Abstract: OBJECTIVE: To investigate the effects of total saponins from the seeds of Nigella glandulifera Freyn (TSNG) on proliferation,migration,apoptosis and autophagy of SiHa cells. METHODS: SiHa cells were divided into untreated control group,TSNG (0.8,0.9,1.0,1.1,1.2,1.4,1.6,1.8 mg/mL) treatment group and HCQ (10 μmol/L) intervention group. Growth inhibition was detected by using the MTT assay. Anti-migration effects were detected by the cell scratch assay. Apoptosis rates were determined using the flow cytometry assay with Annexin V-FITC/PI staining. Nuclear apoptosis was observed after Hoechst staining. The formation of autophagosomes was detected after MDC staining. Protein expressions of LC3-Ⅱ and p62 were detected by Western blotting. RESULTS: Compared with the control group,TSNG had an inhibitory effect on cell growth which shows a dose-dependent effect relationship (P<0.05 or 0.01). The relative migration rates from the 0.9,1.0,1.1mg/mL TSNG treatment groups were (20.40±2.49)%,(15.14±0.39)% and (5.05±1.04)%,which were lower than those of the control group (36.63±2.52)% (P<0.01). The apoptosis rates from the 1.0,1.2,1.4 mg/mL TSNG treatment groups were (39.10±0.22)%,(68.37±0.58)% and (80.93±0.12)%,respectively,which were higher than those of the control group (10.73±0.82)% (P<0.05 or 0.01). Compared with the control group,the cell nuclei from thef TSNG treated group showed more apoptotic changes, increased autophagosomes,and increased the LC3-Ⅱ and p62 protein expressions (P<0.05 or 0.01). Compared with the TSNG treatment group,LC3-Ⅱ protein expressions had no significant changes after HCQ pretreatment. CONCLUSION: TSNG exposure caused inhibition of proliferation and of migration,induced apoptosis and blocked autophagy in SiHa cells.
