Elucidating the Biosynthesis and Function of an Autoinducing Peptide in Clostridium acetobutylicum.

Clostridia produce autoinducing peptides (AIPs) regulated by the accessory gene regulator (Agr) quorum sensing system, playing a critical role in intercellular communication. However, the biosynthetic pathway and regulatory functions of clostridial AIPs remain inadequately characterized. In this study, we employed chemical quantification, genetic investigations, and in vitro reconstitution experiments to elucidate the native Ca-AIP in Clostridium acetobutylicum, a prominent industrial producer of acetone, butanol, and ethanol.

GAMG alleviates liver fibrosis through inducing ferroptosis in inflammatory macrophages via the IRF1/SLC7A11 signaling pathway.

The activation of inflammatory macrophages plays a pivotal role in the development of liver fibrosis (LF). Ferroptosis contributes to the clearance of inflammatory macrophages and the release of profibrotic factors. Glycyrrhetic Acid 3-O-Mono-β-d-glucuronide (GAMG) is a natural compound, the potential role of which on LF remains uncertain.

East Asian Gene flow bridged by northern coastal populations over past 6000 years.

Coastal areas of northern East Asia in the ShanDong region, which show complex cultural transitions in the last 10,000 years, have helped to facilitate population interactions between more inland regions of mainland East Asia and islands such as those in the Japanese archipelago. To examine how ShanDong populations changed over time and interacted with island and inland East Asian populations, we sequenced 85 individuals from 11 ancient sites in the ShanDong region dating to ~6000-1500 BP. We found that ancestry related to ShanDong populations likely explains the mainland East Asian ancestry observed in post-Yayoi populations from the Japanese archipelago, particularly recent populations who lived in the Ryukyu Islands after ~2800 BP.

Dynamic history of the Central Plain and Haidai region inferred from Late Neolithic to Iron Age ancient human genomes.

The peopling history of the Yellow River basin (YR) remains largely unexplored due to the limited number of ancient genomes. Our study sheds light on the dynamic demographic history of the YR by co-analyzing previously published genomes and 31 newly generated Late Neolithic to Iron Age genomes from Shandong in the lower YR and the Central Plain in the middle YR. Our analysis reveals the population structure in Shandong and the Central Plain in the Late Neolithic Longshan cultural period.

Upcycling of spent LiCoO: engineering the coordination-trapping behavior towards conversion-type anodes for advanced Li-storage.

Basic Considerations for Data Pooling Strategy in Multi-Regional Clinical Trials (MRCTs).

The National Medical Products Administration of China has been implementing ICH E17, which describes the general principles for planning and designing of multi-regional clinical trials (MRCTs), yet there are several ambiguities in the execution and conduct remains in China or East Asia. In specific, pooling strategy, effect modifiers (EMs), statistical analysis, sample size allocation and their impact in alignment with global trial remains a challenge. In this paper, we explore on the criteria mentioned above under the context of China.

Separating nanobubble nucleation for transfer-resistance-free electrocatalysis.

Electrocatalytic gas-evolving reactions often result in bubble-covered surfaces, impeding the mass transfer to active sites. Such an issue will be worsened in practical high-current-density conditions and can cause sudden cell failure. Herein, we develop an on-chip microcell-based total-internal-reflection-fluorescence-microscopy to enable operando imaging of bubbles at sub-50 nm and dynamic probing of their nucleation during hydrogen evolution reaction.

Insights into excitonic behavior in single-atom covalent organic frameworks for efficient photo-Fenton-like pollutant degradation.

The generation of radicals through photo-Fenton-like reactions demonstrates significant potential for remediating emerging organic contaminants (EOCs) in complex aqueous environments. However, the excitonic effect, induced by Coulomb interactions between photoexcited electrons and holes, reduces carrier utilization efficiency in these systems. In this study, we develop Cu single-atom-loaded covalent organic frameworks (Cu/COFs) as models to modulate excitonic effects.

Basic Considerations for the Consistency Evaluation Based on ICH E17 Guideline.

In the International Council for Harmonisation (ICH) guidance on General Principles for Planning and Design of Multi-Regional Clinical Trials (E17), it is important to evaluate the consistency of treatment effect across regions in a multi-regional clinical trial (MRCT). In this paper, we elaborated on some basic considerations to evaluate consistency. We first list the design considerations, and then provide consistency evaluation and interpretation on pharmacokinetics, pharmacodynamics, efficacy, safety, and benefit-risk.

Multiomic characterization, immunological and prognostic potential of SMAD3 in pan-cancer and validation in LIHC.

SMAD3, a protein-coding gene, assumes a pivotal role within the transforming growth factor-beta (TGF-β) signaling pathway. Notably, aberrant SMAD3 expression has been linked to various malignancies. Nevertheless, an extensive examination of the comprehensive pan-cancer impact on SMAD3's diagnostic, prognostic, and immunological predictive utility has yet to be undertaken.

Supervillin-Mediated ZO-1 Downregulation Facilitates Migration of Cisplatin-Resistant HCT116 Colorectal Cancer Cells.

Supervillin (SVIL), the biggest member of the villin/gelsolin superfamily, has recently been reported to promote the metastasis of hepatocellular carcinoma by stimulating epithelial-mesenchymal transition (EMT). However, little is known about the roles of SVIL in the migration of colorectal cancer cells. Here, we investigated the effects of SVIL on the migration of cisplatin-resistant colorectal cancer cells.

Neuropathic Pain Induced by Spinal Cord Injury from the Glia Perspective and Its Treatment.

Regional neuropathic pain syndromes above, at, or below the site of spinal damage arise after spinal cord injury (SCI) and are believed to entail distinct pathways; nevertheless, they may share shared defective glial systems. Neuropathic pain after SCI is caused by glial cells, ectopic firing of neurons endings and their intra- and extracellular signaling mechanisms. One such mechanism occurs when stimuli that were previously non-noxious become so after the injury.
