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 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 ...

Scientists at the University of Cincinnati and colleagues report that a regulatory protein found in skeletal muscle fiber may play an important role in the body’s fight or flight response when ...

“This article illuminates the biology behind EDG-5506, demonstrating that modulation of fast skeletal muscle contraction protects against muscle injury, degeneration and fibrosis in models of DMD,” ...

The connections between the nervous system and muscles develop differently across the kingdom of life. It takes newborn humans roughly a year to develop the proper muscular systems that support the ...

Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

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.

Researchers say a regulatory protein found in skeletal muscle fiber may play an important role in the body's fight or flight response when encountering stressful situations. Researchers at the ...

Muscles are made up of proteins. Myosin, a fibrous protein, serves as a molecular motor and converts the chemical energy stored inside our body into mechanical energy. The synergistic association ...

Study uncovers a polyphenol's mechanism in enhancing mitochondrial calcium uptake and muscle bioenergetics during aging. Study: Mitochondrial calcium uptake declines during aging and is directly ...
