  Linc-YY1 promotes myogenic differentiation and muscle regeneration through an interaction with the transcription factor YY1

  Long intervening noncoding RNAs (lincRNAs) are an emerging class of molecular regulators with diverse functions. Here the authors identify Linc-YY1, a novel lincRNA transcribed from the noncoding region of the mouse YY1 gene, that binds to YY1 protein and thereby regulates skeletal muscle differentiation and regeneration.

  TAK1 modulates satellite stem cell homeostasis and skeletal muscle repair

  TAK1 is a MEK kinase family member that activates pro-survival NF-kB signalling but also pro-apoptotic caspase signalling in various cell types. Here the authors show that satellite-cell specific deletion of TAK1 in mice depletes the muscle stem cell pool and thus limits myofibre regeneration after injury.

  Osteoclasts control reactivation of dormant myeloma cells by remodelling the endosteal niche

  Therapy resistant dormant myeloma cells contribute to disease relapse. Here, the authors use intravital microscopy to track the location of these cells and demonstrate that they hone to the endosteal niche within the bone.

  Direct optical activation of skeletal muscle fibres efficiently controls muscle contraction and attenuates denervation atrophy

  Nerve damage can lead to skeletal muscle paralysis and atrophy. Here, the authors show that localized photostimulation of mouse calf muscle expressing the light-sensitive channel Channelrhodopsin-2 generates contraction in the absence of neural impulses and prove that this strategy can be used to prevent muscle atrophy.

  Tbx15 controls skeletal muscle fibre-type determination and muscle metabolism

  The transcriptional regulator Tbx15 has a role in organ development. Here Lee et al.show that Tbx15 influences fibre-type determination in murine skeletal muscles, explaining local and systemic metabolic derangements in heterozygous Tbx15 knockout mice.

  Turning terminally differentiated skeletal muscle cells into regenerative progenitors

  Newts can regenerate amputated limbs via unknown mechanism involving dedifferentiation of cells in the stump into progenitors that contribute to the new appendages. Here the authors show that skeletal muscle dedifferentiation in regenerating newt limbs relies on a diverted programmed cell death response by myofibers.

  Muscle stem cells contribute to myofibres in sedentary adult mice

  Skeletal muscle satellite cells are muscle stem cells believed to contribute only to regenerating myofibres. Here Keefe et al. show that in adult sedentary mice satellite cells continue to fuse with uninjured myofibres, but they are not globally required for the maintenance of aging muscles.
