PUBLICATIONS(Ranked by impact factor of the journal)CARDIAC MUSCLE CELLSDek Modulates Global Intron Retention during Muscle Stem Cells Quiescence Exit Intron-retained transcripts found in quiescent satellite cells were essential for fundamental functions including RNA splicing, protein translation, cell-cycle entry, and lineage specification. [Dev Cell] Full Article | Graphical Abstract Drug Response Analysis for Scaffold-Free Cardiac Constructs Fabricated Using Bio-3D Printer Scientists developed a method to measure the contractile force and to evaluate the drug response in cardiac constructs. [Sci Rep] Full Article SKELETAL MUSCLE CELLSThe authors showed that changes in muscle growth driven by autonomous modulation of insulin receptor signaling produced corresponding changes in synapse size, with each muscle affecting only its presynaptic motor neuron branches. [Dev Cell] Full Article | Graphical Abstract miR-379 Links Glucocorticoid Treatment with Mitochondrial Response in Duchenne Muscular Dystrophy Scientists confirmed in myoblasts that EIF4G2 was a direct target of miR-379, and identified the DAPIT mitochondrial protein as a translational target of EIF4G2. [Sci Rep] Full Article SMOOTH MUSCLE CELLSInvestigators explored the role of long-noncoding RNA ANRIL in ox-LDL-induced phenotypic transition of human aortic smooth muscle cells. [Cell Death Dis] Full Article In vitro studies demonstrated that the inhibition of TRPV4 channels mitigated aortic smooth muscle cell-dependent inflammatory cytokine production as well as decreased neutrophil transmigration through aortic endothelial cells. [FASEB J] Full Article Scientists demonstrated that the intravenous injection of umbilical cord-MSC attenuated elastase induced aneurysmal expansion, reduced elastin degradation and fragmentation, inhibited MMPs and TNF-α expression, preserved and/or restored vascular smooth muscle cell contractile phenotype in abdominal aortic aneurysm. [Stem Cells Dev] Abstract In human aortic smooth muscle cells, AK131850 overexpression led to downregulated, while AK131850 siRNA silencing led to upregulated TGF-β1.

INDUSTRY NEWSDuchenne UK and Parent Project Muscular Dystrophy Announce 2020 Joint Research Grant Call Parent Project Muscular Dystrophy and Duchenne UK announced the launch of their joint 2020 Research Grant Call, inviting research proposals for submission and review. Up to $1 million will be awarded to a project or projects seeking to minimize the immunological issues of gene therapy to treat Duchenne. [Parent Project Muscular Dystrophy] Press Release Santhera Pharmaceuticals announced that partner ReveraGen Biopharma Inc. has completed a long-term, open-label extension study of 24 months duration with vamorolone in patients with Duchenne muscular dystrophy. [Santhera Pharmaceuticals] Press Release The Minneapolis Heart Institute Foundation® announced that it is conducting additional research on a novel hydrogel that is designed to repair cardiac tissue. In April 2020, the FDA approved an investigational new drug application to investigate the safety and feasibility of delivering VentriGel via catheter into areas of the heart of patients that cannot be completely revascularized at the time of coronary artery bypass grafting.

POLICY NEWSAs Pandemic Pounds US Universities, Federal Support Helps Their Labs Stay Afloat This spring, as the coronavirus pandemic shuttered US higher education, many college presidents began to warn of the dire financial impact of a frozen US economy on their institutions. Their mix of revenue sources largely determined how much they might be hurt. [ScienceInsider] Editorial As the Pandemic Hits Campus Finances, Faculty Face Layoffs The pandemic has bored holes in budgets at universities and colleges across the US and beyond. To stem the spread of the coronavirus, higher education institutions shuttered their campuses, sent students home, and moved classes online. [The Scientist] Editorial
