Skeletal muscle has multiple functions and is a key component of the locomotor system. It consists of carbohydrates and amino acids for different tissues such as skin, heart and brain. It contributes to the maintenance of blood glucose levels during periods of starvation. Skeletal muscle health is particularly important for the prevention of various diseases. This review discusses various aspec...

The sarcomere is the fundamental unit of cardiac and skeletal muscle contraction. During the last ten years, there has been growing awareness of the etiology of skeletal and cardiac muscle diseases originating in the sarcomere, an important evolving field. Many sarcomeric diseases affect newborn children, i. e. are congenital myopathies. The discovery and characterization of several myopathies ...

Currently, no pharmacological therapies treat skeletal muscle insulin resistance in pathological conditions such as type 2 diabetes, age-associated diseases, and cancer. Therefore, there is an unmet need to identify the molecular mechanisms ...The events governing glucose uptake have potential for managing obesity, With current treatments target ...

Osteoclasts are bone-resorbing cells essential for skeletal remodeling and regeneration. However, excessive osteoclasts often contribute to prevalent bone degenerative diseases such as osteoporosis, arthritis, and cancer bone metastasis. Osteoclast dysregulation is also associated with rare disorders such as osteopetrosis, pycnodysostosis, Paget's disease, and Gorham-Stout syndrome. The nuclear...

The skeletal muscle Ca(2+) release channel, also known as ryanodine receptor type 1 (RyR1), is the largest ion channel protein known and is crucial for effective skeletal muscle contractile activation. RyR1 function is controlled by Cav1.1, a voltage gated Ca(2+) channel that works mainly as a voltage sensor for RyR1 activity during skeletal muscle contraction and is also fine-tuned by Ca(2+), ...

Metabolic abnormalities develop in various chronic diseases and lead to progressive catabolism with decrements in the skeletal musculature that result in muscle atrophy. We investigated pathways of skeletal muscle proteolysis using an experimental model of chronic left-ventricular dysfunction. Skeletal muscle atrophy developed in wild-type mice 12 weeks following myocardial infarction accompani...
