    Acquired miR-142 Deficit in Leukemic Stem Cells Suffices to Drive Chronic Myeloid Leukemia into Blast Crisis

    Investigators showed lower levels of miR-142 in CD34+CD38 blasts from blast crisis (BC) chronic myeloid leukemia (CML) patients than in those from chronic phase CML patients, suggesting that miR-142 deficit was implicated in BC evolution.

    GPRC5C Drives Branched-Chain Amino Acid Metabolism in Leukemogenesis

    Targeting the branched-chain amino acids transporter SLC7A5 with JPH203 inhibited oxidative phosphorylation and elicited strong anti-leukemia effects, specifically in mouse and patient AML samples while sparing healthy bone marrow cells.

    Targeting Cytohesin-1 Suppresses Acute Myeloid Leukemia Progression and Overcomes Resistance to ABT-199

    Researchers investigated the prognostic role and functional significance of cytohesin-1 (CYTH1) in AML. Analysis of AML patient data from the GEPIA and BloodSpot databases revealed that CYTH1 was significantly overexpressed in AML and independently correlated with prognosis.

    Integrated Single Cell Analysis Shows Chronic Alcohol Drinking Disrupts Monocyte Differentiation in the Bone Marrow

    Investigators profiled monocytes and hematopoietic stem cell progenitors from chronic heavy alcohol drinking rhesus macaques using a combination of functional assays and single-cell genomics.

    FUS-ERG Induces Late-Onset Azacitidine Resistance in Acute Myeloid Leukemia Cells

    Scientists investigated whether azacitidine (Aza) was effective against FUS-ERG. Stable Ba/F3 transfectants with FUS-ERG were repeatedly exposed to Aza for seven days of treatment and at 21-day intervals to investigate Aza sensitivity.

    Functional and Molecular Profiling of Hematopoietic Stem Cells During Regeneration

    Researchers analyzed the different phases of regeneration following transplantation. They found that regenerating HSCs initially produced rapidly expanding progenitors and displayed distinct changes in fatty acid metabolism and glycolysis.

    PRL2 Inhibition Elevates PTEN Protein and Ameliorates Progression of Acute Myeloid Leukemia

    APTEN-knockdown AML animal model was generated to assess the impact of conditional phosphatases of regenerating liver 2 (PRL2) inhibition on the level of PTEN protein and the development and progression of AML.

    The Role of Anti-Thymocyte Globulin in Allogeneic Stem Cell Transplantation (HSCT) from HLA-Matched Unrelated Donors (MUD) for Secondary AML in Remission: A Study from the ALWP /EBMT

    Researchers compared outcomes, of 1609 patients with secondary AML undergoing HSCT in first complete remission from MUD from 2010 to 2021, receiving or not receiving anti-thymocyte globulin.

    Phase I Study of Selinexor in Combination with Salvage Chemotherapy in Adults with Relapsed or Refractory Acute Myeloid Leukemia

    Investigators conducted a Phase I, dose-escalation study of selinexor with mitoxantrone, etoposide, and cytarabine in 23 patients aged < 60 years with relapsed or refractory AML. [Leukemia & Lymphoma]

    A Review of the Role of Zinc Finger Proteins on Hematopoiesis

    The authors shed light on the relationship between zinc finger proteins (ZNF) and the regulation of the hematopoietic tissue. They include works with different designs, including both in vitro and in vivo studies, detailing how ZNF might regulate hematopoiesis.
