MAPK3 and Duchenne muscular dystrophy: GO Biological Process term analysis for DEGs in DMD skeletal muscle compared to healthy muscle (Figure 7) identified the following terms: extracellular matrix organization (p = 6.25 × 10−17), axonogenesis (p = 9.35 × 10−5), regulation of cell migration (p = 3.39 × 10−12), synapse organization (p = 0.009), nervous system development (p = 1.87 × 10−4), skeletal system development (p = 2.22 × 10−4), regulation of ERK1 and ERK2 cascade (p = 5.15 × 10−8), and calcium ion transmembrane import into cytosol (p = 0.001).
