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.
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.

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-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.

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.
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.

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.
