Calcium ions orchestrate contraction and relaxation in airway smooth muscle by regulating excitation–contraction coupling. In quiescent cells, basal cytosolic Ca2+ is maintained at nanomolar levels by ...

A new role of calcium in the development of muscles has been reported by two RIKEN biologists. Stress is generally damaging and destructive, but it can sometimes spur productivity and creation. This ...

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 critical for bone health, optimal muscle activity, and other body processes such as blood clotting and heart function. How much calcium you need depends on your age and stage of life. Share ...
