http://purl.uniprot.org/citations/10381265http://www.w3.org/2000/01/rdf-schema#comment"This study evaluated the influence of dystonia musculorum (dt) mutation, characterized by spinocerebellar fibers degeneration, on cardiac and skeletal muscles: one respiratory (diaphragm, Dia), three masticatory (anterior temporalis, AT; masseter superficialis, MS; and anterior digastric, AD), one hindlimb (soleus, S), tongue (T), and one cardiac (ventricle, V). Body and muscle weight, muscle protein content, and myosin heavy chain (MHC) isoforms relative expression were then compared in dt mutant mice and in normal mice, according to sex. Male body and muscle weight was always greater than that of females, but there was no specific muscle difference in females. dt mutant mice showed a reduced whole body growth but no specific muscle atrophy, as well as a global decrease in muscle protein content that made muscles more fragile. dt mutation induced a global reduction of muscle protein concentration, whereas a general influence of sex could not be disclosed. Concerning MHC relative composition, all the muscles were fast-twitch: Dia, AT, MS, AD, S, and T expressed predominantly the fast type 2 MHC isoforms, whereas V contained only MHC alpha, also a fast MHC. Female muscles were slower than male muscles, except for S, which was faster. However, classification of muscles in terms of shortening velocity was very different in normal males and females. In other respects, dt mutant muscles were slower and consequently more fatigue resistant than normal, except for S, which became faster and less fatigue resistant. dt mutation exhibits then a specific effect on this continually active postural muscle. In the other muscles, global increased fatigue resistance could constitute an adaptive response to work requirements modifications linked to the muscle damage. It should be noted that a developmental MHC (neonatal) was present in female dt AD. Innervation, which influences muscle structure, is altered in dt mutant and could be another causal factor of the fast-to-slow MHC switches. It appears that dystonin, the dt gene product, is very important in maintaining the structural integrity of both cardiac and skeletal muscle and in its absence, the muscle becomes more fragile and is damaged by modified activity."xsd:string
