Altered Relaxation and Mitochondria-Endoplasmic Reticulum Contacts Precede Major (Mal)Adaptations in Aging Skeletal Muscle and Are Prevented by Exercise.

Sarcopenia, or age-related muscle dysfunction, contributes to morbidity and mortality. Besides decreases in muscle force, sarcopenia is associated with atrophy and fast-to-slow fiber type switching, which is typically secondary to denervation in humans and rodents. However, very little is known...

Impact of physical activity on physical function, mitochondrial energetics, ROS production, and Ca handling across the adult lifespan in men.

Aging-related muscle atrophy and weakness contribute to loss of mobility, falls, and disability. Mitochondrial dysfunction is widely considered a key contributing mechanism to muscle aging. However, mounting evidence positions physical activity as a confounding factor, making unclear whether muscle mitochondria...

Role of cardiolipin in skeletal muscle function and its therapeutic implications.

Cardiolipin, a unique phospholipid predominantly present in the inner mitochondrial membrane, is critical for maintaining mitochondrial integrity and function. Its dimeric structure and role in supporting mitochondrial dynamics, energy production, and mitophagy make it indispensable for skeletal muscle health. This...

Mitochondrial calcium uptake declines during aging and is directly activated by oleuropein to boost energy metabolism and skeletal muscle performance.

Mitochondrial calcium (mtCa) uptake via the mitochondrial calcium uniporter (MCU) couples calcium homeostasis and energy metabolism. mtCa uptake via MCU is rate-limiting for mitochondrial activation during muscle contraction, but its pathophysiological role and therapeutic application remain largely uncharacterized. By profiling...
