The use of chemotherapy to treat cancer is effective, but chemoresistance reduces this efficacy. Chemotherapy resistance involves several mechanisms, including the cancer stem cell (CSC) concept. The aim of the present study was to assess whether paclitaxel-resistant epithelial ovarian carcinoma is capable of generating cells with CSC-like properties. Using the paclitaxel-resistant A2780/PTX ce...
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 ...
Different types of Artemisia aucheri extracts were reported to have various biological activities including a cytotoxic effect on some cancer cell lines. We investigated the antiproliferative activity of isolated sesquiterpenoids from petroleum ether extract of Artemisia aucheri (A. aucheri)aerial parts on SK-N-MC, MCF-7, and A2780 cell lines. Phytochemicals from the petroleum ether cold macera...
Reactive oxygen species are tumorigenic by their ability to increase cell proliferation, survival, and cellular migration. The purpose of the present study was to compare the antioxidant activity and cytotoxic effects of 3 berry extracts (strawberry, Korean raspberry, and mulberry) in A2780 human ovarian carcinoma cells. Except for raspberry, the ethyl acetate or methylene chloride fractions of...
Background & aim: Due to the presence of high amounts of compounds with antioxidant and cytotoxic properties in Foeniculum vulgare mill seed essential oil, the aim of this study was to investigate the toxicity of Foeniculum vulgare mill seed essential oil on MCF-7 breast cancer cell line and A2780 ovarian cancer cell line and to investigate the antioxidant activity of the essential oil of this ...
We have examined the relationship between cis-diamminedichloroplatinum(II) (cisplatin) resistance and replicative bypass in the human ovarian carcinoma cell lines 2008, A2780, and their respective cisplatin-resistant derivatives C13* and A2780/DDP. Replicative bypass is defined as the ability of a replication complex to proceed past a DNA adduct known to block or stall the complex during synthe...
Brostallicin (PNU-166196) is a synthetic alpha-bromoacrylic, second-generation DNA minor groove binder structurally related to distamycin A, presently in Phase II trials in Europe and the United States. The compound shows broad antitumor activity in preclinical models and dramatically reduced in vitro myelotoxicity in human hematopoietic progenitor cells compared with that of other minor groove...
The antiproliferative activity of a set of seven natural Amaryllidaceae alkaloids and 32 derivatives against four cancer cell lines (A2780, SW1573, T47-D and WiDr) was determined. The best antiproliferative activities were achieved with alkaloids derived from pancracine (2), haemanthamine (6) and haemantidine (7). For each skeleton, some structure-activity relationships were outlined.
Whether or not inhibition of NFkappaB increases the efficacy of cisplatin in in vitro and in vivo ovarian cancer models was investigated. We compared the basal levels of phosphorylation of IkappaBalpha and activity of NFkappaB between cisplatin-sensitive A2780 cells and cisplatin-resistant Caov-3 cells. The basal levels of phosphorylation of IkappaBalpha and activity of NFkappaB in Caov-3 cells...
