Objective To assess the drug sensitivity of pancreatic cancer cells based on real-time cell analysis and provide a reference for individualized diagnosis and treatment of pancreatic cancer.Methods Three human pancreatic cancer cells lines SW1900, Capan-2 and PANC-1 were selected and treated with gemcitabine hydrochloride and tegafur gimeracil oteracil potassium capsules, respectively. After 24 hours of culture, the cells were treated with the two drugs in gradient concentration. The cell growth curves before and after the drug administration was monitored using a real-time cells analyzer and the growth inhibition rates (IC50) of the drugs of the pancreatic cancer cells were calculated. At the same time, the cells in the cell culture plate were treated with the drug, and acridine orange/ethidium bromide (AO/EB) staining and laser scanning confocal microscopy were performed to observe the changes of cells after the drug administration. Results 72 hours after the drug administration, IC50 values for the three cell lines were different. The IC50 values of gemcitabine hydrochloride for SW1900, Capan-2 and PANC-1 cells were 1.69 μmol/L, 10.05 μmol/L and 12.74 μmol/L, respectively. The IC50 values of tegafur capsule for SW1900, Capan-2 and PANC-1 cells were 180.29 μmol/L, 765.70 μmol/L and 95.57μmol/L, respectively. AO/EB staining confirmed the reliability of IC50. Conclusions SW1900 and Capan-2 cells can be used as the control for gemcitabine hydrochloride and tegafur gimeracil oteracil potassium capsules to establish cell models for drug screening in vitro, which provides a reference for the application of the technology in anticancer drugs screening.
