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 ...
BACKGROUND Calcineurin B homologous protein isoform 2 (CHP2) was identified to be expressed in various malignant cell lines including ovarian cancer, but not in the normal tissue counterpart. The biological function of CHP2 related to cancer progression is still unknown. MATERIALS AND METHODS A CHP2-negative human epithelial ovarian cancer cell line OVCAR3 was used for this study. CHP2 was an...
MicroRNAs (miRNAs) are involved in regulating the response of cancer cells to various therapeutic interventions, yet their involvement in the chemoresistance of human epithelial ovarian cancer is not fully understood. We found that miR-136 was significantly downregulated in specimens from patients with chemoresistant epithelial ovarian cancer. In the present study, we aimed to clarify the role ...
Drug resistance enables cancer cells to break away from cytotoxic effect of anticancer drugs. Identification of resistant phenotype is very important because it can lead to effective treatment plan. There is an interest in developing classifying models of resistance phenotype based on the multivariate data. We have investigated a vibrational spectroscopic approach in order to characterize a...
Ovarian cancer is the third most common cancer in the female reproductive organs and epithelial ovarian cancer has the highest lethality of all gynecological cancers. Pomegranate fruit juice (PFJ) has been shown to inhibit the growth of several types of cancer other than ovarian cancer. In this study, we exposed the ovarian cancer cell line A2780 to PFJ and two of its components (ellagic acid a...
Vaccination with embryonic stem cells generates effective antitumor immunity against ovarian cancer.
To date, only a few studies have suggested that human embryonic stem cells (hESCs) might effectively immunize against colon and lung cancer. The purpose of this study was to investigate the therapeutic potential of hESCs as a vaccine to induce widespread antitumor effects in different animal models and various types of cancer. C57BL/6 mice with ID...
The development of ovarian cancer, unlike that of most human tumors, is rarely dependent upon the mutually exclusive loss of RB and p16 cell cycle proteins. RB+/p16+ ovarian cancer cell lines are, however, insensitive to the growth-suppressive effects of ectopically expressed p16 protein, which suggests that they harbor as yet unidentified defects that compromise cell cycle regulation in late G...
background: monoclonal antibodies (mabs) are essential tools for many molecular im-munology investigations, epitope mapping and molecular modelling, clinical laboratory di-agnostic tests and immunotherapy. humoral immune response of immunized animals largely depends on the nature of antigen and the immunization technique. polysaccharides and heavily-glycosylated proteins are very elusive target...
Background and Aims: Magnetic resonance imaging (MRI) plays an essential role in molecular imaging by delivering the contrast agent into targeted cells. The aim of this study was to evaluate the use of magnetic nanoparticles containing iron oxide and silver (Fe3O4@Ag core-shell nanoprobe) as a contrast agent for the detection of ovarian cancer cell line ovcar-3. Materials and Methods: Co-preci...
background ovarian cancer is the most common fatal gynecologic malignancy in women. the brca2 gene has a role in regulation of cell cycle during proliferation, differentiation and dna repair. changes in the methylation of brca2 may be an effective mechanism for ovarian cancer. objectives the aim of the present study was to evaluate the association between ovarian cancer and methylation status o...
