Abstract:Objective To investigate the effect of nitidine chloride on cell proliferation, apoptosis, invasion and migration in laryngeal carcinoma cell Hep-2 in vitro. Methods Hep-2 cells were cultured by nitidine chloride with 5, 10, 20, 40, 60, 80 μmol/L in vitro, and MTT was performed to observe the proliferation at different times. Annexin V-FITC/PI flow cytometry was used to determine the apoptosis rate by nitidine chloride with 10, 20, 40 μmol/L. Transwell method was used to detect the invasion and migration by nitidine chloride with 5, 10 μmol/L. Results At concent of 5, 10, 20, 40, 60, 80 μmol/L, the growth inhibition rate of nitidine chloride on Hep-2 cells increased gradually with the increase of time, compared with the control group at the same time point (P < 0.05). At concent of 10, 20, 40 μmol/L, the apoptosis rate of Hep-2 cells induced by nitidine chloride gradually increased, compared with the control group, the differences were statistically significant (P < 0.05); compared with the nitidine chloride with 10 μmol/L, the nitidine chloride with 20, 40 μmol/L increased the apoptosis rate, the differences were statistically significant (P < 0.05). Compared to the control group, nitidine chloride with 5, 10 μmol/L reduced the number of cells of invasion and migration of Hep-2 cells significantly (P < 0.05); compared with the nitidine chloride with 5 μmol/L, nitidine chloride with 10 μmol/L decreased the number more significantly (P < 0.05). Conclusion Nitidine chloride could inhibit the proliferation of Hep-2 cells, the mechanism is related to the induction of apoptosis and the inhibition of invasion and migration.
