Objective: Aldehyde dehydrogenase (ALDH) enzymatic activity identifies ovarian cancer stem-like cells. We investigated the antineoplastic activity of the ALDH inhibitor Disulfiram on bulk ovarian cancer cells and CD133+/ALDH+ cancer stem-like cells. Study Design: Ovarian cancer cell lines, human ovarian surface epithelial cells, and mesenchymal stem cells were treated with increasing concentrat...
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 c...
Ovarian small cell carcinoma is a rare and highly malignant tumor with poor prognosis. It usually presents in younger females with features of hypercalcemia. The exact histogenesis of the tumor is unclear and it may present as an undifferentiated tumor. In such cases, immunohistochemistry (IHC) plays an important role to confirm the diagnosis. Limited treatment options are available and mainly ...
Cytokines protein or glycoproteins synthesized by a wide range of cell types including lymphocytes, macrophages, platelets, and monocytes. Cytokines induse synthesis of acute phase protein in hepatocytes. So far eight cytokines has been shown can induce acute phase protein synthesis in hepatocyte and hepatoma cell culture. There are evidences that transforming growth factor-alpha (TGF-a) secr...
Previous studies indicated that a new member of the human kallikrein (KLK) gene family, KLK4, was expressed in prostate, breast, and endometrial carcinoma cell lines and may have potential as a tumor marker. The aim of this study was to examine the expression of KLK4 in the normal ovary and ovarian tumors of different histology, stage, and differentiation and to determine its association with o...
BACKGROUND The role of estrogen and progesterone in ovarian carcinogenesis and the growth and survival of ovarian cancer cells is controversial. In this study, we tested the effects of various concentrations of estrogen and progesterone on the survival of an ovarian cancer cell line. METHODS The ovarian adenocarcinoma cell line, OC-117-VGH, is deficient in the following receptors: estrogen re...
Mature cystic teratoma (MCT) is the most common type of ovarian germ cell tumor occurring in females of reproductive age. It is typically benign, but rare malignant transformations have been reported in 1-2% of the cases. Among a wide variety of malignancies arising in MCTs, high grade lymphomas are the least common. We present a case of a 45- years -old female with a unilateral adnexal ma...
PURPOSE Cisplatin and its platinum derivatives are first-line chemotherapeutic agents in the treatment of ovarian cancer; however, treatment is associated with tumor resistance and significant toxicity. Here we investigated the antitumoral activity of lipoplatin, one of the most promising liposomal platinum drug formulations under clinical investigation. EXPERIMENTAL DESIGN In vitro effects o...
To determine the efficacy of a novel and safer (for gastrointestinal tract) aspirin (aspirin-PC) in preclinical models of ovarian cancer, in vitro dose-response studies were performed to compare the growth-inhibitory effect of aspirin-PC versus aspirin on three human (A2780, SKOV3ip1, and HeyA8) and a mouse (ID8) ovarian cancer cell line over an 8-day culture period. In the in vivo studies, the...
