Figure 1

Coffee extract effect on cell cancer viability. Human cancer cell lines (MCF7 and MDA-MB-231) and human epithelial breast cell lines (MCF 10A) were treated for 24 h with increasing concentrations of (a) green coffee or (b) dark coffee (0-5000 μg/mL). (c) Inhibitory concentration 50% (IC50) on breast cell line treated with green and dark coffee was determined and expressed as μg/mL. represents statistically significant difference in the column indicated with respect to treated MCF 10A, as determined by ANOVA (), with Tukey’s multiple comparison posttest. (d) Cell morphology was analyzed by light microscopy. . Values are represented as from three independent experiments.
