The role of ryanodine receptors in development [PDF]

open access: yes, 2011
PhDCalcium ions (Ca2+) are fundamental to the regulation of many cellular processes; however, the coordination of these signals during embryogenesis is not well understood.

Single Amino Acid Changes in the Ryanodine Receptor in the Human Population Have Effects In Vivo on Caenorhabditis elegans Neuro-Muscular Function

open access: yesFrontiers in Genetics, 2020
The ryanodine receptor mediates intracellular calcium ion release with excitation of nerve and muscle cells. Ryanodine receptor missense variants cause a number of myopathologies, such as malignant hyperthermia, and have been linked with various ...

Functional characterization of the cardiac ryanodine receptor pore-forming region. [PDF]

open access: yesPLoS ONE, 2013
Ryanodine receptors are homotetrameric intracellular calcium release channels. The efficiency of these channels is underpinned by exceptional rates of cation translocation through the open channel and this is achieved at the expense of the high degree of

Excitation Contraction Coupling in Hypertrophy and Failing Heart Cells [PDF]

open access: yesE3S Web of Conferences, 2021
The contraction of the heart is dependent on a process named the excitation-contraction coupling (E-C coupling). In hypertrophy and failing heart models, the expression, phosphorylation and function of key calcium handling proteins involved in E-C ...

Hypernitrosylated ryanodine receptor calcium release channels are leaky in dystrophic muscle [PDF]

open access: yesNature Medicine, 2009
Duchenne muscular dystrophy is characterized by progressive muscle weakness and early death resulting from dystrophin deficiency. Loss of dystrophin results in disruption of a large dystrophin glycoprotein complex, leading to pathological calcium (Ca2+)-dependent signals that damage muscle cells. We have identified a structural and functional defect in

The Builders of the Junction: Roles of Junctophilin1 and Junctophilin2 in the Assembly of the Sarcoplasmic Reticulum–Plasma Membrane Junctions in Striated Muscle

open access: yesBiomolecules, 2022
Contraction of striated muscle is triggered by a massive release of calcium from the sarcoplasmic reticulum (SR) into the cytoplasm. This intracellular calcium release is initiated by membrane depolarization, which is sensed by voltage-gated calcium ...

Current clinical application of dantrolene sodium [PDF]

open access: yesAnesthesia and Pain Medicine, 2023
Dantrolene sodium (DS) was first introduced as an oral antispasmodic drug. However, in 1975, DS was demonstrated to be effective for managing malignant hyperthermia (MH) and was adopted as the primary therapeutic drug after intravenous administration ...

ATP- and Adenosine-Mediated Signaling in the Central Nervous System: Adenosine Stimulates Glutamate Release From Astrocytes via A2a Adenosine Receptors

open access: yesJournal of Pharmacological Sciences, 2004
Adenosine enhanced intracellular Ca2+ concentrations in astrocytes via A2a adenosine receptors involving protein kinase A (PKA) activation. The Ca2+ rise is inhibited by brefeldin A, an inhibitor of vesicular transport; but not by neomycin and U73122 ...

Calcium homeostasis and role of ryanodine receptor type 1 (RyR1) in immune cells [PDF]

open access: yes, 2010
Ryanodine receptors are intracellular Ca2+ release channels located in the membrane of the Endoplasmatic/Sarcoplasmatic Reticulum. Ryanodine receptor 1 isoform is preferentially expressed in skeletal muscle where it is responsible for release of Ca2 ...

Snapin, positive regulator of stimulation- induced Ca²⁺ release through RyR, is necessary for HIV-1 replication in T cells. [PDF]

open access: yesPLoS ONE, 2013
To identify critical host factors necessary for human immunodeficiency virus 1 (HIV-1) replication, large libraries of short-peptide-aptamers were expressed retrovirally.
