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 ...

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 ...

The human heart, often described as the body's engine, is a remarkable organ that tirelessly beats to keep us alive. At the core of this vital organ, intricate processes occur when it contracts, where ...

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 substances can ...

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 ...

In a decades-long effort, researchers have discovered how to tweak the molecular pathways that turn heart muscle motors up or ...

Premature ventricular contraction (PVC) is a type of abnormal heartbeat, or arrhythmia. It happens when the heartbeat begins in the lower, rather than the upper, heart chambers. This creates an ...
