    PI3-Kinase Deletion Promotes Myelodysplasia by Dysregulating Autophagy in Hematopoietic Stem Cells

    To determine whether phosphatidylinositol 3 kinase (PI3K) down-regulation can perturb HSC function, scientists generated a triple knockout mouse model with Pik3ca, Pik3cb, and Pik3cd deletion in hematopoietic cells.

    Novel Evidence That the ABO Blood Group Shapes Erythropoiesis and Results in Higher Hematocrit for Blood Group B Carriers

    To test whether there are functional connections between expression of ABO blood group (BG) antigens and erythropoiesis regulation, researchers investigated hemoglobin and hematocrit values in BG B blood donors compared to BG A.

    Clonal Hematopoiesis Involving DNA Damage Response Genes in Patients Undergoing Lung Transplantation Is Increased

    Investigators performed a cross-sectional cohort study of 85 patients with severe lung disease undergoing transplantation to characterize clonal hematopoiesis prevalence. They evaluated somatic variants using duplex error-corrected sequencing and germline variants using whole exome sequencing.

    Activation of ERK1/2 by MOS and TPL2 Leads to Dasatinib Resistance in Chronic Myeloid Leukemia Cells

    The authors investigated the mechanism of breakpoint cluster region::Abelson murine viral homologue 1-independent dasatinib resistance. The expression and activation level of genes or proteins were evaluated using array CGH, real time PCR, or western blot analysis.

    Ovarian Function and Spontaneous Pregnancy after Hematopoietic Stem Cell Transplantation for Leukemia before Puberty an L.E.A. Cohort Study

    Investigators evaluated ovarian function, occurence of premature ovarian insufficiency, and spontaneous pregnancy in a large cohort of adult survivor women who had received HSC transplant for leukemia before puberty.

    Novel Causative Variants of VEXAS in UBA1 Detected through Whole Genome Transcriptome Sequencing in a Large Cohort of Hematological Malignancies

    To better understand the clinical relevance and biological consequences of ubiquitin-like activating enzyme (UBA1)non-M41 variants, researchers analyzed the whole genome and transcriptome data of 4168 patients with hematological malignancies.

    Impact of Trisomy 19 on Outcome according to Genetic Makeup in Patients with Acute Myeloid Leukemia

    Scientists retrospectively studied 97 AML patients with trisomy 19 (tris-19) treated between 2001 and 2019 within two multicenter study groups. Tris-19 occurred solely in 10, with additional abnormalities in non-complex karyotypes in 8 and within complex karyotypes in 79 patients.
