    MyoD Is a 3D Genome Structure Organizer for Muscle Cell Identity

    Investigators showed that MyoD functioned as a “genome organizer” that specified 3D genome architecture unique to muscle cell development, and that H3K27ac was insufficient for the establishment of MyoD-induced chromatin loops in muscle cells.

    Molecular Mechanisms behind Persistent Presence of Parvovirus B19 in Human Dilated Myocardium

    Researchers measured the levels of inflammation, fibrosis, apoptosis, and necrosis in endomyocardial biopsies and sera of nonischemic parvovirus(PV) B19-positive and PVB19-negative dilated cardiomyopathy patients.

    A20 (TNFAIP3) Alleviates Viral Myocarditis through ADAR1/miR-1a-3p-Dependent Regulation

    A20 was underexpressed and miR-1a-3p was overexpressed in the myocardium of viral myocarditis mice as well as in Coxsackie virus B3-infected cardiomyocytes.

    Clenbuterol Exerts Antidiabetic Activity through Metabolic Reprogramming of Skeletal Muscle Cells

    To elucidate the underlying cellular and molecular mechanisms of metabolic reprogramming, researchers chronically treated wild-type mice and several newly developed mutant mouse strains with clenbuterol, a selective β2-adrenergic receptor agonist.

    Dynamics of Skeletal Muscle-Resident Stem Cells during Myogenesis in Fibrodysplasia Ossificans Progressiva

    Scientists demonstrated that while two resident stem cell populations, muscle stem cells (MuSCs) and fibro/adipogenic progenitors, had similar proliferation rates after injury, the differentiation potential of mutant MuSCs was compromised.

    LncRNA-XIST Promotes Proliferation and Migration in ox-LDL Stimulated Vascular Smooth Muscle Cells through miR-539-5p/SPP1 Axis

    Researchers discovered the possible role and mechanism of long coding RNA X-inactivate specific transcript (XIST) in oxidized low-density lipoprotein (ox-LDL) – stimulated vascular smooth muscle cells, which could further help evalute its possible a role in the progression of atherosclerosis.

    2-Benzyllawsone Protects against Polymicrobial Sepsis and Vascular Hyporeactivity in Swiss Albino Mice

    Evaluation of 2-benzyllawsone against vascular hyporeactivity, hypotension, and sepsis-related inflammation and infection was carried out in the cecal ligation and puncture model in Swiss albino mice and aortic smooth muscle cells in vitro.

    The Orphan Receptor GPRC5B Activates Pro-inflammatory Signaling in the Vascular Wall via Fyn and NFκB

    In endothelial cells and vascular smooth muscle cells, stimulation with high glucose, TNFα or LPS induced a significant upregulation of endogenous G-protein coupled receptor 5B of family C (GPRC5B) mRNA and protein levels.
