Figure 2From: Polyamine depletion induces G1 and S phase arrest in human retinoblastoma Y79 cellsEffects of DFMO on Y79 cell cycle. Y79 cells were treated with 5 mM DFMO for 24, 48, and 72 h. Cell cycle was analyzed using a flow cytometer (A), as described under Experimental Procedures, and percentages of G1, S, and G2 phase cells are shown (B).
