Ferroptosis, a newly discovered form of non-apoptotic cell death, is induced by an excessive degree of iron-dependent lipid peroxide. ATPR, a novel all-trans retinoic acid (ATRA) derivative, has been extensively developed to show superior anticancer effect than ATRA in acute myeloid leukemia (AML). However, whether ferroptosis exists during ATPR treatment of AML remains unclear. Herein, we found that ferroptosis occurred in an AML xenograft mouse model of ATPR treatment. In vitro, ATPR was verified to induce ferroptosis in a dose-dependent manner by proferroptotic protein marker, lipid peroxidation, and lipid ROS, which could be significantly reversed by ferrostatin-1. Using lysosomal inhibitor chloroquine and iron chelator desferrioxamine, we further revealed that ATPR-induced ferroptosis was regulated by autophagy via iron homeostasis, especially Nrf2. Furthermore, targeting ferroptosis contributes to ATPR-induced AML differentiation. In conclusion, these results indicated that ferroptosis play an important role in ATPR-induced differentiation, and suggested that ATPR would provide a potential therapeutic value for AML treatment.Copyright © 2020.
