More than 30 rare muscular dystrophy types cause progressive muscle weakness from inherited gene mutations. Combined, they affect about 1 in 5,000 to 8,000 people. Common subtypes vary by age of onset ...

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 ...

Isolating individual muscle fibers and characterizing their myosin heavy chain (MHC) content using SDS-PAGE has become an increasingly common method for describing skeletal muscle fiber type ...

Biological muscles act as flexible actuators, generating force naturally and with an impressive range of motion. Unsurprisingly, scientists and engineers have been striving to build artificial muscles ...

Tsukuba, Japan—Different types of exercise encourage the formation of different types of muscle fibers, or the cells that make up your muscles. Slow twitch muscle fibers support endurance activities ...
