Dysferlin-deficient immortalized human myoblasts and myotubes as a useful tool to study dysferlinopathy
Dysferlin gene mutations causing LGMD2B are associated with defects in muscle membrane repair. Four stable cell lines have been established from primary human dysferlin-deficient myoblasts harbouring different mutations in the dysferlin gene. We have compared immortalized human myoblasts and myotubes carrying disease-causing mutations in dysferlin to their wild-type counterparts. Fusion of myob...
متن کاملMembrane blebbing as an assessment of functional rescue of dysferlin-deficient human myotubes via nonsense suppression.
Mutations that result in the loss of the protein dysferlin result in defective muscle membrane repair and cause either a form of limb girdle muscular dystrophy (type 2B) or Miyoshi myopathy. Most patients are compound heterozygotes, often carrying one allele with a nonsense mutation. Using dysferlin-deficient mouse and human myocytes, we demonstrated that membrane blebbing in skeletal muscle my...
متن کاملDysferlin and Animal Models for Dysferlinopathy
Dysferlin (DYSF) is involved in the membrane-repair process, in the intracellular vesicle system and in T-tubule development in skeletal muscle. It interacts with mitsugumin 53, annexins, caveolin-3, AHNAK, affixin, S100A10, calpain-3, tubulin and dihydropyridine receptor. Limb-girdle muscular dystrophy 2B (LGMD2B) and Miyoshi myopathy (MM) are muscular dystrophies associated with recessively i...
متن کاملSerum exosomes can restore cellular function in vitro and be used for diagnosis in dysferlinopathy
Purpose: It is challenging to deliver the full-length dysferlin gene or protein to restore cellular functions of dysferlin-deficient (DYSF-/-) myofibres in dysferlinopathy, a disease caused by the absence of dysferlin, which is currently without effective treatment. Exosomes, efficient membranous nanoscale carriers of biological cargoes, could be useful. Experimental design: Myotube- and human ...
متن کاملa frame semantic approach to the study of translating cultural scripts in salingers franny and zooey
the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...
