Mutations in a calcium ion channel anoctamin 5 (ANO5), commonly found in muscle cells, cause the debilitating disease called limb girdle muscular dystrophy 2L (LGMD2L). Characterized by progressive ...

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 ...

New cause found: Advanced imaging showed statins binding to RyR1 muscle receptors, disrupting calcium flow and possibly causing cramps, stiffness, or weakness. Why it matters: Muscle symptoms lead ...

New mechanism found: Researchers discovered that statins can bind to and activate ryanodine receptors in muscle cells, potentially explaining muscle pain in some patients. Why it matters: Uncovering ...

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 ...

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 ...

At a time when there are seemingly endless supplements being sold to consumers, we asked a nutritionist to name the top for ...

Dairy tends to be high in calcium, but milk and yogurt aren’t the only high-calcium foods. Other options include canned fish, ...

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 ...

Calcium (1,000-1,200 mg per day): Dairy products, including milk, yogurt, and cheese, leafy greens like kale and broccoli, ...
