Multiexon skipping using the three-PPMO-based cocktail in immortalized myoblast lines. (a) RT-PCR of immortalized CXMDJ clone 9 treated with PMO or PPMO. Exon 6 to 9 skipping efficiency for each PMO and PPMO compound is depicted as a bar graph and EC50 values are noted on the right-hand site. Exon skipping efficiency is represented as the mean ± standard deviation. N = 3; ***P < 0.001. NT, not treated. (b) Western blotting analysis for dystrophin expression. M, high-molecular-weight protein marker. EC50, effective concentration; PPMO, Pip8b2-conjugated PMO.
