    Differential Requirements for Smarca5 Expression during Hematopoietic Stem Cell Commitment

    The hypomorphic allele of SMARCA5 could rescue not only the developmental arrest in hematopoiesis in the hCD2iCre model but also the lethal phenotypes associated with constitutive Smarca5 deletion or Vav1iCre-driven conditional knockout in hematopoietic progenitor cells.

    The Possible Role of the Vasopressin System in Hematopoiesis

    Investigators measured the vasopressin marker copeptin and markers of erythropoiesis, red blood cell distribution width, mean corpuscular volume, erythrocyte volume fraction, leukocyte count, and thrombocyte count in 5312 participants from the Swedish CArdioPulmonary bioImage study.

    KCTD5 Regulates Ikaros Degradation Induced by Chemotherapeutic Drug Etoposide in Hematological Cells

    Researchers showed that the chemotherapeutic drug etoposide reduced the protein levels of several isoforms of Ikaros including IK1, IK2 and IK4, but not IK6 or IK7, by accelerating protein degradation, in leukemic cells.

    Abstract

    Ex Vivo Expansion of Hematopoietic Stem Cells in Two/Three-Dimensional Co-Cultures with Various Source of Stromal Cells

    The capacity of mesenchymal stem cells derived from different sources to support the expansion and maintenance of HSPC was compared with each other.

    Abstract

    Case Report of Pediatric TTMV-Related Acute Promyelocytic Leukemia with Central Nervous System Infiltration and Rapid Accumulation of RARA-LBD Mutations

    Investigators presented a pediatric case that manifested as PML::RARA-negative acute promyelocytic leukemia with central nervous system involvement at onset. The patient experienced both intramedullary and extramedullary relapse one year after undergoing allogeneic hematopoietic stem cell transplantation.

    How CBX Proteins Regulate Normal and Leukemic Blood Cells

    Investigators describe how chromobox (CBX) proteins dictate age-related changes in HSCs and stimulate oncogenic HSC fate decisions, either as canonical polycomb repressive complex 1 members or by alternative interactions, including non-epigenetic regulation.
