In-Depth Information
In dystroglycan KD zebrafish, we observed several defects that resemble human
congenital myopathies found in both DMD patients and mdx mice including (1) rapid,
progressive muscular degeneration, (2) immobility, (3) muscle defects, and (4) bent
spine (notochord). Although the zebrafish is phylogenically distant from humans, key
gene families have been shown to be highly conserved, and dystroglycan knockdown
performed by simple injection into wild-type animals is straightforward and highly
reproducible. An additional compelling advantage of this model organism is that a
battery of disease-specific zebrafish assays can be designed to assess drug effects.
