Figure 3. Effects of NaP combined with cisplatin on apoptotic rate of HCC cell lines.

(A–D) HCC cells were treated with cisplatin (25 µM), NaP (1 mM), or both agents for 48 h. Cells were then stained with annexin V and PI, followed by cytometry analysis. Data are shown as mean ± SD of % apoptosis from three independent experiments. ^*P < 0.05, ^**P < 0.01 by one-way ANOVA with a Scheffe post hoc test.
