Muscle regeneration in GM of WT and Nrf2^tKO animals after CTX-induced injury. (a) Myh3 level in GM; qRT-PCR; n = 4-6. (b) Representative photos of immunofluorescent staining for eMyHC and (c) quantification of the percentage of eMyHC positive myofibers; n = 5. (d) Cross sectional area of fibers 7 days after CTX; n = 3-4. (e) Mean fiber area 7 days after CTX; n = 3-4. The data are presented as mean +/− SEM; ***p ≤ 0.001 vs. day 0, one-way ANOVA with Tukey’s post hoc test. The scale bars represent 100 μm
