Copper's dual role: Reviewing its impact on liver health and disease.

As an essential trace element in the human body, Cu exists in the oxidation states of Cu(II) and Cu(I). The interconversion between these states is closely associated with various redox reactions and plays a pivotal role in cellular respiration regulation, energy metabolism, cell growth regulation, and angiogenesis promotion among other biological processes. As the primary metabolic organ, the liver synthesises and secretes Cu-binding proteins to maintain Cu homeostasis and regulate its metabolism.

Identification and validation of neutrophil-related biomarkers in acute-on-chronic liver failure.

Dysfunction of peripheral blood neutrophils occurs in acute-on-chronic liver failure (ACLF). However, the molecular mechanisms of neutrophils involved in the pathophysiology of the ACLF remains poorly understood. Data downloaded from the GEO database (GSE142255) was used to identify both ACLF and neutrophil-related genes with the help of the limma package and Weighted Gene Co-Expression Network Analysis (WGCNA) algorithms.

Influence of blade installation angle spanwise distribution on the energy characteristics of mining contra-rotating axial flow fan.

As the global demand for energy conservation increases, achieving efficient energy conversion in fans has become a significant challenge in the field of mine ventilation. To investigate the influence of the blade installation angle distribution in the spanwise direction on the energy characteristics of mining counter-rotating axial flow fan, three blade optimization schemes were proposed in this paper. The internal flow field of the fan was obtained by numerical simulation and experimental methods.

The current study assessed the combined effects of LGG and metformin, which play roles in anti-inflammatory and immunoregulatory processes, in alcohol-induced liver disease mice.

The molecular structure of SHISA5 protein and its novel role in primary biliary cholangitis: From single-cell RNA sequencing to biomarkers.

The study collected liver tissue samples from PBC patients and healthy controls and performed transcriptomic analysis of the cells in the samples using single-cell RNA sequencing. The expression characteristics of SHISA5 in PBC were revealed by comparing the difference of SHISA5 protein in the two groups of samples. The structure of SHISA5 protein was predicted and its possible biological function was analysed by bioinformatics method.

The Influence of Fresh Latex Coagulation on the Parameter Characteristics of the Yeoh Hyperelastic Constitutive Model for Natural Rubber.

The coagulation of fresh latex is one of the critical processes that impacts rubber quality during natural rubber processing. Constitutive relationships are the basis for the study of the mechanical properties of rubber materials and serve as a prerequisite for material simulation studies. However, studies on the effect of different coagulation methods on natural rubber constitutive relationships have yet to be carried out, and the current models used for natural rubber constitutive relationships need to be improved.

Association between telomere length and idiopathic normal pressure hydrocephalus: a Mendelian randomization study.

Objective: Idiopathic normal pressure hydrocephalus (iNPH) is highly prevalent among elderly individuals, and there is a strong correlation between telomere length and biological aging. However, there is limited evidence to elucidate the relationship between telomere length and iNPH. This study aimed to investigate the associations between telomere length and iNPH using the Mendelian randomization (MR) method.

NECTIN-4-redirected T cell Antigen Coupler T cells bearing CD28 show superior antitumor responses against solid tumors.

Introduction: T cell Antigen Coupler (TAC) T cells harness all signaling subunits of endogenous T cell receptor (TCR) to trigger T-cell activation and tumor cell lysis, with minimal release of cytokines. Some of the major obstacles to cellular immunotherapy in solid tumors include inefficient cell infiltration into tumors, lack of prolonged cellular persistence, and therapy-associated toxicity.

Methods: To boost the cytotoxic potential of TAC-T cells against solid tumors, we generated a novel NECTIN-4-targeted TAC-T variant, NECTIN-4 TAC28-T, which integrated the co-stimulatory CD28 cytoplasmic region, and compared the anti-tumor activities between NECTIN-4 TAC-T cells and NECTIN-4 TAC28-T cells in vitro and vivo.

Novel insights into cuproptosis in alcoholic liver disease using bioinformatics analysis and experimental validation.

Cuproptosis is crucial in the development of various liver diseases, yet its involvement in alcoholic liver disease (ALD) remains poorly understood. In this study, we screened cuproptosis-related genes (CRGs) regulating ALD and explored their potential molecular mechanisms. Bioinformatic methods were employed to screen CRGs in ALD, analyze their functional enrichment, signaling pathways, transcriptional regulation, relationship with the immune microenvironment and pathogenic genes, and corresponding single nucleotide polymorphism pathogenic regions, and construct transcription factor-miRNA-mRNA networks.

Sulforaphane regulation autophagy-mediated pyroptosis in autoimmune hepatitis via AMPK/mTOR pathway.

Autoimmune hepatitis (AIH) is a liver disease marked by inflammation of unknown origin. If untreated, it can progress to cirrhosis or liver failure, posing a significant health risk. Currently, effective drug therapies are lacking in clinical practice.

YTHDF3 rs7464 A > G polymorphism increases Chinese neuroblastoma risk: A multiple-center case-control study.

Neuroblastoma (NB), a rare childhood cancer originating in nerve tissue. YTHDF3, a member of the YTH domain protein family, is involved in RNA m6A modification and cancer progression. Polymorphisms in YTHDF3 may influence its expression and biological function.

Identification of Potential Causal Genes for Neurodegenerative Diseases by Mitochondria-Related Genome-Wide Mendelian Randomization.

Current research lacks comprehensive investigations into the potential causal link between mitochondrial-related genes and the risk of neurodegenerative diseases (NDDs). We aimed to identify potential causative genes for five NDDs through an examination of mitochondrial-related gene expression levels. Through the integration of summary statistics from expression quantitative trait loci (eQTL) datasets (human blood and brain tissue), mitochondrial DNA copy number (mtDNA-CN), and genome-wide association studies (GWAS) datasets of five NDDs from European ancestry, we conducted a Mendelian randomization (MR) analysis to explore the potential causal relationship between mitochondrial-related genes and Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Lewy body dementia (LBD).

Nicotine aggravates high-fat diet-induced non-alcoholic fatty liver disease in mice via inhibition of CISD3.

Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease globally. Growing data suggests that smoking plays an important role in the evolution of NAFLD. CDGSH iron sulfur domain 3 (CISD3) regulates critical biological activities.

Coenzyme Q10 ameliorates lipopolysaccharide-induced acute lung injury by attenuating oxidative stress and NLRP3 inflammation through regulating mitochondrial dynamics.

Increasing evidence has demonstrated that coenzyme Q10 (CoQ10) exhibits a range of biological properties. Herein, we explored the protective effect and potential molecular mechanism of CoQ10 on lipopolysaccharide (LPS)-induced acute lung injury (ALI). We found that medium (10 mg/kg) and high (50 mg/kg) doses of CoQ10 ameliorated LPS (50 µg/µL)-induced ALI to varying degrees, as demonstrated by reduced lung coefficient, lower wet/dry weight lung tissue ratio, decreased bronchoalveolar lavage fluid protein concentration, less anatomical and histopathological damage to the lung, and increased expression of proteins related to lung epithelial barrier structure.
