PUBLICATIONS(Ranked by impact factor of the journal)CARDIAC MUSCLE CELLSResearchers report the identification of the aging-regulated lncRNA Sarrah that was anti-apoptotic in cardiomyocytes. Importantly, loss of SARRAH in human engineered heart tissue resulted in impaired contractile force development. [Nat Commun] Full Article Functional Arrays of Human Pluripotent Stem Cell-Derived Cardiac Microtissues Scientists report a 96-well-based array of 3D human pluripotent stem cell-derived cardiac microtissues – termed Cardiac MicroRings – in custom 3D-print-molded multiwell plates capable of contractile force measurement. [Sci Rep] Full Article In cardiac-derived H9C2 cells, LM9 treatment suppressed palmitic acid (PA)-induced inflammation, lipid accumulation, and fibrotic responses. LM9 treatment also inhibited PA-activated TLR4/MyD88/NF-κB signaling pathway. [Acta Pharmacol Sin] Abstract The authors showed that lysine deficiency-induced apoptosis in satellite cells was mediated by the JAK2-STAT3 pathway inhibition. [Food Funct] Abstract | Graphical Abstract SKELETAL MUSCLE CELLSMyogenic Progenitor Cell Lineage Specification by CRISPR/Cas9-Based Transcriptional Activators The authors demonstrated that endogenous activation of the PAX7 transcription factor resulted in stable epigenetic remodeling and differentiated human pluripotent stem cells into skeletal myogenic progenitor cells. [Stem Cell Reports] Full Article | Graphical Abstract Researchers describe a design and methods to generate a reusable mold to fabricate a 96-well platform, referred to as MyoTACTIC, that enabled bulk production of 3D human skeletal muscle micro-tissues . [Sci Rep] Full Article SMOOTH MUSCLE CELLSRespiratory restoration by AOX prevented acute hypoxic pulmonary vasoconstriction and hypoxic responses of pulmonary arterial smooth muscle cells, acute hypoxia-induced redox changes of NADH and cytochrome c, and superoxide production. [Sci Adv] Full Article ADGRG6/GPR126, an adhesion GPCR, was increased in pulmonary arterial hypertension-pulmonary artery smooth muscle cells (PASMCs) compared to control-PASMCs. Increased expression of this receptor in control-PASMCs decreased their proliferation. [Br J Pharmacol] Abstract In vascular smooth muscle cells, overexpression of miR-186-5p significantly promoted cell proliferation and migration, while the opposite results were observed when miR-186-5p was downregulated.

REVIEWSA Roadmap for Fixing the Heart: RNA Regulatory Networks in Cardiac Disease The authors focus on RNA regulatory networks in heart disease, most of which are devastating conditions with no known cure. They cover emerging micropeptides, which represent short open reading frames in long noncoding RNA transcripts that may modulate cardiac physiology.

INDUSTRY NEWSVertex Pharmaceuticals Incorporated and Affinia Therapeutics announced that the two companies have entered into a strategic research collaboration to engineer novel adeno-associated virus (AAV) capsids to deliver transformative genetic therapies to people with serious diseases, such as Duchenne muscular dystrophy, myotonic dystrophy type 1 and cystic fibrosis. [Vertex Pharmaceuticals Incorporated] Press Release The Italfarmaco Group announced that an Independent Data Monitoring Committee has recommended the continuation of the trial based on the interim imaging analysis, which showed a lower muscle fat infiltration with Givinostat compared to the placebo group after 12 months of treatment.

POLICY NEWSOpen Science Takes On the Coronavirus Pandemic When reports emerged in late 2019 of an outbreak of a new coronavirus centred in Wuhan, China, researchers at the virological-analysis website Nextstrain were ready. The open-source project tracks the spread of viruses through genetic variations in the sequences that scientists find. [Nature News] Editorial Director of US Agency Key to Vaccine Development Leaves Role Suddenly amid Coronavirus Pandemic Rick Bright, one of the nation’s leading vaccine development experts and the director of the Biomedical Advanced Research and Development Authority, is no longer leading the organization.
