Expression data from 22 human myotubes

ABSTRACT: Expression data from 22 human myotubes (7 healthy controls, 4 Dysferlinopathy (DYSF), 4 Caveolinopathy 3 (CAV3), 4 Facioscapulohumeral muscular dystrophy(FSHD) and 3 Four and a half LIM 1 protein deficiency FHL1).cDNA microarray data showed that cyclin A1 levels are specifically elevated in FSHD vs. other muscular disorders such as CAV3, DYSF, FHL1 and healthy control. Data could be confirmed with RT-PCR and Western blot analysis showing up-regulated levels of cyclin A1 also on the protein level. Comparison of gene expression among 4 different muscular dystrophies and helathy controls. Looking for genes expression specifically changed (down/upregulated) in FSHD. In these data sheet we include expression data obtained for human cells lines derived from human V.lateralis muscle, shown as mean value. From 59 different expressed genes, Cyclin A1 was selected as a highly overexpressed (28 fold) gene in FSHD if compared to DYSF, CAV3, FHL1 and healyhy controls.

Transcription profiling of human Facioscapulohumeral muscular dystrophy (FSHD) muscle profiles

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.

Whole genome miRNA analysis of in-vitro differentiated myotubes from Emery-Dreifuss Muscular Dystrophy patients.

Project description:Emery-Dreifuss muscular dystrophy (EDMD) is a genetically and clinically variable disorder. Here we performed transcriptome analysis on 10 EDMD patients covering mutations in 7 EDMD-linked genes, compared to 2 healthy controls. Myoblasts were isolated from muscle biopsies and differentiated in-vitro for 6 days. Differentiated myotubes were isolated, total RNA extracted and the small <200 nt fraction sequenced. The genes and mutations included were: patient 1 (TMEM214, p.R179H), patient 2 (PLPP7/NET39, p.M92K), patient 3 (SUN1, p.G68D, p.G388S), patient 4 (SYNE1, p.6869*, p.6869*), patient 5 (EMD, p.S58Sfs*1), patient 6 (FHL1, c.688+1G>A), patient 7 (FHL1, p.C224W), patient 8 (FHL1, p.V280M), patient 9 (LMNA, p.T528K), patient 10 (LMNA, p.R571S).

Expression profiling of 4q-linked and phenotypic FSHD in different steps of myogenic differentiation

Project description:The specific gene(s) responsible for FSHD phenotype have not yet been identified. We used the Human GeneChip Exon 1.0 ST platform to analyze the global gene expression profiles of FSHD-1, FSHD-2 and controls during myogenic differentiation. In this dataset, we include the expression data of human primary myoblasts obtained from three FSHD-1 and two FSHD-2 patients, and three healthy controls (CN). This data are used to evaluate the molecular perturbation of FSHD upon muscle differentiation; we compared patients and CN proliferating myoblasts as well as the corresponding myotubes obtained after 8 days of cell differentiation. 16 expression profiles were generated from 6 different cell types: including myoblasts and myotubes from healthy donors and FSHD-1 and FSHD-2 patients. Gene probesets with P < 0.01 and FC > 2 were selected in FSHD-1 assay, whereas P < 0.001 and FC > 2 were used in FSHD-2, in the attempt to overcame problems due to the small sample size analyzed.

The RNA-binding protein FXR1P regulates cell-cycle progression by modulating the expression of p21/cdkn1a/Cip1/Waf in myoblasts

Project description:The Fragile X Mental Retardation-Related 1 gene (FXR1) belongs to the Fragile X Related gene family, together with FMR1 and FXR2. While inactivation of FMR1 causes Fragile X syndrome, the most common form of inherited mental retardation, inactivation of FXR1 in various animal models suggest a critical role for the RNA-binding protein FXR1P during myogenesis. Seven alternatively spliced FXR1 transcripts have been identified, three of them being muscle-specific. We previously reported a reduction of these isoforms in myoblasts from Fascio Scapulo Humeral Distrophy (FSHD) myopathic patients. However, so far, no mRNA target of FXR1P has been linked to the drastic muscular phenotypes caused by its absence and the exact molecular role of FXR1P in muscular development remains unknown. In the present study, gene expression profiling of C2C12 myoblasts reveals that transcripts involved in cell cycle and muscular development pathways are modulated by Fxr1-depletion. In addition, Fxr1-depletion translates physiologically into a premature cell cycle exit of myoblasts, accompanied by a robust up-regulation of the cyclin-dependant kinase inhibitor p21/Cdkn1a/Waf/Cip1 mRNA. Importantly, we also observe this P21 increase in FSHD human myoblasts depleted in FXR1P muscular isoforms. Our data further indicate that FXR1P muscle-specific isoforms are involved in the post-transcriptional control of p21 mRNA levels via direct interaction with a conserved G-quadruplex structure located in its 3’ untranslated region. This study has crucial implications for the understanding of FXR1P role during myogenesis and the pathophysiology of FSHD. 2 independent experiments performed in a one color design, corresponding to 2 conditions: si-control and si-fxr1, for a total of 4 samples.

Gene expression analysis of FSHD muscle with different MRI pattern

Project description:Objective: to focus on the molecular mechanisms involved in the dystrophic process that leads to selective wasting of single muscles or muscle groups in Facioscapulohumeral muscular dystrophy (FSHD). By muscle MRI we observed that T2-short tau inversion recovery (T2-STIR) sequences identify two different patterns in which each muscle can be found before the irreversible dystrophic alteration, marked as T1-weighted sequence hyperintensity. We studied these conditions in order to obtain further information on the disease pathogenesis. Design: histopathology, gene expression profiling and real time PCR were performed on muscle biopsies. Subjects: muscles (n=8) with different MRI pattern (T1-weighted normal/T2-STIR normal and T1-weighted normal/T2-STIR hyperintense) from FSHD patients. Data were also compared with inflammatory myopathies (n=7), dysferlinopathies (n=4) and normal controls (n=7). Results: myopathic and inflammatory changes characterize T2-STIR hyperintense FSHD muscles, at variance with T2-STIR normal muscles. These two states can be easily distinguished from each other by their transcriptional profile. Comparison of T2-STIR hyperintense FSHD muscles with muscles of inflammatory myopathies shows peculiar changes, although many alterations are shared among these conditions. Conclusions: at the single muscle level, different stages of the disease correspond to the two MRI patterns. T2-STIR hyperintense FSHD muscles are more similar to inflammatory myopathies than to T2-STIR normal FSHD muscles or other muscular dystrophies, and share with them upregulation of genes involved in innate and adaptive immunity. Our data suggest that selective inflammation, together with perturbation in biological processes such as neoangiogenesis, lipid metabolism and adipokine production, may play a role in FSHD progression. 26 samples of human muscle muscle tissue were analysed using the Illumina beadchip technology.
