Ryanodine receptors are large channels that release Ca2+ from the endoplasmic and sarcoplasmic reticulum. Hundreds of RyR mutations can cause cardiac and skeletal muscle disorders, yet detailed mechanisms explaining their effects have been lacking.

Mathematical model of the zebrafish ventricular cardiomyocyte action potential and calcium transient
Abstract figure legend This study presents the development and validation of the first biophysically detailed computational model of the zebrafish ventricular action potential (AP). The model is based on a human cardiomyocyte framework and reparameterized using published and newly generated patch‐clamp recordings of zebrafish ionic currents.

The organisation and functions of local Ca2+ signals [PDF]
Calcium (Ca2+) is a ubiquitous intracellular messenger, controlling a diverse range of cellular processes, such as gene transcription, muscle contraction and cell proliferation.

Inhibition of NAADP signalling on reperfusion protects the heart by preventing lethal calcium oscillations via two-pore channel 1 and opening of the mitochondrial permeability transition pore [PDF]
Aims In the heart, a period of ischaemia followed by reperfusion evokes powerful cytosolic Ca2+ oscillations that can cause lethal cell injury. These signals represent attractive cardioprotective targets, but the underlying mechanisms of genesis are ill ...

In Alzheimer disease (AD), the perturbation of the endoplasmic reticulum (ER) calcium (Ca2+) homeostasis has been linked to presenilins, the catalytic core in γ-secretase complexes cleaving the amyloid precursor protein (APP), thereby generating amyloid ...

Abstract figure legend Calciprotein particles (CPPs) are small calcium‐ and phosphate‐containing nanoaggregates associated with the development of vascular disease (CVD) in chronic kidney disease (CKD). Previously, we have shown that CPPs induce endothelial cell (EC) dysfunction, possibly contributing to CVD in CKD, but the underlying molecular ...

PCB-95 Promotes Dendritic Growth via Ryanodine Receptor–Dependent Mechanisms
Background: Aroclor 1254 (A1254) interferes with normal dendritic growth and plasticity in the developing rodent brain, but the mechanism(s) mediating this effect have yet to be established.

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...
