Comparison of the effects of flavone A and flavone B on breast cancer MCF7 and SK-BR3 cells.

<p>The effects of flavone A and flavone B on the more differentiated breast cancer MCF7 (A), and the poorly differentiated breast cancer Sk-BR3 cells (B) were determined by MTT assay and are represented as a percent of the control absorbance at a wavelength of 570 nm. All data were collected at 24 h after treatment. Data shown are from representative experiments (mean ± SE, n = 3). * p<0.05, significant difference between control and other concentrations for each flavone. # p<0.05, significant difference between flavone A and flavone B treated cells at similar concentrations. C. Half maximal effective concentration (EC₅₀) ± SE for flavone A and flavone B treatment on MCF7 and SK-BR3 cells. The values were estimated by non-linear regression analysis.
