Project description:Facioscapulohumeral muscular dystrophy (FSHD) is an autosomal dominant disorder linked to contractions of the D4Z4 repeat array in the subtelomeric region of chromosome 4q. By comparing genome-wide gene expression data from muscle biopsies of patients with FSHD to those of 11 other neuromuscular disorders, we intend to identify disease-specific changes which are more likely to be involved in the early stages of the disease progression. The data will help to identify pathological mechanisms involved in FSHD. Experiment Overall Design: Comparison of the profiles of FSHD to 13 other conditions for disease-specific changes. The 13 conditions are NHM (Normal healthy muscle) n=15; JDM (Juvenile dermatomyositis) n=25; HSP (Human spastic paraplegia) n=4; FSHD (facioscapulohumeral dystrophy) unaffected n=5, affected n=9; FKRP (Fukutin related protein deficiency) n=7; ED-L (Emery-Dreifuss muscular dystrophy, lamin A/C deficiency) n=4; ED-E (Emery-Dreifuss muscular dystrophy, emerin deficiency) n=4; DYSF (dysferlinopathy) n=10; DMD (Duchenne Muscular Dystrophy) n=10; CALP (Calpain-3 deficiency) n=10; BMD (Becker Muscular Dystrophy) n=5; AQM (Acute quadriplegic myopathy) n=5; ALS (Amyotrophic lateral sclerosis) n=9.

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:Mutations in the inner nuclear membrane protein emerin cause muscular dystrophy. Current evidence suggests that the muscle wasting is related to defects in muscle progenitor cell differentiation and regeneration. We obtained miRNA and mRNA expression data from wildtype and emerin-null cells and looked at gene expression differences between them. Case vs. control with a technical replicate of each

Project description:Lamins and transmembrane proteins within the nuclear envelope are regulators of nuclear structure and chromatin organization. Nuclear Envelope Transmembrane Protein 39 (Net39) is a muscle-restricted nuclear envelope protein. We show that mice lacking Net39 succumb to severe myopathy and neonatal lethality, with concomitant disruption in nuclear integrity, chromatin accessibility, gene expression and metabolism. These abnormalities resemble those of Emery-Dreifuss muscular dystrophy (EDMD), caused by mutations in A-type Lamins (LMNA) and other genes, like Emerin (EMD). We observe that Net39 is downregulated in EDMD patients, implicating Net39 in the pathogenesis of this disorder. Our findings reveal an intimate role for the nuclear envelope in maintaining muscle chromatin organization, gene expression and function, and highlight the importance of Net39 in these processes and in the molecular etiology of EDMD.

Project description:Lamins and transmembrane proteins within the nuclear envelope regulate nuclear structure and chromatin organization. Nuclear Envelope Transmembrane Protein 39 (Net39) is muscle nuclear envelope protein whose functions in vivo have not been explored. We show that mice lacking Net39 succumb to severe myopathy and juvenile lethality, with concomitant disruption in nuclear integrity, chromatin accessibility, gene expression and metabolism. These abnormalities resemble those of Emery-Dreifuss muscular dystrophy (EDMD), caused by mutations in A-type Lamins (LMNA) and other genes, like Emerin (EMD). We observe that Net39 is downregulated in EDMD patients, implicating Net39 in the pathogenesis of this disorder. Our findings highlight the role of Net39 at the nuclear envelope in maintaining muscle chromatin organization, gene expression and function, and its potential contribution to the molecular etiology of EDMD.
