The intervention effects of naringin on oral squamous cell carcinoma cells
Objective:To investigate the effects of naringin(NRG)on apoptosis,proliferation,migration and invasion of oral squa-mous cell carcinoma(OSCC)cells.Methods:NRG of 0,5,10,15,20,25 and 30 μmol/L was respectively used to treat OSCC CAL-27 cells,and CCK-8 assay was used to cell vitality.CAL-27 cells were divided into low,medium and high dose NRG groups(NRG-L,NRG-M and NRG-H),Compound C(AMPK inhibitor)group,NRG-H+Compound C group,and control group(NC group,normal cul-ture).Cell proliferation,apoptosis,migration and invasion were detected by CCK-8 assay,EdU staining,flow cytometry,scratch and Tr-answell assays.The expression of aspartate specific cysteine proteinase-3(Caspase-3),proliferating cell nuclear antigen(PCNA),matrix metalloproteinase-2(MMP-2),MMP-9,p-AMPK,sirtuin 1(SIRT1)and acetylated NF-κB p65(Ac-NF-κB p65)was detected by Western blot.Results:5,10 and 20 µmol/L NRG was selected as the low,medium and high dose for the treatment of CAL-27 cells,re-spectively.Compared with NC group,in NRG-L,NRG-M and NRG-H groups EdU positive rate,scratch healing rate,A450 value,num-ber of invasive cells,the protein expression of PCNA,MMP-2,MMP-9 and Ac-NF-κB p65 in CAL-27 cells decreased,the apoptosis rate,and the protein of Caspase-3,p-AMPK,and SIRT1 increased(P＜0.05);in Compound C group EdU positive rate,scratch healing rate,A450 value,the number of invasive cells,the protein expression of PCNA,MMP-2,MMP-9 and Ac-NF-κB p65 in CAL-27 cells in-creased,apoptosis rate and the protein expression of Caspase-3,p-AMPK and SIRT1 decreased(P＜0.05).Compound C reversed the effects of high dose NRG on the proliferation,migration,apoptosis and invasion of CAL-27 cells.Conclusion:The inhibitory effects of NRG on proliferation,migration and invasion of CAL-27 cells and the promotion of apoptosis may be related to activation of AMPK and inhibition of NF-κB pathway.
