    TOP STORY

    Combined Proteomics and CRISPR‒Cas9 Screens in PDX Identify ADAM10 As Essential for Leukemia In Vivo

    Investigators attempted to identify responsible surface proteins and performed deep proteome profiling on minute numbers of dormant patient-derived xenograft (PDX) leukemia stem cells isolated from mice.

    Hematopoietic Stem and Progenitor Cell Heterogeneity Is Inherited from the Embryonic Endothelium

    Scientists discovered that loss of microRNA (miR)-128 in zebrafish led to an expansion of hematopoietic stem and progenitor cells in the aorta–gonad–mesonephros with different cell cycle states and a skew towards erythroid and lymphoid progenitors.

    Dual Intron-Targeted CRISPR-Cas9-Mediated Disruption of the AML RUNX1-RUNX1T1 Fusion Gene Effectively Inhibits Proliferation and Decreases Tumor Volume In Vitro and In Vivo

    Investigators presented a new dual intron-targeting CRISPR-Cas9 treatment strategy, for targeting t(8;21) found in 5–10% of de novo AML, which efficiently disrupted fusion genes without prior identification of breakpoint location.

    SETBP1 Is Dispensable for Normal and Malignant Hematopoiesis

    Researchers integrated the analysis of primary AML and healthy samples, cancer cell lines, and a newly generated murine model, Vav1-iCre;Setbp1fl/fl. SETBP1 depletion in normal hematopoiesis minimally altered self-renewal, differentiation, or reconstitution in vivo.

    Abstract

    Efficient Megakaryopoiesis and Platelet Production Require Phospholipid Remodeling and PUFA Uptake through CD36

    Scientists showed that megakaryocyte progenitors, megakaryocytes, and platelets presented a unique lipidome progressively enriched in polyunsaturated fatty acid (PUFA)-containing phospholipids.

    Abstract

    Minichromosome Maintenance Protein 10 (McM10) Regulates Hematopoietic Stem Cell Emergence in the Zebrafish Embryo

    Investigators used zebrafish to study the role of mcm10 during embryonic development and showed that mcm10 specifically regulated hematopoietic stem cell (HSC) emergence from the hemogenic endothelium.

    A Phase Ib Trial of AVID200, a TGFβ 1/3 Trap, in Patients with Myelofibrosis

    Researchers conducted an investigator-initiated, multicenter, Phase Ib trial of AVID200 monotherapy in 21 advanced myelofibrosis patients.

    Abstract

    Nonrestrictive Diet Does Not Increase Infections during Post-HSCT Neutropenia: Data from a Multicenter Randomized Trial

    Scientists conducted a multicenter, randomized, non-inferiority trial enrolling all consecutive adult patients undergoing high-dose-induction chemotherapy or hematopoietic stem cell transplantation with the objective to compare Non-Restrictive-Diet versus Protective-Diet.

    Abstract

    Reduced Incidence of Neurologic Complications after Allogeneic Hematopoietic Stem Cell Transplantation with Calcineurin-Free Graft-Versus-Host Disease Prophylaxis

    This retrospective single-center study analyzed the neurologic complications in two subsequent cohorts of patients undergoing allogeneic hematopoietic stem cell transplantation with either calcineurin inhibitors (CNI)-based GVHD prophylaxis or CNI-free prophylaxis.

    Updates in Hematopoietic Cell Transplant and Cellular Therapies That Enhance the Risk for Opportunistic Infections

    The authors update the infectious disease physician on newer advances in hematopoietic cell transplant and cellular therapy, including haploidentical transplant, expanding indications for transplant in older individuals and children, and chimeric antigen receptor T cells.

    Medicine Is Plagued by Untrustworthy Clinical Trials. How Many Studies Are Faked or Flawed?

    In October 2020, John Carlisle reported a startling estimate of the number of clinical-trial studies in medical journals that are fake or fatally flawed. For more than 150 trials, Carlisle got access to anonymized individual participant data and judged that 44% of the trials contained at least some flawed data.
