    Erythroid Overproduction of Erythroferrone Causes Iron Overload and Developmental Abnormalities in Mice

    Scientists generated three lines of transgenic mice with graded erythroid overexpression of erythroferrone and showed that they developed dose-dependent iron overload, impaired hepatic BMP signaling and relative hepcidin deficiency.

    Cytoplasmic NEAT1 Suppresses AML Stem Cell Self-Renewal and Leukemogenesis through Inactivation of Wnt Signaling

    The authors reported an adverse effect of NEAT1, showing that the short isoform, NEAT1_1 suppressed acute myeloid leukemia (AML) development. NEAT1_1 was downregulated in leukemia stem cells and its decreased expression correlated with recurrence in AML patients.

    BUB1B and circBUB1B_544aa Aggravate Multiple Myeloma Malignancy through Evoking Chromosomal Instability

    Investigators elucidated that the expression of BUB1B increased strikingly in multiple myeloma patients and was closely correlated with poor outcomes. Overexpression of BUB1B facilitated cellular proliferation and induced drug resistance in vitro and in vivo, while genetic targeting BUB1B abrogated this effect.

    Leukemic Progenitor Cells Enable Immunosuppression and Post-Chemotherapy Relapse via IL-36–Inflammatory Monocyte Axis

    Researchers showed that abnormal IL-36 production activated by NF-κB was an essential feature of mouse and human leukemic progenitor cells.

    Insufficiency of FZR1 Disturbs HSC Quiescence by Inhibiting Ubiquitin-Dependent Degradation of RUNX1 in Aplastic Anemia

    Scientists reported that FZR1 was downregulated in severe aplastic anemia HSCs compared with healthy control and was associated with decreased quiescence of HSCs.

    Abstract

    Posttransplant Blockade of CXCR4 Improves Leukemia Complete Remission Rates and Donor Stem Cell Engraftment without Aggravating GVHD

    The authors found that posttransplant treatment with the CXCR4 antagonist AMD3100 significantly improved the eradication of leukemia cells in the bone marrow in patient-derived xenograft mice grafted with B cell acute lymphoblastic leukemia cells from multiple patients.

    Abstract

    Aberrantly Reduced Expression of miR-342-5p Contributes to CCND1-Associated Chronic Myeloid Leukemia Progression and Imatinib Resistance

    Investigators used next-generation sequencing to explore endogenous miRNAs in chronic myeloid leukemia (CML) patients and found that miR-342-5p was downregulated and had a significant inhibitory effect on cell proliferation in CML.

    p300 Suppresses the Transition of Myelodysplastic Syndromes to Acute Myeloid Leukemia

    Scientists identified a tumor suppressor role of the acetyltransferase p300 in clinically relevant myelodysplastic syndromes models driven by mutations in the epigenetic regulators TET2, ASXL1, and SRSF2.
