    Aspartyl-tRNA Synthetase 2 Orchestrates Iron-Sulfur Metabolism in Hematopoietic Stem Cells via Fine-Tuning Alternative RNA Splicing

    Scientists showed that knockout of aspartyl-tRNA synthetase 2 (Dars2) significantly impaired the maintenance of hematopoietic stem and progenitor cells without involving its tRNA synthetase activity.

    Anti-Leukemia Effects of Omipalisib in Acute Myeloid Leukemia: Inhibition of PI3K/AKT/mTOR Signaling and Suppression of Mitochondrial Biogenesis

    Scientists investigated the anti-proliferative effect of omipalisib in AML cell lines with varied genetic backgrounds. The OCI-AML3 and THP-1 cell lines had a significant response to omipalisib, with IC50 values of 17.45 nM and 8.93 nM, respectively.

    Abstract

    Hematopoietic Stem Cells Suppress Proliferation and Enhance Differentiation of Leukemia Cells Through Regulating Apoptotic and Inflammatory Genes

    Investigators demonstrated the growth-restraining function of HSCs in acute leukemia treatment. The viability, proliferation, apoptosis, and differentiation of leukemia cells were evaluated by cell counting, CCK-8, and flow cytometry analysis.

    Abstract

    RNA-Binding Protein NOVA1 Promotes Acute T-Lymphocyte Leukemia Progression by Stabilizing USP44 mRNA

    The gain- and loss-of-function studies for neotumor ventral antigen-1 (NOVA1) were performed using lentivirus-mediated NOVA1 overexpression/knockdown in Jurkat and CCRF-CEM cells.

    Abstract

    Mutated IKZF1 Is an Independent Marker of Adverse Risk in Acute Myeloid Leukemia

    In a multicenter cohort of 1606 newly diagnosed and intensively treated adult AML patients, researchers found IKZF1 alterations in 45 cases with a mutational hotspot at N159S.

    Allogeneic Hematopoetic Stem Cell Transplant for Patients with Refractory T Cell Lymphomas

    The authors compared transplant outcomes between refractory-T cell non-Hodgkin lymphomas (T-NHL) and Chemosensitive-T-NHL (CS-T-NHL). They reviewed the records of 26 refractory-NHL and 29 CS-T-NHL consecutive patients who underwent allogeneic stem cell transplantation.
