objective: to evaluate the potentiality of ovcar–3 cell line of ovarian adenocarcinoma as a xenograft model for ovarian adenocarcinoma in nude mice. materials and methods: the cell line isolated from advanced human ovarian adenocarcinoma, were inoculated to eight nude mice and two months later. established tumors were transferred to pathology laboratory to be prepared by h&e; staining and immun...

leydig stromal cell tumor is a rare ovarian tumor that belongs to the group of sex-cord stromal tumors. they produce testosterone leading to hyperandrogenism. we present a 41yr old woman with symptoms of virilization and a mass of right adenex via ultra sonography, and a rise of total and free serum testosterone. an ovarian source of androgen was suspected and a surgery performed. a diagnosis o...

background: our preliminary data on the protein expression of sort1 in ovarian carcinoma tissues showed that sortilin was overexpressed in ovarian carcinoma patients and cell lines, while non-malignant ovaries expressed comparably lower amount of this protein. in spite of diverse ligands and also different putative functions of sortilin (ntr3), the function of overexpressed sortilin in ovarian ...

perivascular epithelioid cell tumor (pecoma) is a rare mesenchymal tumor composed of immunohistochemically and histologically distinctive perivascular epithelioid cells. here, we report on the computed tomography (ct) and magnetic resonance imaging (mri) findings of ovarian pecoma with pulmonary metastasis. the tumor was visible as a multilocular hemorrhagic mass that encased the ovarian vessel...

UNLABELLED BACKGROUND Cell lines are very useful for clinical and basic research. Thus far, only 11 reports have documented the characteristics of ovarian endometrioid adenocarcinoma cell lines in the literature. Due to the scarcity of information, the establishment of an ovarian malignant tumor cell line with distinctive characteristics is particularly important to study this disease. Thus,...

BACKGROUND Cell lines are very useful for both clinical and basic research. The establishment of ovarian, malignant tumor cell lines with aggressive histology is especially important. We describe the establishment and characterization of a new human clear cell carcinoma cell line of the ovary. RESULTS The cell line HCH-1 was established from an ovarian tumor from a 67-year-old woman. This cel...

background and aims: plants as medicines have always played a vital role in human life. tumor necrosis factor alpha (tnf)-α is one of the macrophage-derived inflammatory cytokine with pleotropic effects in the inflammation process. some studies have been demonstrated that some of the echinops species have anti-inflammatory activity. in fact, echinops lasilepis is introduced as one of the native...

objective: recent evidences suggest that tumors arise from a small subpopulation of cells, the cancer stem cells (cscs) or tumor initiating cells. cscs are able to resist the conventional methods of cancer therapy due to existence of abc transporters on their surface. this leads to csc resistance and maintenance resulting in post-treatment relapse and metastasis. therefore, precise identificati...
