    Transcriptional Signatures of the BCL2 Family for Individualized Acute Myeloid Leukemia Treatment

    From three AML RNA-seq cohorts, scientists constructed the B cell lymphoma-2 (BCL2) family signatures by applying an innovative gene-set selection method reflecting biological knowledge followed by non-negative matrix factorization.

    Bmi1 Suppresses Protein Synthesis and Promotes Proteostasis in Hematopoietic Stem Cells

    Researchers deleted Bmi1 from adult hematopoietic cells and found that this slowly depleted HSCs. Rather than inducing senescence, Bmi1 deficiency increased HSC division.

    Abstract

    The ETS Transcription Factor Spi2 Regulates Hematopoietic Cell Development in Zebrafish

    The authors showed that the expression of spi2 was restricted to hemogenic endothelial cells and to hematopoietic stem and progenitor cells in zebrafish.

    Abstract

    Multiparameter Analysis of Timelapse Imaging Reveals Kinetics of Megakaryocytic Erythroid Progenitor Clonal Expansion and Differentiation

    Scientists analyzed progenitor cell dynamics, including the division rate, velocity, viability, and probability of lineage commitment at the single-cell level over time.

    The CGRP Receptor Antagonist MK0974 Induces EVI1high AML Cell Apoptosis by Disrupting ERK Signaling

    An in vitro experimental system was used to determine the effect of MK0974 on EVI1high AML cell lines. The expression of CRLR and RAMP1-3 in EVI1high and EVI1low AML lines was evaluated by RT–PCR.

    Abstract

    Duplex Sequencing Uncovers Recurrent Low-frequency Cancer-associated Mutations in Infant and Childhood KMT2A-rearranged Acute Leukemia

    To uncover mutations that were below the detection of standard next-generation sequencing (NGS), a combination of targeted duplex sequencing and NGS was applied on 20 infants and 7 children with KMT2A-r acute lymphoblastic leukemia, 5 longitudinal and 6 paired relapse samples.

    A High Hematopoietic Cell Transplantation Comorbidity Index (HCT-CI) Does Not Impair Outcomes After Non-Myeloablative Allogeneic Stem Cell Transplantation in Acute Myeloid Leukemia Patients 60 Years or Older

    Researchers analyzed 289 AML patients 60 years or older undergoing non-myeloablative conditioning-hematopoietic stem cell transplantation. Hematopoietic cell transplantation comorbidity index risk was low, intermediate, or high in 36%, 31%, and 33% of patients, respectively.

    Effects of CD34+ Cell Dose on Hematopoietic Recovery in Acute Lymphoblastic Leukemia Patients with Positive Pretransplant Measurable Residual Disease

    A total of 975 acute lymphoblastic leukemia patients were enrolled and classified into pre-HSCT measurable residual disease (MRD)-positive and MRD-negative subgroups. Cox proportional hazard regression models were built for time-to-event outcomes.

    Immunopathology of Chronic Critical Illness in Sepsis Survivors: Role of Abnormal Myelopoiesis

    Investigators propose that the resulting immunologic endotype is secondary to a persistent maladaptive reprioritization of myelopoiesis and pathologic activation of myeloid cells.
