Rsv abrogates TMZ-induced arrest in G2/Min U251 cells, while U138 is resistant to TMZ-induced arrest. Cell cycle distribution of U251 and U138 cells treated with Rsv 30 μM, TMZ 100 μM or RT, for 48 h. Representatives histograms are shown on the top of figure of flow cytometry; numbers between the lines indicates the percentage of cells in each phase of cell cycle, as indicated; cells were treated as cited above, followed by fixation as described on material and methods section, staining with 6 μM PI and flow cytometry to determination of DNA content; * p<0.05; ** p<0.01.
