Type 2 ryanodine receptor: A novel therapeutic target in myocardial ischemia/reperfusion [PDF]

Pharmacology & Therapeutics, 2013
Cardiac pathologies remain the main cause of mortality worldwide. Among them the most common cause is cardiac ischemia. The rapid reperfusion after coronary occlusion has considerably improved the cardiac outcome, however reperfusion per se has deleterious effect also called reperfusion injuries.

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Diaphragm‐specific effects of L‐citrulline in mdx mice highlight its potential as adjuvant of standard therapy in Duchenne muscular dystrophy

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose The absence of the protein dystrophin in Duchenne muscular dystrophy (DMD) leads to progressive muscle weakness, failing regeneration and deregulation of nitric oxide (NO) signalling. We focused on L‐citrulline, a precursor of L‐arginine, required for NO production in muscle, which is reduced in dystrophic mdx muscle ...

A novel selective stabilizer of the ryanodine receptor 2 prevents stress‐induced ventricular arrhythmias without impairing cardiac function

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Aberrant activation of type 2 ryanodine receptors (RyR2) causes lethal arrhythmias, such as catecholaminergic polymorphic ventricular tachycardia (CPVT). Developing drugs that suppress RyR2 hyperactivation may be key to novel arrhythmia treatments.

A dual-targeted drug inhibits cardiac ryanodine receptor Ca 2+ leak but activates SERCA2a Ca 2+ uptake

Life Science Alliance
Our study identified a first multi-targeted compound (GM1869) inhibiting RyR2-mediated Ca 2+ leak together with activating SERCA2a function that may represent a critical breakthrough for treatment of diastolic Ca 2+ leak in heart failure.

ER proteostasis meets mitochondrial function: contact sites as hubs of communication and therapeutic targets

The FEBS Journal, EarlyView.
Proteostasis ensures proper protein folding, modification, and degradation, while its impairment triggers ER stress. Chronic ER stress and maladaptive UPR via the CHOP–ERO1 axis remodel ERMCs, altering calcium signaling and mitochondrial metabolism.

Molecular genetic analysis for malignant hyperthermia : a thesis presented to Massey University in partial fulfilment of the requirements for the degree of Master of Science in Biochemistry [PDF]

, 2004
Malignant hyperthermia (MH) is a rare pharmacogenetic disorder in humans caused by inhalational general anaesthetics and depolarising muscle relaxants. An MH reaction shows abnormal calcium homeostasis in skeletal muscle leading to a hypermetabolic state

Distance constraints on activation of TRPV4 channels by AKAP150-bound PKCα in arterial myocytes. [PDF]

, 2017
TRPV4 (transient receptor potential vanilloid 4) channels are Ca2+-permeable channels that play a key role in regulating vascular tone. In arterial myocytes, opening of TRPV4 channels creates local increases in Ca2+ influx, detectable optically as "TRPV4

Applying lessons from limb muscle disuse and ageing to better understand ventilator‐induced diaphragm dysfunction

Experimental Physiology, EarlyView.
Abstract Mechanical ventilation (MV) is a life‐saving intervention applied to critically ill patients. A common consequence of MV is ventilator‐induced diaphragm dysfunction (VIDD), which is characterized by significant diaphragm atrophy and reduced contractile function. Older patients who receive MV are more likely to develop VIDD, have worse recovery,

Characterization of Transepithelial Potential Oscillations in the \u3cem\u3eDrosophila\u3c/em\u3e Malpighian Tubule [PDF]

, 2001
The Malpighian tubule of Drosophila melanogaster is a useful model system for studying the regulation of epithelial ion transport. In acutely isolated tubules, the transepithelial potential (TEP) undergoes large oscillations in amplitude with a period of
