    Myonuclear accretion is a determinant of exercise-induced remodeling in skeletal muscle

    Qingnian Goh, Taejeong Song ... Douglas P Millay
    Fusion of muscle progenitors drives continuous myonuclear accretion during exercise and impacts various adaptations in skeletal muscle including response to injury and hypertrophy.

    Synergy between Wsp1 and Dip1 may initiate assembly of endocytic actin networks

    Connor J Balzer, Michael L James ... Brad J Nolen
    An activator of branching nucleation by Arp2/3 complex directly synergizes with an activator of linear filament nucleation to initiate assembly of actin networks that drive endocytosis.

    The control and training of single motor units in isometric tasks are constrained by a common input signal

    Mario Bräcklein, Deren Yusuf Barsakcioglu ... Dario Farina
    Humans trained to flexibly control individual motor units within a muscle do not naturally learn to gain control over recruitment order.

    Muscle function and homeostasis require cytokine inhibition of AKT activity in Drosophila

    Katrin Kierdorf, Fabian Hersperger ... Marc S Dionne
    A cytokine partly derived from macrophages is required to promote normal muscle health and metabolism by inhibiting the activity of the insulin signalling pathway in the fruitfly Drosophila melanogaster.

    Myogenic regulatory transcription factors regulate growth in rhabdomyosarcoma

    Inês M Tenente, Madeline N Hayes ... David M Langenau
    MYF5 and MYOD regulate rhabdomyosaroma growth and tumor-propagating potential, acting more than as passive markers retained from the target cell-of-origin during transformation.

    Agonist efficiency links binding and gating in a nicotinic receptor

    Dinesh C Indurthi, Anthony Auerbach
    Efficiency measures the fundamental link between agonist binding and protein conformational change, and in nicotinic receptors has 5 values that calibrate energy changes in the induced fit that triggers activation.

    Tuning of feedforward control enables stable muscle force-length dynamics after loss of autogenic proprioceptive feedback

    Joanne C Gordon, Natalie C Holt ... Monica A Daley
    Running guinea fowl maintain stable running after loss of the stretch reflex in a major ankle extensor muscle, by increasing feedforward muscle activation to maintain ankle stiffness and work output.

    Intramuscular Neurotrophin-3 normalizes low threshold spinal reflexes, reduces spasms and improves mobility after bilateral corticospinal tract injury in rats

    Claudia Kathe, Thomas Haynes Hutson ... Lawrence David Falcon Moon
    Delayed intramuscular gene therapy with neurotrophin-3 after corticospinal tract injury reduces spasticity and improves locomotion by treating underlying causes of spasticity.
