Abstract The purpose of the present study is to investigate the cytotoxicity apoptotic effect of 2-chloro-2-deoxyadenosine, cladribine, 2-CdA ; in the human breast cancer cell line, MDA-MB468 estrogen receptor negative, ER- ; . MTT [3- 4, 5dimethyl-2-thiazolyl ; -2, 5-diphenyl-2H tetrazolium bromide] assay, annexin VFluorescein PI and Hoechst 33258 staining were used to detect cytotoxicity and cell apoptosis. The activation of caspase-3 and -9 was assayed using caspase activation assay kits. Gel electrophoresis was performed to detect DNA fragmentation. Treatment of MDA-MB468 cells with different concentrations of 2-CdA 50, 100 and 500 M ; resulted in a significant increase in the cell death. Annexin V-Fluorescein PI and Hoechst 33258 staining revealed that the cell death was mainly of apoptotic type. DNA laddering profile was also obtained in the treated MDA-MB468 cells using DNA fragmentation analysis. A significant p 0.05 ; increase in the activity of caspase-3 and -9 was observed. Pre-treatment of the cells with kinase inhibitor, 5-amino-5-deoxyadenosine inhibited the cytotoxicity effect of 2-CdA. This suggests that intracellular phosphorylation activation reaction plays a key role in the 2-CdA-induced apoptosis. In conclusion, this study showed that high dose of cladribine has an apoptotic effect on ER-MDA-MB468 breast cancer cells and its intracellular phosphorylation is necessary for cytotoxicity.
Clear data, model and computation stresses. Within this setting, we cannot currently answer question such as: "What would yield the most improved and timely predictionsmore or better data, better models, or more computation e.g., to explore multiple scenarios ; ?" Relating improved predictions to the costs not only monetary, but also in terms of time ; to the associated benefits would introduce risk considerations in settings in which they have hitherto been absent. Exposure assessment has long been a weakness of many risk analyses, because of the large unobserved variability. In some settings, such as environmental risk--a natural point of intersection with other SAMSI themes, the problems are well-recognized. However, they occur in other settings as well; for example, excessive exposure to nutrients can be dangerous, but existing means of estimating exposure are simply not effective at identifying at-risk individuals with extreme exposure. Even estimation of levels of extreme exposure raises non-standard issues. Model validation. This ubiquitous issue has special significance in risk analysis, since for some rare events whose risk must be assessed, there are no data. An example drawn from the SAMSI 200506 program on NDHS is an outbreak of foot and mouth disease among cattle in the US. The opportunity to link this working group with the 200607 SAMSI program on "Development, Assessment and Utilization of Complex Computer Models" is also attractive. Risk in the pharmaceutical industry. Although some may consider this topic too "specialized" for SAMSI, it is of broad interest. Issues raised at the ISU workshop included the increasing importance of nonrandomized clinical trials, 7 multiplicity8 and asymmetries between null and alternative hypotheses-- at the Food and Drug Administration FDA ; and elsewhere. Elicitation of expert opinion. It is well-recognized that the "data" underlying many risk analyses constitute expert opinions rather than conventional measurements. Despite ongoing attention to eliciting and incorporating expert opinion, there do not seem to be effective, available tools. The "less certain" potential working groups, in part because leaders are less apparent, are: are: Modeling resource allocation decisions by multiple stakeholders. In many contexts Hurricane Katrina provides one ; , decisions to mitigate future risks are made by multiple stakeholders e.g., federal, state and local governments ; , but methods do not exist to integrate these decisions. Existing decisiontheoretic abstractions and tools may not be adequate to deal with these problems. Multiscale risk analysis. Risks exist on multiple time and space scales, but no good methods exist for addressing multiscale risks. Previous SAMSI programs on multiscale modeling and data assimilation may have initiated threads of research that are relevant to this problem. Risk perception. An especially challenging issue is the increasing divergence between risk perception and risk reality. For example, based on numbers of deaths, in most years it is more dangerous to drive to the airport than to fly. ; Tools to communicate and visualize risk represent a research as well as a policy need. A particular intriguing problem is interactions among the risk receptions of related individuals e.g., members of the same household, or employees of the same company ; . Relevant ideas come from existing research on risk perceptions of individuals, group decision and social networks.9.
