N2 - Restenosis after angioplasty still remains a major problem for which neointimal formation appears to play an important role. Recent studies in vitro suggested that Rho kinase, a target protein of Rho, is important in various cellular functions. We thus examined whether Rho kinase is involved in the restenotic changes after balloon injury. In vivo gene transfer was performed immediately after balloon injury in both sides of the porcine femoral arteries with adenoviral vector encoding either a dominant negative form of Rho kinase (AdDNRhoK) or β-galactosidase (AdLacZ) as a control. One week after the transfer, ...

Rho GTPases are master regulators of many immunoreceptors, ranging from receptors required for differentiation and maturation of immune cells and for pathogen recognition to receptors involved in pathogen uptake and the subsequent host signaling responses. Several TLRs induce the activation of the Rho family GTPases Rac, Rho, and Cdc42. Almost every cell type, including professional innate immune cells such as macrophages, neutrophils, and dendritic cells, responds to TLR stimulation by activating Rho GTPases rapidly (8, 20, 31). Similarly, lung epithelial cells induce Rho GTPase activation when they encounter TLR ligands. It seems apparent that RhoA activation depends on the interaction of a specific TLR ligand with its cognate TLR, independently of the connecting adapters or the cellular compartment where TLR signaling occurs. A RhoA FRET probe was used to examine localized RhoA activity at early time points after initiation of TLR2 or TLR3 signaling. After 3-5 min of treatment with the TLR2 ...
Several studies have identified Rho family GTPases (i.e. Rho, Rac, Cdc42) as mediators of diverse critical cellular processes, such as actin cytoskeleton remodeling, gene transcription, cell-cell adhesion, and cell cycle progression. However, more recent data highlight an essential role for Rho GTPases as regulators of neuronal morphology and neuronal survival. In particular, Rac GTPase generally induces neurite outgrowth and promotes neuronal survival while Rho GTPase typically provokes neurite retraction and induces neuronal apoptosis. However, the precise signaling pathways that regulate neuronal survival downstream of Rho GTPases and the potential involvement of dysregulated activity of Rho GTPases as a causative factor in the progression of neurodegenerative diseases remains to be elucidated. Consistent with a pro-survival function for Rac in neurons, inhibition of Rac with Clostridium difficle toxin B (ToxB) or expression of a dominant negative Rac1 mutant significantly induces activation of the

Rho small GTPases are conserved molecular switches in eukaryotic signal transduction involved in a variety of biological processes such as the establishment of cell polarity and actin remodeling. The GTPase switch is closely controlled through regulatory mechanism involving at least two kinds of negative regulators: ...

AIMS: Cyclooxygenase (COX)-2 expression is increased in inflammation and angiogenesis and also in atherosclerotic plaques, where it co-localizes with metalloproteinases (MMPs) involved in the fibrous cap weakening. Insight into the regulation of COX-2 and MMP-9 expression suggests the involvement of a Rho-dependent pathway. Because statins interfere with Rho activation, we investigated the statin effect on COX-2 and MMP expressions in the human endothelium. METHODS AND RESULTS: Simvastatin and atorvastatin were incubated with endothelial cells for 12 h before stimulation with phorbol myristate acetate or tumour necrosis factor-alpha, for times suitable to assess the endothelial tube differentiation on Matrigel and COX-2 and MMPs activities, proteins, and mRNA expressions. At 0.1-10 micromol/L, both statins reduced COX-2 expression and activity, without affecting COX-1. The statin effect was reversed by mevalonate and geranylgeranyl-pyrophosphate and mimicked by the Rho inhibitor C3 transferase, ...
Rho GTPases comprise a family of molecular switches that control signal transduction pathways in eukaryotic cells. A conformational change induced upon binding GTP promotes an interaction with target (effector) proteins to generate a cellular response. A highly conserved function of Rho GTPases from yeast to humans is to control the actin cytoskeleton, although, in addition, they promote a wide range of other cellular activities. Changes in the actin cytoskeleton drive many dynamic aspects of cell behaviour, including morphogenesis, migration, phagocytosis and cytokinesis, and the dysregulation of Rho GTPases is associated with numerous human diseases and disorders. ...
Although it is well understood that Rho GTPase activity is regulated by GEFs, very little is known about the specific role GEFs play in regulating cellular processes, such as migration. Our results show that Asef2 coordinately regulates the activities of Rho family members to promote cell migration by stimulating the rapid turnover of adhesions. Asef2 signaling leads to an overall decrease in the amount of active RhoA, which is crucial for the effect of Asef2 on migration. RhoA induces the formation of stress fibers and can promote the maturation of nascent cell-matrix contacts into large, focal adhesions (Chrzanowska-Wodnicka and Burridge, 1996; Ridley and Hall, 1992; Rottner et al., 1999). Thus, the loss of RhoA activity in GFP-Asef2 stable cells could inhibit the maturation of nascent adhesions and contribute to the more rapid turnover of these structures. These described activities of Rho would be expected to inhibit migration. Indeed, in some cell types, high levels of Rho have been shown ...
Generation and validation of RhoBTB1IND. Full-length RhoBTB1 was amplified from heart cDNA from C57BL/6J mice using the primers 5′-GCATGAACTAGTATGGACTCTGACATGGACTACGAACGAC-3′ (forward) and 5′-CATGAACTAGTTCAGGCGACAGCTGGGGACGAAT-3′ (reverse), with SpeI restriction enzyme sites inserted. RhoBTB1 cDNA was digested with SpeI and then subcloned into a previously described vector carrying the CAG promoter/enhancer, the loxP-STOP-loxP sequence, and IRES-tdTomato (53, 54). The construct was sequenced to confirm RhoBTB1 insertion and determine its orientation. The function of the RhoBTB1IND construct was tested in HEK293T cell lines. HEK293T cells plated in 6-well dishes were transfected using Lipofectamine LTX (Invitrogen, Thermo Fisher Scientific) according to the manufacturers protocol with either a Myc-RhoBTB1 or RhoBTB1IND construct with or without a plasmid encoding Cre recombinase (p185-Cre). Control transfections contained the inducible construct backbone with or without p185-Cre. The ...

and keywords: During metastasis, cancer cells can invade the extracellular matrix using various strategies. When invading individually, they employ either the amoeboid invasion mode, during which the cell body dynamically deforms by enhanced contractility to squeeze through pores within the matrix, or protease dependent mesenchymal migration that takes advantage of the possibility to digest the surrounding matrix. Cells migrating in one mode can actively switch to the other by mesenchymal-amoeboid (MAT) or amoeboid-mesenchymal transitions (AMT). This enables escape mechanisms and considerably complicates anti-metastatic treatment. It is well known that Rho GTPases are master regulators of cytoskeleton re-arrangements and thus, unsurprisingly, play a major role in both invasion modes and can directly drive the transitions. However, upstream activation of these pathways is still largely unclear. This thesis aimed to optimize 3D conditions suitable for studying plasticity of cell invasion in vitro, ...

Rho GTPases are a family of molecular switches that critically mediate many cellular processes such as proliferation, survival, and death. The most well described members of the Rho GTPase family are RhoA, Rac1, and Cdc42 which are each known to regulate actin cytoskeletal dynamics. Thus, it is not surprising that Rho GTPases play a crucial function in neuronal growth cone dynamics and dendritic spine morphogenesis. Specifically, Rac1 and Cdc42 generally induce neurite outgrowth and dendritic spine morphogenesis, while RhoA typically stimulates neurite retraction. In addition to regulating neuronal cytoskeletal dynamics, previous work has demonstrated a critical function for Rho GTPase family members in neuronal development and survival. Indeed, dysregulation of Rho GTPase family members has been implicated in several disorders of the central nervous system including, Down Syndrome, Fragile X Mental Retardation Syndrome, Amyotrophic Lateral Sclerosis, amongst many others. In addition to typical Rho
Rho GTPases are molecular switches that regulate many aspects of cell physiology. A number of Rho GTPases are essential for the formation of new vessels from pre-existing ones, a process known as angiogenesis. RhoJ/TCL belongs to the Cdc42 subfamily of Rho GTPases. Previous bioinformatic and primary cell line analyses identified RhoJ as being highly expressed in endothelial cells. The aim of this project was to investigate the expression pattern and endothelial function of RhoJ, particularly in the processes necessary for angiogenesis. Silencing RhoJ with siRNA impaired tube formation and migration. On the cellular level, RhoJ knockdown increased focal adhesions, actin stress fibres and collagen gel contraction, suggesting increased actomyosin contractility. Pharmacological inhibition of ROCK and myosin II, two regulators of actomyosin contractility, restored motility and tube formation after RhoJ knockdown. RhoJ localised to blood vessels of developing mice and in various human normal and ...
rho GTP-Binding Proteins: A large family of MONOMERIC GTP-BINDING PROTEINS that are involved in regulation of actin organization, gene expression and cell cycle progression. This enzyme was formerly listed as EC 3.6.1.47.
The Rho family of GTPases is a family of small (~21 kDa) signaling G proteins, and is a subfamily of the Ras superfamily. The members of the Rho GTPase family have been shown to regulate many aspects of intracellular actin dynamics, and are found in all eukaryotic kingdoms, including yeasts and some plants. Three members of the family have been studied in detail: Cdc42, Rac1, and RhoA. All G proteins are "molecular switches", and Rho proteins play a role in organelle development, cytoskeletal dynamics, cell movement, and other common cellular functions. Identification of the Rho family of GTPases began in the mid-1980s. The first identified Rho member was RhoA, isolated serendipitously in 1985 from a low stringency cDNA screening. Rac1 and Rac2 were identified next, in 1989 followed by Cdc42 in 1990. Eight additional mammalian Rho members were identified from biological screenings until the late 1990s, a turning point in biology where availability of complete genome sequences allowed full ...
Rho family GTPase subfamily Rnd includes Rnd1/Rho6, Rnd2/Rho7, and Rnd3/RhoE/Rho8. The Rnd subfamily contains Rnd1/Rho6, Rnd2/Rho7, and Rnd3/RhoE/Rho8. These novel Rho family proteins have substantial structural differences compared to other Rho members, including N- and C-terminal extensions relative to other Rhos. Rnd3/RhoE is farnesylated at the C-terminal prenylation site, unlike most other Rho proteins that are geranylgeranylated. In addition, Rnd members are unable to hydrolyze GTP and are resistant to GAP activity. They are believed to exist only in the GTP-bound conformation, and are antagonists of RhoA activity. Most Rho proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid. Lipid binding is essential for membrane attachment, a key feature of most Rho proteins. Due to the presence of truncated sequences in this CD, the lipid modification site is not available for annotation. ...
The strict spatio-temporal control of Rho GTPases is critical for many cellular functions, including cell motility, contractility, and growth. In this regard, the prototypical Rho family GTPases, Rho, Rac, and Cdc42 regulate the activity of each other by a still poorly understood mechanism. Indeed, we found that constitutively active forms of Rac inhibit stress fiber formation and Rho stimulation by thrombin. Surprisingly, a mutant of Rac that is unable to activate Pak1 failed to inhibit thrombin signaling to Rho. To explore the underlying mechanism, we investigated whether Pak1 could regulate guanine nucleotide exchange factors (GEFs) for Rho. We found that Pak1 associates with P115-RhoGEF but not with PDZ-RhoGEF or LARG, and knock down experiments revealed that P115-RhoGEF plays a major role in signaling from thrombin receptors to Rho in HEK293T cells. Pak1 binds the DH-PH domain of P115-RhoGEF, thus suggesting a mechanism by which Rac stimulation of Pak1 may disrupt receptor-dependent Rho signaling.

In biology, small GTPases are small (20-25 kDa) proteins that bind to guanosine triphosphate (GTP). This family of proteins is homologous to Ras GTPases and also called the Ras superfamily GTPases. Together with heterotrimeric G-proteins they constitute the G-proteins. They are all GTPases and share common features, but small GTPases have slightly different structures and mechanisms of action. A typical G-protein is active when bound to GTP and inactive when bound to GDP (i.e. when the GTP is hydrolyzed to GDP). The GDP can be then replaced by free GTP. Therefore, a G-protein can be switched on and off. GTP hydrolysis is accelerated by GTPase accelating proteins (GAPs), while GTP exchange is catalyzed by Guanine nucleotide exchange factors (GEFs). Activation of a GEF typically activates its cognate G-protein, while activation of a GAP results in inactivation of the cognate G-protein. Small GTPases regulate a wide variety of processes in the cell, including growth, cellular differentiation, cell ...

Ect2 is a guanine nucleotide exchange factor (GEF) and activator of Rho family small GTPases. Ect2 regulates RhoA, Rac1, and Cdc42, thereby playing an important role in the control of cell proliferation, survival, and migration. Originally identified as an oncogene in vitro, the role of Ect2 in regulating migration makes it of particular interest in ovarian cancer, in which local invasion and ascites are prevalent. Notably, ECT2 is located on 3q26.1-3q26.2, the most frequent amplicon in ovarian cancer, and it has been found to be overexpressed at the mRNA level in ovarian tumors. We first explored the role of Ect2 in ovarian cancer by knocking it down using shRNA and assessing anchorage-independent growth and both random and directed migration in a panel of ovarian cancer cell lines. Our findings reveal that Ect2 expression is required for each of these functions. Interestingly, we found that Ect2 utilization of specific Rho GTPase substrates is highly context-dependent. In addition, to ...

β2 integrins of neutrophils play a critical role in innate immune defense, but they also participate in tissue destruction during autoimmune inflammation. p190RhoGAP (ArhGAP35), a regulator of Rho family small GTPases, is required for integrin signal transduction in fibroblasts. Prior studies have also suggested a role for p190RhoGAP in β2 integrin signaling in neutrophils. To directly test that possibility, we have generated a novel targeted mutation completely disrupting the p190RhoGAP-encoding gene in mice. p190RhoGAP deficiency led to perinatal lethality and defective neural development, precluding the analysis of neutrophil functions in adult p190RhoGAP−/− animals. This was overcome by transplantation of fetal liver cells from p190RhoGAP−/− fetuses into lethally irradiated wild-type recipients. Neutrophils from such p190RhoGAP−/− bone marrow chimeras developed normally and expressed normal levels of various cell surface receptors. Although p190RhoGAP−/− neutrophils showed ...
Inflammatory immune response requires the recruitment of leukocytes to the site of inflammation upon foreign insult. Chemokines are small chemoattractant peptides that provide directional cues for the cell trafficking and thus are vital for protective host response. In addition, chemokines regulate plethora of biological processes of hematopoietic cells to lead cellular activation, differentiation and survival. The chemokine signal is transduced by chemokine receptors (G-protein coupled receptors) expressed on the immune cells. After receptor activation, the alpha- and beta-gamma-subunits of G protein dissociate to activate diverse downstream pathways resulting in cellular polarization and actin reorganization. Various members of small GTPases are involved in this process. Induction of nitric oxide and production of reactive oxygen species are as well regulated by chemokine signal via calcium mobilization and diacylglycerol production ...

Rho GTPases are overexpressed in a variety of human tumors contributing to both tumor proliferation and metastasis. Recently, several studies demonstrate an essential role of transcriptional regulation in Rho GTPases-induced oncogenesis. Herein, we demonstrate that RhoA, Rac1, and Cdc42 promote the expression of cyclooxygenase-2 (COX-2) at the transcriptional level by a mechanism that is dependent on the transcription factor nuclear factor-{kappa}B (NF-{kappa}B), but not Stat3, a transcription factor required for RhoA-induced tumorigenesis. With respect to RhoA, this effect is dependent on ROCK, but not PKN. Treatment of RhoA-, Rac1-, and Cdc42-transformed epithelial cells with Sulindac and NS-398, two well-characterized nonsteroid antiinflammatory drugs (NSAIDs), results in growth inhibition as determined by cell proliferation assays. Accordingly, tumor growth of RhoA-expressing epithelial cells in syngeneic mice is strongly inhibited by NS-398 treatment. The effect of NSAIDs over RhoA-induced ...

The small GTPases of the Ras and Rho families are activated by the key growth factors for mast cell development and survival, SLF and IL-3. While there are many clues that activation of Ras and Rho proteins play critical roles in growth, survival and differentiation, as well as in functions, such as migration and degranulation, limitations in the specificity of experimental tools still obscure their precise functions. There is increasing evidence that differences in subcellular localization of closely related GTPases determines important differences in their function. However, other data also point to differences in sensitivity to activation by GEF and in the effectors they engage ...

S78454 (also called PCI-24781) is an orally bioavailable, hydroxamate-based pan-HDACi currently being tested in clinical trials in the US and EU. Like many other HDACi, this drug induces a reversible thrombocytopenia. This thrombocytopenia, which was associated with a decrease in either GATA1 transcriptional activity or the expression of proteins of the Rho GTPase family (RhoA, Cdc42 or Rac), remains poorly understood. Given that the S78454 plasma level is above 100nM in treated patients, we performed a dose-response analysis (from 10 to 100 nM) of the drug effects on CFU-MK growth and cell proliferation. CFU-MKs were generated by ex vivo culture of CD34-positive cells and their differentiation was dose-dependently decreased after either a 24-hour treatment or a continuous exposure to S78454. This effect was associated with a dose-dependent decrease in MK proliferation. When added at day 8 of the culture, at a time-point when MK have nearly finished their endomitotic process and are entering in ...

The Rho GTPases, which are related to the Ras family of proto-oncogenes, have been found to have important roles in regulating the morphogenic and migratory properties of eukaryotic cells. In addition, these proteins have been shown to regulate aspects of cell signaling, cell growth, cell division and cell survival. The Rho GTPases cycle between inactive GDP-bound and active GTP-bound states. In resting cells, Rho GTPases are sequestered in the cytoplasm by forming an inactive complex with guanine dissociation inhibitors (GDIs), and are, thus, unable to exchange guanine nucleotides. Rho GTPases exchange guanine nucleotides at slow rates in vivo, and these reactions can be catalyzed by two different classes of proteins. Upon cell activation, guanine exchange factors stimulate the exchange of GTP for GDP and thereby activate the Rho GTPases, whereas the GTPase activating proteins turn off the Rho GTPase by stimulating their inherent GTP-hydrolysis activity. The active Rho GTPase associates with ...
