Modulation of Rac1 activity by ADMA/DDAH regulates pulmonary endothelial barrier function.
Endogenously produced nitric oxide synthase inhibitor, asymmetric methylarginine (ADMA) is associated with vascular dysfunction and endothelial leakage. We studied the role of ADMA, and the enzymes metabolizing it, dimethylarginine dimethylaminohydrolases (DDAH) in the regulation of endothelial barrier function in pulmonary macrovascular and microvascular cells in vitro and in lungs of genetica...
متن کاملRhoGDI-1 modulation of the activity of monomeric RhoGTPase RhoA regulates endothelial barrier function in mouse lungs.
Rho family GTPases have been implicated in the regulation of endothelial permeability via their actions on actin cytoskeletal organization and integrity of interendothelial junctions. In cell culture studies, activation of RhoA disrupts interendothelial junctions and increases endothelial permeability, whereas activation of Rac1 and Cdc42 enhances endothelial barrier function by promoting the f...
متن کاملWild‐type p53 enhances endothelial barrier function by mediating RAC1 signalling and RhoA inhibition
Inflammation is the major cause of endothelial barrier hyper-permeability, associated with acute lung injury and acute respiratory distress syndrome. This study reports that p53 "orchestrates" the defence of vascular endothelium against LPS, by mediating the opposing actions of Rac1 and RhoA in pulmonary tissues. Human lung microvascular endothelial cells treated with HSP90 inhibitors activated...
متن کاملCaveolin-1 Regulates Rac1 Activation and Rat Pulmonary Microvascular Endothelial Hyperpermeability Induced by TNF-α
A multiplicity of vital cellular and tissue level functions are controlled by caveolin-1 and it is considered to be an important candidate for targeted therapeutics. Rac1-cortactin signaling plays an important role in maintaining the functions of the endothelial barrier in microvascular endothelial cells. The activity of Rac1 has been shown to be regulated by caveolin-1. Therefore, the present ...
متن کاملCdc42 regulates the restoration of endothelial barrier function.
The mechanisms involved in the restoration of endothelial cell junctions subsequent to barrier disruption remain unclear. It is known that formation of adherens junctions (AJs) affects cytoskeletal actin arrangement and that Rho GTPases regulate the state of actin polymerization. In the present study, we examined the role of the Rho GTPases, Rho, Rac, and Cdc42 in the reannealing of AJs. We stu...
