    TOP STORY

    From a Drug Repositioning to a Structure-Based Drug Design Approach To Tackle Acute Lymphoblastic Leukemia

    Scientists presented the development of a potent inhibitor of deoxycytidine kinase by applying an iterative multidisciplinary approach, which relied on computational design coupled with experimental evaluations.

    Young Donor Hematopoietic Stem Cells Revitalize Aged or Damaged Bone Marrow Niche by Transdifferentiating into Functional Niche Cells

    Researchers showed that disabling HSCs based on disrupting autophagy accelerated niche aging in mice, whereas transplantation of young, but not aged or impaired, donor HSCs normalized niche cell populations and restored niche factors in host mice carrying an artificially harassed niche.

    Deletion of CD36 Exhibits Limited Impact on Normal Hematopoiesis and the Leukemia Microenvironment

    Cd36 knockout mice were evaluated for blood analysis, hematopoietic stem cells and progenitors function and phenotype analyses, and T cells in vitro expansion and phenotypes in comparison with wild-type mice.

    Mutation Spectrum of FLT3 and Significance of Non-Canonical FLT3 Mutations in Hematological Malignancy

    Investigators profiled the spectrum of Fms-like tyrosine kinase 3 (FLT3) mutations in 869 consecutively newly diagnosed AML, myelodysplastic syndrome, and acute lymphoblastic leukemia patients.
    [British Journal of Haematology]

    Abstract

    Single-Cell Gene and Isoform Expression Analysis Reveals Signatures of Aging in Hematopoietic Stem and Progenitor Cells

    Researchers presented an integrated short- and long-read single-cell RNA-seq analysis of hematopoietic stem and progenitor cells. They demonstrated that over half of genes detected in standard short-read single-cell analyses were expressed as multiple, often functionally distinct, isoforms.

    Cell-Cell Interactome of the Hematopoietic Niche and Its Changes in Acute Myeloid Leukemia

    Scientists presented a high-resolution characterisation of the bone marrow (BM) niche in health and AML by establishing a single-cell gene expression database of 339,381 BM cells.

    DHX9-Mediated Pathway Contributes to the Malignant Phenotype of Myelodysplastic Syndromes

    The authors analyzed the expression of DHX9 and its clinical significance in 120 myelodysplastic syndrome (MDS) patients and 42 non-MDS controls. Lentivirus-mediated DHX9 knockdown experiments were performed to investigate its biological function.

    Hematopoietic Reconstitution Dynamics of Mobilized- and Bone Marrow-Derived Human Hematopoietic Stem Cells after Gene Therapy

    Investigators presented an unplanned exploratory analysis evaluating the hematopoietic reconstitution kinetics, engraftment, and clonality in 13 pediatric Wiskott-Aldrich syndrome patients treated with autologous lentiviral-vector transduced hematopoietic stem/progenitor cells.

    Neurodegenerative Disease after Hematopoietic Stem Cell Transplantation in Metachromatic Leukodystrophy

    Three metachromatic leukodystrophy patients treated with hematopoietic stem cell transplantation with a progressive clinical course despite stable white matter pathology were clinically and radiologically analyzed.

    GATA2 Deficiency: Predisposition to Myeloid Malignancy and Hematopoietic Cell Transplantation

    Scientists review the clinical manifestations of GATA2 deficiency, characterization of the hematologic abnormalities and progression to myeloid malignancy, and current hematopoietic cell transplantation practices and outcomes.

    INDUSTRY AND POLICY NEWS

    NIH Toughens Enforcement of Delayed Clinical Trials Reporting

    The US National Institutes of Health (NIH) delivered a stern warning to two in-house clinical researchers who had broken an important rule. They had failed to submit the results of two clinical trials they had overseen to ClinicalTrials.gov, a database meant to inform the public about human studies and their results.
