Over-expression of mOR23 in mdx muscles protects against membrane injury after eccentric muscle contractions. a Representative images of gastrocnemius muscles from mdx and Tg-mdx mice which underwent eccentric contraction (EC) or not (CTL, contralateral muscle). Evans blue dye (EBD) fluorescence identified myofibers with increased membrane permeability. Bar = 100 μm. b mdx muscles were significantly more permeable to EBD after EC than Tg-mdx muscles. Each line represents the CTL and EC muscle of one mouse, n = 7 for each genotype with *p < 0.05
