    Circular RNAs Drive Oncogenic Chromosomal Translocations within the MLL Recombinome in Leukemia

    Researchers showed that circular RNAs (circRNAs)—a family of covalently closed, alternatively spliced RNA molecules—were enriched within the mixed lineage leukemia (MLL) recombinome and could bind DNA, forming circRNA:DNA hybrids at their cognate loci.

    Embryonic Vitamin D Deficiency Programs Hematopoietic Stem Cells To Induce Type 2 Diabetes

    Scientists demonstrated that transplantation of fetal HSCs made vitamin D deficient in utero induce diabetes in vitamin D-sufficient mice.

    MicroRNA-223 Limits Murine Hemogenic Endothelial Cell Specification and Myelopoiesis

    Researchers identified microRNA (miR)-223 as a negative regulator of murine hemogenic endothelial cell specification and endothelial-to-hematopoietic transition.

    Blockade of IL-6 Signaling Alleviates Atherosclerosis in Tet2-Deficient Clonal Hematopoiesis

    Investigators showed that interleukin-6 (IL-6) receptor antibody treatment reversed the atherosclerosis promoted by Tet2 clonal hematopoiesis, with reduction of monocytosis, lesional macrophage burden, and macrophage colony-stimulating factor 1 receptor expression.

    Abstract

    Distinct Subsets of Multi-Lymphoid Progenitors Support Ontogeny-Related Changes in Human Lymphopoiesis

    Scientists demonstrated that human lymphopoiesis was supported by three waves of embryonic, fetal, and postnatal multi-lymphoid progenitors differing in CD7 and CD10 expression and their output of CD127−/+ early lymphoid progenitors.

    Integrated Multi-Omics Analyses Reveal Homology-Directed Repair Pathway as a Unique Dependency in Near-Haploid Leukemia

    To systematically dissect the unique physiology and uncover susceptibilities that can be exploited in near-haploid leukemia, the authors leveraged single-cell RNA-Seq and computational inference of cell cycle stages to pinpoint key differences between near-haploid and diploid leukemia cells.

    The Pediatric Leukemia Oncoprotein NUP98-KDM5A Induces Genomic Instability That May Facilitate Malignant Transformation

    Researchers investigated the impact of NUP98-KDM5A expression on cellular processes in human pluripotent stem cell models and a patient-derived cell line.

    Basal Type I Interferon Signaling Has Only Modest Effects on Neonatal and Juvenile Hematopoiesis

    Investigators characterized hematopoiesis at several different stages of blood formation, from HSCs to mature blood cells, and found that loss of the IFN-1 receptor led to depletion of several phenotypic HSC and multipotent progenitors subpopulations in neonatal and juvenile mice.

    A Critical Role of RUNX1 in Governing Megakaryocyte-Primed Hematopoietic Stem Cell Differentiation

    By using Runx1F/FMx1-Cre mouse model, scientists discovered that the megakaryocyte (MK)-HSC to MK direct differentiation could occur within 1 cell division, and RUNX1 was an important regulator in the process.

    The Antitumor Effects of WNT5A against Hematological Malignancies

    The authors demonstrated that WNT5A protein upregulated the WNT non-canonical pathway only in leukemic cells, without modulating normal cell behavior.

    Haplodeficiency of the 9p21 Tumor Suppressor Locus Causes Myeloid Disorders Driven by the Bone Marrow Microenvironment

    Researchers reported that mice with germline monoallelic deletion or induced biallelic deletion of the 9p21-syntenic locus developed a fatal myelodysplastic syndrome/myeloproliferative neoplasm-like disease associated with aberrant trabecular bone formation and/or fibrosis in the bone marrow.

    China Grows Blood Stem Cells in Space in What Scientists Say Is First-of-Its-Kind Experiment

    Chinese scientists say they have conducted a first-of-its-kind experiment to produce blood stem cells in space. The stem cells were brought back to Earth by the Shenzhou 15 spacecraft after being cultured for half a month in the Wentian lab module of China’s Tiangong space station.
