N-methyladenosine (mA) is a common chemical modification for mammalian mRNA and exhibits high dynamics in various biological processes. However, dynamics of mA RNA methylome during leukemogenesis remains unknown. Here, we delineate a comprehensive mA landscape during acute myeloid leukemia (AML) development and identify PRMT6 as a key for maintaining AML stem cells. We observe an obvious change in mA methylome during leukemogenesis and find that protein arginine methyltransferase PRMT6 and mA reader IGF2BP2 maintain the function of human and murine leukemia stem cells (LSCs). Genetic deletion or pharmacological inhibition of PRMT6 damages AML development and LSC function. Mechanistically, IGF2BP2 stabilizes PRMT6 mRNA via mA-mediated manner, which catalyzes H3R2me2a and suppresses lipid transporter MFSD2A expression. PRMT6 loss upregulates MFSD2A expression that increases docosahexaenoic acid levels and impairs LSC maintenance. Collectively, our findings reveal a critical role of PRMT6-MFSD2A signaling axis in AML development and provide a therapeutic strategy for targeting LSCs.

Introduction: Acute myeloid leukemia (AML) patients are highly susceptible to infection. Moreover, prophylactic and empirical antibiotic treatment during chemotherapy disrupts the gut microbiome, raising the risk for antibiotic-resistant (AR) opportunistic pathogens. There is limited data on risk factors for AR infections or colonization events in treated cancer patients, and no predictive models exist.

Background: Acute myeloid leukemia (AML) involves uncontrolled proliferation of myeloid progenitor cells and carries a poor prognosis. The PI3K/AKT/mTOR pathway plays a key role in AML pathogenesis by regulating cancer cell proliferation and survival. This study investigates the effects of inhibiting the PI3K/AKT/mTOR pathway on autophagy in AML cell lines, aiming to support targeted therapy development that modulates autophagy.

Acute myeloid leukemia (AML) represents a genetically heterogeneous malignancy, with mutations in the nucleophosmin-1 (NPM1) gene identified as the most prevalent and clinically significant molecular biomarkers. These mutations play a crucial pivotal role in the realms of diagnosis, prognosis, and therapeutic decision-making. Although an ideal measurable residual disease (MRD) test has yet to be developed, there is increasing acknowledgment of the significance of advanced molecular methodologies for monitoring MRD in NPM1-mutated (NPM1) AML.

Purpose Of Review: Acute myeloid leukemia (AML) is a biologically diverse disease that has undergone significant transformation in recent years. The rapid pace of discovery in molecular genetics, disease classification, and therapeutic development has reshaped how we approach diagnosis and treatment. This review aims to provide a timely and relevant synthesis of these advances, offering clinicians and researchers an updated perspective on AML as of 2025.
