When a muscle contracts, the parts of a sarcomere "shorten" and come closer together. Each cardiac muscle cell can have over 5,000 sarcomeres, which compounds both the shortening and relaxation events ...

Researchers find that deficiency in RPL3L, a ribosome expressed in heart and skeletal muscle, impairs cardiac contractility due to delayed mRNA translation Fukuoka, Japan—A team of researchers have ...

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 ...

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 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 ...

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