Aurora蛋白激酶抑制剂VX-680对人肝癌细胞HepG2细胞间同质黏附力和迁移能力的影响

目的:研究Aurora蛋白激酶抑制剂VX-680对人肝癌细胞HepG2细胞间同质黏附力和迁移能力的影响。方法:分别设立实验组和对照组:实验组加VX-680,总共设置3个浓度组(3.125μmol/L组、6.25μmol/L组和12.5μmol/L组);对照组加DMSO。采用细胞缓慢聚集实验和分离实验观察不同浓度VX-680对HepG2细胞间黏附能力的影响。通过划痕愈合实验检测不同浓度VX-680对Hep G2细胞迁移能力的影响。Western blot检测HepG2细胞E-钙黏蛋白(E-cadherin)的表达。结果 :细胞缓慢聚集实验结果显示,相比对照组,各实验组细胞所形成的细胞团块数均明显减少(P0.01)。细胞分离实验结果显示,随着VX-680浓度的升高,N_(TC)/N_(TE)的比值逐渐降低,即细胞间黏附能力逐渐增强。划痕愈合实验结果显示,相比对照组,随着VX-680浓度的升高,细胞划痕愈合能力逐渐减弱。Western blot实验结果显示HepG2细胞中E-cadherin的表达随着VX-680浓度的升高而增加(P0.05)。结论 :VX-680可以增加人肝癌细胞HepG2细胞间的同质黏附力,同时抑制其迁移。

Effect of Aurora protein kinase inhibitor VX-680 on homogeneity adhesion and migration in human hepatoma HepG2 cell

AIM:To study the effect of Aurora protein kinase inhibitor VX-680 on homogeneous adhesion and migration ability in human hepatocellular carcinoma cell line HepG2. METHODS:The HepG2 cell were divided into experimental group and control group, respectively. VX-680 was used in experimental groups at 3 concentrations (3.125 μmol/L group, 6.25 μmol/L group and 12.5 μmol/L group). DMSO was used in the control group. The effects of VX-680 at different concentrations on the adhesion ability of human hepatocellular carcinoma HepG2 cells were observed by cell slow aggregation test and separation experiment. The effects of VX-680 at different concentrations on the migration ability of HepG2 cells was detected by wound healing assay. The expression of E-cadherin in HepG2 cells was detected by Western blot. RESULTS:The results of the slow aggregation test showed that compared with the control group, the number of cell clumps formed in experimental groups was significantly decreased (P<0.01). The results of separation experiment showed that the ratio of N_TC/N_TE gradually decreased with the increased concentration of VX-680. The results of wound healing assay showed that as the concentration of VX-680 increased, the cell scratch healing ability gradually weakened compared with control group. The results of Western blot showed that the protein expression of E-cadherin in the HepG2 cells increased with the increased concentration of VX-680 (P<0.05). CONCLUSION:VX-680 increases the homogeneous adhesion and inhibits the migration of HepG2 cells.
