(A) Dose-dependent survival of MCF-7 cells treated with zerumbone as determined by MTT assay. A higher reduction of MCF-7 cell growth was found at a higher concentration of zerumbone. (B) Dose-dependent survival of MCF-7 cells treated with paclitaxel as determined by MTT assay. Different treatment periods exhibit differential sensitivities to paclitaxel treatment in vitro. Dose-response curves were obtained using a logistic nonlinear regression analysis model. (C) Dose-dependent survival of MCF-10A cells against zerumbone as determined by MTT assay. Data are presented as mean ± standard deviation (SD) from duplicate samples of at least three independent experiments
