AIMS Fascin-1, ezrin and paxillin, cytoskeleton-associated proteins, have been implicated in several human cancers, but their role in laryngeal squamous cell carcinoma (LSCC) is unknown. We investigated the association of their expression and clinicopathologic factors and their prognostic value in LSCC. MATERIALS AND METHODS Quantitative RT-PCR and western blot analyses were used to examine m...
P-glycoprotein is a 170-kd glycosylated transmembrane protein, expressed in a variety of human cells and belonging to the adenosine triphosphate-binding cassette transporter family, whose membrane expression is functionally associated with the multidrug resistance phenotype. However, the mechanisms underlying the regulation of P-glycoprotein functions remain unclear. On the basis of some eviden...
Ezrin, encoded by VIL2, is a membrane-cytoskeletal linker protein that has been suggested to be involved in tumorigenesis. Ezrin expression in esophageal squamous cell carcinoma (ESCC) was described recently, but its clinical significance and the molecular mechanism underlying its regulated expression remain unclear. Thus, we retrospectively evaluated ezrin expression by immunohistochemistry in...
B cell chemotaxis occurs in response to specific chemokine gradients and is critical for homeostasis and immune response. The molecular regulation of B cell membrane–actin interactions during migration is poorly understood. In this study, we report a role for ezrin, a member of the membrane-cytoskeleton cross-linking ezrin-radixin-moesin proteins, in the regulation of the earliest steps of B ce...
Addition of EGF to human carcinoma A-431 cells is known to induce membrane ruffling after approximately 2 min (Chinkers, M., J. A. McKanna, and S. Cohen. 1979. J. Cell Biol. 83:260-265) and the phosphorylation of a protein referred to as p81, a known substrate for various protein-tyrosine kinases (Cooper, J. A., D. F. Bowen-Pope, E. Raines, R. Ross, and T. Hunter. 1982. Cell. 31:263-273). Ezrin...
Accumulating evidence in humans demonstrates that visuo-spatial deficits are the most consistently reported cognitive abnormalities in Parkinson's disease (PD). Ezrin, radixin, and moesin are collectively known as ERM proteins. Although ERM proteins have important implications in cell-shape determination and relevant signaling pathway, they have not been studied in the hippocampus in associatio...
We recently reported that ERM (ezrin, radixin, moesin) proteins are involved in intracellular sorting of Shiga toxin (Stx) and its receptor globotriaosylceramide (Gb3), and that depletion of ezrin and moesin reduced retrograde Golgi transport of Stx. In the same study, we found that knockdown of Vps11, a core subunit of both the homotypic fusion and protein sorting (HOPS) complex and the class ...
Transendothelial cell macroaperture (TEM) tunnels control endothelium barrier function and are triggered by several toxins from pathogenic bacteria that provoke vascular leakage. Cellular dewetting theory predicted that a line tension of uncharacterized origin works at TEM boundaries to limit their widening. Here, by conducting high-resolution microscopy approaches we unveil the presence of an ...
