New insight into the physiology of cardiac muscle may lead to the development of therapeutic strategies that exploit an inherent protective state of the heart. The research discovers a state of ...

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 ...

The sarcomere is the most basic contractile unit in skeletal and cardiac muscle. Mutations in genes encoding sarcomeric proteins give rise to heritable myopathies, although muscle function is more ...

Cardiac muscle tissue is only found in your heart. It performs involuntary, coordinated contractions that allow your heart to pump blood through your circulatory system. Cardiac muscle tissue is one ...

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 ...

Researchers have identified a novel mechanosensitive regulation of epithelial tube contraction. Many of the fundamental processes of life rely on biological structures known as epithelial tubes. These ...

The paper by Parmley et al. in this issue calls attention to the possible therapeutic use of glucagon in view of its possible inotropic and chronotropic effects in man. Such effects have previously ...

Researchers from Harvard and Emory University report that they have developed the first fully-autonomous biohybrid fish from human stem-cell derived cardiac muscle cells. The artificial fish swims by ...
