... and behaviour are fundamentally important for understanding how disease, molecules and drugs affect cell function in vivo . Here, by using muscle stem cell (muSC) responses to injury in zebrafish as our biological paradigm, we established a ‘ground truth’ for muSC behaviour. This revealed that segmentation...

... the mechanisms or significance that underlies distinct lysosomal morphologies. Here, we found an extensive tubular autolysosomal network in Drosophila abdominal muscle remodeling during metamorphosis. The tubular network transiently appeared and exhibited the capacity to degrade autophagic cargoes. The tubular...

Of these stressors, loss of the genes that cause muscle detachment produced the strongest levels of JAK-STAT activation. In one of these mutants, fondue ( fon ), we also...

...Maik Drechsler; Heiko Meyer; Ariane C. Wilmes; Achim Paululat ABSTRACT Somatic muscles are formed by the iterative fusion of myoblasts into muscle fibres. This process is driven by the recurrent recruitment of proteins to the cell membrane to induce F-actin nucleation at the fusion site. Although...

At birth, ATAD3 muscle KO mice had normal weight, but from 2 months onwards they showed progressive motor-impaired coordination and weakness. Loss of ATAD3 caused early and severe...

...Alexander L. Auld; Sacha A. Roberts; Ciaran B. Murphy; Jaclyn M. Camuglia; Eric S. Folker ABSTRACT During muscle development, myonuclei undergo a complex set of movements that result in evenly spaced nuclei throughout the muscle cell. In Drosophila , two separate pools of Kinesin and Dynein work...

..., we show that these effects are also reflected at the organism level, as there is a loss of skeletal muscle mass in nestin −/− (NesKO) mice, reflected as reduced lean (muscle) mass in the mice. Further examination of muscles in male mice revealed that these effects stemmed from nestin-deficient...

These data suggest that elimination of HIRA produces a hypertrophic response in skeletal muscle and leaves myofibers susceptible to stress-induced...

We show that the conserved transmembrane Drosophila proteoglycan Kon-tiki (Kon, also known as Perdido) interacts with the αPS2βPS integrin (αPS2 is encoded by inflated and βPS by myospheroid ) to mediate muscle–tendon adhesion. kon and inflated double mutant embryos show a synergistic...
