Expression of dystrophin restores the dystrophin-associated protein complex (DAPC) to the sarcolemma in the PPMO-treated dKO mice. DAPC components α- and β-sarcoglycan, β-dystroglycan, and nNOS were detected by immunostaining in tissue cross-section of tibialis anterior (TA) muscles from PPMO-treated dKO mice (right panel), compared with C57BL6 normal mice (left panel) and untreated dKO mice (middle panel). Bar = 100 µm. dKO, double-knockout; nNOS, neuronal nitric oxide synthase; PPMO, peptide-conjugated phosphorodiamidate morpholino oligomer.
