AXPare the first decreased for the induced and and confirmed that GSH, Tau, AXP, and Lac levels principal contributors to distinguishing samples depending on resistance, whereas PCwas only aor no impact on and substantially rose at cisPt concentrations of 8 .

Creatine (Cre) levels two.4. Evaluation of Single Metabolites were strongly reduced down to 20 and 40 in induced and de-induced cells, respectively, compared to controls. The metabolite levels primarily marking resistance are plotted relative to controls as a function of cisPt concentration for the samples with induced (purple symbols) and de2.5. Metabolic Alterations Induced resistance in Figure induced (orange symbols) cisPt by cisPt Resistance six. Again, in these single metabolite The becomes from the metabolic profile from cisPt sensitive cells increases using the congraphs, itdeviation evident that the metabolite concentrations are, all through all samples, centration of cisPt exposure and most de-induced the resistance.
