Functions of METTL1/WDR4 and QKI as m7G modification - related enzymes in digestive diseases.

N-methylguanosine (m7G) modification is one of the most prevalent forms of chemical modification in RNA molecules, which plays an important role in biological processes such as RNA stability, translation regulation and ribosome recognition. Methyl-transferation of m7G modification is catalyzed by the enzyme complex of methyltransferase-like 1 (METTL1) and WD repeat domain 4 (WDR4), and Quaking (QKI) recognizes internal m7G methylated mRNA and regulates mRNA translation and stabilization. Recent studies have found that m7G modification - related enzymes are associated with the onset and progression of digestive cancer, such as colorectal cancer, liver cancer, and other digestive diseases such as ulcerative colitis.

Stability Study of Anticoagulant Hydrogel Coatings Toward Long-Term Cardiovascular Devices.

Implantable cardiovascular devices have revolutionized the treatment of cardiovascular diseases, yet their long-term functionality without causing thrombosis is a persistent challenge. Although the surface modification of anticoagulant coating has greatly improved the biocompatibility of the devices, its long-term stability in complex physiological environments still remains questionable. Herein, the stability of three anticoagulant hydrogel coatings, poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC), poly(sodium 2-acryloyl-2-methylpropanesulfonate) (PAMPS), and poly(4-styrenesulfonate sodium) (PSS), is studied.

Advancements in Microphysiological systems: Exploring organoids and organ-on-a-chip technologies in drug development -focus on pharmacokinetics related organs.

This study explored the evolving landscape of Microphysiological Systems (MPS), with a focus on organoids and organ-on-a-chip (OoC) technologies, which are promising alternatives to animal testing in drug discovery. MPS technology offers in vitro models with high physiological relevance, simulating organ function for pharmacokinetic studies. Organoids composed of 3D cell aggregates and OoCs mimicking in vivo environments based on microfluidic platforms represent the forefront of MPS.

Naa50 regulates ovule and embryo sac development in Arabidopsis.

N-terminal acetyltransferase Naa50 plays an important regulatory role in ovule development by indirectly promoting cell wall invertase 2/4 expression.

Association of Sleep Duration and Daytime Napping With Risk of Hyperuricemia: A Systematic Review and Meta-Analysis.

Background: Hyperuricemia (HUA), marked by elevated serum urate levels, is increasingly prevalent worldwide. The relationship between lifestyle factors such as sleep duration, daytime napping, and HUA risk remains unclear. Although some studies suggest that sleep variables, including short or long sleep durations and napping, may influence serum uric acid levels, results are inconsistent.
