Proapoptotic and antiinvasive activity of Rac1 small molecule inhibitors on malignant glioma cells [PDF]

open access: yes, 2014
Malignant gliomas are characterized by an intrinsic ability to invade diffusely throughout the normal brain tissue. This feature contributes mainly to the failure of existing therapies. Deregulation of small GTPases signaling, in particular Rac1 activity,

Multisite phosphorylation of the guanine nucleotide exchange factor Cdc24 during yeast cell polarization. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:Cell polarization is essential for processes such as cell migration and asymmetric cell division. A common regulator of cell polarization in most eukaryotic cells is the conserved Rho GTPase, Cdc42.

Dietary Methionine Restriction Regulates Liver Protein Synthesis and Gene Expression Independently of Eukaryotic Initiation Factor 2 Phosphorylation in Mice [PDF]

open access: yes, 2017
Background: The phosphorylation of eukaryotic initiation factor 2 (p-eIF2) during dietary amino acid insufficiency reduces protein synthesis and alters gene expression via the integrated stress response (ISR).Objective: We explored whether a Met ...

Small GTP-binding protein Rho-mediated signaling promotes proliferation of rheumatoid synovial fibroblasts [PDF]

open access: yes, 2005
Rho is a major small GTP-binding protein that is involved in the regulation of various cell functions, including proliferation and cell migration, through activation of multiple signaling molecules in various types of cells.

ARHGEF37 overexpression promotes extravasation and metastasis of hepatocellular carcinoma via directly activating Cdc42

open access: yesJournal of Experimental & Clinical Cancer Research, 2022
Background The extravasation capability of hepatocellular carcinoma (HCC) cells plays a vital role in distant metastasis. However, the underlying mechanism of extravasation in HCC lung metastasis remains largely unclear.

Ric-8A, a Gα protein guanine nucleotide exchange factor potentiates taste receptor signaling

open access: yesFrontiers in Cellular Neuroscience, 2009
Taste receptors for sweet, bitter and umami tastants are G-protein coupled receptors (GPCRs). While much effort has been devoted to understanding G-protein-receptor interactions and identifying the components of the signalling cascade downstream of these

Research progress in the relationship between PREX1 gene and tumor pathogenesis [PDF]

open access: yesXin yixue, 2023
Phosphatidylinositol-3, 4, 5-triphosphate-dependent Rac exchange factor 1 (PREX1) is a coding gene that is abnormally expressed in a variety of tumors. As a guanine nucleotide exchange factor (RacGEF) of small GTP binding protein Rac1, PREX1 gene-encoded

An Activating Mutation in sos-1 Identifies Its Dbl Domain as a Critical Inhibitor of the Epidermal Growth Factor Receptor Pathway during Caenorhabditis elegans Vulval Development [PDF]

open access: yes, 2007
Proper regulation of receptor tyrosine kinase (RTK)-Ras-mitogen-activated protein kinase (MAPK) signaling pathways is critical for normal development and the prevention of cancer.

Membrane and Protein Interactions of the Pleckstrin Homology Domain Superfamily. [PDF]

open access: yes, 2015
The human genome encodes about 285 proteins that contain at least one annotated pleckstrin homology (PH) domain. As the first phosphoinositide binding module domain to be discovered, the PH domain recruits diverse protein architectures to cellular ...
