Structural heterogeneity of the ion and lipid channel TMEM16F

Transmembrane protein 16 F (TMEM16F) is a Ca2+-activated homodimer which functions as an ion channel and a phospholipid scramblase. Despite the availability of several TMEM16F cryogenic electron microscopy (cryo-EM) structures, the mechanism of activation ...

Acute RyR1 Ca2+ leak enhances NADH-linked mitochondrial respiratory capacity

Johan Auwerx, Umberto De Marchi

Sustained ryanodine receptor (RyR) Ca2+ leak is associated with pathological conditions such as heart failure or skeletal muscle weakness. We report that a single session of sprint interval training (SIT), but not of moderate intensity continuous training ...

Zinc complexation improves angiotensin II receptor type 1 blockade and in vivo antihypertensive activity of telmisartan

Nikolaos Stergiopoulos, Augusto Martins Lima, Valeria Romina Martinez

Background: Angiotensin II receptor blockers were designed as therapeutic agents to block the binding site of the angiotensin II receptor type 1 (AT1R). Methodology: The structure of telmisartan was modified by coordination to the biometal Zn(II), resultin ...

Triclosan Impairs Swimming Behavior and Alters Expression of Excitation-Contraction Coupling Proteins in Fathead Minnow (Pimephales promelas)

Triclosan (TCS), a high volume chemical widely used in consumer products, is a known aquatic contaminant found in fish inhabiting polluted watersheds. Mammalian studies have recently demonstrated that TCS disrupts signaling between the ryanodine receptor ( ...

Ultrafast Ca2+ wave in cultured vascular smooth muscle cells aligned on a micropatterned surface

Jean-Jacques Meister, Jean-Louis Bény, Benoît Vianay, Jairo Camilo Quijano Perez

Communication between vascular smooth muscle cells (SMCs) allows control of their contraction and so regulation of blood flow. The contractile state of SMCs is regulated by cytosolic Ca2+ concentration (Ca2+) which propagates as Ca2+ waves over a sign ...

Intercellular ultrafast calcium wave in vascular smooth muscle cells

Jairo Camilo Quijano Perez

Communication between vascular smooth muscle cells (SMCs) allows control of their contraction and so regulation of blood flow. The contractile state of SMCs is controled by cytosolic Ca2+ concentration ([Ca2+]i) which propagates as Ca2+ waves over a signif ...

Functionalized 3D 7x20-array of vertically stacked SiNW FET for streptavidin sensing

Mihai Adrian Ionescu, Montserrat Fernandez-Bolanos Badia, Elizabeth Buitrago Godinez

A 3D, vertically stacked silicon nanowire (SiNW) field effect transistor (FET) featuring a high density array (7×20) of fully depleted channels has been successfully fabricated by a CMOS compatible process on silicon on insulator (SOI) and functionalized f ...

Intercellular calcium waves in primary cultured rat mesenteric smooth muscle cells are mediated by Connexin43

Jean-Jacques Meister, Jean-Louis Bény, Nadia Halidi

Intercellular Ca2+ wave propagation between vascular smooth muscle cells (SMCs) is associated with the propagation of contraction along the vessel. Here, we characterize the involvement of gap junctions (GJs) in Ca2+ wave propagation between SMCs at the ce ...
