ObjectiveThe current preferred treatment of ovarian cancer is combination chemotherapy, usually a platinum-based drug coupled with paclitaxel (PTX). Here, we investigated whether co-treatment with valproic acid (VPA) could increase the efficiency of various ovarian cancer drugs—PTX, doxorubicin (DOX), carboplatin (CBP), and cyclophosphamide (CP)—in different ovarian cancer cell lines.MethodsThree different ovarian cancer cell lines (OVCAR-3, TOV-21G, and TOV-112D) were treated with chemotherapeutic drugs, alone or in combination with VPA. Cell viability (XTT assay), caspase-3 activity, and the expression of cell cycle– and apoptosis-related genes and proteins were assessed. Furthermore, the effects of these drugs on α-tubulin acetylation and DNA fragmentation were investigated.ResultsPaclitaxel and DOX decreased cell viability and increased caspase-3 activity, and co-treatment with VPA enhanced this effect. Carboplatin and CP had no effect. Responses to treatment with PAX and DOX together with VPA on gene expression profile were highly variable and depended on the cell line investigated. However, a common feature in all cell lines was an increased expression ofCDKN1A,CCNE1,PARP1, andPARP3. Co-treatment with VPA enhanced the effect of DOX and PAX on most protein expressions investigated in TOV-21G and TOV-112D cell lines, whereas in OVCAR-3, the most effect was seen with DOX with VPA. Valproic acid did not increase PTX-induced α-tubulin acetylation. An additive effect of DOX with VPA on DNA fragmentation was observed in TOV-21G and TOV-112D cell lines but not in the OVCAR-3.ConclusionsOur results indicate that VPA could be a promising agent in combined anticancer therapy for ovarian cancer, with the combination of VPA and DOX being the most effective. Certainly, additional in vivo and ex vivo experiments are necessary to investigate the molecular mechanisms of action underlying the cellular effects reported here and to study possible clinically relevant effects in ovarian cancer explants.

ObjectiveCinobufotalin (CINO), a cardiotonic steroid (CTS) or bufadienolide, is extracted from the skin secretions of the traditional Chinese medicine giant toads (Chan su). CINO has been used as a cardiotonic, diuretic and a hemostatic agent. Previously we have shown that CINO inhibits the cytotrophoblast cell function. Recently other study has shown that CINO inhibits A549, a lung cancer cell function. In this study, we assessed the effect of CINO on three different ovarian cancer cell lines; SK-OV-3, CRL-1978 and CRL-11731 to confirm whether the effect of CINO is cell specific.Study DesignWe evaluated the effect of CINO on three ovarian cancer cells SK-OV-3, CRL-1978, and CRL-11731 function in vitro. Each Cell lines were treated with different concentrations of CINO (0.1, 1, 5 and 10 µM). For each cell line cell proliferation, migration and invasion were measured by using a CellTiter Assay (Promega), Cytoselect Assay (Cell Biolabs) and by using a FluoroBlock Assay (BD) respectively. Proliferating Cell Nuclear Antigen (PCNA) was also evaluated in cell lysates of CINO treated these 3 ovarian cancer cells by western blot analysis. Cell Cycle arrest and Cell viability were determined by fluorescence-activated cell sorting (FACS) analysis. We also performed Annexin V staining on CINO treated these 3 ovarian cancer cell lines by immunofluorescence to evaluate the pro-apoptotic protein expression. In addition mitochondrial membrane potential has also been measured for all these 3 ovarian cell lines after CINO treatment using MMP kit, by FACS analysis.ResultsConcentration of CINO at 0.5 µM inhibit SK-OV-3, CRL-1978, and CRL-11731 ovarian cancer cells proliferation, migration and invasion without cell death and loss of cell viability but cell viability differs for each cell line. Each cell lines differ in response to CINO doses for PCNA expression as well as Annexin V pro-apoptotic protein expression. CINO decreases mitochondrial membrane potential for SK-OV-3 but for CRL-1978 and CRL-11731 increases in response to CINO treatment.ConclusionCINO is cell specific, as each cancer cell line responds differently. These data demonstrate that the mode of action of CINO is different on these 3 types of ovarian cancer cells.
