Mitochondrial dysfunction and its association with age-related disorders

The article "Mitochondrial Dysfunction and Its Association with Age-Related Disorders" by Indumathi Somasundaram et al. explores the role of mitochondrial dysfunction in aging and age-related diseases. Mitochondria, crucial for cellular energy production and homeostasis, are susceptible to various stressors that lead to their dysfunction, including oxidative stress, calcium overload, and mutations in mitochondrial DNA (mtDNA). These factors contribute to increased reactive oxygen species (ROS) production, impaired apoptosis, and altered calcium signaling, ultimately leading to cellular damage and aging. The article highlights the importance of mitophagy, the process of selective autophagy of dysfunctional mitochondria, in maintaining mitochondrial integrity and preventing age-related degenerative diseases. It also discusses the potential therapeutic strategies targeting mitochondrial dysfunction, such as caloric restriction, exercise, and pharmacological interventions, to improve health and longevity. The authors emphasize the need for further research to understand the detailed molecular mechanisms underlying mitochondrial dysfunction and to develop effective anti-aging therapies.The article "Mitochondrial Dysfunction and Its Association with Age-Related Disorders" by Indumathi Somasundaram et al. explores the role of mitochondrial dysfunction in aging and age-related diseases.
