    Deciphering Cell States and Genealogies of Human Hematopoiesis

    The authors introduced an improved single-cell lineage tracing system based on deep detection of naturally-occurring mitochondrial DNA mutations with simultaneous readout of transcriptional states and chromatin accessibility.
    [Nature]

    Targeting IDH2R140Q and Other Neoantigens in Acute Myeloid Leukemia

    Researchers explored the feasibility of immunotherapeutically targeting neoantigens, which arise from recurrent non-synonymous mutations in AML, and thus represent attractive targets since they are exclusively present on the tumor.
    [Blood]

    Abstract

    PI3Kγ Maintains the Self-Renewal of Acute Myeloid Leukemia Stem Cells by Regulating the Pentose Phosphate Pathway

    Scientists found that while PI3Kγ was highly enriched in leukemia stem cells and critical for self-renewal, it was dispensable for normal hematopoietic stem cells.
    [Blood]

    Abstract

    Increased Iron Uptake by Splenic Hematopoietic Stem Cells Promotes TET2-Dependent Erythroid Regeneration

    The authors showed that iron was increasingly taken up by HSCs during anemia and induced erythroid gene expression and regeneration in a Tet2-dependent manner.

    Caloric Restriction Leads to Druggable LSD1-Dependent Cancer Stem Cells Expansion

    Scientists investigated caloric restriction’s impact on several mouse models of acute myeloid leukemias, including acute promyelocytic leukemia, a subtype strongly affected by obesity.

    Targeting the Epigenetic Reader ENL Inhibits Super-Enhancer-Driven Oncogenic Transcription and Synergizes with BET Inhibition to Suppress Tumor Progression

    Investigators found that the YEATS domain-containing histone acetylation reader ENL (eleven-nineteen leukemia) acted as a key regulator of super-enhancers, which are highly active distal CREs, across cancer types.

    Abstract

    Clonal Barcoding of Endogenous Adult Hematopoietic Stem Cells Reveals a Spectrum of Lineage Contributions

    Researchers used inducible clonal DNA barcoding of endogenous adult HSCs to trace their contribution to major hematopoietic cell lineages in unmanipulated animals.

    Allogenic Hematopoietic Stem Cell Transplantation Outcomes of Patients Aged 55 Years or Older with Acute Myeloid Leukemia or Myelodysplastic Syndromes in China: A Retrospective Study

    The retrospective study enrolled 259 patients aged over 55 years who underwent their first allogenic hematopoietic stem cell transplantation between April 2015 and August 2022.

    Second Haploidentical Bone Marrow Transplantation with Antithymocyte Antibody-Containing Conditioning Regimen for Graft Failure in Eight Patients with Severe Aplastic Anemia

    Eight severe aplastic anemia patients with graft failure with a median age of 12.5 years were retrospectively reviewed.

    The Regulatory Role of CD36 in Hematopoiesis Beyond Fatty Acid Uptake

    CD36 is a transmembrane glycoprotein, located on surface of numerous cell types. The authors aimed to explore regulatory role of CD36 in hematopoiesis beyond fatty acid uptake.
