INTRODUCTION 90% of the tumors in the head and neck are squamous-cell carcinomas (HNSCC), which have overall 5- year survival rate between 50% -60%. CD44 has been shown to be associated with the prognosis. MATERIALS AND METHODS Biopsy specimens of 51 patients with oral tongue SCC were evaluated by Immunohistochemistry (IHC) for the CD44 antibody. RESULTS There was no significant correlation...

CD44 is a well-recognized stem cell biomarker expressed in colon and gastric cancer. In order to identify whether CD44 mRNA could be used as a prognostic marker in colon and gastric cancer, bioinformatic analyses were used in this study. cBioPortal analysis and COSMIC analysis were used to explore the CD44 mutation. CD44 mRNA levels were evaluated by using SAGE Genie tools and Oncomine analysis...

Soluble CD44 is present in the serum of normal individuals (2.7 +/- 1.1 nM). The concentration of soluble CD44 in the serum is elevated in patients with advanced gastric (24.2 +/- 9.8 nM) or colon cancer (30.8 +/- 11 nM). Serum CD44 concentration correlated with tumor metastasis and tumor burden. Surgical resection of tumors resulted in decreases in serum CD44 levels. By Western blot analysis, ...

Soluble CD44 is present in the serum of normal individuals (2.7 +_ 1.1 riM). The concentration of soluble CD44 in the serum is elevated in patients with advanced gastric (24.2 + 9.8 riM) or colon cancer (30.8 411 riM). Serum CD44 concentration correlated with tumor metastasis and tumor burden. Surgical resection of tumors resulted in decreases in serum CD44 levels. By Western blot analysis, mon...

The p53 tumor suppressor is a key mediator of cellular responses to various stresses. Here, we show that under conditions of basal physiologic and cell-culture stress, p53 inhibits expression of the CD44 cell-surface molecule via binding to a noncanonical p53-binding sequence in the CD44 promoter. This interaction enables an untransformed cell to respond to stress-induced, p53-dependent cytosta...

CD44 is commonly used as a cell surface marker of cancer stem-like cells in epithelial tumours, and we have previously demonstrated the existence of two different CD44(high) cancer stem-like cell populations in squamous cell carcinoma, one having undergone epithelial-to-mesenchymal transition and the other maintaining an epithelial phenotype. Alternative splicing of CD44 variant exons generates...

PURPOSE Human tumors consist of heterogeneous populations of cells with distinct marker expression and functional properties. In squamous cell carcinoma of the head and neck (SCCHN), CD44 is a well-characterized marker of a resilient subpopulation of cells associated with increased tumorigenesis, radioresistance, and chemoresistance. Evidence indicates that these cells have an immunosuppressive...

AIMS The aim of the present study is to investigate the differential expression of CD44, CD47 and c-met in ovarian clear cell carcinoma (OCCC), the correlation in their expression and their relationship with the biological behavior of OCCC. METHODS We used immunohistochemistry to examine the expression of CD44, CD47 and c-met in OCCC (86 cases) and investigated the effects of the expression a...

There is increasing evidence that cancer contains cancer stem cells (CSCs) that are capable of regenerating a tumor following chemotherapy or radiotherapy. CD44 and CD133 are used to identify CSCs. This study investigated non-invasive in vivo monitoring of CD44-positive cancer stem-like cells in breast cancer by γ-irradiation using molecular image by fusing the firefly luciferase (fLuc) gene wi...

CD44 and prostate stem cell antigen (PSCA) have been investigated as two biomarkers for various cancers. However, either CD44 or PSCA expression alone has limited clinical value. In the present study, the expression of CD44 and PSCA in human pancreatic ductal adenocarcinoma (PDAC) and their values in prognosis were investigated by immunohistochemistry (IHC) and Kaplan-Meier method. The results ...
