Initiation of cell growth and neoplastic transformation frequently involves activation of growth factor receptor-coupled tyrosine kinases and stimulation of the phosphoinositide second messenger system. Altered expression of CD44 variants was reported in several malignant tumor types with possible implications for tumor progression and prognosis. CD44 variant expression was reported to be assoc...

The adhesion of cancer cells to vascular endothelium is a critical process in hematogenous metastasis and might be similar the recruitment leukocytes at site inflammation. It mediated by E-selectin its ligands, which most stereospecific glycoconjugate sialyl Lewis x (CD15s), may expressed as an oligosaccharide branch CD44 glycoprotein, well self-contained glycosphingolipid. also known that incr...

OBJECTIVES CD44 is a member of the cell adhesion molecules family. Naturally, CD44S, along with CD44V3 influence the cell motility, migration, and adhesion, while in tumor cells they lead to tumor invasion, progression, and metastasis. The purpose of this research is to evaluate the CD44S and CD44V3 expression in Esophageal Squamous Cell Carcinoma (ESCC) and to reveal their correlations with cl...

Immunohistochemical screening of pancreatic adenocarcinomas from 24 different patients and 9 pancreatic carcinoma cell lines revealed variant CD44 expression in all specimens tested. In contrast to normal pancreatic tissue, carcinomas were strongly positive for epitopes encoded by variant exons v5, whereas v6 was expressed on carcinoma cells as well as normal ductal pancreatic cells. Analysis o...

CD44 isoforms belong to a family of cell adhesion molecules expressed on the cell surface of many tumor cells during human breast cancer progression. In this study we have analyzed the expression of CD44v3-containing isoforms [containing heparan sulfate addition sites for growth factor binding] in primary breast tumors, axillary nodal metastases and normal breast tissue. Using reverse transcrip...

The need for antibody proteins is growing both diagnosis and therapy. In this work, we combine two strategies based on single nanopore sensing multipore membrane to separate, detect identify antibodies. This proof of concept was done the anti-CD44. a first step, with bullet shape were designed using track-etching polymer film functionalized, PEG spacer CD44 antigen. detection anti-CD44 evidence...
