    TOP STORY

    Translation Efficiency Driven by CNOT3 Subunit of the CCR4-NOT Complex Promotes Leukemogenesis

    Investigators uncovered CNOT3, a subunit of the CCR4-NOT complex, as an essential modulator of translation in myeloid leukemia. Elevated CNOT3 expression correlated with unfavorable outcomes in patients with AML.

    Autophagy Regulates the Maturation of Hematopoietic Precursors in the Embryo

    Using combined approaches, including scRNA-seq, researchers confirmed that autophagy-related gene 5 deletion interrupted developmental temporal order of endothelial to hematopoietic transition to further affect the pre-HSC I maturation.

    STAT3 Protects Hematopoietic Stem Cells by Preventing Activation of a Deleterious Autocrine Type-I Interferon Response

    The authors developed mixed bone marrow chimeric mice with inducible Stat3 deletion in 20% of the hematopoietic compartment to avoid systemic inflammation. Stat3-deficient HSPCs were significantly impaired in reconstitution ability following primary or secondary bone marrow transplantation.

    Abstract

    NFKBIE Mutations Are Selected by the Tumor Microenvironment and Contribute to Immune Escape in Chronic Lymphocytic Leukemia

    Investigators showed that NFKBIE-mutated CLL cells were selected by microenvironmental signals that activated the NF-κB pathway and induced alterations within the tumor microenvironment that could allow for immune escape.

    Decoding Human In Vitro Terminal Erythropoiesis Originating from Umbilical Cord Blood Mononuclear Cells and Pluripotent Stem Cells

    Scientists mapped an atlas of terminally differentiated cells from umbilical cord blood mononuclear cells and pluripotent stem cells, and observed their dynamic regulation of erythropoiesis at single-cell resolution.

    Abcb10 Regulates Murine Hematopoietic Stem Cell Potential and Erythroid Differentiation

    Researchers showed that the ATP-binding cassette transporter 10 (Abcb10), located on the inner mitochondrial membrane, was essential for HSC maintenance and erythroid lineage differentiation.

    Abstract

    Gilteritinib as Post-Transplant Maintenance for Acute Myeloid Leukemia with Internal Tandem Duplication Mutation of FLT3

    Adults with FLT3-ITD AML in first remission underwent hematopoietic cell transplantation (HCT) and were randomly assigned to placebo or 120mg once daily gilteritinib for 24 months after HCT. The primary end point was relapse-free survival.

    Impact of Clonal Hematopoiesis of Indeterminate Potential on Hepatocellular Carcinoma in Individuals with Steatotic Liver Disease

    Investigators examined whether clonal hematopoiesis of indeterminate potentia was associated with HCC development in patients with steatotic liver disease.

    Predicting the Long-Term Effects of Therapeutic Neutralization of Oncostatin M on Human Hematopoiesis

    Researchers utilized clinical data from studies of an anti-Oncostatin M (OSM) monoclonal antibody in healthy volunteers and systemic sclerosis patients, to quantitatively determine the link between OSM and alterations in red blood cell and platelet production.

    Malignant Progression of Pre-Leukemic Disorders

    Scientists review the mechanisms of progression focusing on the hierarchy of clonal mutation and potential roles of transcription factor alterations, splicing factor mutations, and the bone marrow environment in progression to AML.
