AI Article Synopsis
- The study aimed to identify potential protein biomarkers for acute myeloid leukemia (AML) to assist in diagnosis and monitoring using less invasive methods.
- Researchers analyzed serum proteins from 12 AML patients and 12 healthy individuals, comparing their protein patterns through advanced techniques like mass spectrometry.
- Eight differentially expressed proteins were identified, with some being downregulated and others upregulated in AML patients, indicating their potential as diagnostic and monitoring tools pending further research.
Article Abstract
Objective: Acute myeloid leukemia (AML) develops as the consequence of a series of genetic changes in a hematopoietic precursor cell. However, the definitive diagnostic protein biomarkers for AML are still unclear. In our study to identify the biomarkers for an initial diagnosis, detection of relapse, and monitoring the minimal residual disease in AML by a less invasive method, serum proteins reflecting alterations in their proteomes were analyzed.
Materials And Methods: We compared the two-dimensional electrophoresis patterns of human sera of 12 patients with AML with those of 12 normal subjects. The differentially expressed spots were identified by matrix-assisted laser desorption/ionization time-of-flight and electrospray ionization quadupole time-of-flight mass spectrometries.
Results: Eight proteins that expressed differentially in the AML group were found. The expression levels of alpha-2-HS-glycoprotein, complement-associated protein SP-40, 40, RBP4 gene product, lipoprotein C-III, and an unknown protein were downregulated in serum of AML patients, whereas the other three proteins, including immunoglobulin heavy-chain variant, proteosome 26S ATPase subunit 1, and haptoglobin-1 were upregulated.
Conclusion: These results suggest that these proteins can be used as less invasive diagnostic and monitoring biomarkers of AML if further studies are done.

An 8 yr old, male, mixed-breed dog was presented with a 2 mo history of progressive weakness, worsened in the last 2 days before examination. Neurological examination revealed ambulatory tetraparesis, ataxia, and proprioceptive deficits in all four limbs. Menace response was reduced in the right eye and discomfort was detected on neck manipulation.

The lysine acetyltransferase 6A (KAT6A, MOZ, MYST3) is a member of the MYST family of protein acetyltransferases, which are essential for different biological processes such as craniofacial, embryonic, stem cell development, and hematopoiesis. KAT6A is an oncogene in human acute myeloid leukemia (AML), and KAT6A overexpression in AML is associated with metastases and poor prognoses. Furthermore, KAT6A mutations play an important role in cancer formation and progression and result in therapeutic resistance in both hematopoietic malignancies and solid tumors.

Tandem duplications (TDs) in exons of upstream binding transcription factor (UBTF-TD) are a rare recurrent alteration in pediatric and adult acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS)/neoplasm. Although recently identified, AML with UBTF-TD is now considered a distinct subtype of AML. To further our understanding of myeloid neoplasms with UBTF-TD, we analyzed clinical, morphologic, and immunophenotypic characteristics of 27 pediatric patients with UBTF-TD-positive myeloid neoplasm, including 21 diagnosed as AML and 6 as MDS.

Background: Patients with lysine methyltransferase 2a (KMT2A)-rearranged (KMT2A-r) acute myeloid leukemia (AML) are assigned to intermediate-risk and adverse-risk categories at diagnosis. However, the value of molecular measurable residual disease (MRD) status in patients who have KMT2A-r AML before allogeneic hematopoietic stem cell transplantation (allo-HSCT) in adult cohorts has rarely been evaluated.
Methods: Patients with KMT2A-r AML who achieved complete remission and subsequently underwent allo-HSCT between January 2015 and January 2023 were included in this analysis.

Pancytopenia is defined as a decrease in all three myeloid cell lines, usually from a precipitating factor such as an autoimmune condition, prescription drug, or several other factors. The etiology of pancytopenia can be determined through laboratory testing, a peripheral blood smear, and a thorough history and physical examination. Trimethoprim-sulfamethoxazole (TMP/SMX, also known by the brand name of Bactrim® or Septra®) is known to cause pancytopenia in rare cases.
