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 ...

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

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 ...

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 ...

New study outlines scalable protocol to enhance development and understanding of human pluripotent stem cells in cardiac muscles. A Mount Sinai-led team has developed a reproducible and scalable ...
