Proteomic subtypes enrich current acute myeloid leukemia nomenclature and reflect intrinsic pathogenesis alongside aging.

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.

Sohlh1 Modulates the Stemness and Differentiation of Glioma Stem-Like Cells by Inactivation of Wnt/β-Catenin Signalling Pathway via SFRP1.

Glioma stem-like cells (GSLCs) are tumour initiating cells that drive tumorigenesis and progression through self-renewal and various differentiation potencies. Therefore, the identification of genes required for GSLC stemness and differentiation is vital for the development of novel targeted therapies. Sohlh1 belongs to the superfamily of bhlh transcription factors and serves as a tumour suppressor in glioma.

GPCR signaling contributes to immune characteristics of microenvironment and process of EBV-induced lymphomagenesis.

Epstein-Barr virus (EBV) is the oncogenic driver of multiple cancers. However, the underlying mechanism of virus-cancer immunological interaction during disease pathogenesis remains largely elusive. Here we reported the first comprehensive proteogenomic characterization of natural killer/T-cell lymphoma (NKTCL), a representative disease model to study EBV-induced lymphomagenesis, incorporating genomic, transcriptomic, and in-depth proteomic data.

Molecular characterization and pathogenesis of H9N2 avian influenza virus isolated from a racing pigeon.

H9N2 avian influenza viruses (AIVs) can cross species barriers and expand from birds tomammals and humans. It usually leads to economic loss for breeding farms and poses a serious threat to human health.This study investigated the molecular characteristics of H9N2 AIV isolated from a racing pigeon and its pathogenesis in BALB/c mice and pigeons.

Lead toxicity induces autophagy to protect against cell death through mTORC1 pathway in cardiofibroblasts.

Heavy metals, such as lead (Pb(2+)), are usually accumulated in human bodies and impair human's health. Lead is a metal with many recognized adverse health side effects and yet the molecular processes underlying lead toxicity are still poorly understood. In the present study, we proposed to investigate the effects of lead toxicity in cultured cardiofibroblasts.

Nitrifying biocathode enables effective electricity generation and sustainable wastewater treatment with microbial fuel cell.

Simultaneous organics removal and nitrification using a novel nitrifying biocathode microbial fuel cell (MFC) reactor were investigated in this study. Remarkably, the introduction of nitrifying biomass into the cathode chamber caused higher voltage outputs than that of MFC operated with the abiotic cathode. Results showed the maximum power density increased 18% when cathode was run under the biotic condition and fed by nitrifying medium with alkalinity/NH4+-N ratio of 8 (26 against 22 mW/m2).

Estimation of allele frequency in pooled DNA by using PCR-RFLP combined with microchip electrophoresis.

Biallelic marker, most commonly single nucleotide polymorphism (SNP), is widely utilized in genetic association analysis, which can be speeded up by estimating allele frequency in pooled DNA instead of individual genotyping. Several methods have shown high accuracy and precision for allele frequency estimation in pools. Here, we explored PCR restriction fragment length polymorphism (PCR-RFLP) combined with microchip electrophoresis as a possible strategy for allele frequency estimation in DNA pools.

[Effects of different delivery routes of CD34+ stem cells on cardiac function in the ischemic cardiomyopathy of rats].

Objective: To compare the effects of CD34-positive stem cells delivered by different routes on cardiac function in rats with ischemic cardiomyopathy, and to evaluate the efficacy and safety of stem cell transplantation.

Methods: Sixty-four male Wistar rats were randomized into cell infusion group (n=30), acute myocardial infarction (AMI) model group (n=20) and sham operation group (n=14). AMI model was reproduced by ligation of left anterior descending coronary artery.

Poly[μ-aqua-diaqua-(μ(3)-N'-carboxy-methyl-ethylenediamine-N,N,N'-tri-acetato)oxidopotassium(I)vanadium(IV)].

In the crystal structure of the title compound, [KV(C(10)H(13)N(2)O(8))O(H(2)O)(3)](n), the V(IV) ion adopts a distorted octa-hedral geometry, coordinated by one oxide group, two N and three carboxylate O atoms from the same N'-carboxy-methyl-ethyl-ene-diamine-N,N,N'-triacetate (HEDTA) ligand. The potassium ion is hepta-coordinated by two water mol-ecules, two bridging water mol-ecules and three carboxylate O atoms from three neighbouring HEDTA ligands. The HEDTA ligands and some of the water mol-ecules act as bridges, linking the compound into a three-dimensional architecture via 2(1) screw, c-glide, translation and inversion symmetry operators.

Simultaneous organics removal and bio-electrochemical denitrification in microbial fuel cells.

Simultaneous organics removal and bio-electrochemical denitrification using a microbial fuel cell (MFC) reactor were investigated in this study. The electrons produced as a result of the microbial oxidation of glucose in the anodic chamber were transferred to the anode, which then flowed to the cathode in the cathodic chamber through a wire, where microorganisms used the transferred electrons to reduce the nitrate. The highest power output obtained on the MFCs was 1.

[Effects of adenovirus-mediated gene transfer of ICOSIg fusion protein on experimental autoimmune myocarditis in Lewis rats].

Objective: To explore the effects of adenovirus vector-mediated gene transfer of ICOSIg fusion protein on experimental autoimmune myocarditis (EAM) in Lewis rats.

Methods: Expression vector containing ICOSIg (p-Adeno-ICOSIg) was constructed by fusion of human ICOS and IgGFc segment. Adenovirus vector was digested by PacI enzyme and transfected into HEK 293 cells.

[IL-10 gene modification on immature dendritic cells induces antigen-specific tolerance in experimental autoimmune myocarditis].

Objective: To investigate whether IL-10 gene modification on immature dendritic cells (iDC) could induce autoimmune tolerance in rat experimental autoimmune myocarditis (EAM).

Methods: EAM was induced by cardiac myosin immunization on day 0 and day 7 in rats. A total of 2 x 10(6) mature DC (mDC), iDC, pcDNA3 transfected iDC, pcDNA3-IL-10 transfected iDC or PBS were injected intravenously at 5th immunization day.

Antigen-specific tolerance induced by IL-10 gene modified immature dendritic cells in experimental autoimmune myocarditis in rats.

Background: Experimental autoimmune myocarditis (EAM) in rats is a T-cell-mediated disorder. The initiation and maintenance of autoimmune responses in EAM depend on the maturation state of dendritic cells. IL-10 is a pleiotrophic immunomodulatory cytokine that functions at different levels of the immune response, so it has emerged as a promising therapeutic factor for the treatment of autoimmune/inflammatory diseases.
