Catecholaminergic polymorphic ventricular tachycardia-linked ryanodine receptor variants exhibit domain-specific calcium leak and calmodulin affinity properties. [PDF]

open access: yesJ Physiol
Abstract figure legend Catecholaminergic polymorphic ventricular tachycardia (CPVT) variants in N terminal (NTD) and central domain (CD) but not pore domain induce a pathological RyR2 conformational shift upon protein kinase A (PKA) phosphorylation, similar to that seen in heart failure (HF), calcium/calmodulin‐dependent protein kinase II (CaMKII ...

The link between abnormalities of calcium handling proteins and catecholaminergic polymorphic ventricular tachycardia

open access: yesTzu Chi Medical Journal, 2021
Catecholaminergic polymorphic ventricular tachycardia (CPVT), a rare autosomal dominant or recessive disease, usually results in syncope or sudden cardiac death. Most CPVT patients do not show abnormal cardiac structure and electrocardiogram features and

Cell Deformation at the Air-Liquid Interface Evokes Intracellular Ca2+ Increase and ATP Release in Cultured Rat Urothelial Cells

open access: yesFrontiers in Physiology, 2021
Urothelial cells have been implicated in bladder mechanosensory transduction, and thus, initiation of the micturition reflex. Cell deformation caused by tension forces at an air-liquid interface (ALI) can induce an increase in intracellular Ca2 ...

Clinical and molecular characterization of a cardiac ryanodine receptor founder mutation causing catecholaminergic polymorphic ventricular tachycardia [PDF]

open access: yes, 2015
Background Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a difficult-to-diagnose cause of sudden cardiac death (SCD). We identified a family of 1400 individuals with multiple cases of CPVT, including 36 SCDs during youth.

Gene Transfer of Engineered Calmodulin Alleviates Ventricular Arrhythmias in a Calsequestrin-Associated Mouse Model of Catecholaminergic Polymorphic Ventricular Tachycardia [PDF]

open access: yes, 2018
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a familial arrhythmogenic syndrome characterized by sudden death. There are several genetic forms of CPVT associated with mutations in genes encoding the cardiac ryanodine receptor (RyR2 ...

Subcellular localization of hippocampal ryanodine receptor 2 and its role in neuronal excitability and memory

open access: yesCommunications Biology, 2022
A mouse model containing a GFP-tagged ryanodine receptor 2 (RyR2) has shed light on the precise subcellular localization of hippocampal RyR2 and mechanisms underlying neuronal excitability, learning, and memory.

The Mitochondrial Ca(2+) Uniporter: Structure, Function, and Pharmacology. [PDF]

open access: yes, 2017
Mitochondrial Ca(2+) uptake is crucial for an array of cellular functions while an imbalance can elicit cell death. In this chapter, we briefly reviewed the various modes of mitochondrial Ca(2+) uptake and our current understanding of mitochondrial Ca(2+)

Chronic dantrolene treatment attenuates cardiac dysfunction and reduces atrial fibrillation inducibility in a rat myocardial infarction heart failure modelKey Findings

open access: yesHeart Rhythm O2, 2020
Background: Cardiac ryanodine receptor 2 (RyR2) dysfunction and elevated diastolic Ca2+ leak have been linked to arrhythmogenesis not only in inherited arrhythmia syndromes but also in acquired forms of heart disease including heart failure (HF) and ...

Ryanodine receptors are targeted by anti-apoptotic Bcl-X-L involving its BH4 domain and Lys87 from its BH3 domain [PDF]

open access: yes, 2015
Anti-apoptotic B-cell lymphoma 2 (Bcl-2) family members target several intracellular Ca2+-transport systems. Bcl-2, via its N-terminal Bcl-2 homology (BH) 4 domain, inhibits both inositol 1,4,5-trisphosphate receptors (IP(3)Rs) and ryanodine receptors ...

Neferine induces autophagy-dependent cell death in apoptosis-resistant cancers via ryanodine receptor and Ca2+-dependent mechanism

open access: yesScientific Reports, 2019
Resistance of cancer cells to chemotherapy is a significant clinical concern and mechanisms regulating cell death in cancer therapy, including apoptosis, autophagy or necrosis, have been extensively investigated over the last decade.
