Control of T lymphocyte morphology by the GTPase Rho

open access: yesBMC Cell Biology, 2003
Background Rho family GTPase regulation of the actin cytoskeleton governs a variety of cell responses. In this report, we have analyzed the role of the GTPase Rho in maintenance of the T lymphocyte actin cytoskeleton.

Rho GTPases in embryonic development [PDF]

open access: yesSmall GTPases, 2014
In the last decade, several mouse models for RhoA, Rac1, and Cdc42 have emerged and have contributed a great deal to understanding the precise functions of Rho GTPases at early stages of development. This review summarizes our current knowledge of various mouse models of tissue-specific ablation of Cdc42, Rac1, and RhoA with emphasis on early ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Dynamic Mechanical Loading Modulates Extracellular Vesicle Production and Cargo in Meniscus Fibrochondrocytes

open access: yesAdvanced Materials Interfaces, EarlyView.
Dynamic mechanical loading of outer meniscus fibrochondrocytes increases extracellular vesicle (EV) yield and alters EV composition. When applied to progenitor cells, these mechanically primed EVs modulate the expression of matrix‐related genes.

Rho GTPases in ameloblast differentiation

open access: yesJapanese Dental Science Review, 2016
During tooth development, ameloblasts differentiate from inner enamel epithelial cells to enamel-forming cells by modulating the signal pathways mediating epithelial-mesenchymal interaction and a cell-autonomous gene network. The differentiation process of epithelial cells is characterized by marked changes in their morphology and polarity, accompanied

Rho GTPases and signaling networks [PDF]

open access: yesGenes & Development, 1997
The Rho GTPases form a subgroup of the Ras superfamily of 20- to 30-kD GTP-binding proteins that have been shown to regulate a wide spectrum of cellular functions. These proteins are ubiquitously expressed across the species, from yeast to man. The mammalian Rho-like GTPases comprise at least 10 distinct proteins: RhoA, B, C, D, and E; Rac1 and 2; RacE;

Cyclic Mechanical Loading of Cardiomyocytes via Pressure‐Driven Non‐Planar Membrane Deformation in a Bioreactor System

open access: yesAdvanced Science, EarlyView.
In this research article, Mansoor and coworkers present a novel device that applies controlled mechanical stimuli to cardiomyocytes using pressure‐driven membrane deformation. By exposing cells to physiologically and pathologically relevant loading conditions, the platform reproduces distinct structural, functional and molecular responses associated ...

Control of Local Rho GTPase Crosstalk by Abr [PDF]

open access: yes, 2011
SummaryBackgroundThe Rho GTPases—Rho, Rac, and Cdc42—regulate the dynamics of F-actin (filamentous actin) and myosin-2 with considerable subcellular precision.

Molecular perturbation strategies to examine spatiotemporal features of Rho GEF and Rho GTPase activity in living cells [PDF]

open access: yes, 2019
Much of our current knowledge of Rho GTPase networks and the regulation by Rho guanine exchange factors (Rho GEFs) and Rho GTPase activating proteins (Rho GAPs) is based on population-based techniques.
