The preferential involvement of glycolytic fibers in DMD may be directly related to different cellular and biochemical characteristics, such as the presence/quantity of satellite cells (SCs) and peroxisome proliferator-activated receptor-gamma coactivator (PGC)-1α protein (PGC-1α), as both are found in greater amounts in oxidative muscles when compared with glycolytic muscles [7,8]. Here, PPARGC1A is linked to Duchenne muscular dystrophy.
