    Autologous Ex Vivo Lentiviral Gene Therapy for Adenosine Deaminase Deficiency

    Scientists treated 50 patients with severe combined immunodeficiency due to adenosine deaminase (ADA) with an investigational gene therapy composed of autologous CD34+ hematopoietic stem and progenitor cells transduced ex vivo with a self-inactivating lentiviral vector encoding human ADA.

    Abstract

    Selective Requirement of MYB for Oncogenic Hyperactivation of a Translocated Enhancer in Leukemia

    Investigators generated an EVI1-GFP AML model and applied an unbiased CRISPR/Cas9 enhancer scan to uncover sequence motifs essential for EVI1 transcription.

    Abstract

    Cytokine Combinations for Human Blood Stem Cell Expansion Induce Cell Type- and Cytokine-Specific Signaling Dynamics

    By combining fluorescent biosensors with time-lapse imaging and microfluidics, researchers measured the activity of the extracellular signal-regulated kinase pathway over time in live single human umbilical cord blood HSCs and multipotent progenitor cells.

    Abstract

    Engineered Red Blood Cells as an Off-the-Shelf Allogeneic Anti-Tumor Therapeutic

    The authors engineered red blood cells into artificial antigen-presenting cells presenting a peptide bound to the major histocompatibility complex I, the costimulatory ligand 4-1BBL, and interleukin-12.

    RAS Mutations Drive Proliferative Chronic Myelomonocytic Leukemia via a KMT2A-PLK1 Axis

    Using a multiomics platform and biochemical and molecular studies, scientists showed that in proliferative chronic myelomonocytic leukemia RAS pathway mutations were associated with a unique gene expression profile enriched in mitotic kinases such as polo-like kinase 1.

    A Novel Dual HDAC and HSP90 Inhibitor, MPT0G449, Downregulates Oncogenic Pathways in Human Acute Leukemia In Vitro and In Vivo

    Scientists suggested that the dual inhibition of HDAC and HSP90 could suppress the expression of oncogenic pathways in acute leukemia, and MPT0G449 represented a novel therapeutic for anticancer treatment.

    Biased Action of the CXCR4-Targeting Drug Plerixafor Is Essential for Its Superior Hematopoietic Stem Cell Mobilization

    Investigators showed that while AMD11070 acts as a full antagonist, plerixafor acts biased by stimulating β-arrestin recruitment while fully antagonizing G protein.

    Long-Term Treatment-Free Remission in Patients with Chronic Myeloid Leukemia after Second-Line Nilotinib: ENESTop Five-Year Update

    The ENESTop study evaluated treatment-free remission in patients with chronic myeloid leukemia in chronic phase who had received more than three years of tyrosine kinase inhibitor therapy and achieved sustained deep molecular response only after switching from imatinib to nilotinib.

    Abstract

    Ibrutinib, Fludarabine, Cyclophosphamide, and Obinutuzumab (iFCG) Regimen for Chronic Lymphocytic Leukemia (CLL) with Mutated IGHV and without TP53 Aberrations

    Investigators initiated a Phase II trial for previously untreated patients with CLL with mutated IGHV and absence of del(17p)/TP53 mutation. Patients received iFCG for three cycles.
