ovarian cancer is the most lethal gynecological cancer in which cisplatin-based treatment plays fundamental role as the first line chemotherapy option. however, development of platinum-resistance is a critical and poorly understood problem in ovarian cancer treatment. although in vitro generation of platinum-resistant ovarian cancer cell lines is a long established approach to uncover the molec...

Background and objectives: Black cumin is a herbaceous plant with scientific name Nigella sativa, that contains compounds such as fixed oils, proteins, alkaloids, saponins and essential oils. It has numerous health benefits including antioxidant and anti-inflammatory properties. In the current study, we have evaluated the cytotoxic effects of compounds isolated from th...

Objective(s): Multidrug resistance (MDR) is a major obstacle in the successful chemotherapy of ovarian cancer. Inhibition of P-glycoprotein (P-gp), a member of ATP-binding cassette (ABC) transporters, is a well-known strategy to overcome MDR in cancer. The aim of this study was to investigate the efficiency and ability of CRISPR/Cas9 genome editing technology to knockdown ABCB1 gene expression ...

Olea europaea L. commonly known as olive has been traditionally used for the prevention and treatment of many diseases since ancient times. Olive has been reported to possess a broad spectrum of pharmacological properties. In the present study we investigated the activity of aqueous extract of Olea europaea L. fruit at various concentrations on A2780, A172 and HFFF2 cell lines proliferation by ...

Objective(s): Crocetin, one of the main substances of saffron extract, has anti-cancer effects. Drug resistance proteins (e.g. MRP1 and MRP2) are important reasons for the failure of cancer therapy. We intended to investigate the efficacy of crocetin on MRP1 and MRP2 activity in human ovarian cisplatin-resistant carcinoma cell line (A2780-RCIS).Materials and Methods: The cytotoxic effect of cro...

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 sen...

Low efficiency of chemotherapy in ovarian cancer results from the development of drug resistance. Cisplatin (CIS) and topotecan (TOP) are drugs used in chemotherapy of this cancer. We analyzed the development of CIS and TOP resistance in ovarian cancer cell lines. Incubation of drug sensitive cell lines (W1 and A2780) with cytostatic drugs was used to determine the primary response to CIS and T...
