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 ...

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

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 ...

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 ...

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 ...

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 ...
