چکیده

Cardiac contraction is initiated by Ca(2+) leaving the sarcoplasmic reticulum through the ryanodine receptor (RyR). Although opening of the RyR can be modified by various ligands, these have no maintained effect on contraction. We conclude that modulation of the RyR controls sarcoplasmic reticulum Ca(2+) content rather than cytoplasmic Ca(2+) concentration.

بررسی اثر مهار گیرنده رایانیدینی(RYR) بر فعالیت پیس‌میکری

    Background & Aim: The role of ryanodine receptor(RYR) on pacemaker activity of heart cells is controversial. Some investigators have suggested that it is obligatory, while others believe it is partial and not obligatory. The principle aim of this study was once more to characterize the role of ryanodine receptor(RyR) on the pacemaker activity of the sinoatrial node(SAN) and the atrioventric...

Perinatal loss of Nkx2-5 results in rapid conduction and contraction defects.

Homeobox transcription factor Nkx2-5, highly expressed in heart, is a critical factor during early embryonic cardiac development. In this study, using tamoxifen-inducible Nkx2-5 knockout mice, we demonstrate the role of Nkx2-5 in conduction and contraction in neonates within 4 days after perinatal tamoxifen injection. Conduction defect was accompanied by reduction in ventricular expression of t...

Regulation of cardiac excitation-contraction coupling: a cellular update.

The primary purpose of this paper is to present a basic overview of some "relatively" new ideas related to the regulation of cardiac performance and underlying excitation-contraction (EC) coupling that have yet to be incorporated to textbooks currently used for introductory graduate-level physiology courses. Within the context of cardiac EC coupling, this review incorporates information on micr...

Cardiac ryanodine receptor phosphorylation by CaM Kinase II: keeping the balance right.

Phosphorylation of the cardiac ryanodine receptor (RyR2) is a key mechanism regulating sarcoplasmic reticulum (SR) Ca2+ release. Differences in opinion have arisen over the importance assigned to specific phosphorylation sites on RyR2, over the kinase (s) suggested to directly phosphorylate RyR2 and surrounding the possibility that altered phosphorylation of RyR2 is associated with contractile ...

Role of RyR2 phosphorylation in heart failure and arrhythmias: Controversies around ryanodine receptor phosphorylation in cardiac disease.

Cardiac ryanodine receptor type 2 plays a key role in excitation-contraction coupling. The ryanodine receptor type 2 channel protein is modulated by various post-translational modifications, including phosphorylation by protein kinase A and Ca(2+)/calmodulin protein kinase II. Despite extensive research in this area, the functional effects of ryanodine receptor type 2 phosphorylation remain dis...
