Statins are amongst the most widely prescribed drugs for those at risk of cardiovascular disease, lowering cholesterol levels by inhibiting 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase. Although effective in prevention of cardiovascular disease, statin use is associated with muscle weakness, myopathies and, in rare cases, fatal rhabdomyolysis. As simvastatin, a commonly prescribed statin, can promote Ca2+ release from sarcoplasmic reticulum (SR) vesicles, we investigated if simvastatin could directly activate skeletal (RyR1) and cardiac (RyR2) ryanodine receptors.

High 17β-Estradiol (E2) concentrations in isolated ventricular myocytes as well as a lack of ovarian hormones in cardiac muscle of ovariectomized (OVX) rodents has been shown to lead to arrhythmogeni...
Excitation-contraction (EC) coupling in skeletal muscles operates through a physical interaction between the dihydropyridine receptor (DHPR), acting as a voltage sensor, and the ryanodine receptor (Ry...
Core myopathies are a group of childhood muscle disorders caused by mutations of the ryanodine receptor (RyR1), the Ca2+ release channel of the sarcoplasmic reticulum. These mutations have previously ...

A pharmaceutical preparation of ezetimibe and simvastatin that is used in the treatment of HYPERCHOLESTEROLEMIA and HYPERLIPIDEMIAS.
Large, multinucleate single cells, either cylindrical or prismatic in shape, that form the basic unit of SKELETAL MUSCLE. They consist of MYOFIBRILS enclosed within and attached to the SARCOLEMMA. They are derived from the fusion of skeletal myoblasts (MYOBLASTS, SKELETAL) into a syncytium, followed by differentiation.
