    Catalpol Protects AC16 Cells from Hypoxia/Reoxygenation Injury by Regulating the miR-22-3p/DPP4 Axis

    Catalpol promoted the viability and reduced cell apoptosis of human cardiomyocyte AC16 cells and repressed the release of inflammatory cytokines TNF-α, IL-6, and IL-1β, while inhibiting the leakage of myocardial injury markers lactate dehydrogenase and creatine kinase.

    Abstract

    Single-Cell Transcriptomics Reveals Cell-Type-Specific Diversification in Human Heart Failure

    The authors identified cell-specific transcriptional signatures associated with age and heart failure and revealed the emergence of disease-associated cell states.

    Primary Cilia on Muscle Stem Cells Are Critical to Maintain Regenerative Capacity and Are Lost during Aging

    Investigators found that the ability of muscle stem cells to regenerate was regulated by the primary cilium, a cellular protrusion that served as a sensitive sensory organelle.

    Skeletal Muscle-Specific Overexpression of miR-486 Limits Mammary Tumor-Induced Skeletal Muscle Functional Limitations

    To determine whether skeletal muscle miR-486 was functionally similar in dystrophies and cancer, the authors performed functional limitations and biochemical studies of skeletal muscles of MMTV-Neu mice that mimicked HER2+ breast cancer and MMTV-PyMT mice that mimicked luminal subtype B breast cancer.

    Abstract

    Galectin-1 Prevents Pathological Vascular Remodeling in Atherosclerosis and Abdominal Aortic Aneurysm

    Scientists analyzed the role of galectin-1, a β-galactoside–binding protein, as a therapeutic target for atherosclerosis and abdominal aortic aneurysm.

    Aged Bone Matrix-Derived Extracellular Vesicles as a Messenger for Calcification Paradox

    The authors showed that extracellular vesicles derived from aged bone matrix during bone resorption favored bone marrow mesenchymal stem cell adipogenesis rather than osteogenesis and augmented calcification of vascular smooth muscle cells.

    Targeting the Sarcomere in Inherited Cardiomyopathies

    The authors discuss the therapeutic strategies to alter sarcomere contractile activity and summarize the data indicating that targeting one protein in the sarcomere can be effective in treating patients with genetic variants in other sarcomeric proteins, as well as in patients with non-sarcomere-based disease.

    Abstract

    Systems for the Functional Evaluation of Human Heart Tissues Derived from Pluripotent Stem Cells

    Scientists review various modalities to evaluate the function of human stem cell-derived cardiac tissues and introduce heart-on-a-chip systems that can recapitulate physiological parameters of human pluripotent stem cell-derived cardiac tissues.
