Abstract :-
Breast cancer is widely spreaded type of cancer in women and responsible for high number of cancer death in women. Taxol has been already approved to be used for breast cancer by FDA. There have been several studies on the anti tumor activities of Vitamin E Succinate (VES) as complementary and alternative medicine. In present study, we investigated the cytotoxic effect of taxol-VES combination on MCF-7 breast cancer cell lines in comparison with taxol alone. MCF-7 cells are preffered because of higher sensitivity to estogens. MCF-7 cells were sub cultured in according to specifications of aseptic conditions by incubating at 37οC and 5%CO2. Cells were seeded in 24 well plate with culture medium and different concentration of different drug regimen ( taxol alone, VES alone, taxol-VES combination) for 72hrs. Cell viability can be checked by MTT cell viability assay. MTT assay uses a MTT dye which acts as a substrate for viable cell reductase enzyme. This enzyme reduces MTT yellow dye to purple colour formazan which is in proportional to viable cell eventually. The intensity of purple colour was measured by measuring absorbances at 570nM using spectrophotometer. The results of the study were plotted as %cell viability Vs concentration for each of three drug regimen. IC50 values for each drugs were calculated. Graphical and statistical analysis of results concluded that taxol-MCF combination has more inhibitory effect on MCF-7 breast cancer cell lines when treated for 72hrs in comparison with taxol alone and statistical analysis had concluded that results were significant enough to accept clinically to use in stratagic breast cancer therapy management.
