Effects of resveratrol (RES) and piceid (PD) on cell cycle of MDA-MB-231 cells, MCF-7 cells and HepG2 cells.

<p>Cultures of MDA-MB-231 cells were treated with varying concentrations of resveratrol and piceid for 24 h. At the end of treatment, cells were trypsinized, incubated with RNase, stained with propidium iodide (PI), and analyzed by flow cytometry. Results shown are of an experiment representative of cell cycle.
