Each cardiac muscle cell can have over 5,000 sarcomeres, which compounds both the shortening and relaxation events. "This process appears to be regulated by myosin-binding protein-C (cMyBP-C), which ...

This study investigates the role of a key interaction between Tropomyosin (Tpm) and Troponin T (TnT) in the regulation of cardiac muscle contraction, with a particular focus on understanding ...

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 ...

A team of researchers have discovered that a mutation in a ribosomal protein found specifically in heart and skeletal muscle leads to impaired cardiac contractility in mice. The mutation was found to ...

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 ...
