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 ...

The heart is the only muscle that contracts and relaxes continuously over a lifetime to pump oxygen-rich blood to the body's organs. Researchers at UT Southwestern Medical Center now have identified a ...

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 ...

Science reveals that your lower legs act as a secondary circulatory pump, pushing blood against gravity to protect your heart ...

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 ...

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 ...

Researchers at TalTech have concluded that a lack of creatine does not cause heart failure, contrary to previous assumptions. However, their surprising discoveries about heart muscle cells could lead ...

Researchers from the Heart Center of the University Medical Center Göttingen (UMG) led by Priv.-Doz. Dr. Sören Brandenburg have identified a protein that plays a central role in the heart's adaptation ...
