Organelle Optogenetics: Direct Manipulation of Intracellular Ca2+ Dynamics by Light

Frontiers in Neuroscience, 2018
As one of the ubiquitous second messengers, the intracellular Ca2+, has been revealed to be a pivotal regulator of various cellular functions. Two major sources are involved in the initiation of Ca2+-dependent signals: influx from the extracellular space

PI3Ks maintain the structural integrity of T-tubules in cardiac myocytes. [PDF]

PLoS ONE, 2011
Phosphoinositide 3-kinases (PI3Ks) regulate numerous physiological processes including some aspects of cardiac function. Although regulation of cardiac contraction by individual PI3K isoforms has been studied, little is known about the cardiac ...

Early changes in rat diaphragm biology with mechanical ventilation [PDF]

, 2003
To better characterize the effects of 24-hour mechanical ventilation on diaphragm, the expression of myogenic transcription factors, myosin heavy chains, and sarcoplasmic/endoplasmic reticulum calcium-ATPase pumps was examined in rats.

Adss1–HDAC3 Interaction: A Novel Mechanism for Epigenetic Regulation of Metabolism in Adipose Tissue

iNew Medicine, EarlyView.
ABSTRACT Obesity and its related metabolic disorders have emerged as global public health challenges with underlying mechanisms involving an imbalance between energy storage and expenditure in the adipose tissue. In recent years, with the deepening research on adipose tissue metabolism, the cross talk between metabolic enzymes and epigenetic regulation

Calcium sparks in arterial smooth muscle cells regulate vascular tone

Journal of Biological Research, 2002
It is named Ca2+ sparks a local, rapid and transient Ca2+ release from sarcoplasmic reticulum (SR) by the opening of ryanodine-sensitive (RyR) channels. RyR channels localized in SR are found in all muscle cell types (cardiac, skeletal, smooth) and many

Junctate is a key element in calcium entry induced by activation of InsP3 receptors and/or calcium store depletion [PDF]

, 2004
In many cell types agonist-receptor activation leads to a rapid and transient release of Ca(2+) from intracellular stores via activation of inositol 1,4,5 trisphosphate (InsP(3)) receptors (InsP(3)Rs).

VPS13A Deficiency Leads to Impaired Lipid Distribution and Alteration of Mitochondrial Calcium Homeostasis in Fibroblasts of VPS13A Disease Patients

Movement Disorders, EarlyView.
Abstract Background Membrane contact sites are crucial for the exchange of ions or lipids and thus are critical for the function and maintenance of organelles. VPS13A is a membrane‐residing, bridge‐like protein connecting two membranes to enable bulk lipid transfer. Loss‐of‐function mutations in the VPS13A gene cause VPS13A disease.

Investigating the protective role of the natural hormone Melatonin, in reducing drug-induced cardiotoxicity in the therapy of chronic diseases [PDF]

, 2019
Heart failure (HF) is a highly complex disorder and a major end-point of cardiovascular diseases (CVD). The pathogenesis of HF is mostly unresolved but involves interplay between cardiac structural and electrical remodelling, metabolic alterations, cell ...

Proteomic Profiling of Myofiber Repair Annexins and Their Role in Duchenne Muscular Dystrophy

PROTEOMICS, EarlyView.
ABSTRACT Myofiber regeneration and membrane repair play crucial roles in maintaining the continuous physiological functioning of the neuromuscular system. A swift and efficient repair mechanism enables the rapid restoration of sarcolemmal integrity following cellular impairment in damaged skeletal muscles.

Progressive Structural Defects in Canine Centronuclear Myopathy Indicate a Role for HACD1 in Maintaining Skeletal Muscle Membrane Systems [PDF]

, 2016
Mutations in HACD1/PTPLA cause recessive congenital myopathies in humans and dogs. Hydroxyacyl-coA dehydratases are required for elongation of very long chain fatty acids, and HACD1 has a role in early myogenesis, but the functions of this striated ...
