Macrophage-mediated IL-6 signaling drives ryanodine receptor–2 calcium leak in postoperative atrial fibrillation [PDF]
Postoperative atrial fibrillation (poAF) is AF occurring days after surgery, with a prevalence of 33% among patients undergoing open-heart surgery. The degree of postoperative inflammation correlates with poAF risk, but less is known about the cellular ...

A circular RNA derived from the ryanodine receptor 2 locus controls cardiac hypertrophy and calcium handling [PDF]
Heart failure (HF) is a leading cause of mortality worldwide, characterized by structural and functional alterations that result in reduced cardiac function. During the progression of HF, cardiomyocytes undergo profound remodeling – including development

Insights into the gating mechanism of the ryanodine-modified human cardiac Ca2+-release channel (ryanodine receptor 2). [PDF]
Ryanodine receptors (RyRs) are intracellular membrane channels playing key roles in many Ca(2+) signaling pathways and, as such, are emerging novel therapeutic and insecticidal targets. RyRs are so named because they bind the plant alkaloid ryanodine with high affinity and although it is established that ryanodine produces profound changes in all ...

S100A1 DNA-based Inotropic Therapy Protects Against Proarrhythmogenic Ryanodine Receptor 2 Dysfunction. [PDF]
Restoring expression levels of the EF-hand calcium (Ca(2+)) sensor protein S100A1 has emerged as a key factor in reconstituting normal Ca(2+) handling in failing myocardium. Improved sarcoplasmic reticulum (SR) function with enhanced Ca(2+) resequestration appears critical for S100A1's cyclic adenosine monophosphate-independent inotropic effects but ...

MYBPC3 (c.194 C > T) mutation-mediated RyR2 dysfunction contributes to pathogenic phenotypes of DCM revealed by HiPSC modeling [PDF]
Dilated cardiomyopathy (DCM) is a leading cause of heart failure and the primary indication for heart transplantation. The intricate and poorly elucidated pathogenesis of genetic DCM, coupled with the paucity of effective therapeutic options, imposes a ...

Ryanodine receptor‐2 upregulation and nicotine‐mediated plasticity [PDF]
Nicotine, the major psychoactive component of cigarette smoke, modulates neuronal activity to produce Ca2+-dependent changes in gene transcription. However, the downstream targets that underlie the long-term effects of nicotine on neuronal function, and hence behaviour, remain to be elucidated.

Ryanodine Sensitizes the Ca2+ Release Channel (Ryanodine Receptor) to Ca2+ Activation [PDF]
Ryanodine, a plant alkaloid, is one of the most widely used pharmacological probes for intracellular Ca(2+) signaling in a variety of muscle and non-muscle cells. Upon binding to the Ca(2+) release channel (ryanodine receptor), ryanodine causes two major changes in the channel: a reduction in single-channel conductance and a marked increase in open ...

Recent evidence suggests that the reason Extra Virgin Olive Oil (EVOO) lowers blood pressure and reduces the risk of developing hypertension is partly due to minor components of EVOO, such as phenols. However, little is still known about the mechanism(s)

Bcl-2 binds to and inhibits ryanodine receptors [PDF]
The anti-apoptotic B-cell lymphoma-2 (Bcl-2) protein not only counteracts apoptosis at the mitochondria by scaffolding pro-apoptotic Bcl-2-family members, but also acts at the endoplasmic reticulum, thereby controlling intracellular Ca2+ dynamics. Bcl-2 inhibits Ca2+ release by targeting the inositol 1,4,5-trisphosphate receptor (IP3R).
