    TOP STORY

    Mobilization-Based Chemotherapy-Free Engraftment of Gene-Edited Human Hematopoietic Stem Cells

    The authors showed that mobilizers created an opportunity for seamless engraftment of exogenous cells, which effectively outcompeted those mobilized, to repopulate the depleted bone marrow.

    Regulation of Human T Cell Leukemia Virus Type 1 Antisense Promoter by Myocyte Enhancer Factor-2C in the Context of Adult T Cell Leukemia and Lymphoma

    Scientists delineated the activity of transcription factor myocyte enhancer factor-2 family members, which were found to be enriched at the 3’LTR and play an important role in the pathogenesis of adult T cell leukemia and lymphoma.

    Abstract

    A Cellular Hierarchy Framework for Understanding Heterogeneity and Predicting Drug Response in Acute Myeloid Leukemia

    To understand how disease heterogeneity links with therapy response, researchers determined the leukemia cell hierarchy makeup from bulk transcriptomes of more than 1,000 patients through deconvolution using single-cell reference profiles of leukemia stem, progenitor and mature cell types.

    Abstract

    Dual Function NFI Factors Control Fetal Hemoglobin Silencing in Adult Erythroid Cells

    Investigators identified via a CRISPR–Cas9 genetic screen two members of the NFI transcription factor family — NFIA and NFIX — as HBG1/2 repressors.

    Abstract

    Regulation of Proton Partitioning in Kinase-Activating Acute Myeloid Leukemia and Its Therapeutic Implication

    Sodium/hydrogen exchanger (NHE1)-mediated intracellular alkalization played a key pathogenetic role in transmitting the proliferative signal from mutated-kinase and could be exploited for therapeutic intervention in AML.

    Schlafen2 Is a Regulator of Quiescence in Adult Murine Hematopoietic Stem Cells

    To investigate the role of schlafen2 (Slfn2) in the regulation of HSCs, scientists studied HSC function in the elektra mouse model, where the elektra allele of the Slfn2 gene contained a point mutation causing loss of function of the Slfn2 protein.

    Abstract

    DNA Methylation Safeguards the Generation of Hematopoietic Stem and Progenitor Cells by Repression of Notch Signaling

    Scientists used multi-omics approaches together with functional assays to assess global DNA methylome dynamics during the endothelial cells-to-hematopoietic stem and progenitor cells transition in zebrafish, and determined that DNA methyltransferase 1 was essential for HSPC generation via repression of Notch signaling.

    Abstract

    Indoxyl Sulfate Impairs In Vitro Erythropoiesis by Triggering Apoptosis and Senescence

    CD34+ hematopoietic stem cells were isolated from human umbilical cord blood and differentiated toward erythrocyte lineage for 14 days in various concentrations of indoxyl sulfate (IS). The effects of IS on cell proliferation, differentiation, apoptosis, and senescence were determined.

    Abstract

    High CRP-Albumin Ratio Predicts Poor Prognosis in Transplant Ineligible Elderly Patients with Newly Diagnosed Acute Myeloid Leukemia

    Researchers found, for the first time, that C-reactive-protein/albumin ratio at diagnosis predicted the prognosis of elderly patients with newly diagnosed AML treated without hematopoietic stem cell transplantation.

    G-CSF/GM-CSF-Induced Hematopoietic Dysregulation in the Progression of Solid Tumors

    The authors focus on the abnormal pathological hematopoietic differentiation in cancer induced by tumor-released granulocyte colony stimulating factor (G-CSF) and granulocyte-macrophage colony stimulating factor (GM-CSF).
