Abstract

The effects of doxorubicin on the cellular biochemistry of the HeLa cell using 1H spin echo nuclear magnetic resonance spectroscopy (NMR) of the intact and viable cell in conjunction with dual wavelength HPLC of cell lysates is reported. Directly dose-related changes were observed in lactate and reduced glutathione concentration. Doxorubicin induces a time-dependent depletion of the cytosolic pool of glutathione and a change in the glycolytic pattern of the cell. The glutathione depletion could be partially reversed by controlled pre-treatment of the cells with N-acetylcysteine and cysteine, the protection being linked to the intracellular concentration of the thiol.

摘要

报道了使用完整活细胞的1H自旋回波核磁共振光谱(NMR)结合细胞裂解物的双波长高效液相色谱法(HPLC)研究阿霉素对HeLa细胞细胞生物化学的影响。观察到乳酸和还原型谷胱甘肽浓度与剂量直接相关的变化。阿霉素诱导细胞溶质谷胱甘肽池随时间的消耗以及细胞糖酵解模式的改变。用N-乙酰半胱氨酸和半胱氨酸对细胞进行可控预处理可部分逆转谷胱甘肽的消耗,这种保护作用与细胞内硫醇的浓度有关。
