Retinoic acid receptor gamma (RARG) belongs to the nuclear receptor superfamily and has 90% homology to RAR alpha (RARA) and RAR beta. The () fusion gene has been implicated in acute promyelocytic leukemia (APL). gene rearrangement has been identified in a rare subtype of acute myeloid leukemia (AML) that resembles APL. To date, only 10 cases of gene rearrangements involving ( [], or []) have been reported. These patients show characteristics similar to APL, including bone marrow morphology, coagulation abnormality, and immunophenotype; however, they are resistant to all-trans retinoic acid and arsenic trioxide treatment. Moreover, there is no optimal therapeutic regimen for this subtype of AML. In this study, we report the clinical presentation and experimental findings of a case of AML with gene fusion similar to APL and review other cases of gene rearrangement described in the literature.

Acute myeloid leukemia (AML) is an aggressive disease with a high relapse rate. In this study, we map the metabolic profile of CD34(CD38) AML cells and the extracellular vesicle signatures in circulation from AML patients at diagnosis. CD34 AML cells display high antioxidant glutathione levels and enhanced mitochondrial functionality, both associated with poor clinical outcomes.

Although acute myeloid leukemia (AML) affects hematopoietic stem cell (HSC)-supportive microenvironment, it is largely unknown whether leukemia-modified bone marrow (BM) microenvironment can be remodeled to support normal hematopoiesis after complete remission (CR). As a key element of BM microenvironment, endothelial progenitor cells (EPCs) provide a feasible way to investigate BM microenvironment remodeling. Here, we find reduced and dysfunctional BM EPCs in AML patients, characterized by impaired angiogenesis and high ROS levels, could be partially remodeled after CR and improved by N-acetyl-L-cysteine (NAC).

Background: Acute myeloid leukemia (AML) is a hematologic tumor with poor prognosis and significant clinical heterogeneity. By integrating transcriptomic data, single-cell RNA sequencing data and independently collected RNA sequencing data this study aims to identify key genes in AML and establish a prognostic assessment model to improve the accuracy of prognostic prediction.
Materials And Methods: We analyzed RNA-seq data from AML patients and combined it with single-cell RNA sequencing data to identify genes associated with AML prognosis.
Objectives: This study aimed to determine the frequency of RUNX1/RUNX1T1 gene rearrangement in acute myeloid leukemia (AML) patients by polymerase chain reaction (PCR) and analyze their clinical, hematological, and morphological features of positive patients.
Patients And Methods: A cross-sectional study was conducted in which newly diagnosed patients with AML were included in the study. A total of 101 AML cases were calculated from the World Health Organization (WHO) formula.

A 35-year-old male patient with acute myeloid leukemia (AML), with hyperleukocytosis, presented with acute myocardial infarction. The individual had acute onset chest pain and reached the hospital within the window period. His electrocardiogram (ECG) revealed ST elevated myocardial infarction (STEMI), ST elevated myocardial infarction, and thrombolysis was performed.
