Objective : We investigated the effects on the cell cycle and p53 expression by the treatment of various concentrations of staurosporine to elucidate the molecular mechanism of staurosporine induced cell cycle arrest in MCF-7 cell line. Methods : Various concentrations of staurosporine were treated in MCF-7 cells cultured with RPMI 1640 media. The harvested cells were fixed and permeabilized with 1% paraformaldehyde and absolute methanol. Then the cells were stained indirectly with anti-p53 primary antibody and FITC conjugated goat anti-mouse(GAM)-IgG secondary antibody. Sequentially DNA were stained with 0.1% RNase and PI solution. These stained cells were analyzed by the standard FACScan flow cytometer. The obtained results were analyzed further with WinList 3.0, and ModiFit LT software program. Results : MCF-7 cells were arrested mostly in G1 phase of cell cycle at 5-10 nM of staurosporine, however, the cells were arrested in G2 phase at 20-100 nM of staurosporine. The expressions of p53 protein were higher in the MCF-7 cells treated with both concentrations of 10 nM and 100 nM of staurosporine compaired with the control cells. This suggests that the p53 may be involved in the mechanism of G1 and G2M arrest of cell cycle in MCF-7 cell. Conclusion : The points of arrest in cell cycle differred depending on the concentrations of staurosporine and these cell cycle arrests at G0G1 and G2M pahse were related with p53 protein expression. It suggested that these results could be extended to study for staurosporine to be usefull as a potential anti-tumor agent.
