High mtDNA content identifies oxidative phosphorylation-driven acute myeloid leukemias and represents a therapeutic vulnerability

production, a resistance mechanism that could be bypassed by targeting the nicotinamide phosphoribosyltransferase (NAMPT) enzyme. In summary, we demonstrated that mtDNAc is an effective tool for assessing the metabolic state of AML cells. This method can be easily implemented in clinical practice to identify chemoresistant patients and guide personalized treatment strategies, including novel combination therapies for those with a high reliance on mitochondrial metabolism.
