Special Issue Information

Dear Colleagues,

Autophagy and apoptosis are two key processes for maintaining cellular homeostasis in tissues and are regulated through various and highly coordinated signal transduction mechanisms.

Also in skeletal muscle, a plastic tissue that reacts and adjusts to several physiological and pathological conditions, autophagy and apoptosis are finely tuned and may have both beneficial and harmful effects, depending on the condition of the tissue and their level of activation. For instance, both processes may impinge the fate of skeletal muscle after damage and contribute to the pathogenesis of diseases such as myopathies and muscular dystrophies.

In this Special Issue, we will collect studies focused on the role of autophagy and/or apoptosis in skeletal muscle homeostasis, injury, and repair and in skeletal muscle diseases such as myopathies, muscular dystrophies, atrophy, and sarcopenia, also focusing on the interaction with immune system cells. Furthermore, we encourage research on mitophagy and mitochondrial apoptotic signaling in skeletal muscle pathophysiology, due to mitochondria’s critical role in determining cell life and death. Finally, we aim to gather studies exploring the possibility of targeting autophagy/apoptosis as novel therapeutic strategies for the treatment of muscle diseases. Original research papers, review articles, communications, perspectives, and commentaries are welcome.

Duchenne muscular dystrophy (DMD) is a genetic progressive muscle-wasting disorder that leads to rapid loss of mobility and premature death. The absence of functional dystrophin in DMD patients reduces sarcolemma stiffness and increases contraction damage, triggering a cascade of events leading to muscle cell degeneration, chronic inflammation, and deposition of fibrotic and adipose tissue. Efforts in the last decade have led to the clinical approval of novel drugs for DMD that aim to restore dystrophin function. However, combination therapies able to restore dystrophin expression and target the myriad of cellular events found impaired in dystrophic muscle are desirable. Muscles are higher energy consumers susceptible to mitochondrial defects. Mitochondria generate a significant source of reactive oxygen species (ROS), and they are, in turn, sensitive to proper redox balance. In both DMD patients and animal models there is compelling evidence that mitochondrial impairments have a key role in the failure of energy homeostasis. Here, we highlighted the main aspects of mitochondrial dysfunction and oxidative stress in DMD and discussed the recent findings linked to mitochondria/ROS-targeted molecules as a therapeutic approach. In this respect, dual targeting of both mitochondria and redox homeostasis emerges as a potential clinical option in DMD. Full article

Mitochondria are cellular organelles that play an essential role in generating the chemical energy needed for the biochemical reactions in cells. Mitochondrial biogenesis, i.e., de novo mitochondria formation, results in enhanced cellular respiration, metabolic processes, and ATP generation, while autophagic clearance of mitochondria (mitophagy) is required to remove damaged or useless mitochondria. The balance between the opposing processes of mitochondrial biogenesis and mitophagy is highly regulated and crucial for the maintenance of the number and function of mitochondria as well as for the cellular homeostasis and adaptations to metabolic demands and extracellular stimuli. In skeletal muscle, mitochondria are essential for maintaining energy homeostasis, and the mitochondrial network exhibits complex behaviors and undergoes dynamic remodeling in response to various conditions and pathologies characterized by changes in muscle cell structure and metabolism, such as exercise, muscle damage, and myopathies. In particular, the involvement of mitochondrial remodeling in mediating skeletal muscle regeneration following damage has received increased attention, as modifications in mitophagy-related signals arise from exercise, while variations in mitochondrial restructuring pathways can lead to partial regeneration and impaired muscle function. Muscle regeneration (through myogenesis) following exercise-induced damage is characterized by a highly regulated, rapid turnover of poor-functioning mitochondria, permitting the synthesis of better-functioning mitochondria to occur. Nevertheless, essential aspects of mitochondrial remodeling during muscle regeneration remain poorly understood and warrant further characterization. In this review, we focus on the critical role of mitophagy for proper muscle cell regeneration following damage, highlighting the molecular mechanisms of the mitophagy-associated mitochondrial dynamics and network reformation.
