Objective: To investigate the expression and potential mechanism of calcium/calmodulin-dependent protein kinase II gamma (CaMKIIγ) in patients with acute myeloid leukemia (AML).
Methods: Peripheral blood samples were collected from 90 AML patients, and mononuclear cells were isolated. The expression of CaMKIIγ was measured using real-time quantitative PCR and Western blot. The diagnostic value of CaMKIIγ for AML was assessed, and its correlation with clinical characteristics was analyzed using the clinical data of patients. Additionally, the molecular mechanisms of CaMKIIγ were preliminarily explored.
Results: Compared with the control group, the expression of was significantly upregulated in AML patients. Receiver operating characteristic (ROC) curve analysis showed that could serve as a promising biomarker for distinguishing AML patients from healthy individuals. Furthermore, was significantly correlated with white blood cell (WBC) count and mutation. CaMKIIγ was highly expressed in both newly diagnosed and relapsed AML patients, while decreased during remission. In AML cell lines, the expression levels of CaMKIIγ were all elevated. Inhibition of phosphorylated CaMKIIγ by berbamine led to a decrease in pAKT and pSTAT5 expression.
Conclusion: CaMKIIγ is significantly upregulated in AML patients, and is associated with poor clinicopathological features and unfavorable prognosis. It may serve as a prognostic marker and potential therapeutic target in AML. Its expression may be related to the activation of pAKT and pSTAT5, suggesting that CaMKIIγ may contribute to the development and progression of AML through the activation of the AKT/STAT5 signaling pathway.

Background: Nucleophosmin 1 (NPM1) mutations represent one of the most frequent genetic alterations in acute myeloid leukemia (AML). However, the prognostic significance of concurrent molecular abnormalities and clinical features in NPM1-mutated AML remains to be fully elucidated.
Methods: We retrospectively analyzed 73 adult AML patients with NPM1 mutations.
Background: This study aimed to identify the diagnostic and prognostic ability of serum miR-411-3p in patients with acute myeloid leukemia (AML).
Methods: Blood samples were collected from 60 AML patients and 60 healthy controls to measure serum miR-411-3p and thereafter discuss its potential clinical value.
Results: Serum miR-411-3p was decreased in AML patients and was even lower in those with M4/M5 subtypes or high white blood cell count or adverse cytogenetic risk.
Background: Angioimmunoblastic T-cell lymphoma (AITL) is a rare and aggressive form of peripheral T-cell lymphoma, accounting for 1 - 2% of non-Hodgkin lymphomas. Diagnosis is challenging, and there is no established standard first-line treatment. This case report highlights a rare progression from AITL to therapy-related acute myeloid leukemia (AML-pCT) following cytotoxic chemotherapy.

Methods: Laboratory detection results of multiple gene missense mutations, including NPM1, were analyzed in a case of primary AML with BCR∷ABL.
Results: The patient exhibited morphological features of acute leukemia in the bone marrow.

Background: Polymerase chain reaction (PCR)-based Minimal residual disease (MRD) detection is commonly used for core-binding factor acute myeloid leukemia (CBF-AML), but its interpretation in the context of allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains under discussion.
Method: Using Kyoto Stem Cell Transplantation Group registry data, we included 96 patients who underwent allo-HSCT between 2000 and 2019 for CBF-AML.
Results: To assess MRD, quantitative PCR with GAPDH control was most used.
