ABSTRACT
OBJECTIVE@#To explore the effect of fluorouracil (FU) combined with epigenetic drug FK228 (depsipeptide FR901228) on the proliferation, apoptosis and Fas mRNA level in HepG2 hepatoma cell lines.@*METHODS@#There were 4 groups in this experiment an untreated group, an FK228 treated group, a FU treated group,and a FU combined with FK228 group.Tetrazolium salt colorimetry (MTT) assay was used to assess the cell inhibition rate. Q value of Kingos formula and multi-factor analysis of variance (ANOVA ) were used to judge the combination treatment effect,and flow cytometry was used to detect the apoptosis rate. Fas mRNA level was analyzed by RT-PCR.@*RESULTS@#FK228 or FU would inhibit the growth of HepG2 cells in a concentration-dependent and time-dependent manner. Cell inhibition rates of HepG2 were significantly enhanced in the FU combined with FK228 group, compared with that in the FU treated group alone (P<0.05). Both Q values were more than 1, the 2 drug combinations showed interaction,and FU combined with FK228 had synergistic effect.Compared with the FK228 treated group and the FU treated group, apoptosis rate of HepG2 cells was significantly increased (P<0.05), and the Fas mRNA level was up-regulated in HepG2 cells in FU combined FK228 group (P<0.05).@*CONCLUSION@#Combination of FK228 and FU can enhance the proliferation inhibition and apoptosis induction of FU in hepatoma cell lines, up-regulate the Fas mRNA level, and increase the sensitivity of hepatoma cell lines to FU.
