Project description:Dysferlin is expressed in skeletal and cardiac muscle. However, dysferlin deficiency, namely limb girdle muscular dystrophy 2B (LGMD2B) and Myoshi myopathy, results in skeletal muscle weakness and spares the heart. This dichotomy could be caused by differential regulation of protective mechanisms. Therefore, we compared intraindividual mRNA expression profiles between cardiac and skeletal muscle in dysferlin-deficient SJL/J mice and normal C57BL/6 mice. Experiment Overall Design: 20 chips were analyzed. They represent 4 groups of 5 replicates each. Experiment Overall Design: The 4 groups are cardiac (LV) and skeletal muscle of normal and dysferlin deficient mice. Experiment Overall Design: Tissues from normal mice are the controls in comparison to tissues of dysferlin deficient mice.

Project description:Pompe disease is a Lysosomal glycogen storage disorder due to the deficiency of acid alpha glucosidase. The enzyme degrades glycogen to glucose and its deficiency results in progressive enlargement of glycogen-filled lysosomes in multiple tissues with skeletal and cardiac muscle most severely affected clinically. Clinical spectrum ranges from most severe infantile cardiomegally and skeletal muscle myopathy to milder late onset forms with only skeletal muscle pathology. The currently available enzyme replacement therapy has only limited effect in skeletal muscle. Here we use RNA sequencing of therapy-resistant skeletal muscle (white part of gastrocnemius muscle) to identify the differencies between the diseased and healthy muscle. Total RNA was obtained from gastrocnemius muscle (white part) of acid alpha glucosidase knock-out and wild-type mice.

Project description:Summary: Genetic disorders of muscle cause muscular dystrophy, and are some of the most common inborn errors of metabolism. Muscle also rapidly remodels in response to training and innervation. Muscle weakness and wasting is important in such conditions as aging, critical care medicine, space flight, and diabetes. Finally, muscle can also be used to investigate systemic defects, and the compensatory mechansisms invoked by cells to overcome biochemical and genetic abnormalities. Here, we provide a 13 group data set for comparative profiling of human skeletal muscle. Groups studied are: Normal human skeletal muscle, Acute quadriplegic myopathy (AQM; critical care myopathy), Juvenile dermatomyositis (JDM), Amyotophic lateral sclerosis (ALS), spastic paraplegia (SPG4; spastin), Fascioscapulohumeral muscular dystrophy (FSHD), Emery Dreifuss muscular dystrophy (both X linked recessive emerin form; autosomal dominant Lamin A/C form), Becker muscular dystrophy (partial loss of dystrophin), Duchenne muscular dystrophy (complete loss of dystrophin), Calpain 3 (LGMD2A), dysferlin (LGMD2B), FKRP (glycosylation defect; homozygous for a missense mutation). U133A and U133B microarrays are both available. Hypothesis: This data set is able to define biochemical pathways that are either specific for a disease group, or shared between disease groups. For example, this data set has been used to determine the biochemical pathway perturbations that are shared between the two different types of Emery Dreifuss muscular dystrophy (lamin A/C, and emerin). Specific Aim: The specific aim of this study is to determine the disease-specific transcriptional profiles of these 13 patient groups, and to determine if these expression fingerprints provide either pathophysiology or diagnostic information for these diseases. Some of the groups in this large data set have been reported previously using U95A microarrays, as follows: Juvenile dermatomyositis (JDM): Tezak Z, Hoffman EP, Lutz JL, Fedczyna TO, Stephan D, Bremer EG, Krasnoselska-Riz I, Kumar A, Pachman LM.

Project description:Rhabdomyosarcomas (RSCs) are skeletal muscle neoplasms found in humans and domestic mammals. The A/J inbred strain developed a high frequency of RSC by 20 months of age while BALB/cJ and BALB/cByJ also develop RSC but less frequently. These neoplasms affected skeletal muscle surrounding either the axial or proximal appendicular skeleton and were characterized by pleomorphic cells with abundant eosinophilic cytoplasm, multiple nuclei, and cross striations that invaded locally. The diagnosis was confirmed by detection of alpha-sarcomeric actin and myogenin in the neoplastic cells using immunocytochemistry. The A/J strain, but not the related BALB/c substrains, is also characterised by a progressive muscular dystrophy homologous to limb-girdle muscular dystrophy type 2B. The association between the development of RSC in similar muscle groups to those most severely affected by the progressive muscular dystrophy suggested that these neoplasms developed from abnormal regeneration of the skeletal muscle exacerbated by the dysferlin mutation. Transcriptome analyses revealed marked downregulation of genes in muscular development and function signaling networks. Non-synonymous coding SNPs were found in Myl1, Abra, Sgca, Ttn, and Kcnj12 suggesting these may be important in the pathogenesis of RSC. These studies suggest that A strains of mice can be useful models for dissecting the molecular genetic basis for development, progression, and ultimately for testing novel anticancer therapeutic agents dealing with rhabdomyosarcoma. Total RNA obtained from skeletal muscle samples from neoplastic and non-neoplastic tissues. Four rhabdomyosarcomas (~450 day old male A/J mice) and 8 nonneoplastic skeletal muscle samples (425-550 day old male A/J mice) were used

Project description:We have performed expression profiling to define the molecular changes in dysferlinopathy using a novel dedicated microarray platform made with 3’-end skeletal muscle cDNAs. Eight dysferlinopathy patients, defined by western blot, immunohistochemistry and mutation analysis, were investigated with this technology. The expression profiles of patients with different clinical traits were independently obtained and hierarchical clustering was applied to discover patient-specific gene variations. MHC class I genes and genes involved in protein biosynthesis were up-regulated in relation to muscle histopathological features. Conversely, the expression of genes codifying the sarcomeric proteins titin, nebulin and telethonin was down-regulated. Neither calpain-3 nor caveolin, a sarcolemmal protein interacting with dysferlin, was consistently reduced. There was a major up-regulation of proteins interacting with calcium, namely S100 calcium-binding proteins and sarcolipin, a sarcoplasmic calcium regulator.
