摘要: 目的: 观察白藜芦醇的修饰物白藜芦醇烟酸 酯(ResT) 对人肝癌细胞HepG2 生长增殖的影响及诱 导凋亡的作用。 方法: 用不同浓度的 ResT 处理 HepG2 细胞,MTT 法检测 ResT 对HepG2 细胞生长增 殖的抑制作用;应用 Hochest 荧光染色法观察凋亡细 胞的发生;流式细胞术(FCM) 检测分析细胞周期和 细胞凋亡率;比色法测定 Caspase-3 酶活性。结果: ResT 抑制 HepG2 细胞的增殖并呈现一定的量效和 时效关系, HepG2 细胞与 ResT 作用后出现典型的凋 亡细胞形态改变, FCM 分析显示大部分细胞阻滞于 G1 期, S 期细胞比例降低。且药物作用组出现凋亡 峰。药物作用 12、24、48 h 后, 细胞的凋亡率分别为 8.7 %、21.1%、和 32.7 %。显示 ResT 诱导的细胞凋 亡作用随时间的延长而增加, 同时Caspase-3 酶活性 显著增强。 结论: ResT 可抑制人肝癌细胞 HepG2 的 生长增殖, 其作用机制之一可能与阻滞细胞于 G1 期 及诱导细胞凋亡有关。

Abstract: AIM: To study the effects of resveratrol trinocotinate(ResT), a structure modification compound on the basis of resveratrol, on proliferation inhibition and apoptosis in HepG2 cell line.METHODS: HepG2 cell were cultivated with different concentration of ResT at the different time in vitro.The proliferation inhibition was measured by MTT assay.Hochest staining method was used to determine the apoptosis, and then FCM was used to analyzed the cell cycle distribution and apoptosis rate, Colorimetric assay wasemployed to detect the activation of Caspase-3.RESULTS: ResT caused growth inhibition in a time and dose-dependent manner.After treatment with ResT for 24 h, some cells appeared apoptotic characteris-tics.The flow cytometric profiles revealed that ResT in-duced cell into G1 -phase and cells in S-phase were de-creased, Apoptotic peaks were observed in the cell cycle analysis.The apoptosis rates were 8.7%, 21.1% and 32.7% respectively after treatment for 12, 24, 48 h. Caspase-3was also activated.CONCLUSION: Induction of apoptosis and G1 -phase cell cycle arrest may be respon-sible for the growth inhibition effect of ResT in HepG2 cell.
