Abstract:

The spectrin superfamily is a diverse group of proteins variously involved in cross- linking, bundling and binding to the F-actin cytoskeleton. These proteins are modular in nature and interaction with actin occurs, at least in part, via CH domain containing ABDs. The actin binding domains of the spectrin superfamily proteins are all very similar in overall structure however the functions of the individual proteins differ greatly. Utrophin is a member of the spectrin superfamily and has been used extensively to investigate and model the association of actin-binding domains with F- actin; howev

Abstract:

Understanding the regulatory mechanisms controlling utrophin A expression at the sarcolemma of dystrophic muscles will facilitate the development of therapeutic strategies to ameliorate the pathophysiological features of Duchenne Muscular Dystrophy (DMD). The main goal of this study was to characterize the regulation of utrophin A IRES activity using a transgenic mouse model expressing the utrophin A 5’UTR bicistronic reporter and to identify trans-acting factors that could mediate IRES activity and endogenous expression of utrophin A. We found that utrophin A IRES activity is specifically exp

Abstract:

Duchenne Muscular Dystrophy (DMD) is a disorder caused by mutations in the dystrophin gene, preventing the production of the functional dystrophin protein which assures maintenance of the myofiber integrity throughout muscle contraction. A lack of dystrophin results in severe muscle degeneration and regeneration accompanied by a loss of muscle function. Many pre-clinical and clinical studies are focused on developing strategies to counteract the detrimental effects of DMD; however, there is no cure. One such approach consists of upregulating the endogenous protein utrophin A in dystrophic musc

Abstract:

Characterized by the severe progressive wastage of skeletal muscle, Duchenne muscular dystrophy (DMD) is a crippling X-linked recessive disease that is caused by the absence of the protein dystrophin. This thesis aimed to critically evaluate the potential of different therapeutic options to combat this disease. Utrophin is a paralogue of dystrophin. The Fiona mouse is an mdx (dystrophin-deficient) transgenic mouse that overexpresses the full-length utrophin protein in skeletal muscle, and various studies have shown that it does not display a dystrophic phenotype. However, these studies have on

Duchenne muscular dystrophy (DMD) is the most severe and prevalent primary myopathy. This disease is characterized by repeated cycles of muscle fiber degeneration and regeneration with an eventual failure to regenerate leading to the progressive replacement of myofibers by adipose and connective tissues. The genetic defects responsible for DMD are mutations in the short arm of the X chromosome which prevent the production of normal size dystrophin, a large cytoskeletal protein of 427 kDa. In contrast to the homogeneous distribution of dystrophin along muscle fibers, utrophin preferentially acc

Abstract:

Duchenne Muscular Dystrophy (DMD) is an X-linked recessive neuromuscular disorder caused by mutations or deletions in the dystrophin gene. Utrophin up-regulation therapy is among the various therapeutic strategies that are being investigated to treat DMD. In this strategy utrophin, a dystrophin homologue, is up-regulated along the entire length of the sarcolemma to replace the absent dystrophin protein. Previous studies have revealed that utrophin A expression can be controlled by various transcriptional, post-transcriptional and translational mechanisms and pharmacological modulation of these

Abstract:

Duchenne Muscular Dystrophy (DMD) results from the absence of a functional dystrophin protein. Among its possible therapeutic options is the upregulation of dystrophin’s autosomal analogue, utrophin A. This can be achieved by a pharmacologically induced shift towards a slower, more oxidative skeletal muscle phenotype, which has been shown to confer morphological and functional improvements on models of DMD. Whether these improvements are a result of the utrophin A upregulation or other beneficial adaptations associated with the slow, oxidative phenotype, such as improved autophagy, has not bee

Abstract:

Duchenne muscular dystrophy (DMD) is a severe and fatal muscle wasting disease characterized by a high mutation rate in the gene that encodes the membrane-associated protein dystrophin that results in absence of expressed protein. Although the primary genetic defect for DMD is known, the mechanisms that initiate the onset of DMD are not currently understood. This study tested the hypothesis that pathophysiological processes involved in DMD could be identified by the global expression of mRNA in maturing dystrophin- and utrophin-deficient mouse (mdx:utrn-/-) muscles.

Abstract:

Up-regulating utrophin expression at the sarcolemma is thought to be a key therapeutic approach in the fight against DMD. Utrophin was found to have two isoforms which differ mainly in their 5'-untranslated regions. Effects of the utrophin 5'UTRs on reportergene expression in cell culture and muscle injection experiments were assayed by measuring both reporter transcript and protein levels. Translation efficiencies were estimated by calculating transcript to protein ratios. Our results indicate that there is considerable translation inhibition in control muscle.

A Distrofia Muscular de Duchenne (DMD) é uma importante e severa doença músculo degenerativa causada pela mutação do gene da distrofina. Na ausência da distrofina, o sarcolema das células torna-se vulnerável devido a danos induzidos por ciclos contínuos de degeneração e regeneração. Consequentemente, a força muscular diminui e as miofibras são substituídas por tecido fibrótico. Dentre os músculos esqueléticos afetados, o diafragma, destaca-se por ser o principal músculo respiratório acometido na DMD.

The dystrophinopathies are a group of disorders characterised by cellular absence of the membrane stabilising protein, dystrophin. Duchenne muscular dystrophy is the most severe disorder clinically. The deficiency of dystrophin, in the muscular dystrophy X-linked (mdx) mouse causes an elevation in intracellular calcium in cardiac myocytes. Potential mechanisms contributing to increased calcium include enhanced influx, sarcoplasmic reticular calcium release and\or reduced sequestration or sarcolemmal efflux.

Abstract:

Duchenne Muscular Dystrophy (DMD) is an x-linked neuromuscular disease that is caused by an absence of dystrophin protein, rendering skeletal muscle more susceptible to contraction-induced damage. One therapeutic strategy focuses on increasing the expression of endogenous utrophin A, a dystrophin homologue. Interestingly, slow muscle is more resistant to the dystrophic pathology and has increased utrophin A expression (Webster 1998; Gramolini 2001b). These observations led researchers to explore the therapeutic potential of stimulating the slow, oxidative myogenic program (SOMP) in the mdx co

Duchenne Muscular Dystrophy (DMD) is a fatal condition occurring in approximately 1 in 3500 male births and is due to the lack of a protein called dystrophin. Initially DMD was considered a skeletal myopathy, but the pathology and consequences of cardiomyopathy are being increasingly recognised. Fibrosis, resulting from continual cycles of degeneration of the muscle tissues followed by inadequate regeneration of the muscles, is progressive in both cardiac and skeletal dystrophic muscle.
