OBJECTIVE The identification of cancer stem-like cells is a recent development in ovarian cancer. Compared to other cancer cells, cancer stem-like cells present more chemo-resistance and more aggressive characteristics. They play an important role in the recurrence and drug resistance of cancer. Therefore, the target therapy of cancer stem-like cell may become a promising and effective approach...

nloaded distal-less homeobox gene (dlx) 5 encodes a transcription factor that controls jaw formation and dage differentiation during embryonic development. We had previously found that Dlx5 is overexpressed Akt2 transgenic model of T-cell lymphoma. To investigate if DLX5 is involved in human cancer, we ed its expression in the NCI 60 cancer cell line panel. DLX5 was frequently upregulated in ce...

Receptor for Advanced Glycation Endproducts (RAGE) is expressed in ovarian tissue and associated with ovarian carcinoma. With a radiolabeled anti-RAGE antibody, we proposed to show extent of RAGE expression in animal model and effect of blocking RAGE on ovarian cancer cell growth. Methods: We measured inhibition of p-Akt and p-stat3 in SKOV-3 human ovarian carcinoma cell line and measured cell ...

BACKGROUND/AIMS FOXC2 has been reported to play a role in tumor progression, but the correlations of FOXC2 with the cisplatin (CDDP) resistance of ovarian cancer cells are still unclear. The purpose of the present study is to investigate the roles of FOXC2 in the CDDP resistance of ovarian cancer cells and its possible mechanisms. METHODS Quantitative real-time PCR (qRT-PCR) was performed to ...

Defective expression of HLA class I molecules is common in tumor cells and may allow escape from CTL-mediated immunity. We here investigate alterations in expression of HLA class I and their underlying molecular mechanisms in ovarian cancer patients. The HLA class I and HLA-A2 expression levels on noncultured tumor cells of 12 patients diagnosed with ovarian carcinoma were investigated by flow ...

abstract gastrointestinal mesenchymal tumors are a group of tumors originating from the mesenchymal stem cells of the gi tract. digestive tract schwannomas are rare mesenchymal tumors which occur most frequently in the stomach. we report a 56-yearold woman who was examined endoscopically for dyspepsia which she had suffered from since 3 years ago. around gastric antral mass was seen. surgical r...

PURPOSE The tetraspan protein epithelial membrane protein-2 (EMP2) has been shown to regulate the surface display and signaling from select integrin pairs, and it was recently identified as a prognostic biomarker in human endometrial cancer. In this study, we assessed the role of EMP2 in human ovarian cancer. EXPERIMENTAL DESIGN We examined the expression of EMP2 within a population of women ...

OBJECTIVE Only a small number of comprehensively characterized immortalized ovarian cancer cell lines are available for laboratory studies on ovarian cancer. We describe a new ovarian cancer cell line that arose from primary culture of a stage IC, grade III ovarian carcinoma, designated CSOC 882. METHODS We characterized CSOC 882 by karyotyping, growth modeling, immunohistochemical staining, ...

Steroid cell tumors account for less than 0.1% of all ovarian tumors. There are three steroid cell tumor subtypes: steroid cell tumor not otherwise specified (NOS), stromal luteoma and Leydig cell tumor. Steroid cell tumor, NOS, is the most common type and has malignant potential. This report describes a case of an ovarian steroid cell tumor, NOS. A 35-year-old woman visited hospital with the c...
