International Journal of Biochemistry and Cell Biology, 2009 Summary Normal Ca2+ signalling in skeletal muscle depends on the membrane associated proteins triadin and junctin and their ability to mediate functional interactions between the Ca2+ binding protein calsequestrin and the type 1 ryanodine receptor in the

TMEM16A channel signalling microdomains in the regulation of vascular function
The Journal of Physiology, EarlyView.Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow
The Journal of Physiology, EarlyView.Abstract figure legend Pericytes are microvascular mural cells with diverse roles. Contractile pericytes directly regulate local perfusion, while non‐contractile pericytes coordinate upstream vascular contractility via propagating electrical signals.

Update on cellular expression and function of ANO1 channels in urethral smooth muscle
The Journal of Physiology, EarlyView.Abstract figure legend Activation of ANO1 channels and resulting Cl− efflux are suggested to modulate urethral smooth muscle contractility by enhancing Ca2+ influx via voltage‐dependent Ca2+ entry and resulting contraction in urethral smooth muscle cells.

The Journal of Physiology, EarlyView.Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...

FKBP12 Depletion Leads to Loss of Sarcoplasmic Reticulum Ca2+ Stores in Rat Vas Deferens
Journal of Pharmacological Sciences, 2009 The immunophilin 12-kDa FK506 binding protein (FKBP12) stabilizes intracellular Ca2+ release channel (CRC) activity in different tissues. In this work, the presence of FKBP12 in rat vas deferens (RVD) and its possible contribution to RVD function was ...

How to open a Ryanodine Receptor [PDF]
Cell Research, 2016 Ryanodine Receptors are large ion channels responsible for the release of Ca from the Endoplasmic and Sarcoplasmic Reticulum, a prerequisite for muscle contraction. Recent cryo-electron microscopy data have allowed a direct visualization of allosteric motions within these membrane protein giants.

Intramuscular pathways of maladaptation in overtraining syndrome
The Journal of Physiology, EarlyView.Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury
The Journal of Physiology, EarlyView.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 ...
