Despite increasing evidence on the formation of 1H NMR-detectable mobile lipid (ML) domains in cells induced to programmed cell death by continuous exposure to anticancer drugs, the time course of ML generation during the apoptotic cascade has not yet been fully elucidated. The present study shows that ML formation occurs at two different stages of(More)
K562 cells exposed for 3 h to taxol or taxol plus tyrphostin AG957 exhibited a significant variation in the concentration of the water-soluble metabolites glutathione, myo-inositol and phosphorylcholine, as evaluated by (1)H NMR up to 72 h incubation in drug-free medium. Cells treated with both drugs showed an increase of glutathione and glutathione(More)
