Elevated Lactate In Aml Bone Marrow Contributes To Macrophage Polarization Via Gpr81 Signaling., Celia A Soto, Maggie L Lesch, Jennifer L Becker, Azmeer Sharipol, Amal Khan, Xenia L Schafer, Zhewen Li, Amanda R Streeter, Michael W Becker, Joshua C Munger, Benjamin J Frisch

Oncology Articles

Interactions between acute myeloid leukemia (AML) and the bone marrow microenvironment (BMME) are critical to leukemia progression and chemoresistance. In the solid tumor microenvironment, altered metabolite levels contribute to cancer progression. We performed a metabolomic analysis of AML patient bone marrow serum, revealing increased metabolites compared to age- and sex-matched controls. The most highly elevated metabolite in the AML BMME was lactate. Lactate signaling in solid tumors induces immunosuppressive tumor-associated macrophages and correlates with poor prognosis. This has not yet been studied in the leukemic BMME. Herein, we describe the role of lactate in the polarization of leukemia-associated macrophages (LAMs). …
