Full textThe experimental set-up developed in Toulouse enables to control collisions between a charged thermalised mass-selected free cluster and molecules. Processes of attachement of the molecule onto the cluster and collision induced fragmentation can be studied. In order to better understand the process of attachment of a molecule onto a cluster, we have measured attachment cross-sections of alcohol molecules, methanol and ethanol, onto alcohol clusters. We have observed a similar behaviour as the one observed with water clusters, that is attachment cross-sections that are lower than the geometrical cross-section at small sizes and that converge to this geometrical cross-section at bigger sizes. This behaviour had been assigned to a dynamical effect in the case of water. This dynamical model can be extended with a good qualitative agreement to alcohol clusters. Processes of attachment and fragmentation enable to realise nanocalorimetry measurements. We have determined heat capacities and transition temperatures for protonated water clusters (H2O)nH+. They complete measurements already done for deprotonated water clusters (H2O)n-1OH-. The nature of the phase transition is discussed. The last part of this dissertation concerns collision induced fragmentation for molecules that has some biological interest : protonated uracil, bare or hydrated. Fragmentation pathways of the protonated uracil molecule has been observed. The influence of the number of water molecules on the fragmentation pattern of solvated uracil is linked to the proton affinity of the constituants and to the cluster structure

Full textCongenital myopathies are a heterogeneous group of inherited muscle disorders defined according to the characteristic morphologic lesions observed in the patient muscle biopsies. These lesions could be protein aggregates, cores, and an increased number of central nuclei. The clinical phenotype consists of hypotonia and muscle weakness from infancy, variably associated with other clinical characteristics. There is no specific treatment for these conditions. The congenital myopathies with protein aggregates are a subgroup of congenital myopathies characterized by aggregations of proteins in muscle. Morphological analysis of muscle can distinguish between nonspecific protein aggregations and/or well-defined inclusion bodies, patches or clusters. Mechanisms leading to protein aggregation still remain not completely elucidated. A deep morphological analysis could help in elucidating the events responsible for this phenomenon. Numerous gene loci or gene mutations have been identified in more than 20 forms of congenital myopathies. Nevertheless a large portion of affected patients is not mutated in the known genes. Several unknown entities remain to be discovered. To overcome this gap of knowledge novel approaches are being developed. One of the most promising is next generation or exome sequencing that consists in targeted re-sequencing of all coding sequences within the genome. This tool will surely help the discovery of new genes underlying these rare monogenic diseases. In this study we concentrated in affected by three different forms of congenital myopathies with protein aggregates with or without molecular diagnosis: Reducing Body Myopathy (RBM), Nemaline myopathy (NM) and Cap disease (CD). My activity was focused on three main axes: 1. - Morphological analysis and investigation of pathophysiological mechanisms underlying the appearance of the protein aggregates in patients with RBM and other phenotype associated with mutation in the FHL1 gene. 2. - Clinical and morphological characterisation of families affected by neonatal forms of NM and CD without a genetic characterization. 3. - Functional validation of protein expression of mutations in novel genes identified through next generation sequencing in families presenting with non-diagnosed congenital structural myopathy. In the first part of my study I analysed a group of eighteen patients presenting RBM and other phenotype associated with mutations in the FHL1 gene. FHL1 mutations have been associated with different disorders including reducing body myopathy (RBM), scapuloperoneal syndrome (X-SPM), X-linked myopathy with postural atrophy (XMPMA), Emery-Dreifuss-like muscular dystrophy (EDMD), isolated hypertrophic cardiomyopathy (HCM), and some overlapping conditions. I conducted a detailed histochemical, immunohistochemical, ultrastructural, and immunoelectron microscopy comparative analysis in 14 RBM (group 1), 3 EDMD, and one patient with HCM and muscular hypertrophy (group 2). The analysis of muscle biopsies in group 1 showed reducing bodies (RBs) associated with cytoplasmic bodies as a constant feature. RBs had a prominent FHL1 immunoreactivity. Desmin, alphaB-crystallin and myotilin immunoreactivity was observed surrounding RB. Under electron microscopy (EM), RBs were composed of electron dense tubulofilamentous material that progressively spreads between the myofibrils and around myonuclei. Using immunoelectron microscopy we demonstrated that FHL1 protein is found uniquely inside RBs. Samples from group 2 showed mild dystrophic abnormalities, without RBs. Only minor non-specific myofibrillar abnormalities were observed under EM. Molecular analysis revealed missense mutations in the 2nd FHL1 LIM domain in group 1 patients and ins/del or missense mutations within the 4th FHL1 LIM domain in patients from group 2. With this study I was able to expand the morphological features of RBM, clearly demonstrating the localization of FHL1 in RB, and further illustrating major morphological differences between different FHL1-related myopathies (Malfatti et al. , JNEN 2013). In the second part of the project we performed a deep morphological analysis in our cohort of more than 100 patients presenting a congenital myopathy and we identified homogeneous cohorts of patients presenting neonatal or antenatal onset congenital myopathies with protein aggregates. The exomes of a first group of five patients from four unrelated families presenting with different skeletal muscle pathologies, including a fatal nemaline myopathy with neonatal onset, arthrogryposis and severe respiratory failure, a severe congenital myopathy with internal nuclei and myofibrillar desorganization were sequenced (analysis conducted by Jocelyn Laporte group. ANR Programme Blanc Edition 2011: Identification of novel genes implicated in structural congenital myopathies by exome sequencing to Dr Jocelyn Laporte, IGBMC, UMR7104 INSERM, Illkirch, France, and Dr Norma Beatriz Romero, Unité de Morphologie Neuromusculaire, Institut de Myologie, CHU La Pitié-Salpêtrière). This analysis leads to the identification of autosomal recessive RYR1 mutations in in three patients with different clinical and histological features. RYR1 codes for the skeletal muscle ryanodine receptor, a key player in skeletal muscle excitation-contraction coupling. The two other sporadic patients with fatal neonatal myopathy were found to harbor mutations in NEB, encoding the contractile unit scaffold protein nebulin. We therefore demonstrated that a deep morphological analysis of patients presenting severe neonatal forms of congenital myopathies could help in the orientation toward a specific genetic diagnosis. This study confirmed that congenital myopathies present with broad genetic and phenotypic heterogeneity and that Exome sequencing is a fast and efficient diagnostic tool, especially for large genes (Bohm, Vasli, Malfatti et al. PlosONE 2013). The deep morphological analysis conducted for the identification of homogenous cohorts to be screened by exome analysis allowed the identification of some peculiar and morphologically unique patients. One of this presented a striking combination of cap structures and typical nemaline bodies in his muscle biopsy. This histological association was never reported before. Exome sequencing analysis revealed a recurrent mutation of TPM3 gene. The a-tropomyosin (TM) slow gene, TPM3, codes for a thin filament protein expressed uniquely in type I muscle fibres. The latter belongs to a highly conserved family of actin-binding proteins (TM) that plays important roles in a wide range of cellular process. Tropomyosin is essential for the regulation of muscle contraction. A lack of or an abnormal tropomyosin could explain muscle atrophy and weakness. However the exact mechanisms leading to muscle weakness remains unclear. Mutations in TPM3 have been associated with three distinct and separate histological pattern: nemaline myopathy (NM), myopathy identified as congenital fibre-type disproportion (CFTD) and, more recently, cap disease. These extremely variable histological patterns spanning from protein inclusions (e. G. Rods and caps) to an isolated defect of type 1 fibres, have been encountered only separately. The identification of a patient presenting a unique association of caps and rods allowed us to enlarge the morphological spectrum TPM3 mutated patients, and tightens the histological boundaries of TPM3-related myopathies (Malfatti et al. , Neuromuscular Disorders 2013). The exomes sequencing, successively confirmed by dHPLC/Sanger-sequencing, in a group of fourteen patients with different clinical form of Nemaline myopathies lead to the identifications of autosomal recessive mutations in the nebulin (NEB) gene. To better characterize this group of patients we performed a detailed muscle morphological analysis of this cohort of fourteen NEB-mutated patients to define pathological patterns and clinical-morphological correlations. Four groups were identified according to clinical severity and age at biopsy. Group 1 (n=4) comprises severe/lethal NM and biopsy in first days. Group 2 (n=5) comprehends severe NM and biopsy after one month. Group 3 (n=3) comprises typical NM and biopsy in childhood, and group 4 (n=2) patients with mild NM and biopsy in adulthood. Biopsies underwent histoenzymological, immunohistochemical and ultrastructural analysis. Fiber type distribution, rod characteristics, distribution and localization were investigated. All patients presented NEB mutations consistent with AR inheritance. G1 failed to show type 1 fiber predominance and had scattered squared rods in 1/3 of fibers. Ultrastructural analysis revealed high percentage of fibers with sarcomeric disarray. G2 showed a variable pattern of fiber type distribution spanning from slight type 2 predominance to type 1 uniformity. Rods presented variable distribution and shape. Ultrastructural analysis revealed rare fibers with sarcomeric disarray. In contrast, G3 and G4 presented a homogeneous type 1 uniformity associated with well-delimited subsarcolemmal and/or cytoplasmic elongated rods without sarcomeric alterations. In conclusions we 1) identified an unreported absence of type 1 predominance in muscle biopsy of new-borns patients presenting severe NEB-related NM; 2) suggest a direct correlation between the association of sarcomeric disarray and clinical severity. The presence of well-delimited clusters of rods in milder affected subjects suggests a muscle self-protective response against rod diffusion/propagation (Malfatti et al. In preparation). The third part of the study concern the deep clinical and morphological analysis of family presenting mutations in a new gene identified through Exome sequencing effectuated by the team of Dr Nigel Clarke/Pr Kathrin North, University of Sidney. I performed a peer clinical, morphological, immunofluorescence (IF) and ultrastructural analysis of this family. Furthermore I proceeded to an IF screening using a panel of different antibodies raised against the protein coded by the newly identified gene on muscle biopsy from our cohort of patient (N=20) presenting similar phenotype/morphotype. IF analysis showed an absence of the protein expression on the muscle biospies from mutated patients. On the contrary we failed to show a reduced protein expression in the biopsied muscle of the other patients. The results of these two studies are preliminary confidential data

Full textTubular aggregate myopathy (TAM) is a genetic disorder characterized by tubular aggregates in muscle biopsies of patients. Our team identified for the first time mutations in STIM1 as causative of this disease. STIM1 (stromal interaction molecule 1) is the main calcium (Ca2+) sensor of the endo/sarcoplasmic reticulum (ER/SR). Following Ca2+ depletion of the ER/SR, STIM1 unfolds, oligomerizes and migrates close to the plasma membrane (PM) to activate the Ca2+ channel ORAI1, leading to Ca2+ entry. This mechanism is the «store-operated Ca2+ entry» (SOCE). Several teams report a mutation in STIM1 (p.R304W) leading to TAM associated with other symptoms, described as Stormorken syndrome. Therefore, this work aims to assess and compare the impact of TAM and Stormorken mutations at different stages of the SOCE pathway. We show that TAM and Stormorken mutations lead to an increase expression of the protein, a constitutive STIM1 clustering near the PM, to ORAI1 constitutive recruitment and to the activation of a Ca2+ -dependent pathway: the NFAT pathway
