne muscular dystrophy (DMD) is an X-linked progressive muscle disorder resulting in muscle weakness and cardiomyopathy. MicroRNAs have shown to play a significant role in muscle development, metabolism, and disease pathologies. We demonstrated that miR-486 expression is reduced in DMD muscles and its expression levels correlate with dystrophic disease severity. miR-486 knockout mice developed disrupted myofiber architecture, decreased myofiber size, decreased locomotor activity, increased fibrosis, and metabolic defects that were exacerbated on the dystrophic mdx5cv background. more...

(Submitter supplied) Identifying microRNA target transcripts is critical in understanding their role in modulation of disease pathology through cellular processes. Here, we used isolated 6 month mouse tibialis anterior (TA) muscle tissue for RNA extraction and sequencing in order to identify mRNA transcripts overexpressed in miR-486 knockout mice compared to wildtype.

(Submitter supplied) Many common human mesenchymal tumors, including gastrointestinal stromal tumor (GIST), rhabdomyosarcoma (RMS), and leiomyosarcoma (LMS), feature myogenic differentiation. Here we report that intragenic deletion of the dystrophin-encoding and muscular dystrophy-associated DMD gene is a frequent mechanism by which myogenic tumors progress to high-grade, lethal sarcomas. Dystrophin is expressed in nonneoplastic and benign counterparts for GIST, RMS and LMS, and the DMD deletions inactivate larger dystrophin isoforms, including 427kDa dystrophin, while preserving expression of an essential 71kDa isoform. more...

(Submitter supplied) We have developed a method to generate muscle stem cells from pluripotent stem cells via teratoma formation. We further find these cells are functionally expandable in vitro while retaining their in vivo regenerative potential. The goal of this study is to compare the transcriptome of fresh and expanded teratoma-derived myogenic cells versus satellite cells.

(Submitter supplied) Muscle wasting in Duchenne Muscular Dystrophy is caused by myofiber fragility and poor regeneration that leads to chronic inflammation and muscle replacement by fibrofatty tissue. Our recent findings demonstrated that Resolvins, a class bioactive lipids derived from omega-3 fatty acids, have the capacity to dampen inflammation and stimulate muscle regeneration to alleviate disease progression. This therapeutic avenue has many advantages compared to glucocorticoids, the current gold-standard treatment for Duchenne Muscular Dystrophy. more...

(Submitter supplied) RNA-binding proteins (RBPs) are essential for skeletal muscle regeneration and RBP dysfunction causes muscle degeneration and neuromuscular disease (NMD). How the timing of RBP function governs the complex cell fate decisions during muscle regeneration is poorly understood. Here, single cell analysis of skeletal muscle regeneration reveals the timing of NMD-associated RBPs expression in muscle progenitors, including a massive upregulation of Hnrnpa2b1 (A2b1). more...

(Submitter supplied) The RNA localization mechanisms in muscle are incompletely known however numerous RNA binding proteins and RNA aggregate into higher order amyloid-like assemblies in degenerative muscle disease. Here we assign a role for the RNA binding protein hnRNPA2B1, heterogeneous RNA binding protein A2/B1, in normal myogenesis. Loss of hnRNPA2/B1 impairs muscle differentiation in vitro. hnRNPA2B1 binds to the 3’UTR of select myogeneic transcripts distinct from other RNA-binding proteins during muscle differentiation. more...

(Submitter supplied) We report the application of single myofiber ATAC-Seq (smfATAC-Seq) to investigate the chromatin accessibility of a single myofiber without the presence of confounding muscle resident cell types. This method demonstrates that open chromatin regions of myonuclei can be tagmentated and high-quality sequencing ready libraries can be generated from these fragments. To perform comparative analysis as well as to demonstrate the applicability of the smfATAC-Sew to study changes in chromatin of myonuclei within different contexts, smfATAC-Seq was performed both on uninjured myofibers as well as injured myofibers seven days after induced injury. more...

(Submitter supplied) The function of skeletal muscle stem cells (MuSC) declines during aging, contributing to the advent of age-related myopathies. However, whether this decline is the result of accumulating cellular damage, altered heterogeneity in stem cell populations or due to the effect of the changing niche environment remains largely unknown. By scRNA-Seq, we show that the age-related reduction in the MuSC pool is not stochastic, with different subpopulations being distinctly affected in aging. more...

(Submitter supplied) We developed a method of combining single myofiber isolation with SMART-seq to analyze the whole transcriptome of single myofibers. Here we apply this technique to analyze the variation in the transcriptome of young (4 weeks) and old (19 months) mice. We see the deregulation of a variety of genes that have been reported, or may cause, the deterioration of the muscle in aging. This confirms the applicability of our novel technique for use in analyzing the transcriptome of individual myofibers under various different conditions.
