    Global and local tension measurements in biomimetic skeletal muscle tissues reveals early mechanical homeostasis

    Arne D Hofemeier, Tamara Limon ... Timo Betz
    Combining global and local force measurements of reconstituted muscle tissue using a new chamber system that is compatible with high-resolution microscopy shows mechanical homeostasis already within a week.

    Transcriptomic analyses reveal rhythmic and CLOCK-driven pathways in human skeletal muscle

    Laurent Perrin, Ursula Loizides-Mangold ... Charna Dibner
    Rhythmic transcriptome analyses of human skeletal muscle tissue and cultured primary myotubes reveal an essential role for the circadian coordination of glucose homeostasis and lipid metabolism in human skeletal muscle.

    Bmal1 function in skeletal muscle regulates sleep

    J Christopher Ehlen, Allison J Brager ... Ketema N Paul
    Expression of transcription factor BMAL1 in skeletal muscle reduces the recovery response to sleep loss and is both necessary and sufficient to regulate total sleep amount.

    R-spondin 3 deletion induces Erk phosphorylation to enhance Wnt signaling and promote bone formation in the appendicular skeleton

    Kenichi Nagano, Kei Yamana ... Roland Baron
    R-spondin3 global haplo-insufficiency or its deletion in pre-osteoblasts lead to gain of bone mass in the appendicular skeleton with no or opposite phenotype in the axial skeleton.

    Post-transcriptional regulation of satellite cell quiescence by TTP-mediated mRNA decay

    Melissa A Hausburg, Jason D Doles ... Bradley B Olwin
    The protein Tristetraprolin promotes the decay of MyoD mRNA to maintain satellite cell quiescence.

    Sleep: It's not all in the brain

    Lauren J Francey, John B Hogenesch
    A clock gene expressed in skeletal muscle plays a bigger role in regulating sleep than it does in the brain.

    Osteocytes regulate senescence of bone and bone marrow

    Peng Ding, Chuan Gao ... Junjie Gao
    Partial ablation of osteocytes alters lineage cell specifications in bone and bone marrow, resulting in the acceleration of skeletal aging.

    Inhibition of CERS1 in skeletal muscle exacerbates age-related muscle dysfunction

    Martin Wohlwend, Pirkka-Pekka Laurila ... Johan Auwerx
    CERS1 reduction in aging skeletal muscle contributes to impaired muscle function, myogenesis and increases inflammation and fibrosis, highlighting the significance of very long chain ceramides in age-related muscle homeostasis.

    Endothelial cell signature in muscle stem cells validated by VEGFA-FLT1-AKT1 axis promoting survival of muscle stem cell

    Mayank Verma, Yoko Asakura ... Atsushi Asakura
    Bulk and single-cell RNA-seq data demonstrated that muscle stem cells express low levels of canonical endothelial cell markers, including VEGFA receptors, and VEGFA-FLT1 pathway has a drastic effect on muscle stem cell survival through AKT1 in vitro and in vivo.

    miRNA-27a is essential for bone remodeling by modulating p62-mediated osteoclast signaling

    Shumin Wang, Eri O Maruyama ... Takamitsu Maruyama
    The loss of miRNA-27a stimulates osteoclast-mediated bone resorption but does not affect osteoblast-mediated bone formation, leading to the development of osteoporosis in mice.
