In TA muscle, Dp427 was detected in wild‐type mice and not the DMD mouse models; Dp140 was not detected in any TA muscle studied; and Dp71 was detected in mdx, but not wild‐type, mdx52 or DMD‐null mice by dystrophin western blot using DysA antibody (Figure3D). This evidence concerns the gene DMD and Duchenne muscular dystrophy.
