CD10 and MUM1 are representative B cell differentiation markers. Follicular lymphoma (FL) is usually positive for CD10 and negative for MUM1. In this study, however, we compared 22 FLs with peculiar phenotype CD10-MUM1+ with 119 typical CD10+MUM1- FLs. All CD10-MUM1+ FL patients exhibited follicular structure with follicular dendritic meshwork, and a high rate of somatic hypermutation and ongoi...

CD10 expression in various grades and interfollicular infiltrates of follicular lymphoma (FL) has not been well documented. Immunohistochemical staining for CD10 (clone 56C6) was performed on paraffin-embedded tissue from 26 cases of classic FL. Negative or weak expression of CD10 was more frequent in grade III (5/6 [83%]) than in grade I FLs (3/15 [20%]). CD10+ interfollicular infiltrates were...

The cell membrane-associated enzyme CD10/neutral endopeptidase 24.11 (CD10/NEP) functions in multiple organ systems to downregulate responses to peptide hormones. Recently, CD10/NEP was found to hydrolyze bombesin-like peptides (BLP), which are mitogens for normal bronchial epithelial cells and small cell lung carcinomas. Growth of BLP-responsive small cell lung carcinomas was potentiated by CD...

We compared susceptibility to Candida vaginitis in derived murine substrains differing in sensitivity to estrogen (CD-1 and CD10, resistant; CD3 and C57BL/6 responsive), and in F1 crosses. The order of decreasing resistance was CD-1 > or = CD10 > or = CD10 x CD3F1 > CD10 x B6F1 > CD3 > C57BL/6 and correlated with estrogen responsiveness in endocrine disruptor assays. Resistance to Candida vagin...

CD10 is a cell surface endopeptidase that inactivates various potentially growth stimulatory peptides. In lung cancer cell lines this downregulation has been associated with increased proliferation. Downregulation of CD10 in lung cancer tissue is described, suggesting a potential role in carcinogenesis and a possible use of CD10 as a prognostic marker. We aimed to determine the rate of CD10 exp...

AIM Previous studies reported that CD10 positive Colorectal Cancer Cells (CRC) characterized by deeply invasive neoplasia. MATERIALS AND METHODS We have examined 50 pts surgically treated for colorectal cancer on at least 5 years follow up. TNM, grading score and survival have been compared to CD10 expression. RESULTS Thirty-four out of fifty cases have been analyzed (18 males and 16 female...

PURPOSE Neutral endopeptidase (CD10), an ectopeptidase bound to the cell surface, is thought to be a potential prognostic marker for prostate cancer. EXPERIMENTAL DESIGN Prostate cancer patients (N = 3,261) treated by radical prostatectomy at a single institution were evaluated by using tissue microarray. Follow-up data were available for 2,385 patients. The cellular domain (membranous, membr...

CD10 has been widely used in cancer diagnosis. We previously demonstrated that its expression in melanoma increased with tumor progression and predicted poor patient survival. However, the mechanism by which CD10 promotes melanoma progression remains unclear. In order to elucidate the role of CD10 in melanoma, we established CD10-overexpressing A375 melanoma cells and performed DNA microarray a...

BACKGROUND CD10 is a cell surface metalloproteinase expressed by a variety of normal cell types, including lymphoid precursor cells, germinal center B lymphocytes and some epithelial cells. Although accumulating data indicate that CD10 expression by stromal cells is involved in colorectal carcinogenesis and it is a novel prognostic factor in breast carcinoma, CD10-positive stromal cells and the...

This study shows that human postthymic T cells express CD10 when undergoing apoptosis, irrespective of the signal responsible for initiating the apoptotic process. Cells from continuous T-cell lines did not normally express CD10, but became CD101 when induced into apoptosis by human immunodeficiency virus (HIV) infection and exposure to CD95 monoclonal antibody, etoposide, or staurosporin. Inhi...
