    Improvement of muscle strength in a mouse model for congenital myopathy treated with HDAC and DNA methyltransferase inhibitors

    Alexis Ruiz, Sofia Benucci ... Francesco Zorzato
    Physiological and biochemical studies show that the treatment of a transgenic mouse model carrying recessive Ryr1 mutations with a combination of class II histone deacetylase inhibitors and DNA methyl transferase inhibitors significantly improves skeletal muscle function.

    Potassium dependent rescue of a myopathy with core-like structures in mouse

    M Gartz Hanson, Jonathan J Wilde ... Lee Niswander
    A mouse model of human muscle myopathy is used to provide mechanistic insight, identify possible biomarkers of disease, and suggest possible therapeutic strategies to alleviate muscle weakness.

    Dynamic regulation of inter-organelle communication by ubiquitylation controls skeletal muscle development and disease onset

    Arian Mansur, Remi Joseph ... Vandana A Gupta
    Novel disease pathways underlie disease pathogenesis in Kelch-related nemaline myopathy through proteomic remodeling.

    Quantitative proteomic analysis of skeletal muscles from wild-type and transgenic mice carrying recessive Ryr1 mutations linked to congenital myopathies

    Jan Eckhardt, Alexis Ruiz ... Francesco Zorzato
    Quantitative proteomic analysis shows that recessive Ryr1 mutations not only decrease the content of RyR1 protein in muscle, but also affect the content of many other proteins involved in a variety of biological processes.

    Isoform-specific mutation in Dystonin-b gene causes late-onset protein aggregate myopathy and cardiomyopathy

    Nozomu Yoshioka, Masayuki Kurose ... Hirohide Takebayashi
    Dystonin-b-specific mutant mice exhibit late-onset myopathy and cardiomyopathy.

    KLHL41 stabilizes skeletal muscle sarcomeres by nonproteolytic ubiquitination

    Andres Ramirez-Martinez, Bercin Kutluk Cenik ... Eric N Olson
    KLHL41 acts as a poly-ubiquitin dependent chaperone that prevents the formation of pathogenic nebulin aggregates associated with muscle disease.

    Dynamic clustering of dynamin-amphiphysin helices regulates membrane constriction and fission coupled with GTP hydrolysis

    Tetsuya Takeda, Toshiya Kozai ... Kohji Takei
    A new approach using combination of electron microscopy (EM) and high-speed atomic force microscopy (HS-AFM) clearly demonstrates dynamics of dynamin-amphiphysin complexes during membrane constriction and fission suggesting a novel 'clusterase' model of the dynamin-mediated membrane fission.

    Ankyrin-B is a PI3P effector that promotes polarized α5β1-integrin recycling via recruiting RabGAP1L to early endosomes

    Fangfei Qu, Damaris N Lorenzo ... Vann Bennett
    Ankyrin-B – through interactions with PI3P lipids, dynactin and RabGAP1L – functions as a critical node in the protein circuitry underlying polarized recycling of α5β1-integrin to enable haptotaxis along fibronectin gradients.

    The long noncoding RNA Charme supervises cardiomyocyte maturation by controlling cell differentiation programs in the developing heart

    Valeria Taliani, Giulia Buonaiuto ... Monica Ballarino
    The lncRNA pCharme controls the expression of cardiomyocyte maturation genes and heart development by orchestrating the formation of MATR3-enriched nuclear condensates.
