Abstract
Mitochondrial metabolic dependencies characteristic of acute myeloid leukemia (AML) have recently been identified, demonstrating that metabolic enzymes regulate AML gene expression and control cell differentiation and stemness. These mitochondrial metabolic adaptations occur independently of underlying genomic abnormalities and contribute to chemotherapy resistance and relapse. Mitochondrial alterations also lead to metabolic vulnerability of AML cells, whose metabolism is characterized by dependence on oxidative phosphorylation, fatty acid oxidation, reactive oxygen species (ROS) production, and mitochondrial dynamics. Currently, mitochondrial properties of AML cells and leukemia stem cells are being investigated, focusing on metabolism, signal transduction, mitochondrial respiration, ROS generation, and mitophagy. In addition, mitochondria-targeted agents have shown promising results in clinical trials. This paper outlines recent findings from preclinical and clinical trials on the utility of agents targeting mitochondria-related molecules and metabolic pathways and their efficacy in combination with existing chemotherapies.
