Prospective Intervention Strategies Between Skeletal Muscle Health and Mitochondrial Changes During Aging.

Abstract

Sarcopenia is a geriatric condition characterized by a decrease in skeletal muscle mass and function, significantly impacting both quality of life and overall health. Mitochondria are the main sites of energy production within the cell, and also produce reactive oxygen species (ROS), which maintain mitochondrial homeostasis-mitophagy (clearing damaged mitochondria); mitochondrial dynamics, which involve fusion and fission to regulate mitochondrial morphology; mitochondrial biogenesis, which ensures the functionality and homeostasis of mitochondria. Sarcopenia is linked to mitochondrial dysfunction, suggesting that muscle mitochondrial function therapy should be investigated. Extrinsic therapies are extensively examined to identify new treatments for muscular illnesses including sarcopenia. Changes in muscle physiology and lifestyle interventions, such as pharmacological treatments and exercise, can modulate mitochondrial activity in older adults. This PubMed review encompasses the most significant mitophagy and sarcopenia research from the past five years. Animal models, cellular models, and human samples are well covered. The review will inform the development of novel mitochondria-targeted therapies aimed at combating age-related muscle atrophy.
