Mdx mutation

MDX mutant mice do not express dystrophin and are used as a model system for Duchenne Muscular Dystrophy.

mdx/mTR

MDX mice lacking the RNA component of telomerase (mdx/mTR) have shortened telomeres in muscle cells and severe muscular dystrophy that progressively worsens with age.

Obscurin knockout

The obscurin mouse develops a mild skeletal muscle myopathy, characterised by an age-dependent increase in centralised nuclei.

nesprin-1 knockout

Data suggest that Nesprin 1 may be involved in the pathogenesis of Emery-Dreifuss muscular dystrophy.

nebulin knockout

Nebulin is a giant modular sarcomeric protein that has been proposed to play critical roles in myofibrillogenesis, thin filament length regulation, and muscle contraction. Nebulin-deficient mice die within 8-11 d after birth, with symptoms including decreased milk intake and muscle weakness.

Cypher knockout

Cypher is a member of a recently emerging family of proteins containing a PDZ domain at their NH(2) terminus and one or three LIM domains at their COOH terminus. Cypher knockout mice display a severe form of congenital myopathy and die postnatally from functional failure in multiple striated muscles.

FHL1 knockout

Recent human genetic studies have provided evidences that sporadic or inherited missense mutations in four-and-a-half LIM domain protein 1 (FHL1), resulting in alterations in FHL1 protein expression, are associated with rare congenital myopathies, including reducing body myopathy and Emery-Dreifuss muscular dystrophy.

Net25 knockout

6 nuclear envelope transmembrane proteins (NETs) are predicted to have important functions in muscle development and/or maintenance from their expression patterns during myoblast differentiation and in mouse tissues. Mutations in certain NETs cause muscular dystrophies and other disorders, but the disease mechanisms remain unclear.

SP-C/TNF-alpha over- expressing mouse

SP-C/TNF-alpha mice exhibited increased levels of TNF-alpha in the circulation and increased endogenous TNF-alpha expression in skeletal muscle, potentially reflecting an amplificatory response to circulating TNF-alpha. Decreased muscle and body weights observed in SP-C/TNF-alpha mice were indicative of muscle wasting.
