Protein‐Driven Copper Redox Regulation: Uncovering the Role of Disulphide Bonds and Allosteric Modulation

Angewandte Chemie International Edition, EarlyView.
Copper binding triggers structural changes that expose a reactive disulphide bridge, enabling intrinsic Cu(II) reduction in folded proteins. SAXS, XAS, and QM/MM simulations reveal how globular proteins such as HSA and SOD1 employ disulphide‐mediated dynamics to modulate site accessibility and control copper redox chemistry.

Physiological and molecular mechanisms of exogenous salicylic acid in enhancing salt tolerance in tobacco seedlings by regulating antioxidant defence system and gene expression

Frontiers in Plant Science
IntroductionSalt stress has emerged as a predominant abiotic factor that jeopardizes global crop growth and yield. The plant hormone salicylic acid (SA) has notable potential in mitigating salt toxicity, yet its mechanism in enhancing the salinity ...

TWEAK/Fn14 signaling drives oxidative cardiac injury in systemic lupus erythematosus: Evidence from patient biomarker studies, lupus mouse models, and cardiomyocyte assays

Arthritis &Rheumatology, Accepted Article.
Objective Cardiac involvement is a major cause of morbidity in systemic lupus erythematosus (SLE). Tumor necrosis factor–like weak inducer of apoptosis (TWEAK) is elevated in SLE, but its contribution to lupus‐associated cardiac injury is unclear. We investigated the role of TWEAK/Fn14 signaling in SLE‐related cardiomyopathy and its potential as a ...

Desulfovibrio‐Hydrogen Sulfide Mediates Capsaicin‐Induced Oxidative Stress and Gut Inflammation via TXNIP/NLRP3 Pathway

Food Bioengineering, EarlyView.
ABSTRACT The intake of capsaicin can disrupt the gut microecology and impact health, yet its underlying mechanism is not fully elucidated. This study, by establishing capsaicin‐induced human microbiota‐associated (HMA) mouse models revealed the molecular mechanism by which capsaicin perturbs the gut microbiota and metabolites, leading to intestinal ...

Real‐time quality and safety monitoring of fruit juice using paper‐based platform

Food Biomacromolecules, EarlyView.
Schematic illustration of a paper‐based biosensor for rapid detection of fruit juice spoilage. Abstract Food spoilage and safety concerns still remain critically challenging within the fruit juice industry, especially as conventional detection methods, though precise, are often too time‐consuming, costly, and reliant on centralized laboratories.

Role of antioxidative system during the development and senescence of cucumber fruit

Biologia Plantarum, 2012
The oxidative processes and antioxidative system in cucumber (Cucumis sativus L.) fruit were determined during development and senescence. Four distinct developmental stages could be delineated during fruit maturation: immature (3-8 d after anthesis, DAA)
