Bcl-2 and Bax immunohistochemistry was examined in the skeletal muscle of rats after cutting the sciatic nerve, as a model of denervation and reinnervation, and in the anterior tibialis muscle of rats after an intramuscular injection of metoclopramide, as a model of necrosis and regeneration of muscle fibers, to better understand the role of these proteins in muscle disorders. An increase in Bax immunoreactivity was seen in long-standing denervated and reinnervated muscle fibers. Bcl-2 and Bax immunoreactivity was limited to macrophages in necrotic muscle fibers at 24 h after the intramuscular injection of metoclopramide. However, increased Bax immunoreactivity was observed in regenerating muscle fibers by the fourth day after the injection. Muscle fiber nuclei with the morphological features of apoptosis were not observed in rat muscles after the intramuscular injection of metoclopramide or after the severing of the sciatic nerve. Furthermore, using the Tunel method, no stained nuclei were observed in the two groups of animals. Our observations in the experimental models of skeletal muscle denervation-reinnervation and necrosis-regeneration here described suggest that modification in the intensity of the Bax protein is not related to the process of cell death but rather that increased Bax expression is associated with muscle fiber regeneration.
