    Inherited Polygenic Effects on Common Hematological Traits Influence Clonal Selection on JAK2V617F and the Development of Myeloproliferative Neoplasms

    Investigators showed that the inherited polygenic loci that underlie common hematological traits influenced JAK2V617F clonal expansion.

    Age-Related Noncanonical TRMT6–TRMT61A Signaling Impairs Hematopoietic Stem Cells

    Scientists observed that RNA N1-methyladenosine-generating methyltransferase TRMT6–TRMT61A complex was increased in aged murine HSCs due to aging-declined CRL4DCAF1-mediated ubiquitination degradation signaling.

    Abstract

    MITOL Deficiency Triggers Hematopoietic Stem Cell Apoptosis via ER Stress Response

    The authors investigated the functional involvement of MITOL in HSC maintenance by generating MX1-cre inducible Mitol knockout mice.

    Inflammatory Recruitment of Healthy Hematopoietic Stem and Progenitor Cells in the Acute Myeloid Leukemia Niche

    In two separate congenic models of AML researchers confirmed by evaluation of the bone marrow plasma secretome and HSPC-selective single-cell RNA sequencing that multipotent progenitors and long-lived stem cells adopted inflammatory gene expression programs.

    ZBP1 Activation Triggers Hematopoietic Stem and Progenitor Cell Death Resulting in Bone Marrow Failure in Mice

    Scientists demonstrated that similar to a RIPK3 deficiency, an MLKL deficiency significantly extended survival and like Ripk3 deficiency partially restored hematopoiesis in Ripk1HEM KO mice revealing that both necroptosis and apoptosis contributed to bone marrow failure in these mice.

    Abstract

    Driver Mutation Zygosity Is a Critical Factor in Predicting Clonal Hematopoiesis Transformation Risk

    Investigators hypothesized that the co-occurrence of CHIP and mCAs at the same locus might have important prognostic implications for malignancy transformation risk.

    Deciphering the Differential Impact of Thrombopoietin/MPL Signaling on Hematopoietic Stem/Progenitor Cell Function in Bone Marrow and Spleen

    Researchers investigated the effects of thrombopoietin (TPO) and its receptor MPL ablation on marrow and splenic hematopoiesis in TPO−/− and MPL−/− mice during aging.

    Association between Clonal Hematopoiesis Driver Mutations, Immune Cell Function, and the Vasculometabolic Complications of Obesity

    297 individuals with overweight and obesity, between the ages of 54 and 81 years, were recruited in a cross‐sectional study. Clonal hematopoiesis driver mutations were identified with an ultrasensitive targeted assay.

    Additive Effects of TPMT and NUDT15 on Thiopurine Toxicity in Children with Acute Lymphoblastic Leukemia across Multiethnic Populations

    The extent of dosage reduction recommended for patients with intermediate activity in both enzymes is currently not clear. Mercaptopurine dosages during maintenance were collected from 1768 patients with acute lymphoblastic leukemia in Singapore, Guatemala, India, and North America.
