Integration of SuFEx and Sonogashira Cross-Coupling for the Synthesis of Structurally Diverse Aryl Acetylenes on DNA.

Org Lett

September 2025

Shanghai Institute for Advanced Immunochemical Studies & School of Life Science and Technology, ShanghaiTech University, Shanghai 201210, China.

To address the current limitations of DNA-compatible Sonogashira cross-coupling reactions capable of accommodating a broad range of commercially available phenolic building blocks (BBs), an SuFEx-Sonogashira cross-coupling protocol has been developed. This protocol involves the conversion of readily accessible phenolic compounds into the corresponding aryl fluorosulfates within 96-well microplates via a highly efficient liquid-phase SuFEx reaction, followed by Sonogashira cross-coupling with DNA-conjugated terminal alkynes.

Hydrogen Bond Disruption-Induced Ion Rearrangement in Acetonitrile-Water-Sodium Sulfate Solutions.

J Phys Chem B

September 2025

Key Laboratory of Physics and Technology for Advanced Batteries, College of Physics, Jilin University, Changchun 130012, China.

Understanding hydrogen bonding and ion-specific interactions in water, sodium sulfate (NaSO), and acetonitrile (ACN) systems remains challenging due to their complex, dynamic nature. Here, Raman spectroscopy is employed to probe hydrogen bonding networks and ion reorganization in NaSO aqueous solutions with different ACN concentrations. The results indicate that, at low ACN concentrations in the ternary solutions, hydrogen bonding between ACN and water molecules disrupts the original hydration structure of the ions, resulting in the formation of small ion clusters via electrostatic interactions.

Background: Gastric cancer is one of the most common cancers worldwide, with its prognosis influenced by factors such as tumor clinical stage, histological type, and the patient's overall health. Recent studies highlight the critical role of lymphatic endothelial cells (LECs) in the tumor microenvironment. Perturbations in LEC function in gastric cancer, marked by aberrant activation or damage, disrupt lymphatic fluid dynamics and impede immune cell infiltration, thereby modulating tumor progression and patient prognosis.

Background: Most RNA-seq datasets harbor genes with extreme expression levels in some samples. Such extreme outliers are usually treated as technical errors and are removed from the data before further statistical analysis. Here we focus on the patterns of such outlier gene expression to investigate whether they provide insights into the underlying biology.

With the persistence of difficult employment, a large number of college students feel anxious and nervous about job hunting. College students with different family economic status have various feelings and performances when faced with employment, possibly due to subjective social class differences. The present study investigated the employment confidence of 611 undergraduates in Chongqing, aimed to ascertain the overall employment confidence of Chinese college students, and tried to analyze how subjective social class works on the employment confidence of college students and its influencing mechanism.

Background: Centromeres are crucial for precise chromosome segregation and maintaining genome stability during cell division. However, their evolutionary dynamics, particularly in polyploid organisms with complex genomic architectures, remain largely enigmatic. Allopolyploid wheat, with its well-defined hierarchical ploidy series and recent polyploidization history, serves as an excellent model to explore centromere evolution.

Background: Patent foramen ovale (PFO) has been identified as a potential risk factor for cryptogenic stroke (CS). Although transesophageal echocardiography (TEE) is considered the gold standard for PFO detection, false-negative results remain a clinical concern, particularly in CS patients with high suspicion of PFO-related etiology.

Aims: To evaluate the clinical utility of transcatheter PFO exploration (TPFOE) in CS patients with negative TEE findings but high suspicion of PFO-related etiology.

Histone arginine methylation by protein arginine methyltransferases (PRMTs) is crucial for transcriptional regulation and is implicated in cancers. Despite their therapeutic potential, some PRMTs present challenges as drug targets due to their context-dependent activities. Here, we demonstrate that hypoxia triggers the rapid condensation of PRMT2, which is essential for its histone H3R8 asymmetric dimethylation (H3R8me2a) activity.

State Key Laboratory of Plant Environmental Resilience, College of Life Sciences, Zhejiang University, Hangzhou, 310058, China.

Diurnal floret opening and closure (DFOC) is essential for rice reproductive development and hybrid breeding, yet transcriptional dynamics and underlying regulatory networks remain poorly characterized. Here, we conducted high-temporal-resolution transcriptomic analyses of lodicules to dissect DFOC regulatory networks in two japonica rice cultivars. Analysis of differentially expressed genes (DEGs) uncovered core genes shared by both cultivars, primarily associated with jasmonic acid (JA) signaling and cell wall remodeling.

Engineering resistance genes against tomato brown rugose fruit virus.

Sci China Life Sci

September 2025

MOE Key Laboratory of Bioinformatics and Center for Plant Biology, School of Life Sciences, Tsinghua University, Beijing, 100084, China.

Tomato brown rugose fruit virus (ToBRFV) overcomes all known tomato resistance genes, including the durable Tm-2, posing a serious threat to global tomato production. Here, we employed in vitro random mutagenesis to evolve the Tm-2 leucine-rich repeat (LRR) domain and screened ∼8,000 variants for gain-of-function mutants capable of recognizing the ToBRFV movement protein (MP) and triggering hypersensitive cell death. We identified five such mutants.
