甘草查尔酮A通过PI3K/Akt信号通路对胶质瘤U87细胞增殖、迁移、侵袭和氧化损伤的影响
Effects of Licorice chalcone A on proliferation,migration,invasion and oxidative damage of glioma U87 cells through PI3K/Akt signaling pathway
摘要
Abstract
Objective To investigate the effects of Licorice chalcone A(LCA)on proliferation,migration,invasion and antioxidant capacity of human glioma U87 cells and its mechanism.Methods Glioma U87 cells cultured in vitro were divided into 4 groups,blank control group(conventional culture)and experimental-L,-M,-H groups(5,10,20 μmol·L-1 LC A).Cell proliferation capacity was detected by cell counting kit-8,cell clonogenesis ability was detected by clonogenesis assay,cell migration ability was detected by scratch assay,and cell invasion ability was detected by Transwell assay.Colorimetric assay was used to detect total glutathione(T-GSH),malondialdehyde(MDA)and superoxide dismutase(SOD),and Western blotting was used to detect the protein expression levels of phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt).Results The cell proliferation activities of blank control group and experimental-L,-M,-H groups were(90.20±2.17)％,(79.06±1.57)％,(66.13±2.11)％and(49.52±1.82)％;cell clone formation rates were(76.83±2.30)％,(42.33±2.09)％,(17.71±1.84)％and(12.12±1.97)％;12 h cell mobility rates were(34.92±2.24)％,(27.90±1.89)％,(18.76±1.14)％and(14.87±0.82)％;24 h cell mobility rates were(50.37±2.61)％,(39.43±2.56)％,(21.11±2.33)％and(18.32±2.39)％;the number of perforated cells were 120.39±4.16,79.95±3.83,45.67±3.55 and 18.14±2.85;T-GSH levels were(71.43±2.39),(58.51±2.91),(49.43±2.78)and(35.44±2.76)μmol·L-1;MDA levels were(4.14±0.91),(7.23±1.75),(9.20±1.56)and(11.37±1.90)nmol·mL-1;SOD levels were(41.44±2.10),(35.43±2.91),(28.56±2.32)and(20.62±2.05)U·mg-1;the relative expression levels of p-Akt were 1.27±0.03,1.06±0.02,0.89±0.01 and 0.60±0.02,respectively.The above indexes were statistically significant between experimental-L,-M,-H groups and blank control group(all P＜0.01).Conclusion LCA can inhibit the proliferation,migration,invasion and induce oxidative damage of glioma U87 cells,and its mechanism may be related to the down-regulation of p-Akt protein expression in PI3K/Akt signaling pathway.关键词
