Activation of RhoA and SAPK/JNK signalling pathways by the RhoA-specific exchange factor mNET1 [PDF]
We have characterized the DH domain protein mNET1, a Rho-family guanine nucleotide exchange factor (GEF). N-terminal truncation of mNET1 generates an activated transforming form of the protein, mNET1DeltaN, which acts as a GEF for RhoA but not Cdc42 or Rac1.

RhoA in aneurysmal subarachnoid hemorrhage
Aneurysmal subarachnoid haemorrhage (aSAH) is a severe subtype of stroke, mediated by the spontaneous rupture of an intracranial aneurysm, that frequently occurs in people between 40 and 60 years of age. Cerebral vasospasm (CV), and related delayed cerebral ischemia (DCI), is a clinical syndrome of the focal neurologic deficits that develop typically ...

Thrombin-induced Rapid Geranylgeranylation of RhoA as an Essential Process for RhoA Activation in Endothelial Cells [PDF]
RhoA plays a critical signaling role in thrombin-induced endothelial dysfunction. The possible thrombin regulation of geranylgeranylation, a lipid modification, of unprocessed RhoA and the significance of the geranylgeranylation in RhoA activation in endothelial cells (ECs) are not well understood.

Survival of the resilient: Mechano-adaptation of circulating tumor cells to fluid shear stress
During metastasis, cancer cells traverse the circulation to reach distant organs. Conventionally, this journey has been regarded as mechanically destructive to circulating tumor cells from solid tissues.

p66Shc mediates anoikis through RhoA [PDF]
Detachment of parenchymal cells from a solid matrix switches contextual cues from survival to death during anoikis. Marked shape changes accompany detachment and are thought to trigger cell death, although a working model to explain the coordination of attachment sensation, shape change, and cell fate is elusive.

RhoA-ROCK and p38MAPK-MSK1 mediate vitamin D effects on gene expression, phenotype, and Wnt pathway in colon cancer cells [PDF]
The active vitamin D metabolite 1,25-dihydroxy-vitamin D-3 (1,25(OH)(2)D-3) inhibits proliferation and promotes differentiation of colon cancer cells through the activation of vitamin D receptor (VDR), a transcription factor of the nuclear receptor ...

A transcriptional cross–talk between RhoA and c–Myc inhibits the RhoA/Rock–dependent cytoskeleton [PDF]
The GTPase RhoA participates in a number of cellular processes, including cytoskeletal organization, mitogenesis and tumorigenesis. We have previously shown that the transforming activity of an oncogenic version of RhoA (Q63L mutant) was highly dependent on the transcriptional factor c-Myc.

Arp2/3-Branched Actin Maintains an Active Pool of GTP-RhoA and Controls RhoA Abundance
Small GTPases regulate cytoskeletal dynamics, cell motility, and division under precise spatiotemporal control. Different small GTPases exhibit cross talks to exert feedback response or to act in concert during signal transduction.

RhoA promotes osteoclastogenesis and regulates bone remodeling through mTOR-NFATc1 signaling
Background The cytoskeletal architecture of osteoclasts (OCs) and bone resorption activity must be appropriately controlled for proper bone remodeling, which is associated with osteoporosis.
