摘要:

运用核磁共振波谱(NMR)研究三尖杉酯碱(HT)诱导人早幼粒白血病细胞(HL-60)凋亡中三磷酸腺苷(ATP)、磷酸单脂(PME)及脂类的代谢变化. 经HT作用2 h后,从31P NMR中发现HL-60细胞中ATP、PME含量减少;而在1H NMR中甲基 峰有明显的增强,胆碱峰稍微减弱. 这些现象的研究将有利于增进对细胞凋亡发生机制的认识.

Abstract:

NMR spectroscopy methods were used to study the metabolic changes of A TP, PME and lipid during harringtonine (HT) induced apoptosis in HL-60 cell. After HL-60 cells were treated with HT for two hours, it was observed by 31P-NMR sp ectroscopy that the levels of ATP and PME decreased significantly and intracellu lar pH increased significantly. It was also found by 1H-NMR a significa nt increa se in the signal intensity of methylene resonance and a slight decrease in choli ne peak in treated HL-60 cells. The present investigation will be helpful for  understanding the mechanism of Harringtonine induced apoptosis in HL-60 cells.

Key words: NMR, spectroscopy, HL-60, harringtonine (HT)
