Frontiers in Physiology, 2022 Dysferlin-null A/J myofibers generate abnormal Ca2+ transients that are slightly reduced in amplitude compared to controls. These are further reduced in amplitude by hypoosmotic shock and often appear as Ca2+ waves (Lukyanenko et al., J. Physiol., 2017).

Skeletal Muscle, 2022 Limb-girdle muscular dystrophy (MD) type 2B (LGMD2B) and Duchenne MD (DMD) are caused by mutations to the Dysferlin and Dystrophin genes, respectively. We have recently demonstrated in typically mild dysferlin- and dystrophin-deficient mouse models that ...

Dysferlinopathy as cause of long-term hyperCKemia with preserved strength [PDF]
Orphanet Journal of Rare DiseasesBackground Dysferlin (DYSF) has a crucial role in sarcolemmal repair. While DYSF mutations commonly manifest as limb-girdle muscular dystrophy (LGMDR2) or distal Miyoshi myopathy, atypical manifestations, such as asymptomatic hyperCKemia and ...

Muscle-specific Ryanodine receptor 1 properties underlie limb-girdle muscular dystrophy 2B/R2 progression [PDF]
Nature CommunicationsRyanodine receptor 1 Ca2+ leak is a signal in skeletal muscle, but chronic leak can underlie pathology. Here we show that in healthy male mouse, limb-girdle muscle presents higher sympathetic input, elevated ryanodine receptor 1 basal phosphorylation ...

Enhancing the Performance of a Blood-Based Diagnostic Screening Tool for Dysferlinopathy: Optimising an Immunoassay Across Continents. [PDF]
Neuropathol Appl NeurobiolWe validated an immunohistochemical method for detecting dysferlin in neutrophils from peripheral blood films (PBFs), offering a minimally invasive alternative to muscle biopsy. In an Indian cohort, the assay showed 100% sensitivity. Specificity depended on sample quality and storage conditions.

The Dysferlin Transcript Containing the Alternative Exon 40a is Essential for Myocyte Functions
Frontiers in Cell and Developmental Biology, 2021 Dysferlinopathies are a group of muscular dystrophies caused by recessive mutations in the DYSF gene encoding the dysferlin protein. Dysferlin is a transmembrane protein involved in several muscle functions like T-tubule maintenance and membrane repair ...

Comprehensive Profiling of Annexins in Neuromuscular Disorders Reveals a Unique Signature in Dysferlinopathy. [PDF]
Eur J NeurolMuscle biopsies from patients across eight neuromuscular disorders and healthy controls were analyzed using immunofluorescence (IF) and immunoblot (WB) to evaluate the expression and localization of seven annexin proteins (A1, A2, A4, A5, A6, A7, A11).

Contribution of dysferlin deficiency to skeletal muscle pathology in asymptomatic and severe dystroglycanopathy models: generation of a new model for Fukuyama congenital muscular dystrophy. [PDF]
PLoS ONE, 2014 Defects in dystroglycan glycosylation are associated with a group of muscular dystrophies, termed dystroglycanopathies, that include Fukuyama congenital muscular dystrophy (FCMD). It is widely believed that abnormal glycosylation of dystroglycan leads to

Proteomic analysis of the dysferlin protein complex unveils its importance for sarcolemmal maintenance and integrity. [PDF]
PLoS ONE, 2010 Dysferlin is critical for repair of muscle membranes after damage. Mutations in dysferlin lead to a progressive muscular dystrophy. Recent studies suggest additional roles for dysferlin.
