ABSTRACT = {This study was directed to deepen the effects of nutrient shortage on BCR/Ablprotein expression and signaling in 
chronic myeloid leukemia (CML) cells. The backbone of the study was cell culture in medium lacking glucose, 
the consumption of which we had previously shown to drive BCR/Ablprotein suppression, and glutamine, the 
other main nutrient besides glucose. In this context, we focused on the role of lactate, the main by-product of 
glucose metabolism under conditions of rapid cell growth, in particular as a modulator of the maintenance of 
CML stem/progenitor cell potential, a crucial determinant of disease course and relapse of disease. The results 
obtained indicated that lactate is a powerful surrogate of glucose to prevent the suppression of BCR/Abl signaling and is therefore capable to maintain BCR/Abl-dependent CML stem/progenitor cell potential. A number of 
metabolism-related functional and phenotypical features of CML cells were also determined. Among these, we 
focused on the effect of lactate on oxygen consumption rate, the dependence of this effect on the cell surface 
lactate carrier MCT-1, and the relationship of the lactate effect to pyruvate and to the activity of mitochondrial 
pyruvate carrier.},
