Rho GTPase function in tumorigenesis
Biochimica et Biophysica Acta (BBA) - Reviews on Cancer, 2009Malignant tumor cells display uncontrolled proliferation, loss of epithelial cell polarity, altered interactions with neighboring cells and the surrounding extracellular matrix, and enhanced migratory properties. Proteins of the Rho GTPase family regulate all these processes in cell culture and, for that reason, Rho GTPases, their regulators, and their

Rho GTPases in hepatocellular carcinoma
Biochimica et Biophysica Acta (BBA) - Reviews on Cancer, 2009Rho GTPases are major regulators of signal transduction pathways and play key roles in processes including actin dynamics, cell cycle progression, cell survival and gene expression, whose deregulation may lead to tumorigenesis. A growing number of in vitro and in vivo studies using tumor-derived cell lines, primary tumors and animal cancer models ...

Rho GTPases are molecular switches that control a wide variety of signal transduction pathways in all eukaryotic cells. They are known principally for their pivotal role in regulating the actin cytoskeleton, but their ability to influence cell polarity, microtubule dynamics, membrane transport pathways and transcription factor activity is probably just

Current Protocols in Cell Biology, 2008
AbstractThe Rho GTPase family of signaling proteins controls a wide range of highly dynamic cellular processes. Activation of Rho GTPases can be investigated and quantified in cell extracts using so‐called pull‐down assays. Proteins that bind specifically to the activated form of the Rho GTPase are used to capture it onto a bead support.

Trends in Genetics, 1994
Ras-related GTP-binding proteins (GTPases) of the rho subfamily play important roles in regulating the organization of the actin cytoskeleton. A large number of multifunctional proteins that can stimulate their intrinsic GTPase activity have been identified.

It is becoming increasingly clear that the complex family of Rho-related GTPases and their associated regulators and targets are essential mediators of a variety of morphogenetic events required for normal development of multicellular organisms. It is worth noting that the results obtained thus far indicate that the Rho family proteins are largely ...

The Immunological Synapse and Rho GTPases
2005Rho GTPases are molecular switches controlling a broad range of cellular processes including lymphocyte activation. Not surprisingly, Rho GTPases are now recognized as pivotal regulators of antigen-specific T cell activation by APCs and immunological synapse formation.

Plant GTPases: the Rhos in bloom
Trends in Cell Biology, 2000In animal cells and in fungi, small GTP-binding proteins of the Rho family have well-established roles in morphogenesis, cell-cycle progression, gene transcription and the generation of superoxide anions. The presence of these proteins in plant cells, however, has been established only recently, and the role of Rho GTPases in plants is now coming into ...

Rho GTPases in Hematopoietic Cells
Antioxidants & Redox Signaling, 2005The ubiquitous Rho GTPases are instrumental in the organization of the actin cytoskeleton, but also for the control of gene expression. Here we review the role of the major members of this family, i.e., RhoA, Rac1, Rac2, and Cdc42, and their intracellular signaling in hematopoietic cells.

RHO GTPASES in neuronal morphogenesis
Nature Reviews Neuroscience, 2000The Rho family of small GTPases act as intracellular molecular switches that transduce signals from extracellular stimuli to the actin cytoskeleton and the nucleus. Recent evidence implicates Rho GTPases in the regulation of neuronal morphogenesis, including migration, polarity, axon growth and guidance, dendrite elaboration and plasticity, and synapse
