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 ...

Activated by quarter-second-long light pulses, the molecular machines allowed scientists to control calcium signaling in a cardiac myocyte cell culture, causing the inactive cells to fire. "The ...

Researchers at Rice University used light-activated molecular machines to trigger intercellular calcium wave signals which they say demonstrates a new strategy for controlling cellular activity. The ...

Calcium deficiency occurs when the body does not have enough calcium to support vital functions such as nerve signalling, muscle contraction, and bone strength. While traditionally associated with ...

(Nanowerk News) One of the main ways cells “talk” to each other to coordinate essential biological activities such as muscle contraction, hormone release, neuronal firing, digestion and immune ...
