Fluidic force microscopy and atomic force microscopy are used to investigate the interaction of preosteoblast cells with patterned surfaces having different pillar heights. The results reveal differences in cell adhesion strength, settling state, cytoskeleton reorganization and local elastic modulus between the cells adhered on the two different ...

Rho GTPases and their downstream effectors in megakaryocyte biology
Megakaryocytes differentiate from hematopoietic stem cells in the bone marrow. The transition of megakaryocytes to platelets is a complex process. Thereby, megakaryocytes extend proplatelets into sinusoidal blood vessels, where the proplatelets undergo ...

RhoA Proteolysis Regulates the Actin Cytoskeleton in Response to Oxidative Stress. [PDF]
The small GTPase RhoA regulates the actin cytoskeleton to affect multiple cellular processes including endocytosis, migration and adhesion. RhoA activity is tightly regulated through several mechanisms including GDP/GTP cycling, phosphorylation ...

RhoA as a Key Regulator of Innate and Adaptive Immunity
RhoA is a ubiquitously expressed cytoplasmic protein that belongs to the family of small GTPases. RhoA acts as a molecular switch that is activated in response to binding of chemokines, cytokines, and growth factors, and via mDia and the ROCK signaling ...

Phosphorylation and Activation of RhoA by ERK in Response to Epidermal Growth Factor Stimulation. [PDF]
The small GTPase RhoA has been implicated in various cellular activities, including the formation of stress fibers, cell motility, and cytokinesis. In addition to the canonical GTPase cycle, recent findings have suggested that phosphorylation further ...

RhoA promotes epidermal stem cell proliferation via PKN1-cyclin D1 signaling. [PDF]
OBJECTIVE:Epidermal stem cells (ESCs) play a critical role in wound healing, but the mechanism underlying ESC proliferation is not well defined. Here, we explore the effects of RhoA on ESC proliferation and the possible underlying mechanism.

RhoA mediates epithelial cell shape changes via mechanosensitive endocytosis
Morphogenetic movements require tight spatiotemporal control over cell-cell junction lengths. Contractile forces, acting at adherens junctions, alter cell-cell contact lengths in a cyclic fashion as a mechanical ratchet.

Protein Kinase C-related Kinase and ROCK Are Required for Thrombin-induced Endothelial Cell Permeability Downstream from G{alpha}12/13 and G{alpha}11/q [PDF]
Increase in vascular permeability occurs under many physiological conditions and is central in diverse human pathologies. Thrombin is a pro-coagulant serine protease, which causes the local loss of endothelial barrier integrity thereby enabling the rapid extravasation of plasma proteins and the local formation of fibrin-containing clots.
