    Extensive alternative splicing transitions during postnatal skeletal muscle development are required for calcium handling functions

    Amy E Brinegar, Zheng Xia ... Thomas A Cooper
    Global transcriptome changes, particularly alternative splicing, are highly dynamic the first 2 weeks after birth, and the example of calcineurin A splicing exemplifies the importance of alternative splicing during skeletal muscle development.

    High-intensity interval training remodels the proteome and acetylome of human skeletal muscle

    Morten Hostrup, Anders Krogh Lemminger ... Atul Shahaji Deshmukh
    Global proteomic and acetylomic analyses reveal how skeletal muscle adapts to high-intensity interval training including adaptations to processes regulating metabolism and contraction.

    The IRE1/XBP1 signaling axis promotes skeletal muscle regeneration through a cell non-autonomous mechanism

    Anirban Roy, Meiricris Tomaz da Silva ... Ashok Kumar
    The IRE1/XBP1 signaling in myofibers is essential for robust skeletal muscle regeneration in response to injury.

    Remodeling of skeletal muscle myosin metabolic states in hibernating mammals

    Christopher TA Lewis, Elise G Melhedegaard ... Julien Ochala
    During hibernation, animals remodel the structure of their relaxed muscle via a protein called myosin and this enables vast temperature changes.

    The biphasic and age-dependent impact of klotho on hallmarks of aging and skeletal muscle function

    Zachary Clemens, Sruthi Sivakumar ... Fabrisia Ambrosio
    Transcriptomic analysis using a novel information-based network entropy approach provides mechanistic insights into the ability of Klotho to successfully ameliorate age-related sarcopenia in old mice, but not oldest-old mice.

    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.

    Proteomic analysis shows decreased type I fibers and ectopic fat accumulation in skeletal muscle from women with PCOS

    Elisabet Stener-Victorin, Gustaw Eriksson ... Anna Benrick
    Elevated levels of ectopic fat and a decreased number of oxidative insulin-sensitive type I muscle fibers in skeletal muscle could lead to insulin resistance in women with polycystic ovary syndrome.

    A MSTNDel73C mutation with FGF5 knockout sheep by CRISPR/Cas9 promotes skeletal muscle myofiber hyperplasia

    Ming-Ming Chen, Yue Zhao ... Zheng-Xing Lian
    Newly prepared double gene-edited sheep provide excellent models for skeletal muscle growth and development, and muscle diseases such as muscle atrophy and sarcopenia.

    TBP/TFIID-dependent activation of MyoD target genes in skeletal muscle cells

    Barbora Malecova, Alessandra Dall'Agnese ... Pier Lorenzo Puri
    Genetic and biochemical evidence shows that the basal transcription machinery of muscle cells invariably relies on TBP/TFIID because TBP2 is not expressed in muscle cells, and thus resolves a longstanding issue raised by previous conflicting data.

    LSD1 defines the fiber type-selective responsiveness to environmental stress in skeletal muscle

    Hirotaka Araki, Shinjiro Hino ... Mitsuyoshi Nakao
    Lysine-specific demethylase-1 acts as an epigenetic barrier against glucocorticoid-induced atrophy and exercise-induced hypertrophy in skeletal muscle.
