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 ...

The type 1 ryanodine receptor (RyR1) is an important calcium release channel in skeletal muscles essential for muscle contraction. It mediates calcium release from the sarcoplasmic reticulum, a ...

Researchers have developed a novel method for simultaneously recording action potentials (APs)—temporary changes in electrical potential when cells become excited—and calcium transients—calcium ...

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 ...

New research has identified the specific biological mechanism behind the muscle dysfunction found in myotonic dystrophy type 1 (DM1) and further shows that calcium channel blockers can reverse these ...

Calcium is one of the most vital minerals for the human body, playing an essential role in maintaining strong bones, healthy teeth, and numerous bodily functions. While many people associate calcium ...

Biomedical engineers have grown muscles in a lab to better understand and test treatments for a group of extremely rare muscle disorders called dysferlinopathy or limb girdle muscular dystrophies 2B ...

Calcium-activated ion channels in smooth muscle cells translate intracellular calcium signals into changes in membrane potential and contractile tension. The most prominent of these channels are the ...

When most people hear “calcium,” they immediately think of strong bones and teeth. While this connection is certainly valid, calcium carbonate’s benefits extend far beyond skeletal support. This ...
