摘要
Objective:To investigate the effects of silencing BAK1 and BCL2 gene expression on proliferation,invasion and metastasis of hepatocellular carcinoma(HCC)HepG2 cells.Methods:30 HCC HepG2 cells were randomly divided into groups and received the corresponding treatments,namely,control group,NC-siRNA group,BAK1-siRNA group,BCL2-siRNA group and BAK1+BCL2 group,with 6 strains in each group.ThenqRT-PCR,CCK8,Transwell chamber invasion and scratch assay were used to detect the expression,proliferation,invasion and metastasis of BAK1 and BCL2 genes in HepG2 cells.Results:The mRNA expression,cell proliferation rate,cell migration rate and cell invasion ability of BAK1 and BCL2 in HepG2 cells were lowest in the BAK1+BCL2 siRNA group,followed by BCL2-siRNA group,BAK1-siRNA group,NC-shRNA group and control group(P<0.05).The proliferation rate of HepG2 cells in the BAK1+BCL2 siRNA group decreased significantly with time(P<0.05).Conclusion:Silencing the expression of BAK1 and BCL2 genes can inhibit the proliferation and invasion of HCC HepG2 cells and promote their apoptosis.
