MiR-208b Regulates the Conversion of Skeletal Muscle Fiber Types by Inhibiting Mettl8 Expression
Frontiers in Genetics, 2022 Skeletal muscle, the main source of animal meat products, contains muscle fiber as a key unit. It is well known that transformation takes place between different types of muscle fibers, however, the conversion mechanism is not clear. In a previous study,

Aging of Skeletal Muscle Fibers [PDF]
Annals of Rehabilitation Medicine, 2015 Aging has become an important topic for scientific research because life expectancy and the number of men and women in older age groups have increased dramatically in the last century. This is true in most countries of the world including the Republic of Korea and the United States. From a rehabilitation perspective, the most important associated issue

Cell Death Discovery, 2021 Skeletal muscle denervation occurs in diverse conditions and causes severe muscle atrophy. Signaling by mammalian target of rapamycin complex 1 (mTORC1) plays a central role in the maintenance of skeletal muscle mass by regulating net protein balance ...

Targeted myostatin loss-of-function mutation increases type II muscle fibers in Meishan pigs
Journal of Integrative Agriculture, 2022 Myostatin (MSTN) is a negative regulator of skeletal muscle growth and development. The skeletal muscle in MSTN−/– mice is significantly hypertrophied, with muscle fiber type II increasing significantly while muscle fiber type I decreasing.

Human and Rodent Skeletal Muscles Express Angiotensin II Type 1 Receptors
Cells, 2020 Abundant evidence reveals that activation of the renin-angiotensin system promotes skeletal muscle atrophy in several conditions including congestive heart failure, chronic kidney disease, and prolonged mechanical ventilation. However, controversy exists

Mechanisms of exercise-induced preconditioning in skeletal muscles
Redox Biology, 2020 Endurance exercise training promotes numerous biochemical adaptations within skeletal muscle fibers culminating into a phenotype that is safeguarded against numerous perils including doxorubicin-induced myopathy and inactivity-induced muscle atrophy ...

Foods, 2022 Skeletal muscle fiber types can contribute in part to affecting pork quality parameters. Biceps femoris (Bf) (fast muscle or white muscle) and Soleus (Sol) (slow muscle or red muscle) are two typical skeletal muscles characterized by obvious muscle fiber

Mitochondrial Properties in Skeletal Muscle Fiber
Cells, 2023 Mitochondria are the primary source of energy production and are implicated in a wide range of biological processes in most eukaryotic cells. Skeletal muscle heavily relies on mitochondria for energy supplements. In addition to being a powerhouse, mitochondria evoke many functions in skeletal muscle, including regulating calcium and reactive oxygen ...

Mechanical Properties of Single Muscle Fibers: Understanding Poor Muscle Quality in Older Adults with Diabetes [PDF]
Annals of Geriatric Medicine and Research, 2020 Background While aging causes muscle weakness, type 2 diabetes mellitus (T2DM) is also considered a high-risk factor for the induction of skeletal muscle weakness.
