    TOP STORY

    Cis Inhibition of NOTCH1 through JAGGED1 Sustains Embryonic Hematopoietic Stem Cell Fate

    Scientists demonstrated that Notch activity was highest in a subset of, GFI1 +, HSC-primed hemogenic endothelium cells, and is gradually lost with HSC maturation.

    Ferritin-Mediated Mitochondrial Iron Homeostasis Is Essential for the Survival of Hematopoietic Stem Cells and Leukemic Stem Cells

    The authors reported that conditional deletion of ferritin heavy chain 1 in the hematopoietic system reduced the number and repopulation capacity of HSCs.

    Abstract

    Targeting TNF/IL-17/MAPK Pathway in hE2A-PBX1 Leukemia: Effects of OUL35, KJ-Pyr-9, and CID44216842

    Scientists established a stable and heritable zebrafish line expressing human E2A-PBX1 (hE2APBX1) for high-throughput drug screening.

    Abstract

    Enhancement of PRMT6 Binding to a Novel Germline GATA1 Mutation Associated with Congenital Anemia

    The C-terminal GATA1 undergoes frameshifting translation as a consequence of GATA1 germline mutation.To investigate the specific function and pathogenic mechanism of this mutant, in vitro mutant models of stable re-expression cells were generated.

    Abstract

    T/Myeloid Mixed Phenotype Acute Leukemia Harboring TLX3::BCL11B with TLX3 Activation

    Researchers reported two cases of T/myeloid MPAL harboring BCL11B-associated structural variants that activate TLX3 by genome sequencing and transcriptomic analyses.

    Abstract

    Rituximab Added to Conditioning Regimen Significantly Improves Erythroid Engraftment in Major Incompatible ABO-Group Hematopoietic Stem Cell Transplantation

    The authors evaluated the efficacy of pre-transplant infusion of rituximab in patients with ABO-incompatibility in improving red blood cell engraftment after HSC transplantation, measured by time to reach transfusion independence.

    An Iron Rheostat Controls Hematopoietic Stem Cell Fate

    Investigators uncovered a role for transitory free cytoplasmic iron as a rheostat for adult stem cell fate control. They found that hematopoietic stem and multipotent progenitor cells harbored comparatively small amounts of free iron.

    The Dark Side of Stemness – the Role of Hematopoietic Stem Cells in Development of Blood Malignancies

    The authors review the evidence supporting the role of preleukemic HSCs in different types of blood cancers, as well as present the alternative models of malignant evolution.
