摘 要:目的观察组蛋白去乙酰化酶抑制剂MGCD0103对肝癌细胞BEL7402的生长抑制作用。方法加入不同浓度(0、0.1、1.0、5.0、10.0、50.0、100.0 μmol/L)的MGCD0103,运用细胞计数试剂盒(CCK-8)法检测其作用于BEL7402细胞24、48、72 h后细胞生长,计算存活率及半数抑制浓度。平板克隆形成实验检测MGCD0103作用于BEL7402细胞48 h后的克隆形成能力。细胞周期试剂盒检测MGCD0103作用于BEL7402细胞48 h后细胞周期分布的变化。细胞凋亡试剂盒检测MGCD0103作用于BEL7402细胞48 h后细胞凋亡率的变化。结果MGCD0103对BEL7402细胞具有生长抑制作用,呈剂量依赖关系,24、48、72 h半数抑制浓度分别为(19.36±2.13)、(9.12±0.87)及(4.95±0.45) μmol/L。MGCD0103减弱BEL7402细胞的克隆形成能力。MGCD0103影响BEL7402的细胞周期分布,引起G2/M期阻滞;药物处理后G2/M期细胞比例由(7.83±0.41)%增加至(15.84±1.69)%,差异有统计学意义(P=0.001)。MGCD0103可诱导BEL7402细胞凋亡;凋亡率由(6.23±0.66)%增加至(9.02±1.03)%(1 μmol/L)(P=0.017)、(15.93±1.77)%(5 μmol/L)(P=0.001)及(35.30±2.68)%(20 μmol/L)(P=0.000),差异有统计学意义。结论MGCD0103对肝癌细胞BEL7402具有生长抑制作用。ObjectiveTo investigate the effect of histone deacetylase inhibitor MGCD0103 on the growth inhibition of hepatocellular carcinoma cell line BEL7402.MethodsBEL7402 cells were treated with different concentrations (0, 0.1, 1.0, 5.0, 10.0, 50.0, 100.0 μmol/L) of MGCD0103 for 24, 48, or 72 h and their growth was tested by cell counting kit-8 (CCK-8) assay. Cell viability and half maximal inhibitory concentration were then calculated. Cell tumorigenicity of BEL7402 cells treated with MGCD0103 for 48 h was tested using colony formation assay. The distribution of cell cycle and the apoptosis rate of BEL7402 cells treated with MGCD0103 for 48 h were analyzed by flow cytometry.ResultsMGCD0103 inhibited the growth of BEL7402 cells in a dase-dependent manner. The half maximal inhibitory concentrations for MGCD0103 at 24, 48, and 72 h were (19.36±2.13), (9.12±0.87) and (4.95±0.45) μmol/L respectively. MGCD0103 attenuated cell tumorigenicity of BEL7402 cells. MGCD0103 influenced the cell cycle distribution of BEL7402 cells and caused G2/M phase arrest. After treatment, the proportion of G2/M phase cells was increased from (7.83±0.41)% to (15.84±1.69)% (P=0.001). MGCD0103 triggered apoptosis of BEL7402 cells. The apoptosis rate was (6.23±0.66)% (control group), (9.02±1.03)% (1 μmol/L) (P=0.017), (15.93±1.77)% (5 μmol/L) (P=0.001), and (35.30±2.68)% (20 μmol/L) (P=0.000), respectively.ConclusionMGCD0103 has inhibitory effect on the growth of BEL7402 cells.
