PAX7 and Cachexia: Compared to LC-cachexia mice, in muscles of LC-cachexia and unloaded rodents, a significant decline (only in the LC 30-days + 15-day I group) in the counts of myoblast (Pax-7+ and MyoD+, −49% change) was detected, whereas no significant differences in myocyte (MyoD+ and myogenin+) numbers were observed (Figure 8B,D and Figure 9A,B).
