Rho GTPase signaling complexes in cell migration and invasion.

ABSTRACT: Cell migration is dependent on the dynamic formation and disassembly of actin filament-based structures, including lamellipodia, filopodia, invadopodia, and membrane blebs, as well as on cell-cell and cell-extracellular matrix adhesions. These processes all involve Rho family small guanosine triphosphatases (GTPases), which are regulated by the opposing actions of guanine nucleotide exchange factors (GEFs) and GTPase-activating proteins (GAPs). Rho GTPase activity needs to be precisely tuned at distinct cellular locations to enable cells to move in response to different environments and stimuli. In this review, we focus on the ability of RhoGEFs and RhoGAPs to form complexes with diverse binding partners, and describe how this influences their ability to control localized GTPase activity in the context of migration and invasion.

Rho GTPase Activating Protein 24 (ARHGAP24) Silencing Promotes Lung Cancer Cell Migration and Invasion by Activating ?-Catenin Signaling.

Project description:BACKGROUND Rho GTPase activating protein (RhoGAPs) is an important negative regulator of the Rho signaling pathway that is involved in tumorigenesis in liver, colon, and renal cancer. However, the mechanism by which Rho GTPase activating protein 24 (ARHGAP24) regulates cell invasion and migration of lung cancer has not been fully explained. MATERIAL AND METHODS In this study, ARHGAP24 expression in lung cancer tissues and cell lines was measured by immunohistochemical and Western blot analysis. Transwell or wound healing analysis was performed to detect the cell migration and invasion of ARHGAP24 modulated A549 and NCI-H1975 cells with ?-catenin inhibitor XAV-939 (10 µM) treatment, and the expression of MMP9, VEGF, and ?-catenin protein was measured by Western blotting. RESULTS Our results showed that ARHGAP24 expression was downregulated in lung cancer tissues and cell lines. pLVX-Puro-ARHGAP24 transfection in A549 cells significantly inhibited cell invasion and migration, along with increased E-cadherin and decreased MMP9, VEGF, Vimentin, and ?-catenin protein expression. pLKO.1-ARHGAP24-shRNA transfection in NCI-H1975 cells significantly promoted cell invasion and migration, accompanied with decreased E-cadherin and increased MMP9, VEGF, and ?-catenin protein expression. Moreover, NCI-H1975 cells with XAV-939 treatment showed decreased cell invasion and migration when compared with pLKO.1-ARHGAP24-shRNA transfection. ARHGAP24 silencing promoted the transcriptional activity of ?-catenin in NCI-H1975 cells. CONCLUSIONS Our findings indicate that ARHGAP24 silencing promotes lung cancer cell migration and invasion through activating ?-catenin signaling.

Downregulation of the Rho GTPase signaling pathway is involved in the microRNA-138-mediated inhibition of cell migration and invasion in tongue squamous cell carcinoma.

Project description:Tumor metastasis is the dominant cause of death in cancer patients, including patients with oral tongue squamous cell carcinoma (TSCC). Previously, we reported that reduced miR-138 level is correlated with enhanced metastatic potential in TSCC cells. Here, we demonstrate that miR-138 suppresses TSCC cell migration and invasion by regulating 2 key genes in the Rho GTPase signaling pathway: RhoC and ROCK2. Direct targeting of miR-138 to specific sequences located in the 3'-untranslated regions of both RhoC and ROCK2 mRNAs was confirmed using luciferase reporter gene assays. Ectopic transfection of miR-138 reduced the expression of both RhoC and ROCK2 in TSCC cells. These reduced expressions, in consequence, led to the reorganization of the stress fibers and the subsequent cell morphology change to a round bleb-like shape as well as the suppression of cell migration and invasion. In contrast, knockdown of miR-138 in TSCC cells enhanced the expression of RhoC and ROCK2, which resulted in an altered, elongated cell morphology, enhanced cell stress fiber formation and accelerated cell migration and invasion. Taken together, our results suggest that miR-138 plays an important role in TSCC cell migration and invasion by concurrently targeting RhoC and ROCK2, and miR-138 may serve as a novel therapeutic target for TSCC patients at risk of metastatic disease.

Activation of Vav/Rho GTPase signaling by CXCL12 controls membrane-type matrix metalloproteinase-dependent melanoma cell invasion.

Project description:Melanoma cells express the chemokine receptor CXCR4, which confers invasive signals on binding to its ligand CXCL12. We show here that knocking down membrane-type matrix metalloproteinase (MT1-MMP) expression translates into a blockade of invasion across reconstituted basement membranes and type I collagen gels in response to CXCL12, which is the result of lack of MMP-2 activation. Interference with MMP-2 expression further confirms its important role during this invasion. Vav proteins are guanine-nucleotide exchange factors for Rho GTPases that regulate actin dynamics and gene expression. We show that melanoma cells express Vav1 and Vav2, which are activated by CXCL12 involving Jak activity. Blocking Vav expression by RNA interference results in impaired activation of Rac and Rho by CXCL12 and in a remarkable inhibition of CXCL12-promoted invasion. Importantly, up-regulation of MT1-MMP expression by CXCL12, a mechanism contributing to melanoma cell invasion, is blocked by knocking down Vav expression or by inhibiting Jak. Together, these data indicate that activation of Jak/Vav/Rho GTPase pathway by CXCL12 is a key signaling event for MT1-MMP/MMP-2-dependent melanoma cell invasion.

FilGAP, a Rho/Rho-associated protein kinase-regulated GTPase-activating protein for Rac, controls tumor cell migration.

Project description:Tumor cells exhibit two interconvertible modes of cell motility referred to as mesenchymal and amoeboid migration. Mesenchymal mode is characterized by elongated morphology that requires high GTPase Rac activation, whereas amoeboid mode is dependent on actomyosin contractility induced by Rho/Rho-associated protein kinase (ROCK) signaling. While elongated morphology is driven by Rac-induced protrusion at the leading edge, how Rho/ROCK signaling controls amoeboid movement is not well understood. We identified FilGAP, a Rac GTPase-activating protein (GAP), as a mediator of Rho/ROCK-dependent amoeboid movement of carcinoma cells. We show that depletion of endogenous FilGAP in carcinoma cells induced highly elongated mesenchymal morphology. Conversely, forced expression of FilGAP induced a round/amoeboid morphology that requires Rho/ROCK-dependent phosphorylation of FilGAP. Moreover, depletion of FilGAP impaired breast cancer cell invasion through extracellular matrices and reduced tumor cell extravasation in vivo. Thus phosphorylation of FilGAP by ROCK appears to promote amoeboid morphology of carcinoma cells, and FilGAP contributes to tumor invasion.

Swiprosin-1 stimulates cancer invasion and metastasis by increasing the Rho family of GTPase signaling.

Project description:Ectopic expression of Swiprosin-1, an actin-binding protein (also known as EF hand domain containing 2; EFHD2), enhanced motile protrusions associated with actin, such as lamellipodia and membrane ruffles. Swiprosin-1 levels were increased in various human cancer tissues, particularly at highly invasive stages of malignant melanoma. Expression of Swiprosin-1 was correlated with that of epidermal growth factor receptor (EGFR) and induced by EGF. In a mouse metastasis model, Swiprosin-1 overexpression induced pulmonary metastasis whereas its knockdown led to marked inhibition of metastasis of highly invasive melanoma cells. Swiprosin-1 at the lamellipodia and membrane ruffles controlled the direction of cell protrusion and enhanced migration velocity through activating the Rho family of small GTPases, including Rac1, Cdc42 and RhoA. Our collective findings support the potential utility of Swiprosin-1 as a therapeutic target to prevent cancer invasion and metastasis.

Cell cycle-dependent Rho GTPase activity dynamically regulates cancer cell motility and invasion in vivo.

Project description:The mechanism behind the spatiotemporal control of cancer cell dynamics and its possible association with cell proliferation has not been well established. By exploiting the intravital imaging technique, we found that cancer cell motility and invasive properties were closely associated with the cell cycle. In vivo inoculation of human colon cancer cells bearing fluorescence ubiquitination-based cell cycle indicator (Fucci) demonstrated an unexpected phenomenon: S/G2/M cells were more motile and invasive than G1 cells. Microarray analyses showed that Arhgap11a, an uncharacterized Rho GTPase-activating protein (RhoGAP), was expressed in a cell-cycle-dependent fashion. Expression of ARHGAP11A in cancer cells suppressed RhoA-dependent mechanisms, such as stress fiber formation and focal adhesion, which made the cells more prone to migrate. We also demonstrated that RhoA suppression by ARHGAP11A induced augmentation of relative Rac1 activity, leading to an increase in the invasive properties. RNAi-based inhibition of Arhgap11a reduced the invasion and in vivo expansion of cancers. Additionally, analysis of human specimens showed the significant up-regulation of Arhgap11a in colon cancers, which was correlated with clinical invasion status. The present study suggests that ARHGAP11A, a cell cycle-dependent RhoGAP, is a critical regulator of cancer cell mobility and is thus a promising therapeutic target in invasive cancers.

A novel KLF6-Rho GTPase axis regulates hepatocellular carcinoma cell migration and dissemination.

Project description:The presence of invasion into the extra-hepatic portion of the portal vein or the development of distant metastases renders hepatocellular carcinoma (HCC) patients ineligible for the only potential curative options for this malignancy-tumor resection or organ transplantation. Gene expression profiling of murine HCC cell lines identified KLF6 as a potential regulator of HCC cell migration. KLF6 knockdown increases cell migration, consistent with the correlation between decreased KLF6 mRNA levels and the presence of vascular invasion in human HCC. Concordantly, single-copy deletion of Klf6 in a HCC mouse model results in increased tumor formation, increased metastasis to the lungs and decreased survival, indicating that KLF6 suppresses both HCC development and metastasis. By combining gene expression profiling and chromatin immunoprecipitation coupled to deep sequencing, we identified novel transcriptional targets of KLF6 in HCC cells including VAV3, a known activator of the RAC1 small GTPase. Indeed, RAC1 activity is increased in KLF6-knockdown cells in a VAV3-dependent manner, and knockdown of either RAC1 or VAV3 impairs HCC cell migration. Together, our data demonstrate a novel function for KLF6 in constraining HCC dissemination through the regulation of a VAV3-RAC1 signaling axis.

Desmoplakin Harnesses Rho GTPase and p38 Mitogen-Activated Protein Kinase Signaling to Coordinate Cellular Migration.

Project description:Desmoplakin (DP) is an obligate component of desmosomal cell-cell junctions that links the adhesion plaque to the cytoskeletal intermediate filament network. While a central role for DP in maintaining the structure and stability of the desmosome is well established, recent work has indicated that DP's functions may extend beyond cell-cell adhesion. In our study, we show that loss of DP results in a significant increase in cellular migration, as measured by scratch wound assays, Transwell migration assays, and invasion assays. Loss of DP causes dramatic changes in actin cytoskeleton morphology, including enhanced protrusiveness, and an increase in filopodia length and number. Interestingly, these changes are also observed in single cells, indicating that control of actin morphology is a cell-cell adhesion-independent function of DP. An investigation of cellular signaling pathways uncovered aberrant Rac and p38 mitogen-activated protein kinase (MAPK) activity in DP knockdown cells, restoration of which is sufficient to rescue DP-dependent changes in both cell migration and actin cytoskeleton morphology. Taken together, these data highlight a previously uncharacterized role for the desmosomal cytolinker DP in coordinating cellular migration via p38 MAPK and Rac signaling.
