    Reconstructing the Lineage Histories and Differentiation Trajectories of Individual Cancer Cells in Myeloproliferative Neoplasms

    Researchers quantified the effect of the JAK2-V617F mutation on the self-renewal and differentiation dynamics of HSCs in treatment-naive individuals with myeloproliferative neoplasms and reconstructed lineage histories of individual HSCs using somatic mutation patterns.

    Prolonged Maintenance of Hematopoietic Stem Cells That Escape from Thrombopoietin Deprivation

    Thpo-/- HSCs exhibited profound loss of quiescence, impaired cell cycle progression and increased apoptosis. Thpo-/- HSCs also exhibited diminished mitochondrial mass and impaired mitochondrial bioenergetics.

    Abstract

    OTS167 Blocks FLT3 Translation and Synergizes with FLT3 Inhibitors in FLT3 Mutant Acute Myeloid Leukemia

    OTS167 alone or in combination with tyrosine kinase inhibitors were used to investigate the effect of OTS167 on FLT3 signaling and expression in human Fms-like tyrosine kinase 3 (FLT3) mutant acute myeloid leukemia cell lines and primary cells.

    Modulation of APLNR Signaling Is Required during the Development and Maintenance of the Hematopoietic System

    Investigators generated an Apelin receptor (Aplnr)-tdTomato reporter mouse embryonic stem cell line and showed that hematopoietic stem and progenitor cells were generated exclusively from mesodermal cells that express Aplnr-tdTomato.

    LINC00665 Promotes the Progression of Acute Myeloid Leukemia by Regulating the miR-4458/DOCK1 Pathway

    The relative expression of LINC00665, miR-4458 and DOCK1 in acute myeloid leukemia (AML) samples was measured using qRT-PCR, and the protein level of DOCK1 in AML cell lines was examined using western blot.

    Tissue Factor Pathway Inhibitor Upregulates CXCR7 Expression and Enhances CXCL12-Mediated Migration in Chronic Lymphocytic Leukemia

    Plasma tissue factor pathway inhibitor concentrations were measured by ELISA. Chronic lymphocytic leukemia cells were isolated from patients and used for trans-endothelial migration assays.

    CD74 Is a Regulator of Hematopoietic Stem Cell Maintenance

    Scientists demonstrate that mice lacking CD74 exhibited an accumulation of HSCs in the bone marrow (BM) due to their increased potential to repopulate and compete for BM niches.

    Activation of the MAPK Pathway Mediates Resistance to PI3K Inhibitors in Chronic Lymphocytic Leukemia (CLL)

    Researchers present findings from longitudinal whole-exome sequencing of multiply relapsed CLL patients enrolled in phosphatidylinositol 3-kinase delta (PI3Ki) trials. The non-responder subgroup was characterized by baseline activating mutations in MAP2K1, BRAF and KRAS in 60% of patients.

    Abstract

    Discovery of a Novel CIP2A Variant (NOCIVA) with Clinical Relevance in Predicting TKI Resistance in Myeloid Leukemias

    Scientists report the discovery of a CIP2Asplicing variant, NOCIVA. Characterization of CIP2A variants was performed by both 3′ and 5′ rapid amplification of cDNA ends from cancer cells.

    Abstract

    Effect of Postreinduction Therapy Consolidation with Blinatumomab vs Chemotherapy on Disease-Free Survival in Children, Adolescents, and Young Adults With First Relapse of B-Cell Acute Lymphoblastic Leukemia

    Investigators determined whether substituting blinatumomab for intensive chemotherapy in consolidation therapy would improve survival in children, adolescents, and young adults with high- and intermediate-risk first relapse of B-cell acute lymphoblastic leukemia (B-ALL).

    Genetics of Donor Cell Leukemia in Acute Myelogenous Leukemia and Myelodysplastic Syndrome

    The authors describe the spectrum of genetic aberrations detected in DCL cases in the literature with regard to the character of the individual cases, existing family cohorts that carry individual genes, and functional studies that support etiologic roles in acute myelogenous leukemia development.

    Consequences of Coronavirus Infections for Primitive and Mature Hematopoietic

    Infection with coronaviruses sometimes leads to hematologic complications in patients, and these hematologic complications are associated with poorer prognosis.
