Vav family exchange factors: Potential regulator in atherosclerosis
Biochemistry and Biophysics ReportsThe Vav family of guanosine nucleotide exchange factors (GEFs) regulates the phosphorylation of tyrosinase, influencing various physiological and pathological processes by modulating the binding of Rho GTPases to GDP/GTP.

Characterization of ROP GTPase-activated Arabidopsis receptor-like cytoplasmic kinases (RLCK class VI_A) [PDF]
, 2011 Plants have to respond and adapt to a variety of continuously changing environmental factors in order to establish an appropriate developmental strategy to ensure survival. There are ample data showing that protein phosphorylation/dephosphorylation plays

Unraveling the Molecular Mechanisms Underlying Spontaneous Multipolar Mitosis Through CIN‐seq
Advanced Science, EarlyView.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 ...

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

Advanced Science, EarlyView.ABSTRACT Liver metastasis is a leading cause of mortality in colorectal cancer (CRC), where the inflammatory tumor microenvironment, specifically neutrophil infiltration, significantly promotes metastatic colonization. This study reveals a pro‐metastatic role for alpha‐1 antitrypsin (A1AT) in CRC liver metastasis via a dual mechanism involving ...

Roles of Rap1 signaling in tumor cell migration and invasion
Cancer Biology & Medicine, 2017 Ras-associated protein-1 (Rap1), a small GTPase in the Ras-related protein family, is an important regulator of basic cellular functions (e.g., formation and control of cell adhesions and junctions), cellular migration, and polarization.

RhoA and Rac1 in Liver Cancer Cells: Induction of Overexpression Using Mechanical Stimulation
Micromachines, 2020 Liver cancer, especially hepatocellular carcinoma (HCC), is an aggressive disease with an extremely high mortality rate. Unfortunately, no promising markers are currently available for the early diagnosis of this disease.

Abr and Bcr are multifunctional regulators of the Rho GTP-binding protein family. [PDF]
Proceedings of the National Academy of Sciences, 1995 Philadelphia chromosome-positive leukemias result from the fusion of the BCR and ABL genes, which generates a functional chimeric molecule. The Abr protein is very similar to Bcr but lacks a structural domain which may influence its biological regulatory capabilities. Both Abr and Bcr have a GTPase-activating protein (GAP) domain similar to those found

Biotechnology and Bioengineering, EarlyView.ABSTRACT In vitro transcription (IVT) plays a critical role in the manufacture of mRNA vaccines and therapeutics. Optimizing mRNA yield and ensuring product quality, such as capping efficiency and integrity, are essential but mechanistically complex. This study presents a modular mechanistic model of the IVT process to advance scientific understanding ...
