Multiple actions of the anthracycline daunorubicin on cardiac ryanodine receptors.
Our aim was to examine the molecular basis for acute effects of the anthracycline daunorubicin on cardiac ryanodine receptor (RyR2) channels and cardiac calsequestrin (CSQ2). Cardiotoxic effects of anthracyclines preclude their chemotherapeutic use in patients with pre-existing heart conditions. To address this significant problem, the mechanisms of anthracycline toxicity must be defined but at...

متن کاملRyanodine receptors in smooth muscle.
The sarcoplasmic reticulum (SR) of smooth muscle is endowed with two different types of Ca2+ release channels, i.e. inositol 1,4,5-trisphosphate receptors (IP3Rs) and ryanodine receptors (RyRs). In general, both release channels mobilize Ca2+ from the same internal store in smooth muscle. While the importance of IP3Rs in agonist-induced contraction is well established, the role of RyRs in excit...
متن کاملRyanodine Receptors: Structure
Ryanodine receptors (RyRs) are huge ion channels that are responsible for the release of Ca2 from the sarco/endoplasmic reticulum. RyRs form homotetramers with a mushroom-like shape, consisting of a large cytoplasmic head and transmembrane stalk. Ca2 is a major physiological ligand that triggers opening of RyRs, but a plethora of modulatory proteins and small molecules in the cytoplasm and sarc...
متن کاملRegulation of mammalian ryanodine receptors.
Ryanodine receptors (RyRs) are large, high conductance Ca2+ channels that control the level of intracellular Ca2+ by releasing Ca2+ from an intracellular compartment, the sarco/endoplasmic reticulum. Mammalian tissues express 3 closely related ryanodine receptors (RyRs) known as skeletal muscle (RyR1), cardiac muscle (RyR2) and brain (RyR3). The RyRs are isolated as 30S protein complexes compri...
