|title=Transgenic overexpression of [[ADAM12]] suppresses muscle regeneration and aggravates dystrophy in aged mdx mice.

|abstract=Muscular dystrophies are characterized by insufficient restoration and gradual replacement of the skeletal muscle by fat and connective tissue. [[ADAM12]] has previously been shown to alleviate the pathology of young dystrophin-deficient mdx mice, a model for Duchenne muscular dystrophy. The observed effect of [[ADAM12]] was suggested to be mediated via a membrane-stabilizing up-regulation of utrophin, alpha7B integrin, and dystroglycans. Ectopic [[ADAM12]] expression in normal mouse skeletal muscle also improved regeneration after freeze injury, presumably by the same mechanism. Hence, it was suggested that [[ADAM12]] could be a candidate for nonreplacement gene therapy of Duchenne muscular dystrophy. We therefore evaluated the long-term effect of [[ADAM12]] overexpression in muscle. Surprisingly, we observed loss of skeletal muscle and accelerated fibrosis and adipogenesis in 1-year-old mdx mice transgenically overexpressing [[ADAM12]] ([[ADAM12]]( )/mdx mice), even though their utrophin levels were mildly elevated compared with age-matched controls. Thus, membrane stabilization was not sufficient to provide protection during prolonged disease. Consequently, we reinvestigated skeletal muscle regeneration in [[ADAM12]] transgenic mice ([[ADAM12]]( )) after a knife cut lesion and observed that the regeneration process was significantly impaired. [[ADAM12]] seemed to inhibit the satellite cell response and delay myoblast differentiation. These results discourage long-term therapeutic use of [[ADAM12]]. They also point to impaired regeneration as a possible factor in development of muscular dystrophy.
