    Evolutionary loss of foot muscle during development with characteristics of atrophy and no evidence of cell death

    Mai P Tran et al.
    Evolutionary loss of foot muscle in a bipedal rodent shares similarities with skeletal muscle atrophy, which is typically considered a pathological response to injury or disease.

    Chronic muscle weakness and mitochondrial dysfunction in the absence of sustained atrophy in a preclinical sepsis model

    Allison M Owen et al.
    Sepsis-induced long-term muscle weakness was reproduced using a refined murine model, which was accompanied by mitochondrial dysfunction in the absence of sustained atrophy, suggesting the promise of mitochondria-targeted post-sepsis therapies.

    Transcriptional activator TAp63 is upregulated in muscular atrophy during ALS and induces the pro-atrophic ubiquitin ligase Trim63

    Yannick von Grabowiecki et al.
    Atrophic muscles of patients and animal models developing amyotrophic lateral sclerosis show an upregulation of TAp63 that stimulates the expression of a pro-atrophic ubiquitin ligase.

    Frizzled3 controls axonal development in distinct populations of cranial and spinal motor neurons

    Zhong L Hua et al.
    The signaling molecule Frizzled3 plays a part in the development of the nervous system by controlling the ability of motor neurons to form connections with distant target muscles.

    Abelson tyrosine-protein kinase 2 regulates myoblast proliferation and controls muscle fiber length

    Jennifer K Lee et al.
    Abl2 regulates myoblast proliferation, thereby controlling the size of the pool of myoblasts available for fusion, providing insight into mechanisms that control myofiber length and signaling between muscle and tendon.

    Nonsense mRNA suppression via nonstop decay

    Joshua A Arribere, Andrew Z Fire
    Nonstop mRNA decay degrades mRNAs with a premature stop codon after such mRNAs are targeted by the nonsense-mediated decay machinery.

    Genetic screen in Drosophila muscle identifies autophagy-mediated T-tubule remodeling and a Rab2 role in autophagy

    Naonobu Fujita et al.
    Analyses of a developmentally regulated Drosophila myofiber remodeling program provide insight into induced autophagy required for T-tubule membrane reorganization, and uncover a conserved Rab2 role in autophagosome-lysosome fusion.

    Loss of Ptpn11 (Shp2) drives satellite cells into quiescence

    Joscha Griger et al.
    The stem cells of the postnatal muscle allow postnatal muscle growth and repair and withdraw from the cell cycle when the tyrosine phosphatase Ptpn11 (Shp2) is inhibited or mutated in mice.
