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 ...

Most cells typically have one nucleus that holds its genomic DNA. Muscle fibers, however, are large, individual cells that contain many nuclei. Reporting in Nature Communications, scientists have used ...

Most fitness-minded people have probably heard of fast- and slow-twitch muscle fibers. However, the distinction can be somewhat mysterious, especially in the context of understanding how it relates to ...

A muscle fiber consists of just one cell, but many nuclei. A team has now shown just how varied these nuclei are. The study can help us better understand muscle diseases such as Duchenne muscular ...

For example, the researchers observed that the regenerating muscle contained more active genes responsible for triggering muscle growth. "What really astonished us, however, was the fact that, in both ...

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 ...

Previous studies have shown that, in obesity, deposition of lipid droplets in skeletal muscles and changes of muscle fiber types can both contribute to insulin resistance. However, the relationship ...

Muscles are remarkably effective systems for generating controlled force, and engineers developing hardware for robots or ...
