Figure 4

Effect of PNA on cell viability. (a) A549 cells were treated with increasing concentrations of PNA (10–250 μM) for 48 hrs. Data are expressed as means ± s.d. of six values. (b) A549 cells were incubated for 48 hrs with 50 μM PNA. Where indicated, GGsToP (20 μM) was added to the incubation medium. Viability (b) and apoptosis index (Hoechst staining, (c) were then evaluated. Data are expressed as means ± s.d. of three to six values (b) or six values (c) and were analyzed by one-way ANOVA with Newman–Keuls test for multiple comparisons. (*)p < 0.0001 as compared to “Control”; (n.s.) not significant as compared with “PNA”.
