Curcumin elicits G2/M phase arrest. A. Cell cycle profiles of curcumin-incubated DAOY cells as analyzed by flow cytometry. Cells were exposed to curcumin at the indicated concentrations for 7 hours (top) and 24 hours (bottom). Note the increase in cells arrested in G2/M upon curcumin treatment. B. Quantitative analysis of cells in A obtained from three independent experiments. Averages of mean ± SD are shown.
