PURPOSE The synthetic retinoid fenretinide (4-HPR) exhibits preventive and therapeutic activity against ovarian tumors. An unidentified polar metabolite was previously found in 4-HPR-treated subjects and in A2780 human ovarian carcinoma cells continuously treated with 4-HPR (A2780/HPR). The metabolite and the enzyme involved in its formation in tumor cells are herein identified. EXPERIMENTAL ...
Sørensen BH, Thorsteinsdottir UA, Lambert IH. Acquired cisplatin resistance in human ovarian A2780 cancer cells correlates with shift in taurine homeostasis and ability to volume regulate. Am J Physiol Cell Physiol 307: C1071–C1080, 2014. First published September 24, 2014; doi:10.1152/ajpcell.00274.2014.—Cisplatin resistance is a major challenge in the treatment of cancer and develops through ...
BACKGROUND Drug resistance and tumor metastasis are the main causes of treatment failure and mortality in cancer patients. Silibinin, a naturally occurring flavanone, has been shown to be a potent sensitizer for apoptosis induced by a variety of anticancer drugs. In this study, whether silibinin could overcome chemoresistance and reduce the invasiveness of A2780/taxol cells was investigated. ...
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...
Drug resistance remains an on-going challenge in ovarian cancer chemotherapy. The objective of this study was to determine the effect on synergism in activity from the sequenced combinations of cisplatin (Cis) with curcumin (Cur) and epigallocatechin-3-gallate (EGCG) in the human ovarian cancer cell lines. The drugs were added in binary combinations: Cis combined with Cur, and Cis combined with...
Cisplatin resistance is one of the major reasons leading to the high death rate of ovarian cancer. Methyl-Capture sequencing (MethylCap-seq), which combines precipitation of methylated DNA by recombinant methyl-CpG binding domain of MBD2 protein with NGS, global and unbiased analysis of global DNA methylation patterns. We applied MethylCap-seq to analyze genome-wide DNA methylation profile of c...
Erythropoietin (Epo) is a key regulator of erythroid cell proliferation, differentiation and apoptosis. In the form of the recombinant protein, it is widely used to treat various types of anemias, including that associated with cancer and with the myelosuppressive effects of chemotherapy, particularly platinum-based regimens. Our previous studies confirmed the presence of Epo receptors (EpoRs) ...
BACKGROUND Berberine, a well-known component of the Chinese herbal medicine Huanglian, has wide range of biochemical and pharmacological effects, including antineoplastic effect, but the exact mechanisms remain unclear. The aim of the present study was to evaluate the potential chemo-sensitization effect of berberine in ovarian cancer cell line A2780. METHODS The expression of miR-93 was meas...
Ovarian cancer (OC) is most often contained within the peritoneal cavity, making it an ideal disease for adenoviral-delivered gene therapies. In effort to develop a safe and effective gene therapy for OC, we created a replication deficient adenovirus bearing the herpes simplex thymidine kinase (HSV-tk) gene under direction of the tumor specific promoter human epididymis protein 4 (HE4). The pur...
CLN3 is a recently identified anti-apoptotic gene, which has been demonstrated to be highly expressed in a diverse range of cancer cell lines, including ovarian cancer. In the present study, RNA interference, mediated by a lentivirus expressing CLN3 short hairpin RNA (shRNA) was utilized to knockdown the expression of CLN3 in the A2780 human ovarian cancer cell line, and its cisplatin‑resistant...
