Summary: This study aimed to evaluate the expression of the S100A10 gene at the mRNA and protein levels in patients with depressive disorders and to determine the impact of p11 in the etiopathogenesis of depression. The results indicate slightly increased S100A10 gene expression in patients with depression, but these values do not reach statistical significance.

Summary: The rare cytogenetic abnormality t(3;12)(q26.2;p13) is associated with myeloid neoplasms, myelodysplasia, and poor prognosis. Common features include myelodysplasia, chromosome 7 abnormalities, and high blast counts. The presence of this abnormality is closely related to MDS-related changes, suggesting it should be included in the list of AML defining abnormalities in the WHO classification.

Summary: T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive T-cell malignancy. Recent studies have shown that T-ALL-secreted small extracellular vesicles (sEV) contain NOTCH1-dependent microRNAs (EV-miRs), which regulate oncogenic pathways and promote the expansion and survival of highly proliferative cell subsets, thereby altering the cell heterogeneity and dynamics of leukemia.

Summary: The study found that DNA methylation patterns were associated with genetic alterations in pediatric patients with acute myeloid leukemia (AML). Specific CpG sites were useful in categorizing patients into different clusters based on methylation levels, which were related to gene expression patterns and prognosis.

Summary: IGFBP7 plays an oncogenic role in acute lymphoblastic leukemia by promoting the perdurance of IGF1R at the cell surface, prolonging insulin/IGF stimulation. Clinical data suggest that IGFBP7 is a valid target for antibody-based therapeutic interventions in ALL.

Summary: Leukemia-initiating cells (LIC) are unique cells in different types of leukemia that have self-renewing capabilities and produce tumors, which are functionally distinct from bulk leukemia cells. Current conventional treatments are not effective in eliminating LICs, hence innovative therapeutics targeting LICs hold promise for developing an effective cure for ALL.

Summary: The updated International Consensus Classification (ICC) of B-acute lymphoblastic leukemia (B-ALL) and T-acute lymphoblastic leukemia (T-ALL) includes revisions to previous subtypes and new entities. The classification incorporates recent clinical, cytogenetic, and molecular data, emphasizing whole transcriptome analysis and gene expression clustering studies. The new classification allows for improved risk stratification and optimized treatment plans for ALL patients.

Summary: Acute myeloid leukemia (AML) is the most common type of acute leukemia in adults. A group of genes called olfactory receptors (ORs) were found to be highly expressed in AML cells. The expression of these ORs could predict the prognosis of AML patients and they have the potential to be used as biomarkers for diagnosis and as targets for new drugs to treat AML.

Summary: TAL1 is frequently dysregulated in T-ALL, and its overexpression is associated with unfavorable clinical outcomes. This study found that the tumor suppressor KLF4 can suppress SE-driven TAL1 expression in T-ALL cells by inhibiting the formation of 5' TAL1 super-enhancer. A small molecule inducer of KLF4, APTO-253, exerts an anti-leukemic effect by targeting SE-driven TAL1 expression in T-ALL cells. Induction of KLF4 may be a promising strategy to control TAL1 expression and could serve as a novel treatment for T-ALL patients with poor prognosis.

Summary: This article reviews the progress of flow cytometry (FCM) in the diagnosis of myelodysplastic syndrome (MDS) in recent years, and provides optimal methods and recommendations for sample processing, antibody panels and fluorochromes, and current hardware technologies. These recommendations will facilitate the appropriate application of FCM assays in the diagnostic workup of MDS patients, but further standardization and harmonization are needed.

The WHO 2016 classification acknowledges the contribution of FCM in the diagnosis of MDS and its potential usefulness in prognostication, prediction, therapy evaluation, and patient follow-up.

Summary: This study examines whether aggregating cortical peptides associated with cognitive resilience into an index can identify older adults with higher or lower cognitive resilience. The results show that a higher index is associated with slower cognitive decline, slower motor decline, lower burden of AD pathologies, and modifies the negative effects of AD pathology on AD dementia proximate to death. These findings suggest that cortical proteins may be potential therapeutic targets for maintaining brain health in aging adults.

Summary: This study evaluated the use of pre-defined flow cytometric markers in the diagnosis of MDS and CMML. The results showed that flow cytometry had a high concordance with the diagnosis of MDS, and could identify cases "in agreement with MDS". Furthermore, the study suggested that a 3% cut-off for myeloid progenitor cells in flow cytometry was more appropriate than the cytomorphologically defined cut-off of 5%.

Summary: The study identified three somatic mutations in the UBA1 gene that are associated with the development of VEXAS syndrome. Additionally, the analysis revealed several putative somatic variants in UBA1 that may contribute to myeloid malignancies, particularly in patients with vacuoles or immunodysregulatory symptoms.

Summary: According to the new classification standards, there have been changes in the diagnosis of leukemia patients, with an increase in the proportion of certain subtypes and the largest group still being genetically defined. The new classifications focus on genetics-based definitions with similar basic concepts and a large degree of agreement.
