Protein kinase Ciota (PKCiota) drives transformed growth of non-small cell lung cancer (NSCLC) cells through the Rho family GTPase Rac1. We show here that PKCiota activates Rac1 in NSCLC cells by formation of a PKCiota-Par6alpha complex that drives anchorage-independent growth and invasion through a …

Racs Are Involved In The Regulation Of Important Cellular Processes Including Mitogenesis. We Found That The E3 Ubiquitination Ligase Subunit Cullin-1 Interacts With Constitutively Active Rac3 But Not With Wild-type Rac3 In Yeast. In Mammalian Cell

This gene encodes a protein containing an N-terminus RING-finger, four SH3 domains, and a region implicated in binding of the Rho GTPase Rac. Via the RING-finger, the encoded protein has been shown to function as an ubiquitin-protein ligase involved in protein sorting at the trans-Golgi network. The encoded protein may also act as a scaffold for the c-Jun N-terminal kinase signaling pathway, facilitating the formation of a functional signaling module.

Glioblastoma (GBM) invasion and migration are key biological behaviors leading to refractoriness to current therapies and infiltration into the non‑tumor brain parenchyma. GBM cell migration is strongly dependent on tumor architecture in vivo, which is absent in traditional two‑dimensional (2D) monolayer culture. The present study applied a three‑dimensional (3D) hydrogel model to rebuild the tumor architecture in vitro. Treatment with NSC23766, a specific inhibitor of Ras‑related C3 botulinum toxin substrate 1 (Rac1), inhibited the mesenchymal invasiveness however triggered the amoeboid motility called mesenchymal‑amoeboid transition (MAT). Notably, NSC23766 stimulated U87 GBM cell migration in the 3D hydrogel. However, this compound inhibited cell motility in 2D monolayer culture without tumor architecture for MAT, suggesting the advantage of 3D hydrogel to investigate tumor cell invasion. Due to the inverse interaction of Rac1 and Ras homolog family member A (RhoA) signaling in the ...

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 GTPases regulate the morphology of cells stimulated by extracellular ligands. Their activation is controlled by guanine exchange factors (GEF) that catalyze their binding to GTP. The multidomain Trio protein represents an emerging class of Ρ regulators that contain two GEF domains of distinct specificities. We report here the characterization of Rho signaling pathways activated by the N-terminal GEF domain of Trio (TrioD1). In fibroblasts, TrioD1 triggers the formation of particular cell structures, similar to those elicited by RhoG, a GTPase known to activate both Rac1 and Cdc42Hs. In addition, the activity of TrioD1 requires the microtubule network and relocalizes RhoG at the active sites of the plasma membrane. Using a classical in vitro exchange assay, TrioD1 displays a higher GEF activity on RhoG than on Rac1. In fibroblasts, expression of dominant negative RhoG mutants totally abolished TrioD1 signaling, whereas dominant negative Rac1 and Cdc42Hs only led to partial and complementary ...

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 ...

We have examined the involvement of components of the interleukin-1 (IL-1) signaling pathway in the transactivation of gene expression by the p65 subunit of NF-kappaB. Transient transfection of cells with plasmids encoding wild-type MyD88, IL-1 receptor-associated kinase 1 (IRAK-1), and TRAF-6 drove p65-mediated transactivation. In addition, dominant negative forms of MyD88, IRAK-1, and TRAF-6 inhibited the IL-1-induced response. In cells lacking MyD88 or IRAK-1, no effect of IL-1 was observed. Together, these results indicate that MyD88, IRAK-1, and TRAF-6 are important downstream regulators of IL-1-mediated p65 transactivation. We have previously shown that the low-molecular-weight G protein Rac1 is involved in this response. Constitutively active RacV12-mediated transactivation was not inhibited by dominant negative MyD88, while dominant negative RacN17 inhibited the MyD88-driven response, placing Rac1 downstream of MyD88 on this pathway. Dominant negative RacN17 inhibited wild-type IRAK-1- ...

Our central finding is that a relatively small change in total Rac1 activity can serve as a switch that regulates the overall intrinsic pattern of cell migration of a cell. By using at least three different approaches (mutagenesis, RNA interference, and manipulation of the extracellular environment between 2D and 3D), we demonstrate that moderate levels of active Rac support random motility by selectively promoting peripheral lamellae that permit cell turning, but reductions of active Rac by ≥30% instead support directionally persistent migration using axial lamellae.. This role of Rac in regulating the capacity for random versus directionally persistent motility was found for a variety of cell types, including fibroblasts and epithelial cells, suggesting that it is a common phenomenon. Moderate changes in Rac activity did not necessarily affect the velocity of cell migration, and in a 3D environment, suppression of Rac activity occurred together with increased velocity, indicating the ...

Members of the Rho family of GTP‐binding proteins function as molecular switches in biological response pathways that result in changes in the actin cytoskeletal architecture, the stimulation of cell cycle progression and gene transcription, and the regulation of intracellular trafficking activities (Van Aelst and DSouza‐Schorey, 1997; Hall, 1998; Bar‐Sagi and Hall, 2000; Erickson and Cerione, 2001). Three classes of proteins, GTPase‐activating proteins (GAPs), guanine nucleotide dissociation inhibitors (GDIs), and guanine nucleotide exchange factors (GEFs), regulate the cycling of these GTP‐binding proteins between their GDP‐bound and GTP‐bound states (Boguski and McCormick, 1993). Rho family proteins, such as Cdc42 and Rac, are activated by a number of upstream stimuli, as mediated by members of the Dbl (diffuse B‐cell lymphoma) family of GEFs (Whitehead et al, 1997; Hoffman and Cerione, 2002). One subgroup of the Dbl family, the Cool/Pix proteins (Cool for cloned‐out of ...

The inhibitor is bound to RAC2 protein (Ras-related C3 botulinum toxin substrate 2). RAC2 has S-geranylgeranyl cysteine 189. The geranylgeranyl residue can be buried in the membrane if the C-terminus of RAC2 is extended or unfolded (the C-terminal residues are missing in the crystal structure). The interaction with membrane is weak, since this is the inactive (GDP-bound) state. RAC2 is membrane-associated when activated ...

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 ...

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. ...

Rho family GTPases, members of the Ras superfamily of G proteins, govern multiple cellular processes, including proliferation, transformation, cell motility, and apoptosis. Numerous studies reveal that the Rho GTPases Rac and Cdc42 can either promote or inhibit apoptosis, depending on the cell type and apoptotic stimulus examined. For example, in fibroblasts and some hematopoietic cells, constitutively active Rac protects cells from apoptosis induced by Ras or factor withdrawal (1, 2, 3) . In contrast, activated Rac and Cdc42 can induce apoptosis in Jurkat T lymphocytes, thymocytes, peripheral T cells, and neuronal cell lines (4, 5, 6, 7, 8, 9, 10) . Most forms of apoptosis require the activation of a family of proteases termed caspases (11) . A growing number of cellular proteins have been identified as caspase substrates, and in some cases, cleavage has been shown to modulate their biochemical activity, contributing to various aspects of the apoptotic program. For example, two caspase ...

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 ...
