Right here, we use LC/MS/MS metabolomics (200 metabolites) to assess metabolic changes induced by metformin and phenformin in an Srcinducible model of cellular transformation and in mammospherederived breast CSCs. While phenformin will be the extra potent biguanide in each systems, the metabolic profiles of those drugs are remarkably similar, although not identical. In the course of the procedure of cellular transformation, biguanide treatment prevents the enhance in glycolytic intermediates at a precise stage of your pathway and coordinately decreases tricarboxylic acid (TCA) cycle intermediates. In contrast, in breast CSCs, biguanides possess a modest effect on glycolytic and TCA cycle intermediates, however they strongly deplete nucleotide triphosphates and may well impede nucleotide synthesis. These metabolic profiles are constant with all the idea that biguanides inhibit mitochondrial complex 1, however they indicate that their metabolic effects differ based on the stage of cellular transformation.glycolysis| metabolism | cancer metabolism | metabolic profilingltered metabolism can be a hallmark of malignantly transformed cells.
