Blood Podcast American Society of Hematology

On this week's episode we’ll discuss the findings from a long-term follow up study of fludarabine, cyclophosphamide, and rituximab in IGHV-mutated CLL, learn more about the impact of genetic alterations and minimal residual disease in adults with KMT2A-rearranged B-cell precursor ALL, and discuss a pre-clinical study of reinforced immunotherapy for myeloma using a new bispecific antibody-based approach.

In this week's episode we'll discuss if fractionated dosing of gemtuzumab ozogamicin provide additional benefit over a single dose in older adults with AML. Then, we'll consider how the loss-of-function of ENT3 drives histiocytosis. Researchers describe a novel pathway leading to histiocytosis that involves hyperactivation of TLR-MAPKinase signaling. This suggests a potential benefit of MAPKinase -directed targeted therapy in a range of histocytoses. Finally we'll discuss unraveling resistance mechanisms to anti-CD20 treatments in B-cell malignancies. Through alternative splicing, the MS4A1 gene encoding human CD20 generates multiple mRNA isoforms with distinct 5’ untranslated regions. 

In this bonus episode of Blood Podcast, Coordinating Editor, Dr. Jason Gotlib is joined by Drs. Sioban Keel, Margaret Ragni, and Andoni Echaniz-Laguna to discuss the Review Series on RNA Therapeutics in Hematology. The series highlights areas in which RNA therapeutics are most advanced: acute hepatic porphyria, transthyretin amyloidosis, and hemophilia.

In this week's episode we’ll discuss the prognostic significance of splicing factor gene mutations in newly diagnosed AML, learn more about the findings from a multi-omics study of therapy resistance in multiple myeloma, and discuss the effects of KIT ligand deletion on systemic KIT levels and hematopoietic stem cell homeostasis. 

In this week's episode we'll see how targeting the prostacyclin receptor is a promising strategy for regulating hemostasis and thrombosis. Then, we'll learn how new evidence indicates that the progression rate is low in MRD-negative myeloma patients who discontinue post-transplant lenalidomide and dexamethasone maintenance therapy after 2 years. Finally we'll discuss how amphiregulin from leptin receptor-positive niche cells in the bone marrow mediates crosstalk between the niche and hematopoietic stem cells under conditions of DNA repair deficiency and aging.

In this week's episode, we discuss the findings from a phase 2 study of lenalinomide plus rituximab in elderly frail patients with DLBCL, learn more about platelet GP6-mediated neutrophil recruitment in early stages of acute lung injury, and discuss a newly identified isoform of the tyrosine kinase AXL, termed AXL3, in mantle cell lymphoma.
