Rgnef activation corresponds with RhoA GTP binding upon FN stimulation.

open access: yes, 2012
(A) Evaluation of Rgnef activation in lysates of normal MEFs held in suspension for 30 min and then replated onto 10 µg/ml FN for the indicated times. Pull-down assays using GST-RhoA (G17A) and Rgnef immunoblotting reveals binding at 60 to 120 min after ...

MiR‐375 in CAFs‐Derived EVs Promotes HCC Progression via Regulating RASA1 and May Potentially Serve as a Biomarker for HCC

open access: yesCancer Science, Volume 117, Issue 8, Page 2208-2220, August 2026.
CAFs could transfer EVs miR‐375 into endothelial cells with a low level of RASA1 and further promote EC angiogenesis. Plasma EVs miR‐375 have the potential values as a novel diagnostic and prognostic biomarker for HCC. ABSTRACT Cancer‐associated fibroblasts (CAFs) in the tumor microenvironment play an important role in cancer initiation and progression

Folding transitions during assembly of the eukaryotic mRNA cap-binding complex. [PDF]

open access: yes, 2006
The cap-binding protein eIF4E is the first in a chain of translation initiation factors that recruit 40S ribosomal subunits to the 5' end of eukaryotic mRNA. During cap-dependent translation, this protein binds to the 5'-terminal m(7)Gppp cap of the mRNA,

Mechanisms and Research Progress of Leech in Diabetic Ulcer Fibrosis

open access: yesInternational Wound Journal, Volume 23, Issue 8, August 2026.
ABSTRACT Delayed wound healing is a major complication of diabetes, with its core pathological process being pathological fibrosis driven by persistent inflammation, metabolic disorders and vascular dysfunction under hyperglycemia. This process involves pathological retention of inflammatory cells, abnormal expression of pro‐fibrotic factors, and ...

Analysis of Rho GTPase signalling pathways regulating epithelial morphogenesis [PDF]

open access: yes, 2010
Rho GTPases are molecular switches controlling many aspects of cell behaviour, including cell cycle progression, cell division, migration and morphology. The activity of Rho proteins is regulated by conformational changes induced by binding of guanine

Microtubules in Spinal Cord Injury: From Cytoskeletal Dysregulation to Therapeutic Regeneration

open access: yesJournal of Neurochemistry, Volume 170, Issue 8, August 2026.
Graphical illustration of the microtubule interactome following spinal cord injury as potential targets for therapy. ABSTRACT Spinal cord injury (SCI) triggers an immediate and sustained disruption of the composition and organization of the neuronal cytoskeleton.

eNOS Uncoupling, Shear‐Stress Tolerance, and the Two‐Threshold Model of Post‐Exertional Malaise in Long COVID: A Mechanistic Hypothesis With Implications for Physiotherapy and Recovery Protocols

open access: yesMicrocirculation, Volume 33, Issue 6, August 2026.
ABSTRACT Objective To propose and make testable a mechanistic hypothesis for post‐exertional malaise (PEM) in a clinically distinct subset of Long COVID patients, in whom delayed exertional symptoms coexist with consistently normal macrovascular investigations.

An HflX-type GTPase from Sulfolobus solfataricus binds to the 50S ribosomal subunit in all nucleotide-bound states [PDF]

open access: yes, 2011
HflX GTPases are found in all three domains of life, Bacteria, Archaea, and Eukaryotes. HflX from Escherichia coli has been shown to bind to the 50S ribosomal subunit in a nucleotide-dependent manner and this interaction strongly stimulates its GTPase ...

Unraveling the Molecular Mechanisms Underlying Spontaneous Multipolar Mitosis Through CIN‐seq

open access: yesAdvanced Science, Volume 13, Issue 40, 17 July 2026.
Multipolar mitosis, a hallmark of chromosomal instability (CIN), drives tumor heterogeneity but is challenging to study in live cells. Using CIN‐seq, a single‐cell multiomics method, we profiled rare CIN events and identified mechanisms associated with viable multipolar mitosis, including PTEN attenuation, Rho GTPase‐driven cytokinesis failure, and ...

Structure and function of bacterial dynamin-like proteins [PDF]

open access: yes, 2012
Membrane dynamics are essential for numerous cellular processes in eukaryotic and prokaryotic cells. In eukaryotic cells, membrane fusion and fission are often catalyzed by large GTPases of the dynamin protein family. These proteins couple GTP hydrolysis
