Effect of DFX on invasive ability of pancreatic cancer cells. a–c Pancreatic cancer cells were cultured in the upper chamber, and serum-free medium containing DFX (0, 10, 50, or 100 μM) was added to each chamber. After 96 h of incubation, a multimode reader was used to measure fluorescence at 480 nm/520 nm, which was then compared to that of the control group (n = 3). Data are presented as mean ± SD. *P < 0.05
