- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

The giant cytoskeletal protein obscurin, represented in Caenorhabditis elegans by its orthologue UNC-89, plays a pivotal role in organising the intricate architecture of striated muscles. UNC-89 is ...

When a muscle contracts, the parts of a sarcomere "shorten" and come closer together. Each cardiac muscle cell can have over 5,000 sarcomeres, which compounds both the shortening and relaxation events ...

Companion studies suggest muscle begins to decline decades before sarcopenia takes hold for keeps. The best part: The process ...

Setting out to identify all proteins that make up the sarcomere, the basic contractile unit of muscle cells, resulted in an unexpected revelation, providing experimental evidence that helps explain a ...

Atrial fibrillation, heart failure and stroke – hypertrophic cardiomyopathy can lead to many serious health conditions and is a major cause of sudden cardiac death in people younger than 35. „The ...

No one can live without a heart pumping blood to the rest of the body. New research from the University of Missouri School of Medicine reveals more information about this vital function and how it’s ...
