Full textMuscle microvasculature is often considered solely as a source of nutrients and oxygen for growing muscle cells and seems to be stereotypically conserved between human and mouse. The adult normal muscle microvascular unit is formed of 6–8 capillaries. In Gitiaux, et al. (2013) we show that microvascular unit organization and size are strikingly similar in human and small animals. In the adult skeletal muscle, the majority of satellite cells are close neighbors of pericytes and some of them are probably able to establish temporary direct contacts with pericytes. During post-natal development, in human and mice, pericytes and satellite cells become progressively closer. In vitro, endothelial cells induce satellite cell activation and proliferation through Angpt-2 and PDGF-BB, while pericytes induce quiescence through Angpt-1 and differentiation of satellite cells through IGF-1. These effects are confirmed by in vivo experiments using Tg:NG2Cre/+::R26RiDTR, Tg:NG2Cre/+::IGF1del/+ and Tg:TNAPCreERT2/+::Angpt1del/+ mice, which exhibit muscle hypotrophy and satellite cell activation. All these results support the emerging concept that “stem cells support other stem cells”

Full textThe imprinted H19 gene is highly expressed during embryonic development. H19 is fully repressed after birth in all tissues, with the exception of skeletal muscle, and especially of the muscle stem cells: the satellite cells. The aim of my thesis was to define the function of the H19 gene in the satellite cells establishment and function during adult myogenesis. Using loss-of-function H19∆3 mice, the laboratory had shown that the H19 gene was able to modulate the expression of several genes belonging to an imprinted gene network (IGN) in the embryonic muscle. During my thesis, I studied the muscle phenotype of these adult mice, which present both fiber hyperplasia and hypertrophy. This phenotype is accompanied by an important reduction of the satellite cell number, probably due to a delay in their entry into quiescence. Unexpectedly, despite the reduction in the number of satellite cells in mutant mice, the self-renewal capacity of the satellite cells is fully retained. In addition, we observe a better regeneration potential of the mutant muscles compared with wt muscles. This is accompanied by the enhanced expression of several genes from the IGN. These results indicate that H19 gene can modulate IGN gene expression both during embryogenesis and after birth, in adult myogenesis

Full textThe decline in muscle mass during physiological aging, called sarcopenia, is a progressive phenomenon whose consequences on health can be disastrous. Muscle stem cells, also called satellite cells, ensure muscle homeostasis. They gradually lose the ability to regenerate damaged tissue with age. The precise mechanisms of this degenerative process are still poorly understood but it seems to imply alterations of the epigenetic marks regulating gene expression in satellite cells.This thesis has focused on the mechanisms leading to this progressive incapacity of the satellite cells to make new muscle fibers with age. The work is divided in two major parts: the role of UTX on the expression of muscle genes and more particularly their splicing and the consequences of the alterations in the trimethylation level of histone H3 lysine 27 (H3K27me3) regulated by UTX in the satellite cells of so-called "geriatric" mice.We have thus demonstrated that UTX is necessary at different stages of the differentiation process to activate gene transcription and alternative splicing.In elderly individuals, the expression of UTX is altered, resulting in modifications of the epigenetic profile of the satellite cells and a disruption of their gene expression program. Finally, preliminary results suggest that UTX also participates in the "chronic inflammatory syndrome" observed in elderly mice, regulating the expression of pro-inflammatory factors such as IL-6.This work allowed us to highlight the role of UTX at different levels of regulation of gene expression in muscle cells, explaining at least in part the defects of regeneration related to aging
Mougeolle, Alexis. "Effet du stress oxydant sur les cavéoles dans les cellules musculaires squelettiques." Thesis, Bordeaux, 2014. http://www.theses.fr/2014BORD0298/document.
Full textSarcopenia is an age-related degenerative disease which is characterized by a progressive and involuntary loss of muscle mass and strength. It is accompanied by an impairment of muscle regeneration and accumulation of reactive oxygen species. Caveolae are invaginations of the plasma membrane. In muscle, they play a role in the differentiation of satellite cells and in maintaining the contractile unit of the differentiated skeletal muscle. Some myopathies are resulting from the absence of caveolae in muscle. Caveolae are also involved in mediating signals related to the regulation of oxidative stress. To better understand the mechanisms involved in the development of sarcopenia, we investigated here the relationship between oxidative stress and caveolae. Mouse muscle cells were treated with H2O2 and decreased levels of caveolin-1 and -3 were demonstrated in myoblasts and myotubes, respectively. It therefore appears that caveolae constituent proteins are actually sensitive to oxidative stress in muscle cells. In the presence of H2O2, caveolae functions (endocytosis and resistance to mechanical stress) were also significantly degraded in myoblasts. Altogether, these data suggest that oxidative stress would affect caveolae, which could have consequences on regeneration and maintenance of muscle integrity during aging

Full textIn this thesis, we evaluated the late effects of neonatal undernutrition on the expression/production of fusion molecules and transcriptional factors in alveolar macrophages and skeletal muscle cells. Thirty-six male Wistar rats were suckled by mothers fed diets containing 17% casein, control group (C) or 8% casein, undernourished group (UN) during lactation. After weaning, all animals received a normoproteic diet (Labina or Teklad Global), at 42 days (n=12), 60 days (n=12) and 90 days (n=12). Half of these animals (n=18) were submitted to a tracheostomy for the removal of bronchoalveolar lavage and subsequent culture of alveolar macrophages for 4 days. In the other half (n = 18), all muscles of both legs were removed and the skeletal muscle cells cultured for 10 days. This resulted in two original articles. The first of these, entitled “Long-term effects of a neonatal low-protein diet in rats on the number of macrophages in culture and the expression/production of fusion proteins”, allowed us to observe that undernutrition during lactation altered the number of macrophages in culture and the production of fusion proteins in young and adult rats, but did not modify the expression of cadherin adhesion molecules. The second article, entitled “Effect of a neonatal low-protein diet on the morphology of myotubes in culture and the expression of key proteins that regulate myogenesis in young and adult rats”, demonstrated that neonatal undernutrition did not modify the expression of key proteins of the myogenic process but altered the morphology and reduced the number of myotubes in culture from 60-day-old rats. In conclusion, neonatal undernutrition caused sequelae in young and adult organisms, even after nutritional recovery. These changes were evidenced in the development of alveolar macrophages in culture and myogenesis
