    Cardiomyocyte-GSK-3β Deficiency Induces Cardiac Progenitor Cell Proliferation in the Ischemic Heart through Paracrine Mechanisms

    Researchers identified the potential roles of glycogen synthase kinase-3β (GSK-3β), a critical regulator of cell proliferation and differentiation, in cardiac progenitor cell proliferation post-myocardial infarction.
    [Journal of Cellular Physiology]

    Abstract

    Positive Feedback Loop of lncRNA SNHG1/miR-16-5p/GATA4 in the Regulation of Hypoxia/Reoxygenation-Induced Cardiomyocyte Injury

    The authors explored the role and molecular mechanism of long non-coding RNA small nucleolar RNA host gene 1 (SNHG1) in ischemic cardiomyocyte injury.

    Abstract

    Bi-Phasic Effect of Gelatin in Myogenesis and Skeletal Muscle Regeneration

    Researchers elaborated on a bi-phasic effect of gelatin in skeletal muscle regeneration, mediated by hormetic effects of reactive oxygen species.

    Abstract

    Evaluating the Role of Nitric Oxide in Myogenesis In Vitro

    The authors clarified the role of nitric oxide (NO) in myoblast proliferation, migration and differentiation. Baseline NO levels were established in vitro, whereafter NO levels were manipulated during myogenesis using L-NAME or SIN-1.

    Abstract

    ATP-Sensitive Potassium Channels in Zebrafish Cardiac and Vascular Smooth Muscle

    Using a comprehensive combination of genetically modified fish, electrophysiology, and gene expression analysis, scientists demonstrated that zebra fish cardiac myocytes and vascular smooth muscle expressed functional ATP-sensitive potassium channels channels of similar subunit composition, structure, and metabolic sensitivity to their mammalian counterparts.
