The Cullin3-Rbx1-KLHL9 E3 ubiquitin ligase complex ubiquitinates Rheb and supports amino acid-induced mTORC1 activation.

Mechanistic target of rapamycin complex 1 (mTORC1) is recruited to the lysosomal membrane by the active Rag heterodimer, where mTORC1 interacts with active Rheb for its activation. It has been shown that polyubiquitination of Rheb is crucial for enhancing its interaction with mTORC1 on the lysosome. However, the specific ubiquitin ligases for Rheb, which promotes mTORC1 activation, remain elusive.

JAG1 mediates apoptosis in herpes simplex keratitis by suppressing autophagy via ROS/JAG1/NOTCH1/pULK1 signaling pathway.

Herpes simplex keratitis (HSK), an ocular disease resulted from herpes simplex virus type 1 (HSV-1) infection, leads to the majority of infectious corneal blindness worldwide. The apoptosis of corneal epithelial cells (CECs) resulted from HSV-1 disrupts the epithelial barrier and exacerbates the infection; however, there is no definitive cure for HSK. Jagged1 (JAG1), one of the primary functional ligands for NOTCH receptors, plays a crucial role in regulating apoptosis and autophagy; however, its role in HSK is unclear.

High internal phase emulsion as a fat replacer: Effect on physico-chemical properties, microstructure and protein digestibility of processed meat during reheating.

Excessive intake of saturated fatty acids poses health risks, necessitating the development of healthier animal fat substitutes. In this study, high internal phase emulsion (HIPE) stabilized by egg yolk-hydroxypropyl distarch phosphate (EY-HPDSP) complex was used as a fat replacer in processed meat. The effect of fat replacement ratios (0 %, 50 %, 100 %) and reheating core temperature (75 ℃, 85 ℃, 95 ℃) on physico-chemical properties, microstructure and protein digestibility of processed meat was investigated.

CENPN contributes to pancreatic carcinoma progression through the MDM2-mediated p53 signaling pathway.

Introduction: We undertook an in-depth investigation of the data pertaining to pancreatic adenocarcinoma (PAAD) to identify potential targets for the development of precision therapies.

Material And Methods: The construction of a protein-protein interaction (PPI) network was based on overlapping differentially expressed genes (DEGs) identified in the GSE16515, GSE32676, and GSE125158 datasets. A subsequent bioinformatic analysis was performed on the interconnected genes within the PPI network, leading to the identification of the central gene, CENPN.

Association between iridocyclitis and immune-related disease: A 2-sample Mendelian randomization study.

The genetic basis of iridocyclitis, an inflammatory eye disease, remains poorly understood, particularly in relation to autoimmune diseases. This study aimed to explore the causal associations between 6 immune-related diseases and iridocyclitis using Mendelian randomization (MR). A total of 230 single nucleotide polymorphisms (SNPs) significantly associated with systemic lupus erythematosus, ankylosing spondylitis (AS), rheumatoid arthritis (RA), Graves disease (GD), Crohn disease (CD), and allergic contact dermatitis were identified based on stringent MR assumptions.

Generating Biomedical Knowledge Graphs from Knowledge Bases, Registries, and Multiomic Data.

As large clinical and multiomics datasets and knowledge resources accumulate, they need to be transformed into computable and actionable information to support automated reasoning. These datasets range from laboratory experiment results to electronic health records (EHRs). Barriers to accessibility and sharing of such datasets include diversity of content, size and privacy.

Stimuli-Responsive Photoluminescent Molecular Tweezers for Highly Enantioselective Discrimination of Chiral Primary Amines.

To address the challenge of chiral recognition in terms of efficiency and generality, we propose a novel fluorescence sensing approach by rationally designing metal-ion-responsive chiral molecular tweezers. The flexible and adaptable molecular tweezers enable facile recognition of 31 structurally varied chiral primary amine compounds, including amino acids, amino acid esters, and chiral amines. Notably, upon stimulation by zinc ions, the chiral molecular tweezers demonstrate a higher enantioselective fluorescence response.

Development and Evaluation of a Novel Chimeric Genotype VII Newcastle Disease Vaccine: Overcoming Maternal Antibody Interference and Spray Administration.

Newcastle disease virus (NDV) poses a significant threat to the poultry industry, with the emergence of genotype VII NDV leading to extensive outbreaks and economic losses. Vaccination is the primary means of controlling NDV, but the presence of maternal antibodies (MDAs) can interfere with the immunological effect of live virus vaccines. Thus, we constructed a chimeric NDV live virus vaccine, LX-OAI4S, by replacing the extracellular regions of the F and HN genes of the NDV LX strain with the corresponding regions of the A-VII vaccine strain.

CTNND1 affects trophoblast proliferation and specification during human embryo implantation.

The placenta, serving as the crucial link between maternal and infant, plays a pivotal role in maintaining a healthy pregnancy. Placental dysplasia can lead to various complications, underscoring the importance of understanding trophoblast lineage development. During peri-implantation, the trophectoderm (TE) undergoes differentiation into cytotrophoblast (CTB), syncytiotrophoblast (STB), and extravillous trophoblast (EVT).
