    Chaperone Mediated Autophagy Protects Cardiomyocytes against Hypoxic-Cell Death

    Lysosome-associated membrane protein 2a verexpression and knockdown were used to causally study chaperone-mediated autophagy’s role in hypoxically-stressed cardiomyocytes.
    [American Journal of Physiology-Cell Physiology]

    Abstract

    Depletion of Skeletal Muscle Satellite Cells Attenuates Pathology in Muscular Dystrophy

    Scientists demonstrated that satellite cells initiated expression of the myogenic transcription factor MyoD, which then induced re-expression of fetal genes in the myofibers that destabilized the sarcolemma.

    Mechanosensors Control Skeletal Muscle Mass, Molecular Clocks, and Metabolism

    The authors genetically reduced the expression of mechanosensors integrin-linked kinase and kindlin-2 in myogenic C2C12 cells and analyzed the gene expression of mechanosensors, clock components and metabolism-controlling genes.

    Abstract

    DVL1 and DVL3 Require Nuclear Localization To Regulate Proliferation in Human Myoblasts

    Investigators examined dishevelled (DVL) function in human myogenesis and the muscle-related cancer alveolar rhabdomyosarcoma.

    Selenium Deficiency Leads to Reduced Skeletal Muscle Cell Differentiation by Oxidative Stress in Mice

    A selenium (Se)-deficient skeletal muscle model was established. The skeletal muscle tissue and blood Se content were significantly reduced in the Se deficiency group.
    [Biological Trace Element Research]

    Abstract

    KCNJ8/ABCC9-Containing K-ATP Channel Modulates Brain Vascular Smooth Muscle Development and Neurovascular Coupling

    Scientists demonstrated a role for KCNJ8/ABCC9-containing ATP-sensitive potassium channel (K-ATP) channels in the differentiation of brain vascular smooth muscle cell, which in turn was necessary for fine-tuning of cerebral blood flow.

    Stromal AR Inhibits Prostate Tumor Progression by Restraining Secretory Luminal Epithelial Cells

    Researchers specifically deleted androgen receptor in smooth muscle cells of the adult mouse prostate under two tumorigenic conditions, namely, the Hi-Myc genetic model and the T + E2 hormonal carcinogenesis model.

    Focal Adhesion Kinase–Related Pathways May Be Suppressed by Metformin in Vascular Smooth Muscle Cells in High Glucose Conditions

    The focal adhesion kinase (FAK) gene expression levels and phosphorylated FAK protein values were evaluated in vascular smooth muscle cells treated with different doses of metformin, based on cell viability using quantitative reverse transcription PCR, western blotting and methyl thiazol tetrazolium techniques.
