According to the research, the protein seems to sense stress on the muscle cells and adjusts sarcomere shortening—and consequently, muscle contraction—based on how hard the heart needs to work. If ...

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 ...

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 ...

To build the model, scientists used cardiac muscle and connective tissue cells from rats. Scientists in Canada have developed a three-dimensional "heart-on-a-chip" that could mark a major step forward ...

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 ...
