Abstract Background Fascin is the main actin cross-linker protein that regulates adhesion dynamics and stabilizes cell protrusion, such as filopodia. In human cancer, fascin expression correlates with aggressive clinical features. This study aimed to determine patterns of fascin-1 assessed its prognostic significance in colorectal cancer. Methods One hundred eleven specimens patients primary re...
Because of the early onset of local invasion and distant metastasis, pancreatic ductal adenocarcinoma (PDAC) is the most lethal human malignant tumor, with a 5-year survival rate of less than 5%. In this study, we investigated the role of fascin, a prometastasis actin-bundling protein, in PDAC progression, invasion, and the molecular mechanisms underlying fascin overexpression in PDAC. Our data...
Fascin is an actin-binding and bundling protein that is highly upregulated in most epithelial cancers. Fascin promotes cell migration and adhesion dynamics in vitro and tumour cell metastasis in vivo. However, potential non-actin bundling roles for fascin remain unknown. Here, we show for the first time that fascin can directly interact with the microtubule cytoskeleton and that this does not d...
BACKGROUND & AIMS Pancreatic ductal adenocarcinoma (PDAC) is often lethal because it is highly invasive and metastasizes rapidly. The actin-bundling protein fascin has been identified as a biomarker of invasive and advanced PDAC and regulates cell migration and invasion in vitro. We investigated fascin expression and its role in PDAC progression in mice. METHODS We used KRas(G12D) p53(R172H) ...
Fascin is an evolutionarily conserved actin-binding protein that plays a key role in forming filopodia. It is widely thought that this function involves fascin directly bundling actin filaments, which is controlled by an N-terminal regulatory serine residue. In this paper, by studying cellular processes in Drosophila melanogaster that require fascin activity, we identify a regulatory residue wi...
Background and purpose: Squamous cell carcinoma (SCC) is the eighth most common cancer in men and the fifteenth in women. Localized recurrence and metastasis to regional lymph nodes are major problems in these patients. Fascin is a 55- kDa protein from the family of actin-binding proteins that is expressed in cells with membranous bronchial tubes. The aim of this study was to evaluate the expre...
Introdouction: Oral squamous cell carcinoma (OSCC), the most common form of oral cancer, requires early diagnosis and suitable treatments. Fascin is a protein involved in cell adhesion and is increased in expression in certain types of carcinomas. The present study was conducted to assess fascin expression in OSCC using an immunohistochemical technique. Materials and methods: In the present re...
PURPOSE Fascin 2 is a retinal-specific member of the fascin family of actin filament-bundling proteins. Fascin 2 mutation in humans results in autosomal dominant retinitis pigmentosa or macular degeneration. To investigate the role of fascin 2 in photoreceptor survival, the authors examined its localization in photoreceptors and characterized its interactions with actin filaments in vitro. ME...
High expression of the actin bundling protein Fascin increases the malignancy of tumor cells. Here we show that fascin expression is up-regulated in more malignant sub-cell lines of MDA-MB-231 cells as compared to parental cells. Since also parental MDA-MB-231 cells exhibit high fascin levels, increased fascin expression was termed as "hyperexpression". To examine the effect of fascin hyperexpr...
PURPOSE Fascin, an actin bundling protein, induces membrane protrusions and increased cell motility in various transformed cells. The expression of fascin in epithelial neoplasms has been described only recently, and the role of fascin in esophageal squamous cell carcinoma (ESCC) is still unknown. EXPERIMENTAL DESIGN Paraffin sections of 200 patients with ESCC were immunohistochemically inves...
