Special Issue Information

Dear Colleagues,

Mitochondria are organelles that are now well-acknowledged to govern multiple cellular processes beyond their classical role in energy metabolism. Comprehensive and complicated pathways regulate constant mitochondrial biogenesis, fusion, fission, mitophagy, and other activities to maintain mitochondrial homeostasis, fulfilling the specific demands of different cell types. Though mitochondrial dysfunction and oxidative stress presents as a common cellular abnormality, studies have revealed distinct mitochondrial pathologies underlying different diseases.    

In the last decade, studies of mitochondria-targeted interventions against disease pathology have risen rapidly, among which mitochondrial pharmaceuticals represents a major topic. Many agents have been developed which target mitochondrial oxidative phosphorylation, membrane potential, metabolite transport, biogenesis, dynamic, redox state etc. to restore mitochondrial homeostasis in affected tissues. To help advance related research in the field, this Special Issue aims to collect relevant studies focusing on (i) natural compounds and derivatives, (ii) designed compounds, and (iii) mitochondria-targeted delivery systems, to improve pathologies associated with metabolism and aging. 

The journal Pharmaceuticals invites experts in the field to contribute to Special issue with both reviews and original research articles related to mitochondria-targeted interventions against diseases associated with metabolism and aging.

Mitochondria are structurally and functionally unique organelles in male gametes. Apparently, as the only organelles remaining in mature sperm, mitochondria not only produce adeno-sine triphosphate (ATP) through oxidative phosphorylation (OXPHOS) to support sperm mobility, but also play key roles in regulating reactive oxidation species (ROS) signaling, calcium homeostasis, steroid hormone biosynthesis, and apoptosis. Mitochondrial dysfunction is often associated with the aging process. Age-dependent alterations of the epididymis can cause alterations in sperm mitochondrial functioning. The resultant cellular defects in sperm have been implicated in male infertility. Among these, oxidative stress (OS) due to the overproduction of ROS in mitochondria may represent one of the major causes of these disorders. Excessive ROS can trigger DNA damage, disturb calcium homeostasis, impair OXPHOS, disrupt the integrity of the sperm lipid membrane, and induce apoptosis. Given these facts, scavenging ROS by antioxidants hold great potential in terms of finding promising therapeutic strategies to treat male infertility. Here, we summarize the progress made in understanding mitochondrial dysfunction, aging, and male infertility. The clinical potential of antioxidant interventions was also discussed. Full article
