Mitochondrial biogenesis during skeletal muscle regeneration.
Myogenesis requires energy production for the execution of a number of regulatory and biosynthesis events. We hypothesized that mitochondrial biogenesis would be stimulated during skeletal muscle regeneration. Tibialis anterior muscles of male Sprague-Dawley rats were injected with 0.75% bupivacaine and removed at 3, 5, 7, 10, 14, 21, or 35 days after injection (n = 5-7/group). Two main periods...
متن کاملAge-Associated Changes in Skeletal Muscle Regeneration: Effect of Exercise
Aim of the present short review is to provide a comprehensive update on age-associated skeletal muscle damage, regeneration, and effect of endurance and resistance type of exercise training on muscle regeneration. Decrease in muscle quantity and quality leads to disability in the aging population. The degradation rate of muscle proteins during aging increased about two times, and muscle strengt...
متن کاملRegulation of exercise-induced fiber type transformation, mitochondrial biogenesis, and angiogenesis in skeletal muscle.
Skeletal muscle exhibits superb plasticity in response to changes in functional demands. Chronic increases of skeletal muscle contractile activity, such as endurance exercise, lead to a variety of physiological and biochemical adaptations in skeletal muscle, including mitochondrial biogenesis, angiogenesis, and fiber type transformation. These adaptive changes are the basis for the improvement ...
متن کاملCharacteristics of skeletal muscle mitochondrial biogenesis induced by moderate-intensity exercise and weight loss in obesity.
There are fewer mitochondria and a reduced oxidative capacity in skeletal muscle in obesity. Moderate-intensity physical activity combined with weight loss increase oxidative enzyme activity in obese sedentary adults; however, this adaptation occurs without a significant increase in mitochondrial DNA (mtDNA), which is unlike the classic pattern of mitochondrial biogenesis induced by vigorous ac...
متن کاملMitochondrial biogenesis in fast skeletal muscle of CK deficient mice.
Creatine kinase (CK) is a phosphotransfer kinase that catalyzes the reversible transfer of a phosphate moiety between ADP and creatine and that is highly expressed in skeletal muscle. In fast glycolytic skeletal muscle, deletion of the cytosolic M isoform of CK in mice (M-CK-/-) leads to a massive increase in the oxidative capacity and of mitochondrial volume. This study was aimed at investigat...
