    A Novel and Highly Effective Mitochondrial Uncoupling Drug in T Cell Leukemia

    MB1-47 treatment in T cell acute lymphoblastic leukemia cells robustly inhibited cell proliferation via both cytostatic and cytotoxic effects as a result of compromised mitochondrial energy and metabolite depletion, which severely impaired nucleotide biosynthesis.

    Core-Binding Factor Leukemia Hijacks the T Cell–Prone PU.1 Antisense Promoter

    Researchers showed that transcriptional downregulation of PU.1 was an active process involving an alternative promoter in intron 3 that was induced by RUNX transcription factors driving noncoding antisense transcription.

    Abstract

    TET2 Mutations Are Associated with Hypermethylation at Key Regulatory Enhancers in Normal and Malignant Hematopoiesis

    Investigators reported that TET2 mutations are associated with DNA hypermethylation at enhancer sites in whole blood in clonal hematopoiesis of indeterminate potential and in both granulocytes and mononuclear cells in clonal cytopenia of undetermined significance.

    Regulatory Association of Long Noncoding RNAs and Chromatin Accessibility Facilitates Erythroid Differentiation

    The authors employed HSCs, multipotent progenitor cells, common myeloid progenitor cells, megakaryocyte-erythroid progenitor cells, and erythroblasts from human cord blood as an erythroid differentiation model and explored the coordinated regulatory functions of lncRNAs and chromatin accessibility by integrating RNA-Seq and ATAC-Seq data.

    Oridonin Inhibits DNMT3A R882 Mutation-Driven Clonal Hematopoiesis and Leukemia by Inducing Apoptosis and Necroptosis

    Researchers performed high-throughput screening and identified that oridonin, an ent-kaurene diterpenoid extracted from the Chinese herb Rabdosia rubescens, inhibited DNMT3A R882 mutant leukemic cells at a low-micromolar concentration.

    Comparison of the Blood, Bone Marrow, and Cerebrospinal Fluid Metabolomes in Children with B Cell Acute Lymphoblastic Leukemia

    Investigators profiled end-induction plasma, marrow, and cerebrospinal fluid (CSF) from ten children with b-cell acute lymphoblastic leukemia using liquid chromatography-mass spectrometry.

    Human m6A-mRNA and lncRNA Epitranscriptomic Microarray Reveal Function of RNA Methylation in Hemoglobin H-Constant Spring Disease

    In Hemoglobin H-Constant Spring disease (HbH-CS), most genes were hypo-methylated. This included BCL2A1, which may have played an important role in the process of red blood cell differentiation and development of HbH-CS.

    Venetoclax and Azacitidine Followed by Allogeneic Transplant Results in Excellent Outcomes and May Improve Outcomes versus Maintenance Therapy among Newly Diagnosed AML Patients Older than 60

    The combination of venetoclax and azacitidine has resulted in high response rates in the upfront treatment of acute myeloid leukemia (AML) in patients aged under 75 and patients unfit for intensive chemotherapy. The authors reported outcomes of stem cell transplant-eligible patients treated at their center.

    Abstract

    Allogeneic Hematopoietic Cell Transplantation for Patients with Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN)

    The authors reported on all 17 patients with BPDCN who underwent allogeneic hematopoietic cell transplantation (allo-HCT) at their center between 2000 and 2020, and concluded that allo-HCT provided long-lasting remissions in BPDCN patients, particularly when performed in complete remission.

    Abstract

    Long-Term Outcome of Hyper-CVAD-R for Burkitt Leukemia/Lymphoma and High-Grade B Cell Lymphoma: Focus on CNS Relapse

    Scientists reported the long‐term safety and efficacy of the hyper-cyclophosphamide, vincristine, Adriamycin, and dexamethasone plus rituximab (CVAD-R) regimen in adults with Burkitt leukemia and high-grade B-cell lymphoma, and focused on its efficacy to prevent CNS relapse.

    A Comprehensive Review of the Impact of Obesity on Plasma Cell Disorders

    The authors provide a detailed summary of what is known about the impact of obesity on the pathogenesis of multiple myeloma (MM), its influence on outcomes in MM patients, and discuss potential mechanisms through which obesity is postulated to influence MM risk and prognosis.
