    SIRT1 Is Downregulated by Autophagy in Senescence and Aging

    Researchers report that macroautophagy, a catabolic membrane trafficking pathway that degrades cellular components through autophagosomes and lysosomes, mediated the downregulation of mammalian SIRT1 protein during senescence and in vivo aging.

    Abstract

    Ibrutinib
    Suppresses Early Megakaryopoiesis but Enhances Proplatelet Formation

    The authors investigated the mechanism by which ibrutinib induces thrombocytopenia using cord blood CD34+ hematopoietic stem cells, a human megakaryoblastic cell line, and C57BL/6 mice.

    Abstract

    Loss
    of FGFR3 Accelerates Bone Marrow Suppression-Induced Hematopoietic Stem and Progenitor Cell Expansion by Activating FGFR1-ELK1-Cyclin D1 Signaling

    Investigators showed that fibroblast growth factor receptor 3 (FGFR3) inactivation accelerated bone marrow suppression-induced hematopoietic stem and progenitor cell expansion by upregulating FGFR1 and its downstream transcriptional factor, ELK, which regulates the expression of Cyclin D1 gene at the level of transcription.

    ZBTB38 Is Dispensable for Antibody Responses

    Researchers found that ZBTB38, a different member of the broad complex, tram track, bric-a-brac and zinc finger family that binds methylated DNA at CpG motifs, was highly expressed by germinal center B cells and plasma cells.

    Haploidentical
    HSCT with Post Transplantation Cyclophosphamide versus Unrelated Donor HSCT in Pediatric Patients Affected by Acute Leukemia

    Researchers retrospectively compared the outcome of pediatric patients undergoing T-replete haploidentical HSCT for acute leukemia with those undergoing transplantation from unrelated HLA-matched donor and HLA mismatched unrelated donor from 2012 to 2017 at our Center.

    Abstract

    Outcomes
    of Second Hematopoietic Stem Cell Transplantation Using Reduced‐Intensity Conditioning in an Outpatient Setting

    Outpatient second hematoprogenitors transplant after reduced‐intensity conditioning at a single academic center was analyzed. Twenty‐seven consecutive adults who received an allogeneic hematopoietic stem cell transplantation (allo‐HSCT) after an initial auto‐ or allo‐HSCT from 2006 to 2019 were included.

    Abstract

    Hematopoietic
    Stem Cell Transplantation in Children and Adolescents with Nonremission Acute Lymphoblastic Leukemia

    This retrospective analysis aimed to investigate the outcomes associated with hematopoietic stem cell transplantation (HSCT), and the risks of HSCT in children and adolescents with nonremission acute lymphoblastic leukemia.

    The
    Role of Autophagy in Targeted Therapy for Acute Myeloid Leukemia

    Scientists review studies on the role of autophagy in acute myeloid leukemia (AML) development and summarize the linkage between autophagy and several recurrent genetic abnormalities in AML, highlighting the potential of capitalizing on autophagy modulation in targeted therapy for AML.
