Hepatitis B virus (HBV) infection remains a major public health problem, causing nearly one million deaths annually. Nucleoporin 153 (NUP153) is known to facilitate the nuclear entry of the human immunodeficiency virus (HIV) nucleocapsids, and recent studies suggest it also plays a role in HBV nucleocapsids nuclear import. We aimed to investigate the impact of NUP153 on HBV replication and its underlying mechanism.

MCM2 belongs to the microchromosome maintenance [MCM] family and plays an essential role in initiating DNA replication as well as maintaining normal cellular cycle functions. Recent research indicates that there is the abnormal expression of MCM2 in various cancers, such as breast, cervical, ovarian, lung, hepatocellular carcinoma, nephroblastoma, prostate, and pancreatic cancers, where it shows a strong link to tumorigenesis, growth, invasion, migration, and adverse prognosis. Thus, MCM2 could serve as a significant biomarker for the early identification, diagnosis, and prognostic evaluation of multiple cancers.

Long-term erosion by acidic solutions in karst regions leads to continuous deterioration of the physical and mechanical properties at the interfaces of engineering structures, adversely affecting their operational performance. To investigate the degradation patterns of the mechanical properties and corrosion mechanisms of the concrete‒limestone composite (CLC) after exposure to acidic corrosion, three kinds of CLC samples treated with acidic solutions of different pH values were fabricated. Mechanical property analysis was conducted via triaxial compression testing methods.

Background: The influence of the glucagon-like peptide-1 receptor (GLP-1R) on bone metabolism is well-established. However, it has been observed that single nucleotide polymorphisms (SNPs) in the GLP-1R gene can partially affect its function. Therefore, this study aims to investigate the association between SNPs in the GLP-1R gene and postmenopausal osteoporosis (PMOP) within the Chinese Han population.

Endotoxemia, caused by lipopolysaccharides, triggers systemic inflammation and myocardial injury by disrupting mitochondrial homeostasis. This study examines the roles of dual specificity phosphatase 1 (Dusp1) and phosphoglycerate mutase family member 1 (Pgam1) in this process. This study utilized cardiomyocyte-specific knockout ( ) and transgenic ( ) mice, alongside knockout ( ) mice, subjected to LPS-induced endotoxemia.

Ferroptosis is a form of programmed cell death that is distinct from apoptosis. The mechanism involves redox‑active metallic iron and is characterized by an abnormal increase in iron‑dependent lipid reactive oxygen species, which results in high levels of membrane lipid peroxides. The relationship between ferroptosis and gynaecological tumours is complex.

The decline in sperm parameters among obese males has attracted significant scholarly interest. The intestinal microbiota plays a crucial role in obesity, and investigating the intestinal-reproductive axis may offer a novel molecular approach to addressing the decline in male sperm parameters caused by obesity. To clarify whether probiotics, either alone or in conjunction with metformin, can enhance sperm parameters in obese male mice and assess the underlying mechanisms involved.

Article Synopsis
  • * The study identifies protein disulfide-isomerase (P4HB) as a new target for lactylation, showing that aloe emodin prevents lactate binding to P4HB and stabilizes kynurenine metabolism by inhibiting the enzyme GOT2 in damaged mitochondria.
  • * Mechanistically, aloe emodin regulates a pathway involving PTGS2 and SH3GLB1 to reduce mitochondrial dysfunction and oxidative stress, revealing its potential as a therapeutic strategy for radiation-induced heart damage through the modulation of lactylation.

  • Photocatalytic conversion of methane (CH4) to methanol (CH3OH) offers a sustainable way to use natural gas and reduce greenhouse gases, but low-temperature synthesis presents challenges.* -
  • Researchers developed a biomimetic photocatalyst with Fe2O3 nanoclusters and single Fe atoms on carbon nitride, achieving a high methanol production rate of 5.02 mmol·gcat-1·h-1 and a 98.5% selectivity for methanol.* -
  • The study found that the combined function of Fe2O3 and single Fe atoms creates a dual-Fe site that efficiently activates oxygen and enhances the oxidation of methane, aided by light excitation for better reaction kinetics

Background: Glucose-regulated protein 78 (GRP78), as a chaperone protein, can protect the endoplasmic reticulum of cells and is expressed to influence chemoresistance and prognosis in cancer. Deoxypodophyllotoxin (DPT) is a compound with antitumor effects on cancers. DPT inhibits the proliferation of osteosarcoma by inducing apoptosis, necrosis, or cell cycle arrest.

As one of the factors regulating tumour angiogenesis, angiopoietin-4 (ANGPT4), which plays an important role in promoting tumour proliferation, survival, expansion and angiogenesis, is highly expressed in some tumours, such as lung adenocarcinoma, glioblastoma and ovarian cancer. This may be related to the fact that ANGPT4 affects the blood vessels and lymphatic system of the tumour. Specifically, ANGPT4 could play an effective role in promoting cancer by affecting the tyrosine kinase receptor TIE2, ERK1/2 and PI3K/AKT signalling pathways.

Sepsis is a syndrome precipitated by immune dysregulation in response to infection, and represents a pivotal factor in global mortality attributed to diseases. The recent consensus delineates sepsis as a perilous state of organ dysfunction arising from the host's maladaptive reaction to infection. It masks the complexity and breadth of the immune mechanisms involved in sepsis, which is characterized by simultaneous hyperinflammation and immunosuppression.

Multimodal luminescence involves color-tunable and wavelength manageable photon emissions upon variable luminescence pathways in response to different external stimuli, which provides clear visualization and high-level confidentiality for information encryption technologies. Integrating multimodal luminescence into a single matrix is regarded as a feasible strategy but remains a big challenge. In this work, multimodal (photoluminescence, persistent luminescence, upconversion luminescence, and thermally stimulated luminescence) and multicolor luminescence (green, yellow, orange, pink to red) is achieved in CaWO:Yb,Er,Eu phosphor by employing an interplay of traps and rare earth emission centers.
