Figure 5.

Expression of Dp116 does not prevent the fiber-type abnormality in mdx:utrn^−/− muscles. Shown are entire cross-sections of quadriceps muscles stained with NADH. Dark staining indicates oxidative fibers while light staining indicates glycolytic fibers. Wild-type C57Bl/6 quadriceps show a mosaic pattern of oxidative and glycolytic fibers while both the mdx:utrn^−/− and transgenic quadriceps show a much higher proportion of oxidative fibers as well as an increase in intermediately stained fibers. Scale bar: 1 mm.
