FIGURE 3. Effects of IFN-α (A–C) and IFN-β (D–F) on the apoptosis (DNA fragmentation) in BxPC-3, MiaPaCa-2, and Panc-1 cell lines. Pancreatic cancer cell lines were incubated for 3 days without (control) or with the drugs indicated at different concentrations. Values are absorbance units and are expressed as percent of the control. Data are the mean ± SEM. *P < 0.001; **P < 0.01.
