Description:
The aim of our study was to determine the effect of selected cytostatics on a human ovarian cancer cell line A2780 as a model system for ovarian cancer treatment. This cell line is considered cisplatin-sensitive. Panel of tested cytostatics included cisplatin, paclitaxel, carboplatin, gemcitabine, topotecan and etoposide. These cytostatics have a different mechanism of action. To evaluate cytotoxic potential of the tested compounds, the methods measuring various toxicological endpoints were employed including morphological studies, MTT assay, dynamic monitoring of cell proliferation with xCELLigence, cell cycle analysis, caspase 3 activity and expression of proteins involved in cell cycle regulation and cell death. The A270 cell line showed different sensitivity towards the selected cytostatics, the highest cytotoxic effect was associated with paclitaxel and topotecan., Kateřina Caltová, Miroslav Červinka, and Literatura 38

Description:
Egg-oil (Charismon©) is known for its beneficial action in wound healing and other skin irritancies and its antibacterial activity. The physiological basis for these actions has been investigated using cells in culture: HaCaT-cells (immortalized human keratinocytes), human endothelial cells in culture (HUVEC), peripheral blood mononuclear lymphocytes (PBML) and a full thickness human skin model (FTSM). Emphasis was on the influence of egg-oil on cell migration and IL-8 production in HaCaT cells, respiration, mitochondrial membrane potential, reactive oxygen (ROS)production and proliferation in HUVEC and HaCaT cells, cytokine and interleukin production in PBML and UV-light induced damage of FTSM. IL-8 production by HaCaT cells is stimulated by egg-oil whilst in phythemagglutinin-activated PBMLs production of the interleukins IL-2, IL-6, IL-10 and IFN-γ and TFN-α is reduced. ROS-production after H<sub>2</sub>O<sub>2</sub> stimulation first is enhanced but later on reduced. Respiration becomes activated due to partial uncoupling of the mitochondrial respiratory chain and proliferation of HaCaT and HUVEC is reduced. Recovery of human epidermis cells in FTSM after UV-irradiation is strongly supported by egg-oil. These results support the view that egg-oil acts through reduction of inflammatory processes and ROS production. Both these processes are equally important in cellular aging as in healing of chronic wounds. and J. Bereiter-Hahn, A. Bernd, H. Beschmann, I. Eberle, S. Kippenberger, M. Rossberg, V. Strecker, N.
