AI Article Synopsis

  • A patient with acute myeloid leukemia (AML) had mutations in both NPM1 and FLT3-ITD and received two stem cell transplants.
  • After the second transplant, the patient experienced an extramedullary relapse manifested as granulocytic sarcoma in the right breast, with tumor cells also showing the FLT3-ITD mutation.
  • Treatment with Gilteritinib, a FLT3 inhibitor, led to complete regression of the sarcoma without significant side effects, suggesting it could be an effective therapy for similar relapses.

Article Abstract

Case of a patient with acute myeloid leukemia (AML) positive for mutations in both genes NPM1 and FLT3-ITD who underwent two allogeneic haematopoietic stem cell transplants (HSCT); the second allograft one was followed by extramedullary relapse (granulocytic sarcoma of right breast), with blast cells positive for FLT3-ITDmutation.  Treatment with Gilteritinib, a second generation selective oral type I FLT3 inhibitor, was started after the second HSCT with complete regression of breast granulocytic sarcoma in absence of hematological and extra hematologic toxicity. We conclude that Gilteritinib can represent an effective therapy for extra hematologic relapse, with acceptable toxicity and outpatient management.

CD300a and CD300A, among the CD300 immunoglobulin (Ig)-like receptor family members in mice and humans, respectively, are expressed on myeloid cell lineage. The interaction of CD300a and CD300A with their ligands phosphatidylserine and phosphatidylethanolamine, respectively, exposed on the plasma membrane of dead cells mediate an inhibitory signal in myeloid cells. We previously reported that a neutralizing antimouse CD300a monoclonal antibody (mAb) enhanced efferocytosis by macrophages and ameliorated acute ischemic stroke (AIS) in mice.

Discovery of WDR5-MLL1 and HDAC Dual-Target Inhibitors for the Treatment of Acute Myeloid Leukemia.

J Med Chem

Jiangsu Key Laboratory of Drug Design and Optimization and State Key Laboratory of Natural Medicines, China Pharmaceutical University, Nanjing 210009, China.

Targeting the WDR5-MLL1 protein-protein interaction (PPI) is considered to be an effective approach for the treatment of MLL-rearranged leukemia. However, interfering with WDR5-MLL1 PPI reduces methylated H3K4 levels and induces a decline in acetylated H3 levels, which may contribute to the suboptimal cellular efficacy of WDR5 inhibitors. We observed that cotreatment with WDR5-MLL1 PPI and HDAC inhibitors augmented the antiproliferative effect in MV-4-11 cells.

ALKBH3-mediated m1A demethylation promotes the malignant progression of acute myeloid leukemia by regulating ferroptosis through the upregulation of ATF4 expression.

Hematology

The Basic Medical Laboratory of the 920th Hospital of Joint Logistics Support Force of PLA, The Transfer Medicine Key Laboratory of Cell Therapy Technology of Yunan Province, The Integrated Engineering Laboratory of Cell Biological Medicine of State and Regions, Kunming, Yunnan Province, People's Republic of China.

To investigate the role of ALKBH3 in acute myeloid leukemia (AML), we constructed an animal model of xenotransplantation of AML. Our study demonstrated that ALKBH3-mediated m1A demethylation inhibits ferroptosis in KG-1 cells by increasing ATF4 expression, thus promoting the development of AML. These findings suggest that reducing ALKBH3 expression may be a potential strategy to mitigate AML progression.

Objective: To retrospectively analyze the incidence of infections in elderly acute myeloid leukemia (AML) patients undergoing induction therapy with venetoclax combined with hypomethylating agents and to compare these findings with those from patients receiving standard or low-dose chemotherapy.

Methods: Medical records of 169 elderly (≥60 years old) AML patients diagnosed via MICM (morphology, immunology, cytogenetics, and molecular genetics) at the First Affiliated Hospital of USTC between June 2019 and June 2022 were reviewed. Patients were divided into three groups: venetoclax combined with hypomethylating agents group (targeted therapy group), standard chemotherapy group, and low-dose chemotherapy group.
