The percentage of apoptotic PANC-1 and SW1990 cells was higher after PA-MSHA treatment compared to the controls (Figure 4). The rates of apoptosis were 8.17 ± 0.53% and 7.62 ± 0.89% in PANC-1 and SW1990 cells, respectively, after treatment with 0.25 × 109/mL PA-MSHA. These rates were much higher than those observed in the control group (4.18 ± 1.12% and 2.49 ± 0.74% for PANC-1 and SW1990 cells, respectively). Furthermore, the rate of apoptosis increased with increasing concentrations of PA-MSHA. Thus, our data demonstrate that PA-MSHA induces apoptosis in pancreatic cancer cell lines.
