Abstract

It has been suggested that muscle wasting in muscular dystrophy is causally related to a perturbation of Ca2+ -homeostasis in the muscle fiber (8,525–530) due to an increased permeability of the sarcolemmal membrane. An elevated sarcoplasmic Ca2+ concentration would result from an increased Ca2+ -influx and would thus lead to an activation of Ca2+ -dependent proteases. Ca2+ has also been shown to play an important role in the regulation of glucose-1,6-biphosphate (531,532) a powerful effector of several enzymes in glucose metabolism (533). This modulator has been shown to be significantly reduced in muscles of dystrophic mice (534,535).
