Acute myeloid leukemia (AML) is a highly heterogeneous hematological malignancy that increasingly affects the elderly population, with its post-transcriptional landscape remaining largely elusive. Establishing a stable proteomics-based classification system and systematically screening age-related proteins and regulatory networks are crucial for understanding the pathogenesis and outcomes of AML. In this study, we leveraged a multi-omics cohort of 374 newly diagnosed AML patients, integrating proteome, phosphoproteome, genome, transcriptome, and drug screening data.

Precise mapping of leukemic cells onto the known hematopoietic hierarchy is important for understanding the cell-of-origin and mechanisms underlying disease initiation and development. However, this task remains challenging because of the high interpatient and intrapatient heterogeneity of leukemia cell clones as well as the differences that exist between leukemic and normal hematopoietic cells. Using single-cell RNA sequencing (scRNA-seq) data with a curated clustering approach, we constructed a comprehensive reference hierarchy of normal hematopoiesis.

Single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) techniques hold great value in evaluating the heterogeneity and spatial characteristics of hematopoietic cells within tissues. These two techniques are highly complementary, with scRNA-seq offering single-cell resolution and ST retaining spatial information. However, there is an urgent demand for well-organized and user-friendly toolkits capable of handling single-cell and spatial information.

Introduction: Acute myeloid leukemia (AML) is an aggressive blood cancer with high heterogeneity and poor prognosis. Although the metabolic reprogramming of nicotinamide adenine dinucleotide (NAD) has been reported to play a pivotal role in the pathogenesis of acute myeloid leukemia (AML), the prognostic value of NAD metabolism and its correlation with the immune microenvironment in AML remains unclear.

Methods: We utilized our large-scale RNA-seq data on 655 patients with AML and the NAD metabolism-related genes to establish a prognostic NAD metabolism score based on the sparse regression analysis.

Article Synopsis
  • Acute myeloid leukemia (AML) is complex and primarily affects older individuals, with a study of 1,474 newly diagnosed patients revealing significant correlations between aging factors, gender, and genetic variations.
  • The research found that older patients (60+) had a notably poor prognosis, with an increase in gene mutations and a decrease in certain gene fusions as age advanced.
  • The study identified three mutant subgroups within gene fusion-negative AML cases, with CH-MDS-AML being common among older males and linked to worse clinical outcomes, highlighting the relationship between genetic profiles and patient demographics in AML.

A Fe-N conjugated organic polymer (SMP-Fr-Py) was prepared from ferrocene and pyrrole using a Scholl coupling reaction, which significantly improved the performance of Cr(VI) removal compared to the polymer (HCP-Fr-Py) prepared by adding the cross-linker formaldehyde dimethyl acetal (FDA). The results showed that at a pH of 2 and at 25 °C, the removal of Cr(VI) reached 90% for SMP-Fr-Py and only 58% for HCP-Fr-Py after 20 min of reaction. Subsequently, 99% and 78% were achieved after 120 min of reaction, respectively.

Background: Genetic mutations of IKZF1 have been frequently delineated in B-lineage acute leukaemia (B-ALL) but rarely elucidated in acute myeloid leukaemia (AML). IKZF1 mutations confer a poor prognosis in AML, and hotspot mutations of IKZF1, N159Y and N159S tend to occur in B-ALL and AML respectively. However, the pathogenesis of IKZF1 N159S in AML and IKZF1 lineage susceptibility are largely unknown.

The current classification of acute myeloid leukemia (AML) relies largely on genomic alterations. Robust identification of clinically and biologically relevant molecular subtypes from nongenomic high-throughput sequencing data remains challenging. We established the largest multicenter AML cohort (n = 655) in China, with all patients subjected to RNA sequencing (RNA-Seq) and 619 (94.

Article Synopsis
  • A study looked at 1,105 patients with acute promyelocytic leukaemia (APL) from 1990 to 2020 to see how treatment has improved over time.
  • The death rates for patients in the first treatment period were higher (20.2%) compared to those treated with a newer method (7.0%), showing that new treatments help save lives.
  • Some patients are at a very high risk of dying early or relapsing, especially older patients with high white blood cell counts, and they need special treatment to help them better.

Complex biomedical data generated during clinical, omics and mechanism-based experiments have increasingly been exploited through cloud- and visualization-based data mining techniques. However, the scientific community still lacks an easy-to-use web service for the comprehensive visualization of biomedical data, particularly high-quality and publication-ready graphics that allow easy scaling and updatability according to user demands. Therefore, we propose a community-driven modern web service, Hiplot (https://hiplot.

Periodic excitation is a relatively simple and common active control mode. Owing to the advantages of direct access to environmental energy and controllability under periodic illumination, it enjoys broad prospects for application in soft robotics and opto-mechanical energy conversion systems. More new oscillating systems need to be excavated to meet the various application requirements.

Article Synopsis
  • This study explores the timing and methods for assessing measurable residual disease (MRD) in acute myeloid leukemia (AML), suggesting that MRD assessment after two cycles of consolidation treatment is more effective than after induction.
  • The results show that multiparameter flow cytometry (MFC) MRD provides significant prognostic value for relapse-free and overall survival in AML patients, especially when analyzing specific gene mutations.
  • Combining MFC MRD with molecular MRD techniques can enhance risk stratification, though the choice of method should depend on the patient's genetic characteristics related to AML.

Article Synopsis
  • Acute myeloid leukaemia (AML) presents a complex prognosis due to various patient and disease factors, despite new treatment advancements.
  • A study identified several key prognostic factors (like age and genetic mutations) that can help predict overall survival, leading to a predictive model for individual risk assessment.
  • This model shows strong performance in differentiating survival outcomes for young and elderly patients and could assist in treatment decisions, particularly for stem cell transplant eligibility.

Article Synopsis
  • A study compared clinical and genetic characteristics among elderly AML (e-AML), secondary AML (s-AML), and young de novo AML patients, finding distinct mutation patterns and lower blood cell counts in e-AML and s-AML groups.
  • e-AML and s-AML patients had lower rates of complete remission and shorter survival times compared to younger patients, indicating a need for different treatment strategies.
  • Intensive therapy may enhance survival for e/s-AML patients without increasing early death risks, and hematopoietic stem cell transplantation is recommended for treating fit s-AML patients.

Article Synopsis
  • Cytogenetic abnormalities and gene mutations are important independent factors in predicting outcomes for acute myeloid leukemia (AML), influencing key genes linked to blood cell development.
  • A study of 560 newly diagnosed non-M3 AML patients examined gene mutations and expression levels, revealing certain gene expression levels associated with specific cytogenetic issues and prognostic outcomes.
  • The findings suggest that integrating gene expression profiles with mutation status can lead to better classification of AML patients for more accurate prognostic assessments.

A facile and economical one-pot strategy has been developed for the synthesis of water-solute CdTe and CdTe/ZnS core/shell quantum dots (QDs) using tellurium dioxide (TeO2) as a tellurium precursor and thioglycolic acid (TGA) as stabilizer without any pre-treatment and inert atmosphere protection. As-synthesized QDs were characterized by transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), electron diffraction spectroscopy (EDS), X-ray powder diffraction (XRD), UV-vis and photoluminescence (PL). The spherical particles were uniformly distributed with the average diameters of 3.
