Objective To observe the effects of matrine on the proliferation,migration,and invasion of human neuroblastoma cells,and to investigate its potential mechanism.Methods This study was divided into AS experimental group(SK-N-AS cells treated with IC50 concentration of matrine),AS blank group(SK-N-AS cells cultured under normal conditions),AS control group(SK-N-AS cells treated with an equal amount of dimethyl sulfoxide),DZ experimental group(SK-N-DZ cells treated with IC50 concentration of matrine),DZ blank group(SK-N-DZ cells cultured under normal conditions),and DZ control group(SK-N-DZ cells treated with an equal amount of dimethyl sulfoxide).Scratch assay and Transwell chamber were used to measure the effect of matrine on the migration and invasion.The expression of E-cadherin,N-cadherin and Vimentin were tested by Western blot.Results After different intervention,the migration percentages of AS blank group,AS control group,AS experimental group,DZ blank group,DZ control group and DZ experimental group were(66.32±3.12)％,(65.27±3.44)％,(23.73±0.79)％,(46.25±4.68)％,(44.15±5.60)％and(16.77±3.52)％,respectively;the number of invasive cells were 870.45±19.32,865.32±23.39,492.74±16.81,1 198.10±43.71,1 203.03±71.91 and 891.69±42.62,respectively;the expression levels of E-cadherin protein were(100.00±11.72)％,(105.65±13.11)％,(477.20±29.71)％,(100.00±12.54)％,(97.78±12.77)％and(240.53±12.23)％,respectively;the expression levels of N-cadherin protein were(100.00±15.44)％,(103.90±10.76)％,(43.52±9.96)％,(100.00±10.12)％,(104.95±10.49)％and(38.39±8.70)％,respectively;Vimentin protein expression levels were(100.00±9.51)％,(97.39±11.33)％,(59.13±10.25)％,(100.00±13.20)％,(96.27±11.01)％and(47.67±9.48)％,respectively.There were statistically significant differences in the above indexes between the AS group and the AS blank group(P＜0.01,P＜0.001),and there were statistically significant differences between the above indexes in the DZ group and the DZ blank group(P＜0.01,P＜0.001).Conclusion Matrine inhibits the proliferation,migration,and invasion of neuroblastoma SK-N-AS and SK-N-DZ cells,potentially through suppressing epithelial-mesenchymal transition.
