In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.

From the first nerve signal to the final movement, your muscles rely on a complex chain of events involving nerves, proteins, and energy. Actin and myosin filaments slide past each other to create ...

Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction. Actin is one of the most abundant proteins in eukaryotes. It ...

University of Florida scientists have used gene therapy to eliminate disabling muscle contractions in a mouse model of the most common form of adult-onset muscular dystrophy. University of Florida ...

Time under contraction is not directly measured in a typical weight training program. Most people really don't even think about the number of seconds a given muscle is forced to work. Indirectly, ...

Cancer patients often lose excessive amounts of weight. This affects up to 80% of patients and is mainly due to a decrease in muscle mass and fatty tissue. This cancer-induced cachexia (CIC) is ...
