Researchers at UT Southwestern Medical Center have identified a previously unrecognized small protein in cells of the human heart that plays a key role in heart muscle contraction. The protein is made ...

Researchers have investigated the effect of increased cell temperature on the contractility of skeletal muscle and cardiac muscle by heating the muscle proteins using advanced microscopical techniques ...

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 ...

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 ...

MHH researchers have deciphered the signalling pathway that controls the movement of mitochondria within cells during heart development. The original paper “RHOT Proteins Link Mitochondrial Motility ...

Working with heart muscle cells from diabetic rats, scientists at Johns Hopkins have located what they say is the epicenter of mischief wreaked by too much blood sugar and used a sugar-gobbling enzyme ...

As cardiovascular function ages, the heart becomes fibrotic, leading to reduced contraction, and vascular function declines, ...

ROCKVILLE, MD – In a surprising discovery, scientists have found that the heart possesses "sweet taste" receptors, similar to those on our tongues, and that stimulating these receptors with sweet ...

The cardiac troponin test detects damage to the heart muscle. Troponin is a protein that appears in the blood only when the heart muscle is damaged, as in a heart attack. There are other causes of ...
