This genetic model suggests otherwise, indicating that coupled gating or other mechanical interactions, rather than CICR, drive activation of uncoupled RyR1 channels. Interestingly, the researchers ...

Researchers have identified the role of the large Maf transcription factor family in regulating fast twitch muscle fibers. A mouse model lacking Maf expression in the skeletal muscles exhibited a ...

Researchers building a model of muscle damage in a cultured system found that components leaking from broken muscle fibers activate ''satellite cells,'' which are muscle stem cells. While attempting ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have shown that the protein Musashi-2 (Msi2) plays a key role in the regulation of mass and metabolic processes in skeletal muscle. They ...

Hidden inside every organ, microscopic fibers form a scaffolding that quietly shapes how we move, think, and heal. For the ...

The muscular system works to control the movement of our body and internal organs. Muscle tissue contains something called muscle fibers. Muscle fibers consist of a single muscle cell. They help to ...

slow-twitch muscle fibers, which move more slowly but help to keep you moving longer fast-twitch muscle fibers, which help you move faster, but for shorter periods “Twitch” refers to the contraction, ...
