    Microglial Hexokinase 2 Deficiency Increases ATP Generation through Lipid Metabolism Leading to β-Amyloid Clearance

    Scientists explored the contribution of energy metabolism to microglial function in Alzheimer’s disease (AD) and demonstrated that hexokinase 2 was elevated in microglia from an AD mouse model and patients.

    SZT2 Maintains Hematopoietic Stem Cell Homeostasis via Nutrient-Mediated mTORC1 Regulation

    Researchers presented that seizure threshold 2 (SZT2), a protein required for mTORC1 downregulation upon nutrient deprivation, was critical for HSC homeostasis, where ablation of SZT2 in HSCs decreased the reserve and impaired the repopulating capacity.

    HSF1 Is a Driver of Leukemia Stem Cell Self-Renewal in Acute Myeloid Leukemia

    Using genetic Hsf1 deletion and a direct heat shock transcription factor 1 (HSF1) small molecule inhibitor, scientists showed that HSF1 was specifically required for the maintenance of AML, while sparing steady-state and stressed hematopoiesis.

    DDX41 Coordinates RNA Splicing and Transcriptional Elongation to Prevent DNA Replication Stress in Hematopoietic Cells

    Scientists demonstrated that loss of DEAD-Box Helicase 41 (DDX41) function impaired efficient RNA splicing, resulting in DNA replication stress with excess R-loop formation in hematopoietic cells.

    Health-Related Quality of Life in Reduced Intensity Hematopoietic Cell Transplantation Based on Donor Availability in Patients Aged 50–75 with Advanced Myelodysplastic Syndrome: BMT CTN 1102

    The primary analysis of this Blood and Marrow Transplant Clinical Trials Network study showed the survival advantage associated with allogeneic hematopoietic cell transplantation in older adults with myelodysplastic syndromes did not come at the cost of worse quality of life.

    Abstract

    Impact of the Time Interval between End of Induction and Autologous Hematopoietic Transplantation in Newly Diagnosed Patients with Multiple Myeloma

    Researchers evaluated the impact of the time interval between end of induction and autologous hematopoietic transplantation on progression-free survival and overall survival in multiple myeloma patients.
