    Sex-Specific Control of Human Heart Maturation by the Progesterone Receptor

    Functional validation studies of sex steroids implicated in cardiac maturation were performed in human pluripotent stem cell-derived cardiac organoids and mice.
    [Circulation]

    Abstract

    Establishment of an In Vitro Safety Assessment Model for Lipid-Lowering Drugs Using Same-Origin Human Pluripotent Stem Cell-Derived Cardiomyocytes and Endothelial Cells

    Investigators established a preclinical toxicology model using same-origin human pluripotent stem cell-differentiated cardiomyocytes and endothelial cells.

    Abstract

    Antagonistic Control of Myofiber Size and Muscle Protein Quality Control by the Ubiquitin Ligase UBR4 during Aging

    Researchers found that the levels of the ubiquitin ligase UBR4 increased in skeletal muscle with aging, and that UBR4 increased the proteolytic activity of the proteasome.

    Atx Regulates Skeletal Muscle Regeneration via LPAR1 and Promotes Hypertrophy

    The authors showed that autotaxin (Atx) expression and activity was required for satellite cell differentiation. Conditional ablation of Atx or its pharmacological inhibition impaired muscle repair.

    hnRNP L Is Essential for Myogenic Differentiation and Modulates Myotonic Dystrophy Pathologies

    Investigators evaluated the functional role of hnRNP L in normal and myotonic dystrophy type 1 (DM1) muscle cells. They sought to test if modulation of hnRNP L expression affected DM1 splicing targets and myogenic outcomes.

    Abstract

    Circular RNA Calm4 Regulates Hypoxia-Induced Pulmonary Arterial Smooth Muscle Cells Pyroptosis via the Circ-Calm4/miR-124-3p/PDCD6 Axis

    Researchers showed evidence for the involvement of a specific circular RNA known as circ-Calm4 in pulmonary hypertension and the underlying signaling pathway in pyroptosis.

    Stimulation of Vascular Smooth Muscle Cell Proliferation by Stiff Matrix via the IKCa Channel‐Dependent Ca2+ Signaling

    The authors examined the role of the intermediate‐conductance Ca2+‐activated K+ channel in the matrix stiffness regulation of vascular smooth muscle cell proliferation by growing A7r5 cells on soft and stiff polydimethylsiloxane substrates with stiffness close to these of arteries under physiological and pathological conditions, respectively.

    Abstract

    HIF2A Gain-of-Function Mutation Modulates the Stiffness of Smooth Muscle Cells and Compromises Vascular Mechanics

    Researchers generated hypoxia-inducible factor 2α (HIF2A) gain-of-function induced pluripotent stem cells and differentiated them into endothelial cells and smooth muscle cells.

    Muscle Stem Cell Quiescence: Controlling Stemness by Staying Asleep

    The authors review the current understanding of muscle stem cell quiescence and highlight recently discovered molecular markers, which differentiate depth of quiescence and influence self-renewal capacity.
