Hydrogeochemical mechanism of Li-Cs-rich thermal springs in the Karakoram Fault, Qinghai-Xizang Plateau: New insights from multiple stable isotopes.

High lithium (Li) and cesium (Cs) concentrations in the Qinghai-Xizang Plateau thermal springs pose environmental and health challenges, but their origins and enrichment mechanisms remain unclear. This study focuses on the Sogdoi geothermal field, located along the southern Karakoram Fault, to investigate these processes. Multi-isotope analyses (H, O, Li, Sr) reveal that Li and Cs predominantly originate from the host rocks, especially granitoids and meta-sedimentary rocks, rather than from magmatic fluids.

HIG-2 promotes glioma stemness and radioresistance mediated by IGFBP2-rich microparticles in hypoxia.

Hypoxia can weaken the efficacy of radiotherapy and decrease tumor immunogenicity leading to immune escape. Thus, a thorough understanding of the key signaling pathways regulated by hypoxia is vitally important to enhance the radiosensitivity and improve immunosuppressive microenvironment of glioma. In this study, we verified the crucial role of hypoxia-inducible gene 2 (HIG-2) in lipid droplet (LD) accumulation and demonstrated that HIG-2 binding to frizzled class receptor 10 (FZD10) activated Wnt/β-catenin signaling pathway and increased its downstream insulin-like growth factor binding protein 2 (IGFBP2) level in microparticles (MPs) derived from glioma stem cells (GSCs), leading to decreased radiosensitivity and immunogenicity of MPs-receiving cells via the cross-talk between GSCs and non-stem glioma cells (GCs).

Objective: Methionine synthetase (MS) A2756G and Cystathionine-β-synthase (CBS) 844ins68 gene polymorphisms were indicated to be associated with increased coronary artery disease (CAD) risk. Nevertheless, because the results of each experiment are different, there is no consensus till now. This meta-analysis aimed to clarify the relationship between MS gene A2756G and CBS gene 844ins68 polymorphisms and CAD.

A widespread family of ribosomal peptide metallophores involved in bacterial adaptation to metal stress.

Ribosomally synthesized and posttranslationally modified peptides (RiPPs) are a structurally diverse group of natural products that bacteria employ in their survival strategies. Herein, we characterized the structure, the biosynthetic pathway, and the mode of action of a RiPP family called bufferins. With thousands of homologous biosynthetic gene clusters throughout the bacterial phylogenetic tree, bufferins form by far the largest family of RiPPs modified by multinuclear nonheme iron-dependent oxidases (MNIO, DUF692 family).
