The development of cisplatin drug resistance remains a chief concern in ovarian cancer chemotherapy. β-Elemene is a natural plant product with broad-spectrum antitumor activity towards many types of carcinomas. This study aimed to define the biological and therapeutic significance of β-elemene in chemoresistant ovarian cancer. In the present study, β-elemene significantly inhibited cell growth ...

we aimed to develop a cost-effective and robust method to predict drug resistance in individualpatients. representative tissue fragments were obtained from tumors removed from femalepatients, aged 24-74 years old. the tumor tissue was taken by a histopathology’s or a surgeonunder sterile conditions. cells obtained by enzymatic dissociation from tumor after surgery, werecultured as a monolayer f...

BACKGROUND A crucial step in the metastatic spread of ovarian cancer (OC) is the adhesion and implantation of tumor cells to the peritoneal mesothelium. In order to study this step in the cascade, we derived a pro-metastatic human ovarian carcinoma cell line (MFOC3) from the non-metastatic FOC3 line. METHODS Molecular profiling of the isogeneic lines identified differentially expressed genes,...

Ovarian cancer remains the leading cause of fatality among all gynecologic cancers, although promising therapies are in the making. It has been speculated that metastasis is critical for ovarian cancer, and yet the molecular mechanisms of metastasis in ovarian cancer are poorly understood. Growth factors have been proven to play important roles in cell migration associated with metastasis, and ...

Ovarian cancer affects >295,000 women worldwide and is the most lethal of gynaecological malignancies. Often diagnosed at a late stage, current research efforts seek to further molecular understanding its aetiopathogenesis development novel biomarkers. The present study investigated expression levels glucogenic hormone asprosin [encoded by fibrillin?1 (FBN1)], cognate receptor, olfactory rec...

Ascitic fluid and plasma from ovarian cancer patients, but not from patients with nongynecological tumors, contain elevated levels of the bioactive phospholipid lysophosphatidic acid (LPA). We show that ovarian cancer cells constitutively produce increased amounts of LPA as compared with normal ovarian epithelium, the precursor of ovarian epithelial cancer, or breast cancer cells. In addition, ...

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...

MicroRNAs (miRNA) regulate complex patterns of gene expression, and the relevance of altered miRNA expression to ovarian cancer remains to be elucidated. By comprehensively profiling expression of miRNAs and mRNAs in serous ovarian tumors and cell lines and normal ovarian surface epithelium, we identified hundreds of potential miRNA-mRNA targeting associations underlying cancer. Functional over...

OBJECTIVE Although aspirin has been associated with a reduction of the risk of cancer when used as a nonsteroidal anti-inflammatory drug, its use to reduce the risk of ovarian cancer is controversial. Ovarian cancer cells usually express high levels of cyclooxygenase-1 (COX)-1. Because aspirin is a rather selective inhibitor of COX-1, the ability of aspirin to reduce the risk of ovarian cancer ...
