Suppression of Hepatocellular Carcinoma by Deletion of SIRT2 in Hepatocytes via Elevated C/EBPβ/GADD45γ.

Background & Aims: There is a gap in our understanding of mechanisms promoting hepatocellular carcinoma (HCC), and this limits our ability to provide targeted therapy interventions for HCC. In HCC samples, NAD-dependent deacetylase sirtuin 2 (SIRT2) levels are increased and associated with a significantly worse prognosis, but the role of SIRT2 in hepatocarcinogenesis remains controversial.

Methods: To assess the role of SIRT2 in hepatocarcinogenesis, we used a hepatocyte-specific knockout of SIRT2 and two plasmid overexpression HCC models: MET/CAT and AKT/Nras.

Piezo1-related physiological and pathological processes in glioblastoma.

Introduction: Glioblastoma (GBM) is the most malignant of the astrocytomas, primarily involving the cerebral hemispheres and cerebral cortex. It is one of the fatal refractory solid tumors with a 5-year survival rate of only 5% in adults. Cells in biological tissues are subjected to mechanical forces, including hydrostatic pressure, shear stress, compression and tension.

Pd-O-Ti dual sites for efficient electrochemical active hydrogen generation and bromate reduction.

Atomic hydrogen (H*) plays a crucial role in electrochemical reduction technology towards various environmental and energy applications, but suffers from low utilization efficiency arisen from the undesirable H-H dimerization and the competitive adsorption between water molecule with reactants on the traditional adjacent catalytic sites. Herein, we anchored Pd single atoms on the naturally formed titanium oxide of titanium foam to construct Pd-O-Ti dual-site electrocatalyst with spatially isolated water dissociation and H* utilization site, which synchronously inhibits the H-H dimerization and the competitive adsorption of water molecule and targeted reactants. Experiments and theoretical calculations revealed that the Ti-O sites could synergistically dissociate water to H*, which overflowed to nearby Pd single-atom sites for designed reduction reactions and utilization benefiting from the hydrogen spillover ability of titanium oxide substrate.

The restoration of immunity characterized by the recovery of myeloid dendritic cells represent a favorable response to methylprednisolone therapy for HBV-ACLF patients: A prospective cohort study.

Methods: Patients with HBV-ACLF were prospectively allocated to groups given methylprednisolone intravenously (1.

Therapeutic Potential of STE20-Type Kinase STK25 Inhibition for the Prevention and Treatment of Metabolically Induced Hepatocellular Carcinoma.

Background & Aims: Hepatocellular carcinoma (HCC) is a rapidly growing malignancy with high mortality. Recently, metabolic dysfunction-associated steatohepatitis (MASH) has emerged as a major HCC catalyst; however, signals driving transition of MASH to HCC remain elusive and treatment options are limited. Herein, we investigated the role of STE20-type kinase STK25, a critical regulator of hepatocellular lipotoxic milieu and MASH susceptibility, in the initiation and progression of MASH-related HCC.

Multicomponent Reaction Integrating Selenium(II)-Nitrogen Exchange (SeNEx) Chemistry and Copper-Catalyzed Azide-Alkyne Cycloaddition (CuAAC).

Multicomponent reactions (MCRs) are powerful tools for rapidly constructing compound libraries with sufficient molecular diversity and complexity. Herein, to fully leverage a third aspect of molecular diversity enabled by the selenium-nitrogen exchange (SeNEx) reaction between alkynes and benzoselenazolones, a novel CuI-catalyzed three-component reaction has been successfully developed. This reaction integrates SeNEx with CuAAC click chemistry, enabling rapid and regioselective synthesis of 1,4,5-trisubstituted 5-seleno-1,2,3-triazoles with high atom economy and good to excellent yields (65 examples, 50%-95%).

Tailoring monogenic disease carrier screening panels for Chinese populations: The importance of considering regional differences.

Carrier screening for monogenic diseases is becoming increasingly important in preventive medicine, yet selecting appropriate target genes remains a complex task, especially in countries with significant ethnic and geographic diversity such as China. This study aimed to develop a strategy to screen for carrier screening target genes suitable for the Chinese population, considering regional variations in carrier frequencies (CFs). We analyzed a dataset from a large-scale, multicenter carrier screening study, encompassing 33,104 individuals from different regions of China and carrier status for 223 genes.

Duplex qPCR for detecting and differentiating porcine epidemic diarrhea virus GI and GII subtypes.

Introduction: Porcine epidemic diarrhea virus (PEDV) is a pathogen that causes a highly contagious intestinal disease in pigs, which causes significant economic losses to the pig industry worldwide. PCR is the most commonly used technique for PEDV diagnosis in practical clinics, however, reported works still suffer from shortcomings, for example, most of them cannot differentiate GI and GII subtypes, they suffer from low sensitivity, and some primer sequences are no longer able to match the mutant strains.

Methods: To address these issues, we conducted a comprehensive analysis by comparing the sequences of the PEDV S protein in the existing NCBI database with a recently isolated epidemic strain of PEDV, named SX0818-2022, of subtype GIIa from Shanxi, China.

Hantaan virus glycoprotein Gc induces NEDD4-dependent PTEN ubiquitination and degradation to escape the restriction of autophagosomes and facilitate viral propagation.

Hantaan virus (HTNV) infection causes severe hemorrhagic fever with renal syndrome (HFRS) in humans and the infectious process can be regulated by autophagy. The phosphatase and tensin homolog (PTEN) protein has antiviral effects and plays a critical role in the autophagy pathway. However, the relationship between PTEN and HTNV infection is not clear and whether PTEN-regulated autophagy involves in HTNV replication is unknown.

Phenotypic Versus Genetic Mismatch of BMI and Type 2 Diabetes: Evidence From Two Prospective Cohort Studies.

Unlabelled: Little is known about the population-based mismatch between phenotypic and genetic BMI (BMI-PGM) and its association with type 2 diabetes. We therefore used data from the China Kadoorie Biobank and UK Biobank and calculated BMI-PGM for each participant as the difference between the percentile for adjusted BMI at baseline and the percentile for adjusted polygenic risk score for BMI. Participants were categorized into discordantly low (BMI-PGM < the first quartile), concordant (the first quartile ≤ BMI-PGM < the third quartile), and discordantly high (BMI-PGM ≥ the third quartile) groups.

Fractionation and tidal characteristics of per- and polyfluoroalkyl substances in the estuarine maximum turbidity zone.

Complex tidal processes and suspended particulate matter (SPM) behavior influence the land-sea transport of terrestrial contaminants in estuaries. Contaminants are generally trapped within the estuarine maximum turbidity zone (MTZ), where SPM concentrations peak, misleading flux estimation. Here, we conducted high-resolution continuous sampling over two tidal cycles within the MTZ of a semidiurnal estuary.

Association between dietary vitamin E and osteoporosis in older adults in the United States.

Background: Increased oxidative stress due to aging can lead to increased bone loss. The most abundant form of vitamin E, namely α-tocopherol, has high antioxidant properties and biological activity; however, its effect on osteoporosis has not been well studied in humans. We aimed to investigate the association between dietary vitamin E (α-tocopherol) and osteoporosis among older adults in the United States.

A prospective therapeutic strategy: GPX4-targeted ferroptosis mediators.

As a crucial regulator of oxidative homeostasis, seleno-protein glutathione peroxidase 4 (GPX4) represents the primary defense system against ferroptosis, making it a promising target with important clinical application prospects. From the discovery of covalent and allosteric sites in GPX4, substantial advancements in GPX4-targeted small molecules have been made through diverse discovery and design strategies in recent years. Moreover, as an emerging hotspot in drug development, seleno-organic compounds can functionally mimic GPX4 to reduce hydroperoxides.
