Rac1 Signaling: From Intestinal Homeostasis to Colorectal Cancer Metastasis
Cancers, 2020 The small GTPase Rac1 has been implicated in a variety of dynamic cell biological processes, including cell proliferation, cell survival, cell-cell contacts, epithelial mesenchymal transition (EMT), cell motility, and invasiveness.

Unconventional role of RAC1 in MET-driven anchorage-independent tumor growth
Molecular & Cellular Oncology, 2020 We reported that RAC1 is a master regulator of cell migration and anchorage-independent growth, downstream of the oncogenic Receptor Tyrosine Kinase (RTK) MET.

Tyrosine phosphorylation of Rac1: a role in regulation of cell spreading. [PDF]
PLoS ONE, 2011 Rac1 influences a multiplicity of vital cellular- and tissue-level control functions, making it an important candidate for targeted therapeutics. The activity of the Rho family member Cdc42 has been shown to be modulated by tyrosine phosphorylation at ...

A role for the small GTPases RAC1 and RAC1b in the modulation of NIS expression: potentiation of therapy with radioactive iodine in differentiated thyroid carcinoma [PDF]
, 2019 Introduction or Background: The Sodium Iodide Symporter (NIS) is responsible for active transport of iodide into thyroid follicular cells. The retention of its functional expression in most of the well-differentiated thyroid carcinomas (DTCs) enables ...

Nucleophosmin1 is a negative regulator of the small GTPase Rac1. [PDF]
PLoS ONE, 2013 The Rac1 GTPase is a critical regulator of cytoskeletal dynamics and controls many biological processes, such as cell migration, cell-cell contacts, cellular growth and cell division.

Rac1 drives intestinal stem cell proliferation and regeneration [PDF]
, 2013 Adult stem cells are responsible for maintaining the balance between cell proliferation and differentiation within self-renewing tissues. The molecular and cellular mechanisms mediating such balance are poorly understood.

Clinical Therapeutics, 2015 RAC1 is a GTPase member of the RAS superfamily, and RAC1(P29S) was recently identified as the third most common recurrent mutation in melanomas, affecting 4-7% of the patients. This is an oncogenic mutation, because the mutant protein remains mostly in its active GTP-bound form, and its ectopic expression increases the rate of normal melanocytes ...

IAPs as E3 ligases of Rac1 : shaping the move [PDF]
, 2012 Inhibitors of Apoptosis Proteins (IAPs) are well-studied E3 ubiquitin ligases predominantly known for regulation of apoptosis. We uncovered that IAPs can function as a direct E3 ubiquitin ligase of RhoGTPase Rac1.

Rac1 function during fucoid development [PDF]
Plant Signaling & Behavior, 2008 Morphogenesis in fucoid algae begins with adhesive secretion and rhizoid germination, developmental events that secure the alga within the intertidal zone. The importance of the actin cytoskeleton during these processes has been well established; but in general, little is known about actin regulation within the stramenopile lineage.

Chronic inflammation evoked by pathogenic stimulus during carcinogenesis
4 open, 2019 A pathogenic (biological or chemical) stimulus is the earliest information received by a cell that can result in the disruption of homeostasis with consequent development of disease.
