Cancer stem cells (CSC) are emerging as key drivers of inter- and intratumoral heterogeneity. CSC have unique metabolic dependencies that are required not only for specific bioenergetic/biosynthetic demands but also for sustaining their operational epigenetic traits, i.e. self-renewal, tumor-initiation, and plasticity. Given that the metabolome is the final downstream product of all the -omic layers and, therefore, most representative of the biological phenotype, we here propose that a novel approach to better understand the complexity of tumor heterogeneity is by mapping and cataloging small numbers of CSC metabolomic phenotypes. The narrower metabolomic diversity of CSC states could be employed to reduce multidimensional tumor heterogeneity into dynamic models of fewer actionable sub-phenotypes. The identification of the driver nodes that are used differentially by CSC states to metabolically regulate self-renewal and tumor initation and escape chemotherapy might open new preventive and therapeutic avenues. The mapping of CSC metabolomic states could become a pioneering strategy to reduce the dimensionality of tumor heterogeneity and improve our ability to examine changes in tumor cell populations for cancer detection, prognosis, prediction/monitoring of therapy response, and detection of therapy resistance and recurrent disease. The identification of driver metabolites and metabolic nodes accounting for a large amount of variance within the CSC metabolomic sub-phenotypes might offer new unforeseen opportunities for reducing and exploiting tumor heterogeneity via metabolic targeting of CSC 2024-06-18T12:41:36Z 2024-06-18T12:41:36Z 2017-10-15 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion peer-reviewed http://hdl.handle.net/10256/20784 info:eu-repo/semantics/altIdentifier/doi/10.18632/oncotarget.21834 info:eu-repo/semantics/altIdentifier/eissn/ 1949-2553 Attribution 4.0 International (CC BY 4.0) https://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Impact Journals Oncotarget, 2017, vol. 8, núm. 59, p. 99223-99236 Articles publicats (IdIBGi) Cuyàs, Elisabet Verdura, Sara Fernández Arroyo, Salvador Bosch Barrera, Joaquim Martin Castillo, Begoña Joven, Jorge Menéndez Menéndez, Javier Abel 2017 Metabolomic mapping of cancer stem cells for reducing and exploiting tumor heterogeneity Oncotarget 8 59 99223 99236
