Abstract:
Objective:To investigate the effects of poly adenosine diphosphate ribose polymerase-1(PARP-1) inhibitor fluzoparib on proliferation, apoptosis and migration of pancreatic cancer PANC1 cells.Methods:PANC1 cells cultured in conventional culture medium were used as control group, and PANC1 cells cultured in the medium containing fluzoparib were used as fluzoparib group. The effects of fluzoparib with different concentrations on the proliferation of PANC1 cells were detected by CCK8 method, and the half inhibitory concentration (IC 50) of fluzoparib on PANC1 cells was calculated. The effect of fluzoparib on apoptosis and cell cycle of PANC1 cells was detected by flow cytometry, and the migration ability of PANC1 cells was detected by cell scratch test and Transwell chamber. Results:Compared with control group, with the increase of fluzoparib concentration and the prolongation of the action time, the cell proliferation activity of PANC1 in fluzoparib group was significantly decreased, and the differences were statistically significant (all P values <0.05). IC 50 of fluzoparib on PANC1 cells cultured for 24 h was 0.03 mmol/L. After 24 h culture, the IC 50 apoptosis rate of fluzoparib group was (32.19±2.48)%, and the apoptosis rate of control group was (21.99±6.30)%. The former was greatly higher than the latter, and the difference was statistically significant ( P<0.05). The proportion of cells in G 2/M phase was (16.28±0.62)% in the fluzoparib group and (11.64±0.88)% in the control group, and the difference between the two groups was statistically significant ( P<0.05). The migration rates of PANC1 cells in IC 50 fluzoparib group in 12 h and 24 h culture were (2.59±1.46)% and (19.76±7.84)%; and those in control group were (27.08±2.17)% and (45.92±3.61)%, respectively. The number of transmembrane cells was (348±19) cells/10 visual field in the fluzoparib group and (587±14) cells/10 visual field in the control group. The migration ability of PANC1 cells in fluzoparib group was significantly lower than that in control group ( P<0.05). Conclusions:Fluzoparib can inhibit the proliferation and migration of PANC1 cells and promote the apoptosis of PANC1 in vitro, which may be an effective drug for the treatment of pancreatic cancer.
