Histograms for cell cycle analysis by flow cytometry on MCF-7 cells. Treatment were 28 µM E (A), DMSO (B) 1.3 µM TMX (C), ethanol (D) or non-exposed cultures (E). a, b and c represent cells in Go/G1, S and G2M, respectively and FL3 represents the popidium iodide fluorescence. Letter a corresponds to Go, b to S and c to G2M phases of the cell cycle. This figure is representative of two independent experiments and it shows that solvent treated cells behave like cells grown in cell culture as opposed to EP and TXM exposed cells that exhibit cell cycle arrest
