NCAM1 and Cachexia: When we extended the analysis to control and cachectic muscles, we noticed a significant increase in the number of NCAM-expressing muscle fibers, but not of NCAM-expressing satellite cells, in cachexia (0.6 ± 0.2% and 2.2 ± 0.4% in control muscle and cachectic muscle, respectively; Figure 2Db, 2Dc and 2E).
