NMR peak ratios measured on K562wt and K562adr spectra. Cells were incubated for 2 hours in RPMI, or in RPMI containing methyl-β-cyclodextrin 5 mM (MCD). Results are expressed as means of arbitrary units ± SD multiplied by tenStatistical analysis : *: P < 0.05 when compared with RMPI incubated cells.
