摘要: 为探讨蜂胶黄酮Pinobanksin-3-acetate(PB3A)对人肝癌HepG-2和肝正常细胞L02增殖、形态学变化和细胞凋亡的影响,采用MTT显色法检测不同浓度PB3A作用不同时间对SGC-7901细胞生长所产生的影响,计算生长抑制率和IC50值;倒置显微镜观察PB3A干预后细胞的形态学变化;Annexin V-FITC/PI双染色、流式细胞仪检测细胞的凋亡率;结果显示,PB3A可显著抑制HepG-2和L02细胞的增殖,并呈浓度和时间依赖性,各时间段HepG-2细胞IC50值明显低于L02细胞。流式细胞检测结果显示,PB3A能促进HepG-2和L02细胞凋亡,并呈剂量依赖性,同浓度PB3A诱导HepG-2细胞的早期凋亡率明显高于L02细胞。上述结果表明,PB3A对人正常肝L02细胞和肝癌HepG-2具有明显的区别增殖抑制和诱导凋亡作用,区别抑制作用的本质是PB3A诱导两种细胞凋亡的程度不同。

Abstract: The purpose of this study was to evaluate the anticancer activity of pinobanksin-3-acetate (PB3A) on human hepatoma cell line HepG-2 and normal hepatocyte cell line L02.The effect of different concentrations of PB3A for different durations on the proliferation of the cell line HepG-2 and L02 were analyzed by MTT assay.The morphological changes of HepG-2 and L02 cells were observed by the inverted photo microscopy after treatment with different concentrations of PB3A for different durations.The apoptotic rate was measured by flow cytometry.MTT assay showed that PB3A inhibited the growth of HepG-2 and L02 cells in a dose and time dependent manner,in the same incubation time,the IC50 values of HepG-2 cells were lower than L02 cells.FCM results indicated that PB3A induced the apoptosis of HepG-2 cells and L02 cells in a dose-depended manner.In the same concentration of PB3A,the early apoptotic rate of HepG-2 cells was higher than L02 cells.In conclusion,PB3A can inhibit human hepatoma HepG-2 cells and hepatocyte L02 cells through induction of apoptosis.Higher sensitivity to PB3A were found in HepG-2 cells than L02 cells.

Key words: PB3A, HepG-2 and L02, proliferation, apoptosis
