WWC proteins-mediated compensatory mechanism restricts schwannomatosis driven by loss of function.

NF2-related schwannomatosis, previously known as neurofibromatosis type 2, is a genetic disorder characterized by nerve tumors due to gene mutations. Mice with deletion develop schwannomas slowly with low penetrance, hence inconvenient for preclinical studies. Here, we show that NF2, by recruiting E3 ubiquitin ligases β-TrCP1/2, promotes WWC1-3 ubiquitination and degradation.

Botulinum neurotoxins exploit host digestive proteases to boost their oral toxicity via activating OrfXs/P47.

Botulinum neurotoxins (BoNTs) rank among the most potent toxins and many of them are produced by bacteria carrying the orfX gene cluster that also encodes four nontoxic proteins (OrfX1, OrfX2, OrfX3 and P47). The orfX gene cluster is also found in the genomes of many non-BoNT-producing bacteria, often alongside genes encoding oral insecticidal toxins. However, the functions of these OrfXs and P47 remain elusive.

Network Pharmacology Combined With Metabolomics Reveals the Mechanism of Yangxuerongjin Pill Against Type 2 Diabetic Peripheral Neuropathy in Rats.

Purpose: This study aims to explore the mechanism of Yangxuerongjin pill (YXRJP) in the treatment of diabetic peripheral neuropathy (DPN) by network pharmacology and metabolomics technology combined with animal experiments, and to provide scientific basis for the treatment of DPN.

Methods: In this study, network pharmacology analysis was applied to identify the active compounds, core targets and signal pathways, which might be responsible for the effect of DPN. The DPN model was established by high-fat diet combined with streptozotocin (STZ) injection, and the rats were given administration for 12 weeks.

Beyond Tradition: A MOF-On-MOF Cascade Z-Scheme Heterostructure for Augmented CO Photoreduction.

Metal-organic frameworks (MOFs) are rigorously investigated as promising candidates for CO capture and conversion. MOF-on-MOF heterostructures integrate bolstered charger carrier separation with the intrinsic advantages of MOF components, exhibiting immense potential to substantially escalate the efficiency of photocatalytic CO reduction (CORR). However, the structural and compositional complexity poses significant challenges to the controllable development of these heterostructures.

Topologically Engineered High- Quasi-BIC Metasurfaces for Enhanced Near-Infrared Emission in PbS Quantum Dots.

Enhancing photoluminescence (PL) efficiency in colloidal quantum dots is pivotal for next-generation near-infrared photodetectors, imaging systems, and photonic devices. Conventional methods, especially metal-based plasmonic structures, suffer from large optical losses, which limits their practical use. Here, we introduce a quasi-bound state in the continuum (quasi-BIC) metasurface on a silicon-on-insulator platform, tailored to provide high-quality factor resonances with minimized losses.
