A two-phase response of endothelial cells to hydrostatic pressure

Abstract: The vascular endothelium is exposed to three types of mechanical forces: blood flow-mediated shear stress, vessel diameter-dependent wall tension and hydrostatic pressure. Despite considerable variations of blood pressure during normal and pathological physiology, little is known about the acute molecular and cellular effects of hydrostatic pressure on endothelial cells. Here, we used a combination of quantitative fluorescence microscopy, atomic force microscopy and molecular perturbations to characterize the … Show more

“…As super-resolution imaging in the zebrafish embryo is technically difficult, we investigated whether Marcksl1 alters cortical actin organisation in HUVECs in culture. Like in zebrafish ECs and in a previous finding 19 , we also detected a meshwork of actin cytoskeleton at the apical cell cortex (Fig. 8b ).…”

“…We did not observe any changes in total cellular MYL2 phosphorylation in Western blot, which is in line with our work on endothelial cells (Prystopiuk et al, 2018). This phenomenon argues for localized phosphorylation of myosin light chains in the cell cortical area.…”

“…1b, c, e and f). This finding is consistent with a previous report that demonstrated an increase in the density of actin and activated phosphorylated myosin light chain at the EC cortex after chronic exposure to elevated hydrostatic pressure 19 . These observations therefore suggest ECs become stiffer after exposure to blood flow.…”
