Figure 4From: Polysaccharopeptides derived from Coriolus versicolor potentiate the S-phase specific cytotoxicity of Camptothecin (CPT) on human leukemia HL-60 cellsEffect of PSP on HL-60 cell cycle distribution. HL-60 cells were treated with PSP (25 μg/ml) for 72 hours. Cell cycle distribution in G0/G1, S and G2/M phases was measured by DNA/PI flow cytometry. Values are expressed as mean (SD) (n = 5). * P < 0.001, vs. control.Back to article page
