    Endothelial-Leukemia Interactions Remodel Drug Responses Uncovering T-ALL Vulnerabilities

    Since endothelial cells (ECs) can alter drug responses in T cell acute lymphoblastic leukemia (T-ALL), scientists developed an EC/T-ALL co-culture system.
    [Blood]

    Abstract

    STEMCELL has implemented an Environmental Management System that is now ISO 14001-certified.

    Dietary Methionine Starvation Impairs Acute Myeloid Leukemia Progression

    Researchers showed that methionine depletion was a vulnerability in AML that could be exploited therapeutically, and provided mechanistic insight into how cells metabolized and recycled methionine.

    Abstract

    A Lymphatic-Absorbed Multi-Targeted Kinase Inhibitor for Myelofibrosis Therapy

    Investigators demonstrated selectivity and therapeutic efficacy of a potent orally bioavailable multi-functional kinase inhibitor through reduction of downstream kinase activation, amelioration of disease phenotypes, and improved survival in animal models of myelofibrosis.

    Mesenchymal Stromal Cells Improve the Transplantation Outcome of CRISPR-Cas9 Gene-Edited Human HSPCs

    Researchers developed a mesenchymal stromal cell-based co-culture system to optimize transplantation outcome of CRISPR-Cas9 gene-edited human hematopoietic stem and progenitor cells (HSPCs).

    The Antileukemic Activity of Decitabine upon PML/RARA-Negative AML Blasts Is Supported by All-Trans Retinoic Acid: In Vitro and In Vivo Evidence for Cooperation

    Scientists demonstrated cooperative antileukemic effects of decitabine and all-trans retinoic acid on AML cell lines U937 and MOLM-13.

    Selective Inhibition of MCL1 Overcomes Venetoclax-Resistance in a Murine Model of Myelodysplastic Syndromes

    The authors determined in vitro sensitivity of myelodysplastic syndrome (MDS) patient samples to selective inhibitors of B cell lymphoma-2, BCL-XL and myeloid cell leukemia 1 (MCL1). While venetoclax response positively correlated with MDS with excess blasts, all MDS subtypes responded to MCL1 inhibition.

    Abstract

    Erythroid Lineage-Specific Lentiviral RNAi Vectors Suitable for Molecular Functional Studies and Therapeutic Applications

    Investigators generated novel lineage-specific RNA interference (RNAi) lentiviral vectors, H23B-Ery-Lin-shRNA and H234B-Ery-Lin-shRNA, to probe the functions of genes that exert multifaceted roles in hematopoiesis in erythroid cells without affecting other hematopoietic lineages.

    hiPSC-Derived Bone Marrow Milieu Identifies a Clinically Actionable Driver of Niche-Mediated Treatment Resistance in Leukemia

    Scientists developed human induced pluripotent stem cell (hiPSC)-engineered niches to reveal druggable cancer-niche dependencies and revealed that mesenchymal and vascular niche-like hiPSC-derived cells supported ex vivo proliferation of patient-derived leukemia cells and mediated treatment resistance.

    Identification of Key MicroRNAs as Predictive Biomarkers of Nilotinib Response in Chronic Myeloid Leukemia: A Sub-Analysis of the ENESTxtnd Clinical Trial

    The authors analyzed differentially expressed miRNAs in CD34+ chronic myeloid leukemia cells pre- and post-nilotinib therapy from 58 patients enrolled in the Canadian sub-analysis of the ENESTxtnd Phase IIIb clinical trial.

    Abstract

    Outcomes of Two-Step Haploidentical Allogeneic Stem Cell Transplantation in Elderly Patients with Hematologic Malignancies

    Following administration of a preparative regimen, researchers infused donor lymphocytes, followed by cyclophosphamide to induce bidirectional tolerance, then infusion of CD34-selected cells.

    Comparable Survival Outcomes with Haploidentical Stem Cell Transplantation and Cord Blood Transplantation

    Scientists conducted a matched-pair analysis of post-transplant cyclophosphamide-haplo and umbilical cord blood transplantation using the Japanese registry data.

    Abstract

    Longitudinal Proteomics Study of Serum Changes after Allogeneic HSCT Reveals Potential Markers of Metabolic Complications Related to aGvHD

    The authors examined changes in serum proteome via high-performance two-dimensional gel electrophoresis during HSC transplantation (HSCT) to search for diagnostic biomarkers for post-HSCT complications.

    Abstract

    The Role of NK Cells and Their Exosomes in Graft versus Host Disease and Graft versus Leukemia

    Scientists investigate the results of various articles on the role of natural killer (NK) cells in allogeneic hematopoietic cell transplantation and also their exosomes in graft-versus-leukemia.
