BACKGROUND CD44 is a molecular marker associated with cancer stem cell populations and treatment resistance in glioma. More effective therapies will result from approaches aimed at targeting glioma cells high in CD44. METHODS Glioma-initiating cell lines were derived from fresh surgical glioblastoma samples. Expression of tissue transglutaminase 2 (TGM2) was attenuated through lentivirus-medi...
Purpose: Gastric cancers may harbor a subset of cells with cancer stem cell (CSC) properties, including chemotherapy resistance, and CD44 is a gastric CSC marker. The Hedgehog (HH) pathway is a key developmental pathway that can be subverted by CSCs during tumorigenesis. Here, we examine the role of HH signaling in CD44(þ) gastric cancer cells. Experimental Design: Gastric cancer cell lines, tu...
CD44 molecule is a cell surface glycoprotein involved in many cell-cell and cell-matrix interactions. Circulating serum CD44 (s-CD44) levels have been found to change in parallel with response to therapy, but little is known about the predictive or prognostic significance of s-CD44. In the present study, we measured s-CD44 levels in sera taken before treatment from 194 patients with non-Hodgkin...
BACKGROUND Human prostate basal cells expressing alpha-6 integrin (CD49f(Hi)) and/or CD44 form prostaspheres in vitro. This functional trait is often correlated with stem/progenitor (S/P) activity, including the ability to self-renew and induce differentiated tubules in vivo. Antigenic profiles that distinguish tubule-initiating prostate stem cells (SCs) from progenitor cells (PCs) and mature l...
We previously found that the CD44 glycoprotein on some lymphocytes can mediate adhesion to hyaluronate (HA) bearing cells. However, many questions remain about the molecular heterogeneity of CD44 and mechanisms which control its recognition of this ligand. In vitro mutagenesis and DNA sequencing have now been used to investigate the importance of the membrane proximal region of murine CD44 for ...
Hepatocellular carcinoma (HCC) is the second leading cause of cancer deaths in Taiwan. CD44, one of the well-known tumor markers, plays an essential role in tumor cell differentiation, invasion, and metastasis. We investigated the CD44 single-nucleotide polymorphisms (SNPs) with environmental risk factors related to HCC susceptibility and clinicopathological characteristics. Six SNPs of CD44 we...
Diverse receptors, including Fcgamma receptors and beta(2) integrins (complement receptor-3 [CR3], CD11b/CD18), have been implicated in phagocytosis, but their distinct roles and interactions with other receptors in particle engulfment are not well defined. CD44, a transmembrane adhesion molecule involved in binding and metabolism of hyaluronan, may have additional functions in regulation of in...
Cancer stem cells (CSC) are associated with tumor resistance and are characterized in gastric cancer (GC). Studies have indicated that Notch and wnt-beta-catenin pathways are crucial for CSC development. Using CD44+ CSCs, we investigated the role of these pathways in GC carcinogenesis. We performed cell proliferation, wound healing, invasion, tumorsphere, and apoptosis assays. Immunoblot analys...
BACKGROUND CD44 and phosphorylated AKT (p-AKT) is a potentially interesting prognostic marker and therapeutic target in pancreatic cancer. The expression of CD44 and p-AKT has been reported to correlate with poor prognosis of pancreatic cancer in most literatures. The purpose of this study is to investigate the roles of CD44 and p-AKT in pancreatic head cancer and their correlation with the pro...
Localization of circulating lymphocytes to a site of inflammation is paramount for the development and maintenance of an immune response. In vitro studies using cell lines have previously demonstrated that rolling and adhesion of lymphocytes on endothelium requires CD44 interactions with hyaluronan (HA). To date, whether CD44 has a role in mediating CD4(+)-polarized T-helper 1 (Th1) and Th2 lym...
