ADP-ribosylation of the GTP-binding protein RhoA blocks cytoplasmic division in human myelomonocytic cells [PDF]

open access: yesBiochemical Journal, 1995
To test the role of Rho GTP-binding proteins in growth regulation of human myelomonocytic tumour cells we used recombinant C3 exoenzyme of Clostridium botulinum to specifically ADP-ribosylate and inactivate Rho proteins in situ. In homogenates of HL60 cells, the C3 exoenzyme [32P]ADP-ribosylated one protein that was identified as RhoA by immunoblot and

The GTP-binding Protein RhoA Mediates Na,K-ATPase Exocytosis in Alveolar Epithelial Cells [PDF]

open access: yesMolecular Biology of the Cell, 2003
The purpose of this study was to define the role of the Rho family of small GTPases in the β-adrenergic regulation of the Na,K-ATPase in alveolar epithelial cells (AEC). The β-adrenergic receptor agonist isoproterenol (ISO) increased the Na,K-ATPase protein abundance at the plasma membrane and activated RhoA in a time-dependent manner.

The Cytotoxin YopT of Yersinia enterocoliticaInduces Modification and Cellular Redistribution of the Small GTP-binding Protein RhoA [PDF]

open access: yesJournal of Biological Chemistry, 1999
Pathogenic Yersinia enterocolitica produces two virulence plasmid-encoded cytotoxins, YopE and YopT, that are translocated into target cells where they disrupt the actin cytoskeleton. Here we show that infection of cells with wild type Y. enterocolitica and a yopE mutant, but not with a yopT mutant, induces an increase in the electrophoretic mobility ...

Automated NMR fragment based screening identified a novel interface blocker to the LARG/RhoA complex. [PDF]

open access: yesPLoS ONE, 2014
The small GTPase cycles between the inactive GDP form and the activated GTP form, catalyzed by the upstream guanine exchange factors. The modulation of such process by small molecules has been proven to be a fruitful route for therapeutic intervention to

RHGF-2 is an essential Rho-1 specific RhoGEF that binds to the multi-PDZ domain scaffold protein MPZ-1 in Caenorhabditis elegans. [PDF]

open access: yesPLoS ONE, 2012
RhoGEF proteins activate the Rho family of small GTPases and thus play a key role in regulating fundamental cellular processes such as cell morphology and polarity, cell cycle progression and gene transcription.

Vav Proteins in Development of the Brain: A Potential Relationship to the Pathogenesis of Congenital Zika Syndrome?

open access: yesViruses, 2022
Zika virus (ZIKV) infection during pregnancy can result in a significant impact on the brain and eye of the developing fetus, termed congenital zika syndrome (CZS).

Septin11 promotes hepatocellular carcinoma cell motility by activating RhoA to regulate cytoskeleton and cell adhesion

open access: yesCell Death and Disease, 2023
Septins as GTPases in the cytoskeleton, are linked to a broad spectrum of cellular functions, including cell migration and the progression of hepatocellular carcinoma (HCC).

The RhoA transcriptional program in pre-T cells [PDF]

open access: yes, 2007
The GTPase RhoA is essential for the development of pre-T cells in the thymus. To investigate the mechanisms used by RhoA to control thymocyte development we have used Affymetrix gene profiling to identify RhoA regulated genes in T cell progenitors.

Dimethyloxalylglycine Promotes Bone Marrow Mesenchymal Stem Cell Osteogenesis via Rho/ROCK Signaling

open access: yesCellular Physiology and Biochemistry, 2016
Background/Aims: We investigated the role of dimethyloxalylglycine (DMOG) in bone marrow mesenchymal stem cell (BMSC) osteogenesis mediated by RhoA/ROCK. Methods: BMSCs were cultured with and without DMOG and/or Y-27632 (ROCK1 inhibitor).
