PML::RARα+ myeloid cells display metabolic alterations that can be targeted to treat resistant/relapse acute promyelocytic leukemias.

ABSTRACT: At present there is no metabolic characterization of acute promyelocytic leukemia (APL). Pathognomonic of APL, PML::RARα fusion protein rewires metabolic pathways to feed anabolic tumor cell's growth. All-trans retinoic acid (ATRA) and arsenic trioxide (ATO)-based therapies render APL the most curable subtype of AML, yet approximately 1% of cases are resistant and 5% relapse. We characterized the metabolic peculiarity and fuel requirement of PML::RARα expressing cells, to identify new targets for tailored therapies in resistant or relapsed APL patients. We analyzed cell metabolism in primary samples from seven APL patients, comparing them with normal CD34+ cells differentiated to promyelocyte and granulocyte, and different PML::RARα expressing cell lines. We show that the PML::RARα oncopro
