    Heterochromatin Rewiring and Domain Disruption-Mediated Chromatin Compaction during Erythropoiesis

    Investigators systematically analyzed the higher-order chromatin in purified populations of primary human erythroblasts.

    LYN Kinase Programs Stromal Fibroblasts to Facilitate Leukemic Survival via Regulation of c-JUN and THBS1

    Scientists provided mechanistic evidence that LYN regulated the polarization of stromal fibroblasts to support leukemic progression. LYN was overexpressed in fibroblasts of lymph nodes of chronic lymphocytic leukemia patients.

    Targeting HDAC3 to Overcome the Resistance to ATRA or Arsenic in Acute Promyelocytic Leukemia through Ubiquitination and Degradation of PML-RARα

    Researchers reported that histone deacetylase (HDAC) 3 was highly expressed in the acute promyelocytic leukemia subtype of AML, and the protein level of HDAC3 was positively associated with PML-RARα.
    [Cell Death & Differentiation]

    Abstract

    HSC-Independent Definitive Hematopoiesis Persists into Adult Life

    Scientists found that significant percentages of lymphocytes were not derived from HSCs. Multiple waves of hematopoiesis occured from embryonic day (E) 7.5 to E11.5 endothelial cells, which simultaneously produced HSCs and lymphoid progenitors in adult mice.

    Exendin-4 Attenuates Atherosclerosis Progression via Controlling Hematopoietic Stem/Progenitor Cell Proliferation

    Glucagon-like peptide-1 receptor expression in fluorescence-activated cell sorting-sorted wild-type hematopoietic stem/progenitor cells was determined by capillary western blotting.

    Abstract

    Copper Overload Impairs HSPC Proliferation via Inducing HSF1/SP1 Aggregation and the Subsequently Downregulating FOXM1-Cytoskeleton Axis

    Investigators reported a novel association and the novel potential pathways for copper overload to induce proliferation defects in zebrafish embryonic hematopoietic stem and progenitor cells (HSPCs) via down-regulating expression of foxm1-cytoskeleton axis.

    Peripheral Ischemia Imprints Epigenetic Changes in Hematopoietic Stem Cells to Propagate Inflammation and Atherosclerosis

    The authors used peripheral blood collected from patients with peripheral artery disease and performed hind limb ischemia in Apoe−/− mice fed a Western diet and C57BL/6J mice with a standard laboratory diet.

    Abstract

    Role of Allogeneic Hematopoietic Cell Transplant for Relapsed/Refractory Aggressive B-Cell Lymphomas in the CART Era

    Scientists selected patients with the following characteristics: CART or allogeneic hematopoietic cell transplantation (alloHCT) performed between 2016 and 2021; ≥18 years old; aggressive B-cell lymphomas diagnosis; ≥2 lines of therapy; and either anti-CD19 CART or alloHCT as therapy at relapse.

    The Expression Level of Neuronal Calcium Sensor 1 Can Predict the Prognosis of Cytogenetically Normal AML

    Researchers explored the relationship between the neuronal calcium sensor 1 expression level and cytogenetically normal AML.

    The Roles of Bone Remodeling in Normal Hematopoiesis and Age-Related Hematological Malignancies

    The authors provide a synopsis of the cellular and molecular constituents that participate in bone turnover and their known connections to the hematopoietic compartment.
