Description
Mice homozygous for this targeted mutation are viable, fertile and show a normal growth rate. Mice develop a slowly progressive muscular dystrophy. By the age of 2 months, a few individual necrotic and centrally nucleated fibers can be detected throughout the muscle; the number increases with age. By 8 months, the muscle develops all of the pathological characteristics of muscular dystrophy (e.g. regenerating fibers, split fibers, muscle necrosis with macrophage infiltration and fat replacement). The severity of the pathology varies in different muscles. Muscle fibers are defective in Ca2+-dependent sarcolemma resealing/repair. No protein product from the targeted gene is detected in skeletal muscle microsomes. This mutant mouse strain represents a model that may be useful in studies of muscle disease and repair.

Development
A targeting vector containing a neomycin resistance gene was use to replace a 12 kb region containing the last three coding exons of the gene, including the exons coding for the transmembrane domain. The construct was electroporated into (129X1/SvJ x 129S1/Sv)F1-Kitl+-derived R1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts. This strain was backcrossed to C57BL/6 for seven generations by the donating laboratory.

        involves: 129S1/Sv * 129X1/SvJ * C57BL/6
  • muscle phenotype
  • abnormal muscle regeneration
    • in response to sarcolemma injuries, mutant skeletal muscle fibers display sub-sarcolemmal vesicle accumulations, whereas wild-type damaged fibers exhibit only dysferlin-enriched membrane patches   (MGI Ref ID J:83126)
    • unlike wild-type muscle fibres, mutant skeletal muscle fibres are defective in Ca2+-dependent sarcolemma resealing, indicating a disruption of the muscle membrane repair machinery   (MGI Ref ID J:83126)
  • abnormal sarcolemma morphology
    • plasma membrane disruptions are identified with Evans blue by 8 months of age   (MGI Ref ID J:83126)
    • however, minimal sarcolemma damage is detected in mutant muscle after exercise, indicating the presence of a functional dystrophin-glycoprotein complex (DGC) and stable sarcolemma   (MGI Ref ID J:83126)
  • centrally nucleated skeletal muscle fibers
    • ~10% of all fibers in mutant skeletal muscle are centrally nucleated by 2 months of age, 20% by 4 months of age, and 48% and 65% by 8 and 10 months, respectively   (MGI Ref ID J:83126)
  • dystrophic muscle
    • homozygotes develop a slowly progressive muscular dystrophy at the level of single muscle fibers, as evidenced by the presence of individual Evans-blue positive fibers   (MGI Ref ID J:83126)
    • the % of centrally nucleated fibers increases with age, with a few individual necrotic and centrally nucleated fibers first evident at 2 months of age   (MGI Ref ID J:83126)
    • by 8 months of age, dystrophic skeletal muscle exhibits regenerating fibers, split fibers, and muscle necrosis with macrophage infiltration, and fat replacement   (MGI Ref ID J:83126)
    • the severity of muscle pathology varies in different skeletal muscles   (MGI Ref ID J:83126)
  • increased variability of skeletal muscle fiber size
    • at 9 months of age, a significantly greater muscle fiber size variation is noted in mutant skeletal muscle than in wild-type muscle   (MGI Ref ID J:83126)
  • skeletal muscle fiber degeneration
    • active skeletal muscle regeneration occurs in response to muscle degeneration, as evidenced by the presence of centrally nucleated skeletal muscle fibers and increased variability in fiber size   (MGI Ref ID J:83126)
  • skeletal muscle fiber necrosis
    • significant skeletal muscle necrosis with macrophage infiltration and fat replacement is evident by 8 months of age   (MGI Ref ID J:83126)
  • homeostasis/metabolism phenotype
  • increased circulating creatine kinase level
    • homozygotes exhibit a several-fold increase in serum creatine kinase levels relative to wild-type mice   (MGI Ref ID J:83126)

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
