The mechanisms by which physical forces regulate endothelial cells to determine the complexities of vascular structure and function are enigmatic. Studies of sensory neurons have suggested Piezo proteins as subunits of Ca(2+)-permeable non-selective cationic channels for detection of noxious mechanical impact. Here we show Piezo1 (Fam38a) channels as(More)
BACKGROUND The annulus is a ring-shaped structure located beneath the plasma membrane that connects the midpiece and the principal piece of mammalian sperm flagellum. It has been suggested that the annulus acts as a morphological organizer, guiding flagellum assembly during spermiogenesis, and as a diffusion barrier, confining proteins to distinct(More)
OBJECTIVE Vascular endothelial growth factor (VEGF) acts, in part, by triggering calcium ion (Ca(2+)) entry. Here, we sought understanding of a Synta66-resistant Ca(2+) entry pathway activated by VEGF. APPROACH AND RESULTS Measurement of intracellular Ca(2+) in human umbilical vein endothelial cells detected a Synta66-resistant component of VEGF-activated(More)
