Objectif(s) : My lab has a long-standing interest in understanding the regulatory networks of developmental and adult myogenesis, with a specific focus on muscle stem cells (termed satellite cells). Through large-scale screens we have identified the transcriptional and epigenetic shift that is manifested at the quiescence-to-activation switch. We are following up on several factors and pathways that regulate quiescence, activation, differentiation, self-renewal, and the epigenetic landscape of satellite cells. Furthermore, we are investigating the adaptive response of satellite cells to environmental stress. Finally, we have developed a novel protocol that permits the isolation of truly quiescent satellite cells, avoiding the artefacts introduced by current isolation protocols. Using this protocol we are launching a series of high throughput and single cells experiments to uncover the major players of the quiescence and activation networks. Elucidating the networks that command satellite cell quiescence and activation is a major challenge and a requirement to comprehend the remarkable regenerative capacity that muscle displays.

Objectif(s) : Causes of many myopathies remain unresolved and succesfull treatment strategies are scarce. A prime example of an unresolved, but life-threatening muscle disease is nemaline myopathy. In muscle cells, the contractile machinery is arranged into sarcomeres, a system of interdigitating thin and thick filaments. Where the thick filament is mainly composed of myosin, the thin filament is composed of an actin backbone decorated with regulatory proteins, such as troponin, tropomyosin and the giant protein nebulin. It is this thin filament that is implicated in nemaline myopathy. Mutations in twelve genes have been indicated to play a role, all genes encoding proteins that are either components of the thin filament or are thought to contribute to stability or turnover of thin filament proteins. It is therefore, that nemaline myopathy is considered a ‘thin filament myopathy’. These mutations in thin filament proteins, together with the crucial role of the thin filament in muscle function, raise the question: is the functioning of the thin filament affected in nemaline myopathy, and if so, how ? Only in recent years this question has been addressed, and many important ones have yet to be answered. Understanding the genotype-phenotype correlations in nemaline myopathy is important, as it allows for the development of genotype-targeted treatment strategies.

Camille JANUEL (Corbeil-Essonne, France)

Objectif(s) : Spinal muscular atrophy (SMA) is the most common genetic cause of infant mortality characterized by the specific degeneration of lower motor neurons (MNs) in the spinal cord, leading to progressive paralysis and muscle atrophy. SMA etiology relates to insufficient amount of SMN protein, which results from mutations in the survival motor neuron 1 (SMN1) gene. Despite the ubiquitous expression of SMN protein, it is still unclear why MNs are one of the most affected cell types. Understanding this specific cellular tropism is critical but requires access to the relevant cell type. MNs from mouse are difficult to isolate and are obviously impossible to access from human. The ability to reprogram somatic cells into human induced pluripotent stem cells (hiPSC) offers a unique opportunity to access normal and pathological bona fide neuronal populations in sufficient quantities for systematic molecular and cellular analysis. In this present study, we demonstrated that the reduced expression of SMN led to a decreased survival of hiPSC-derived motoneurons rather than a defect in their generation, phenotype that can be rescued by the reintroduction of SMN protein. We identified that this phenotype can be rescued by kenpaullone, an inhibitor of several CKDs (cyclin-dependent kinases) as well as GSK-3b, likely through a CDK independent mechanism. By a transcriptomic approach on SMA hiPSC-derived MNs, we identified SMA-specific changes in early MNs that include genes involved in synaptic plasticity. Interestingly, these genetic defects were partially rescued by kenpaullone treatment. These findings suggest that alteration in synaptic organization might be a new therapeutic target for SMA. Altogether, our results demonstrate the potential offered by human pluripotent stem cells to shed light on the cellular and molecular bases of selective motor neuron vulnerability in SMA condition.

Objectif(s) : Stem cells have been suggested as a possible treatment for muscular dystrophies, such as Duchenne muscular dystrophy (DMD). This was based on work using pre-clinical animal models of DMD, showing that different muscle stem cells contributed to regenerated muscle fibres following either their local or systemic delivery. The muscle fibres of donor origin expressed dystrophin, which should protect them from undergoing further rounds of necrosis and regeneration. As well as contributing to regenerated muscle fibres, some types of donor stem cell also functionally reconstituted the skeletal muscle stem cell pool, thus providing long-term benefit. The first clinical trials of stem cells in DMD, performed in the 1990s, involved the intra-muscular transplantation of myoblasts derived from normal donors. The outcomes of these and subsequent trials have been disappointing, with little evidence of donor cell engraftment and no significant functional benefit. But findings from these trials and from stem cell transplantation experiments in mouse models, highlight several major hurdles that need to be overcome. The majority of cells die very rapidly following their intra-muscular transplantation and the minority that survive may not proliferate extensively. Also, the transplanted cells do not migrate far from the site of injection. Systemic transplantation of stem cells would be required to treat patient muscles body-wide, but ensuring that they reach, enter and contribute to muscle fibres within downstream muscles are major obstacles. Immune rejection of either the transplanted cells, or the donor-derived muscle fibres that express de novo dystrophin, is another potential problem. This might be circumvented by cell-mediated gene therapy of autologous stem cells, or by genetically-correcting autologous stem cells. Generating sufficient cells for either local or systemic delivery is a further issue. Expansion of skeletal muscle stem cel

Jean-Louis BESSEREAU (Lyon, France) 12h00 • S10-03 • Sarcolemmal membrane repair activated by conserved intracellular signaling responses can compensate for membrane fragility in muscular dystrophy > N. Noah WEISLEDER (Columbus, USA)

Objectif(s) : A conserved plasma membrane repair mechanism exists to counteract sarcolemmal membrane damage in muscle cells, restore membrane barrier function, and maintain muscle cell homeostasis. Membrane damage induced by various insults requires an effective repair mechanism and any disruption of the process gives rise to several pathophysiological states. Previous studies indicate that compromised repair capacity in striated muscle can lead to muscular dystrophy and that increasing membrane repair capacity can have therapeutic effects in animal models of muscular dystrophy. This membrane repair response can involve various cellular mechanisms to repair large disruptions in the sarcolemmal membrane, including activation of signaling pathways that trigger vesicular trafficking to the site of injury followed by vesicular fusion with the damaged portion of the membrane to patch the membrane disruption. Multiple proteins, including dysferlin, TRIM72/MG53, and various annexins, participate in this repair response. Numerous studies have shown that several aspects of vesicle trafficking are dependent on the phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K) signaling pathway. In this study, membrane repair assays on skeletal muscle and non-muscle cell lines demonstrated that the membrane repair process is dependent on activation of the PI3K signaling axis through the downstream target Akt1. This signaling response facilitates the function of TRIM72/MG53 in membrane repair since blocking PI3K or Akt1 minimizes the elevated membrane repair produced by TRIM72/MG53 overexpression. One mechanism found to increase membrane repair following TRIM72/MG53 overexpression or PI3K/Akt1 activation is elevated exocytotic and endocytotic activity. Further, multi-photon microscopy studies indicate that the PI3K/Akt1 pathway is relevant to membrane repair in isolated mouse muscle bundles injured because PI3K or Akt1 inhibition prevents membrane resealing.

16h30 • S14-01 • Regulation of the mouse skeletal muscle stem cell niche during homeostasis and regeneration > S. Shahragim TAJBAKHSH (Paris, France)

Objectif(s) : Regulation of skeletal muscle stem cells during homeostasis and regeneration involves the interplay between extrinsic and intrinsic cues. In a series of studies, we investigated Notch as a key mediator of muscle stem cell stability and fate through extrinsic regulation of extracellular matrix, and internal regulation of cell migration via the mirtron mir708. Using static and live imaging, these observations led us to propose a two-step mechanism where the final mitosis before cellular quiescence, and cell migration, are negotiated before niche occupancy. Using cell lineage reporter mice, our data show that muscle stem cells exit from the cell cycle first, continue to migrate, then arrest and occupy the niche under the regulation of two Notch mediated axes. In parallel, we developed a novel in vivo clonal cell lineage method using Pax7 reporter mice to mark all muscle stem cells, and combined this with transcription factor readouts (Pax7, MyoD and Myogenin as stem and differentiating markers) to assess division asymmetry. Our ex vivo live imaging of artificial niches on fibronectin coated micropatterns, and in vivo clonal analyses show for the first time that asymmetric and symmetric cell divisions both contribute to the self-renewal process in vivo. This division asymmetry was examined in more detail using H3.1-SNAP transgenic mice that we generated that allow tracking of old and new histone pools. Using this transgenic in combination with clonal lineage studies in vivo, we show that in contrast to the fly germ line where this histone variant was reported to segregate asymmetrically, we observe symmetric distribution of H3.1 during muscle stem cell asymmetric cell divisions. Taken together, we show that muscle stem cell regulation is dynamic during homeostasis and regeneration and we propose a model of how the asymmetry apparatus engages in cell fate decisions during muscle stem cell self-renewal and differentiation during tissue regeneration.

Objectif(s) : Oligonucleotide therapies for neuromuscular disease Gene based therapeutic interventions have the potential to transform the treatment landscape for neuromuscular diseases. After more than a decade of effort, significant progress has been made in the development of first generation oligonucleotide therapies for Duchenne muscular dystrophy (DMD) and spinal muscular atrophy (SMA). These oligonucleotide drugs modulate target gene splicing in order to correct the underlying genetic defect and restore expression of essential proteins. First generation oligonucleotides, while demonstrating proof-of-principle, suffer from the limitation of inadequate tissue and cell delivery - the major barrier to the development of potent, disease modifying oligonucleotide interventions. The goal of second generation oligonucleotides is to overcome the barrier of intracellular delivery either by the development of novel oligonucleotide backbone chemistries with improved delivery properties and/or by exploitation of delivery technologies which may be coupled with oligonucleotide drugs.

11h00 • S16-01 • Facioscapulohumeral muscular dystrophy > S. Silvere VAN DER MAAREL (Leiden, Netherlands)

Objectif(s) : Facioscapulohumeral dystrophy (FSHD) is one of the most common inherited myopathies clinically defined by progressive weakness and wasting of the facial, shoulder girdle and upper arm muscles. With disease progression, other muscles may become affected too. Non-muscular features are rare, and often subclinical. FSHD is associated with inappropriate expression of the cleavage stage transcription factor DUX4 as a consequence of partial chromatin relaxation of the D4Z4 repeat on chromosome 4q35. The D4Z4 repeat varies between 8-100 units in the population and adopts a repressive chromatin structure in somatic cells such as skeletal muscle. As a result of D4Z4 repeat contractions to a size of 1-10 units (FSHD1), or mutations in chromatin modifiers that facilitate a repressive D4Z4 chromatin structure in somatic cells (FSHD2), in FSHD muscle the D4Z4 chromatin structure is more relaxed. This causes derepression of the D4Z4-embedded DUX4 retrogene in skeletal muscle, which, in turn, initiates a cascade of events leading to muscle damage. Most FSHD2 patients have a heterozygous mutation in SMCHD1 encoding a chromatin repressor that binds to D4Z4. Reduced SMCHD1 repressor activity at D4Z4 causes DUX4 expression in skeletal muscle. SMCHD1 was also identified as a modifier for FSHD1 and a recent FSHD population study suggests that, rather than separate entities, FSHD1 and FSHD2 form a continuum in which genetic (the repeat size) and epigenetic (the activity of D4Z4 chromatin modifiers) synergistically contribute to DUX4 derepression and disease presentation. Only a minority of myonuclei express DUX4 in FSHD muscle cell cultures. How such sporadic expression leads to severe muscle wasting in FSHD largely remains unclear. Indeed transcriptome studies in FSHD have systematically been challenged by the sporadic nature of DUX4 expression, with the majority of non-affected cells masking the consequences of the presence of DUX4. Taking advantage of single-cell RNA-sequencing, comb

Objectif(s) : Skeletal muscle is an archetypal adult stem cell model, in which maintenance, growth and repair of functionally specialised post-mitotic cells is achieved by recruitment of undifferentiated precursors. For the past 18 years, my core research has been directed at understanding how muscle stem cells are regulated in healthy, aged and diseased skeletal muscle. The functional unit of skeletal muscle is the myofibre: a giant syncytial cell maintained by hundreds of post-mitotic myonuclei. The routine needs for myonuclear homeostasis, together with the more sporadic demands for hypertrophy and repair, are performed by muscle satellite cells. These resident stem cells are normally mitotically quiescent in mature muscle, and so must first be activated to undergo extensive proliferation to generate myoblasts that eventually differentiate to provide new myonuclei. The main themes of the group at King’s College London currently include investigating the transcriptional and signaling control of satellite cell activation and cell fate choice, and examining pathomechanisms and potential therapies for Emery-Dreifuss muscular dystrophy, Fascioscapulohumeral muscular dystrophy and rhabdomyosarcoma.
