Figure 4

Immunohistochemistry of mdx TA muscles treated with S56 PMO showed higher sarcolemmal expression of utrophin. (a) TA muscles were stained with α-bungarotoxin (green), utrophin antibody (red) and wheat germ agglutinin (cyan). The control PMO and S56 PMO treated cryosections were also stained with utrophin pre-immune sera as control. Scale bar = 100 µm. The figures showed synaptic expression of utrophin in control PMO, and both synaptic and extra-synaptic sarcolemma associated expression of utrophin in S56 PMO treated mice. (b) Quantification of utrophin expression in sarcolemma normalized with WGA expression. S56 PMO treated muscles showed significantly higher expression of utrophin (****p = 0.0001, n = 4 mice for both groups). Statistical analysis performed by Mann–Whitney nonparametric test.
