Thrombin-induced barrier dysfunction of pulmonary endothelial monolayer is associated with dramatic cytoskeletal reorganization, activation of actomyosin contraction, and gap formation. Phosphorylation of regulatory myosin light chains (MLC) is a key mechanism of endothelial cell (EC) contraction and barrier dysfunction, which is triggered by(More)
Barrier dysfunction of pulmonary endothelial monolayer is associated with dramatic cytoskeletal reorganization, activation of actomyosin contractility, and gap formation. The linkage between the microtubule (MT) network and the contractile cytoskeleton has not been fully explored, however, clinical observations suggest that intravenous administration of(More)
Disturbances in endothelial cell (EC) barrier regulation are critically dependent upon rearrangements of EC actin cytoskeleton. However, the role of microtubule (MT) network in the regulation of EC permeability is not well understood. We examined involvement of MT remodeling in thrombin-induced EC permeability and explored MT regulation by heterotrimeric(More)
The question of how subdivision of embryo into cell territories acquiring different fates is coordinated with morphogenetic movements shaping the embryonic body still remains poorly resolved. In the present report, we demonstrate that a key regulator of anterior neural plate patterning, the homeodomain transcriptional repressor Xanf1/Hesx1, can bind to the(More)
