    Axicabtagene Ciloleucel in Large B Cell Lymphoma Ineligible for Autologous Stem Cell Transplantation: The Phase II ALYCANTE Trial

    Investigators conducted a Phase II study, ALYCANTE, to assess the efficacy and safety of a single axi-cel infusion as a second-line therapy in patients with high-risk relapsed/refractory (R/R) large B cell lymphoma deemed ineligible for autologous stem cell transplantation but eligible for CAR-T cell therapy.

    Neutral Sphingomyelinase Blockade Enhances Hematopoietic Stem Cell Fitness through an Integrated Stress Response

    Researchers demonstrated that pharmacologic and genetic inhibition of neutral sphingomyelinase-2 led to sustained improvements in long-term competitive transplantation efficiency after ex vivo culture.

    Pd-1 Instructs a Tumor-Suppressive Metabolic Program that Restricts Glycolysis and Restrains Ap-1 Activity in T Cell Lymphoma

    Using tractable mouse models for T cell non-Hodgkin lymphomas and primary patient samples, investigators demonstrated that PD-1 signaling suppressed T cell malignancy by restricting glycolytic energy and acetyl coenzyme A production.

    ABCC1 and Glutathione Metabolism Limit the Efficacy of Bcl-2 Inhibitors in Acute Myeloid Leukemia

    Using CRISPR/Cas9 screening, researchers found that loss of ABCC1 strongly increased the sensitivity of AML cells to Venetoclax. Genetic and pharmacologic ABCC1 inactivation potentiated the anti-leukemic effects of BCL-2 inhibitors and efficiently re-sensitized Venetoclax-resistant leukemia cells.

    Ppm1d Truncating Mutations Promote the Development of Genotoxic Stress-Induced AML

    Using a transgenic mouse model, scientists demonstrated that truncated protein phosphatase magnesium-dependent 1 delta (PPM1D) reduced self-renewal of HSCs in basal conditions but promotes the development of aggressive AML after exposure to ionizing radiation.

    CBFA2T3-GLIS2-Dependent Pediatric Acute Megakaryoblastic Leukemia Is Driven by GLIS2 and Sensitive to Navitoclax

    Investigators described the development of CBFA2T3-GLIS2-driven mouse models of pediatric acute megakaryoblastic leukemia (AMKL) that recapitulated the phenotypic and transcriptional signatures of the human disease.

    Physiological and Regenerative Functions of Sterile Alpha Motif Protein-14 in Hematopoiesis

    Scientists generated a hematopoietic-specific conditional Samd14 knockout mouse model (Samd14-CKO) to study the role of Samd14 in hematopoiesis. The Samd14-CKO mouse was viable and exhibited no steady-state hematopoietic phenotype.

    Synthesis and Anti-tumor Activities in Human Leukemia-Derived Cells of Polyenylpyrroles with a Methyl Group at the Conjugated Polyene Terminus

    To develop novel drugs for treating T-cell acute lymphoblastic leukemia (T-ALL) and AML, a series of analogs having a polyenylpyrrole structure of natural compounds were synthesized and investigated their structure–activity relationships of in vitro anti-T-ALL and anti-AML activities.

    Impact of Genetic Patterns on Sorafenib Efficacy in Patients with FLT3-Itd Acute Myeloid Leukemia Undergoing Allogeneic Hematopoietic Stem Cell Transplantation: A Multi-Center, Cohort Study

    Scientists explored the efficacy of sorafenib therapy in this population with different concomitant genetic patterns. In a multi-center, cohort study, they enrolled patients with FLT3-ITD AML undergoing allogeneic hematopoietic cell transplantation.
