An Acquired Phosphatidylinositol 4-Phosphate Transport Initiates T-Cell Deterioration and Leukemogenesis

[Nature Communications] Researchers report that oxysterol-binding protein-related protein 4 L is expressed in adult T-cell leukemia cells but not normal T-cells.

Proteomic and Phosphoproteomic Landscapes of Acute Myeloid Leukemia

[Blood] Scientists identified two cell surface proteins expressed on acute myeloid leukemia blasts of many patients that could represent novel targets for immunologic therapies, and confirmed these targets via flow cytometry.

Bone Marrow Confined IL-6 Signaling Mediates the Progression of Myelodysplastic Syndromes to Acute Myeloid Leukemia

[Journal of Clinical Investigation] The authors found that most of the double knockout mice underwent leukemic transformation at 12-14 months of age. These mice showed myeloblast replacement of a fibrotic bone marrow and widespread leukemic infiltration.

The Development of Pevonedistat in Myelodysplastic Syndrome (MDS) and Acute Myeloid Leukemia (AML): Hope or Hype?

[Therapeutic Advances in Hematology] Researchers summarize the preclinical and clinical rationale for pevonedistat in MDS and AML, review the clinical data of this agent alone and in combination with hypomethylating agents to date, and highlight potential future directions for this agent in myeloid malignancies.

Mission Bio Launches Early Access Program for Single-Cell Measurable Residual Disease Detection in Blood Cancers

[Mission Bio.] Mission Bio, Inc. announced the initial availability of the industry’s first assay capable of determining measurable residual disease in cancer down to the level of individual cells.

EZH2 T367 Phosphorylation Activates p38 Signaling through Lysine Methylation to Promote Breast Cancer Progression

[iScience] Dual inhibition of Enhancer of Zeste Homolog 2 (EZH2) methyltransferase and p38 kinase activities downregulates pEZH2-T367, H3K27me3, and p-p38 pathways in vivo, and reduces triple negative breast cancer growth and metastasis.

Skeletal Muscle SIRT3 Deficiency Contributes to Pulmonary Vascular Remodeling in Pulmonary Hypertension Due to Heart Failure with Preserved Ejection Fractio

[Circulation] Skeletal muscle–specific Sirt3 knockout mice exhibited reduced pulmonary vascular density accompanied by pulmonary vascular proliferative remodeling and elevated pulmonary pressures.

Second-Generation Antipsychotic Quetiapine Blocks Voltage-Dependent Potassium Channels in Coronary Arterial Smooth Muscle Cells

[Journal of Applied Toxicology] Native smooth muscle cells from rabbit coronary arteries were used to investigate the inhibitory effect of quetiapine, an atypical antipsychotic agent, on Kv channels.

miR-34a Is a Tumor Suppressor in Zebrafish and Its Expression Levels Impact Metabolism, Hematopoiesis and DNA Damage

[PLOS Genetics] Through transcriptomic comparisons at 28 hours post-fertilization (hpf), scientists characterized DNA damage-induced transcription, and at 8, 28, and 72 hpf they determined potential miR-34a-regulated genes.
