    N-n-Butyl Haloperidol Iodide Mediates Cardioprotection via Regulating AMPK/FoxO1 Signaling

    The authors identified N-n-butyl haloperidol iodide (F2)-mediated nuclear accumulation of forkhead box O1 (FoxO1) is dependent on AMP-activated protein kinase (AMPK), as blockage of AMPK with compound C induced nuclear exit of FoxO1.

    TRPV4 Blockade Alleviates Endoplasmic Reticulum Stress Mediated Apoptosis in Hypoxia–Induced Cardiomyocyte Injury

    The ability of transient receptor potential vanilloid 4 (TRPV4) to modulate the endoplasmic reticulum stress and apoptosis was assessed in vitro through the administration of the TRPV4 antagonist HC-067047 or the agonist GSK1016790A.

    Iron Deficiency–Induced Ferritinophagy Impairs Skeletal Muscle Regeneration through RNF20-Mediated H2Bub1 Modification

    Investigators demonstrated that iron deficiency-mediated ferritinophagy impeded myogenic differentiation. Mechanistically, ferritinophagy induced RNF20 degradation through the autophagy-lysosomal pathway.

    MicroRNA-92b in the Skeletal Muscle Regulates Exercise Capacity via Modulation of Glucose Metabolism

    Adeno-associated virus-mediated skeletal muscle miR-92b overexpression in C57BLKS/J mice, and global knockout of miR-92b mice were used to explore the function of miR-92b in glycogen and lactate metabolism in skeletal muscle.

    MCUb Is an Inducible Regulator of Calcium-Dependent Mitochondrial Metabolism and Substrate Utilization in Muscle

    Researchers showed that mitochondrial Ca2+ uniporter (MCU) b, an inhibitor of MCU-mediated Ca2+ influx, was induced by caloric restriction, where it increased mitochondrial fatty acid utilization.

    BACH1 Regulates the Differentiation of Vascular Smooth Muscle Cells from Human Embryonic Stem Cells via CARM1-Mediated Methylation of H3R17

    The authors found that the loss of BACH1 in human embryonic stem cells (hESCs) attenuated the expression of vascular smooth muscle cell (VSMC) marker genes, whereas overexpression of BACH1 after mesoderm induction increased the expression of VSMC markers during in vitro hESC-VSMC differentiation.
