Gradients of Rac1 Nanoclusters Support Spatial Patterns of Rac1 Signaling [PDF]
Summary: Rac1 is a small RhoGTPase switch that orchestrates actin branching in space and time and protrusion/retraction cycles of the lamellipodia at the cell front during mesenchymal migration.

Endothelial RhoGEF Trio is involved in angiogenesis [PDF]
Endothelial cells lining the vessel wall are instrumental in angiogenesis. They initiate this process and remodel their actin cytoskeleton to facilitate proliferation and migration from pre-existing vessels.

Rac1 S71 Mediates the Interaction between Rac1 and 14-3-3 Proteins [PDF]
Both 14-3-3 proteins (14-3-3s) and Rho proteins regulate cytoskeleton remodeling and cell migration, which suggests a possible interaction between the signaling pathways regulated by these two groups of proteins.

Coxiella burnetii Phagocytosis Is Regulated by GTPases of the Rho Family and the RhoA Effectors mDia1 and ROCK [PDF]
The GTPases belonging to the Rho family control the actin cytoskeleton rearrangements needed for particle internalization during phagocytosis. ROCK and mDia1 are downstream effectors of RhoA, a GTPase involved in that process.

Roads to Stat3 Paved with Cadherins
The engagement of cadherins, cell-to-cell adhesion proteins, triggers a dramatic increase in the levels and activity of the Rac/Cdc42 GTPases, through the inhibition of proteasomal degradation.

Since its description more than two decades ago as a substrate for botulinum C3 exoenzyme ([Didsbury et al , 1989][1]), Rac1 has been one of the most studied small GTPases of the Ras superfamily. Interest in Rac1 exploded in 1992 when Ridley and Hall published their seminal work showing that Rac1 regulates the actin cytoskeleton to promote lamellipodia

Presynaptic Rac1 controls synaptic strength through the regulation of synaptic vesicle priming
Synapses contain a limited number of synaptic vesicles (SVs) that are released in response to action potentials (APs). Therefore, sustaining synaptic transmission over a wide range of AP firing rates and timescales depends on SV release and replenishment.

Short-hairpin RNA-mediated suppression of cortactin may inhibit the migration and invasion abilities of endometrial cancer cells by reducing lamellipodia [PDF]
Objective(s): The prognosis of endometrial cancer (EC) is significantly affected by tumor infiltration and metastasis. Cortactin (CTTN) regulates infiltration and metastasis in other tumors. Studies on the role and mechanism of CTTN in EC are limited and

Signaling by the Rho GTPase Rac1 is key to the regulation of cytoskeletal dynamics, cell spreading and adhesion. It is widely accepted that the inactive form of Rac1 is bound by Rho GDI, which prevents Rac1 activation and Rac1-effector interactions.

Melittin Prevents Metastasis of Epidermal Growth Factor-Induced MDA-MB-231 Cells through The Inhibition of The SDF-1α/CXCR4 Signaling Pathway [PDF]
Objective: Melittin is one of the natural components of bee venom (Apis mellifera), and its anticancer and antimetastatic properties have been well established, but the underlying mechanism remains elusive.
