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 ...

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 ...

Canadian researchers have developed a beating three-dimensional heart-on-a-chip with real-time cellular sensing, offering a safer and more precise way to test drugs and study heart disease.

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 ...

Advancements in the study of two rare heart conditions—peripartum cardiomyopathy (PPCM), and dilated cardiomyopathy (DCM)—contributed by researchers at the Perelman School of Medicine at the ...

One promising strategy to remuscularize the injured heart is the direct cardiac reprogramming of heart fibroblast cells into cardiomyocytes. Researchers have identified TBX20 as the key missing ...

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 ...
