Figure 5. Arg-ii^-/- mice reveal decreased inflammatory markers in aging skeletal muscles. mRNA expression levels of inflammatory markers and cytokines analyzed by qRT-PCR in soleus and tibialis from male (A) and female (B) young and old wild type (wt) and arg-ii^-/- (ko) mice. One-way ANOVA was applied. n = 4–7 mice per group. ^*p < 0.05, ^**p < 0.01, ^***p < 0.001 between the groups.
