    TOP STORY

    Distinct and Targetable Role of Calcium-Sensing Receptor in Leukemia

    Scientists showed that a calcium gradient exists in bone marrow microenvironments where HSCs reside and that extracellular calcium (eCa2+) and response to eCa2+ differed between leukemias.

    Single-Cell Analysis Reveals Altered Tumor Microenvironments of Relapse- and Remission-Associated Pediatric Acute Myeloid Leukemia

    Investigators utilized single-cell RNA sequencing to analyze pediatric AML bone marrow samples from diagnosis, end of induction, and relapse timepoints.

    STING Activation in TET2-Mutated Hematopoietic Stem/Progenitor Cells Contributes to the Increased Self-Renewal and Neoplastic Transformation

    Researchers showed that the cyclic guanosine monophosphate-adenosine monophosphate synthase-stimulator of interferon genes (STING) pathway was activated to mediate the effect of Ten-eleven translocation-2 (TET2) deficiency in dysregulated hematopoiesis in mouse models.

    Expression Profiling of Extramedullary Acute Myeloid Leukemia Suggests Involvement of Epithelial–Mesenchymal Transition Pathways

    To test the functional impact of TWIST1 overexpression, scientists treated OCI-AML3s with TWIST1-siRNA or metformin, a drug known to inhibit tumor progression in cancer models.

    Susceptibility of Pediatric Acute Lymphoblastic Leukemia to STAT3 Inhibition Depends on p53 Induction

    Investigators demonstrated that pharmacological or genetic inhibition of signal transducer and activator of transcription 3 (STAT3) resulted in p53 induction and that CRISPR-mediated TP53 knockout substantially reverses susceptibility to STAT3 inhibition.

    Abstract

    Pineal Gland Hormone Melatonin Inhibits Migration of Hematopoietic Stem/Progenitor Cells (HSPCs) by Downregulating Nlrp3 Inflammasome and Upregulating Heme Oxygenase-1 (HO-1) Activity

    Researchers provided evidence that melatonin being a ‘’sleep regulating pineal hormone’’ directly inhibited migration of HSPCs both in vitro migration assays and in vivo during pharmacological mobilization.

    Impact of Proton Therapy on the DNA Damage Induction and Repair in Hematopoietic Stem and Progenitor Cells

    Human CD34+ hematopoietic stem and progenitor cells were exposed to 6 MV X-rays, mid- and distal spread-out Bragg peak protons at doses ranging from 0.5 to 2 Gy.

    Clinical Implications and Dynamics of Clonal Hematopoiesis in Anti-CD19 CAR T-Cell Treated Patients

    Investigators analyzed 110 patients with relapsed/refractory B cell non-Hodgkin lymphoma or acute lymphoblastic leukemia, treated with axicabtagene-ciloleucel, tisagenlecleucel, or brexucabtagene autoleucel.

    OGT Ensures Survival of Mouse Fetal Liver Hematopoietic Progenitors Partly by Regulating Bcl-XL and Oxidative Phosphorylation

    Scientists revealed a novel role for O-linked N-acetylglucosamine transferase (OGT) during embryogenesis, which ensured the survival of fetal liver hematopoietic cells partly by regulating Bcl-xL and oxidative phosphorylation.
