The effect of rapamycin on Skp2 protein levels and cell cycle distribution. (a) The effect of rapamycin on Skp2 protein levels. The breast cancer cell lines T47D and MDA-MB-231 were treated with rapamycin (20 nM) for different time periods and the expression of the protein was determined by western blot analysis. Skp1 was used as a loading control. (b) The time-dependent effect of rapamycin on G1 distribution in T47D and MDA-MB-231 cells. Cells were treated with rapamycin (20 nM) for different time periods and the percentage of cells in G1 was determined by FACS analysis using Modfit LT 2.0 software.
