The contraction of smooth muscle is an essential process underpinning diverse physiological functions ranging from gastrointestinal motility to vascular regulation. At its core, smooth muscle ...

The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

Researchers at UT Southwestern Medical Center at Dallas are the first to use genetically engineered mice containing a fluorescent molecule to examine in real time the chemical reactions that result in ...

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

Researchers engineered mice with a mutation (E3896A) in the RyR1 calcium-binding site, eliminating calcium-induced calcium release (CICR) without affecting depolarization-induced calcium release. The ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study. The flow of water within a muscle fiber may dictate how quickly muscle can contract, ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

Muscle is known to regenerate through a complex process that involves several steps and relies on stem cells. Now, a new study led by researchers at Pompeu Fabra University (UPF, Spain)/Centro ...

A research team affiliated with UNIST has unveiled a new type of artificial muscle that can seamlessly transition from soft ...

Researchers describe a new mechanism for muscle repair after physiological damage relying on the rearrangement of muscle fibre nuclei, and independently of muscle stem cells. Muscle is known to ...
