    Aorta smooth muscle-on-a-chip reveals impaired mitochondrial dynamics as a therapeutic target for aortic aneurysm in bicuspid aortic valve disease

    Mieradilijiang Abudupataer, Shichao Zhu ... Weijia Zhang
    An aorta smooth muscle-on-a-chip model indicated that NOTCH1 insufficiency in HAoSMCs induced phenotypic switching from a contractile to a synthetic phenotype accompanied by an impairment of mitochondrial fusion, implying its potential role as a therapeutic target for BAV-TAA.

    Mitochondrial MICOS complex genes, implicated in hypoplastic left heart syndrome, maintain cardiac contractility and actomyosin integrity

    Katja Birker, Shuchao Ge ... Rolf Bodmer
    Genes of the MICOS complex are a major candidate pathway to be potentially linked to defects in cardiomyocyte growth and differentiation in Hypoplastic left heart syndrome (HLHS), and relevant for elucidating the polygenic nature of HLHS and other CHDs.

    Burst mitofusin activation reverses neuromuscular dysfunction in murine CMT2A

    Antonietta Franco, Xiawei Dang ... Gerald W Dorn II
    A trial of mitofusin activation shows neuron regeneration and phenotype reversal in vitro and in vivo in experimental Charcot–Marie–Tooth disease type 2A caused by mitofusin 2 mutations.

    Loss of flavin adenine dinucleotide (FAD) impairs sperm function and male reproductive advantage in C. elegans

    Chia-An Yen, Dana L Ruter ... Sean P Curran
    Loss of FAD stemming from cell autonomous defects in mitochondrial proline catabolism impairs sperm quality male reproductive advantage in C. elegans.

    AAV-Txnip prolongs cone survival and vision in mouse models of retinitis pigmentosa

    Yunlu Xue, Sean K Wang ... Constance L Cepko
    AAV-Txnip prolongs vision in mouse models of blindness, enhancing lactate catabolism, mitochondrial health, and ATP production in a condition that likely has a limited glucose supply.

    Unbiased proteomics, histochemistry, and mitochondrial DNA copy number reveal better mitochondrial health in muscle of high-functioning octogenarians

    Ceereena Ubaida-Mohien, Sally Spendiff ... Russell T Hepple
    Skeletal muscle from world-class octogenarian athletes, representing a population with very high physical function in advanced age, exhibits greater mass and strength that is associated with overrepresentation of proteins involved in mitochondrial biology and more oxidatively competent muscle fibers.

    Reorganization of the flagellum scaffolding induces a sperm standstill during fertilization

    Martina Jabloñski, Guillermina M Luque ... Mariano G Buffone
    The double helix actin network surrounding the mitochondrial sheath of the sperm midpiece undergoes structural changes prior to the motility cessation during sperm-egg fusion.
