Impedance analysis of GPCR-mediated changes in endothelial barrier function: overview and fundamental considerations for stable and reproducible measurements
The past 20 years has seen significant growth in using impedance-based assays to understand the molecular underpinning of endothelial and epithelial barrier function in response to physiologicalExpand
Orai3 is an estrogen receptor α‐regulated Ca2+ channel that promotes tumorigenesis
Store‐operated Ca2+ entry (SOCE) encoded by Orai1 proteins is a ubiquitous Ca2+‐selective conductance involved in cellular proliferation and migration. We recently described up‐regulation of Orai3Expand
Endoplasmic Reticulum Stress Is Involved in Cardiac Damage and Vascular Endothelial Dysfunction in Hypertensive Mice
Objective—Cardiac damage and vascular dysfunction are major causes of morbidity and mortality in hypertension. In the present study, we explored the beneficial therapeutic effect of endoplasmicExpand
Involvement of Metalloproteinases 2/9 in Epidermal Growth Factor Receptor Transactivation in Pressure-Induced Myogenic Tone in Mouse Mesenteric Resistance Arteries
Background—Epidermal growth factor receptor (EGFR) transactivation is a mediator of angiotensin II (Ang II) signaling in cultured vascular smooth muscle cells isolated from large arteries. TheExpand
Mechanism of endoplasmic reticulum stress-induced vascular endothelial dysfunction.
BACKGROUND We recently reported that ER stress plays a key role in vascular endothelial dysfunction during hypertension. In this study we aimed to elucidate the mechanisms by which ER stressExpand
STIM1 and Orai1 mediate CRAC channel activity and are essential for human glioblastoma invasion
The Ca2+ sensor stromal interacting molecule 1 (STIM1) and the Ca2+ channel Orai1 mediate the ubiquitous store-operated Ca2+ entry (SOCE) pathway activated by depletion of internal Ca2+ stores andExpand
Store-Independent Orai1/3 Channels Activated by Intracrine LeukotrieneC4: Role in Neointimal Hyperplasia
Rationale: Through largely unknown mechanisms, Ca2+ signaling plays important roles in vascular smooth muscle cell (VSMC) remodeling. Orai1-encoded store-operated Ca2+ entry has recently emerged asExpand
Hydrogen peroxide acts as both vasodilator and vasoconstrictor in the control of perfused mouse mesenteric resistance arteries
Background Hydrogen peroxide (H2O2) plays a key role in the control of resistance artery (RA) tone and is hypothesized as an endothelial-derived hyperpolarizing factor. Methods In this study, weExpand
Angiotensin II Stimulates Extracellular Signal-Regulated Kinase Activity in Intact Pressurized Rat Mesenteric Resistance Arteries
The activation of extracellular signal–regulated kinases 1/2 (ERK1/2) was assessed in isolated rat mesenteric resistance arteries (200-&mgr;m diameter) in a pressure myograph and stimulated for 5Expand
STIM1 Controls Endothelial Barrier Function Independently of Orai1 and Ca2+ Entry
The calcium sensor STIM1 disrupts the endothelial barrier by coupling the thrombin receptor to the actin cytoskeleton. Breaking the Endothelial Barrier Thrombin is an endogenous ligand that inducesExpand
