Skeletal muscle is highly sensitive to mutations in genes that participate in membrane stability and cellular attachment, which often leads to muscular dystrophy. Here we show that Thrombospondin-4 (Thbs4) regulates skeletal muscle integrity and its susceptibility to muscular dystrophy through organization of membrane attachment complexes. Loss of the Thbs4 gene causes spontaneous dystrophic ch...

Ribosome concentration, ribosome distribution on sucrose density gradients, and in-vitro ribosomal amino-acid incorporation (noncollagen and collagen synthesis) were studied in muscle biopsy samples obtained from 30 patients with Duchenne muscular dystrophy, seven patients with Becker muscular dystrophy, and 10 with facioscapulohumeral muscular dystrophy. Ribosome concentration was normal in Du...

Abstract Myotonic Dystrophy(MD) is an autosomal dominant genetic condition affecting the musculoskeletal system. Recurrent acute pancreatitis(RAP) a frequent presentation in emergency surgical scenario with two or more episodes of established pancreatitis separated by minimum 3 month periods. We report here case patient presenting background Dystrophy third episode RAP. Diagnostic work up led t...

Abstract The study has developed a model splicing construct assay system based on misregulation, one of the major molecular features associated with myotonic dystrophy. double reporters for intron 2 in chloride channel (CLCN1). CLCN1 transgene was used to transfect wild type and DM fibroblast cell lines clones generated showed that it enabled quantification efficiency construct. Validation fibr...

PURPOSE To determine the extracellular matrix proteins involved in the formation of human granular and lattice type I corneal stromal dystrophies, the expression patterns of fibrillin-2, tenascin-C, matrilin-2, and matrilin-4 were compared in human corneal stromal dystrophy samples. METHODS Ten cases of granular dystrophy, 7 cases of lattice dystrophy, and 6 normal corneal buttons collected d...

BACKGROUND Studies with nondepolarizing neuromuscular blocking agents showed a delayed onset and prolonged recovery in patients with Duchenne muscular dystrophy. The objective of this study was to investigate if these alterations depend on disease progression. METHODS The authors studied 11 children (6-9 yr) with moderate Duchenne muscular dystrophy, 11 adolescents (12-16 yr) with advanced Du...

OBJECTIVE To investigate the potential role of apoptosis in the pathogenesis of Fuchs endothelial dystrophy of the cornea. METHODS Twenty-one corneal buttons from patients with Fuchs dystrophy and 15 control corneas were studied. Apoptosis was assessed by the in situ end-labeling of double-stranded DNA breaks, and by immunohistochemical characterization of cellular markers associated with apo...

Genetic defects in a number of components of the dystrophin-glycoprotein complex (DGC) lead to distinct forms of muscular dystrophy. However, little is known about how alterations in the DGC are manifested in the pathophysiology present in dystrophic muscle tissue. One hypothesis is that the DGC protects the sarcolemma from contraction-induced damage. Using tracer molecules, we compared sarcole...

OBJECTIVE To determine the number of employed people in a group of patients with neuromuscular diseases and in 3 separate subgroups (facioscapulo-humeral dystrophy, hereditary motor and sensory neuropathy, and myotonic dystrophy) to investigate any differences in employment status between the patient groups, and to identify factors related to employment status. DESIGN Cross-sectional study. ...
