Nanozymes at the Bio‐Nano Interface: From Synthesis, Defect Engineering, Catalytic Behavior in Biological Microenvironments, and Biosafety Implications

Advanced Materials Interfaces, EarlyView.
Nanozymes (NZs) have emerged as versatile artificial enzymes with tunable catalytic properties driven by atomic coordination, defect engineering, and surface chemistry. This review presents a bio–nano interface framework linking synthesis strategies, structural design, and catalytic behavior within complex biological microenvironments.

GSH‐Responsive Nanoparticles Enhance Hepatocellular Carcinoma Immunotherapy Through Synergistic Effects of Cuproptosis and PI3K Inhibitor Combination

Advanced Science, EarlyView.
ABSTRACT Cuproptosis, an emerging form of programmed cell death, is capable of inducing mitochondrial dysfunction. Moreover, the PI3K‐AKT‐mTOR signaling pathway contributes to tumor cell progression by reprogramming mitochondrial morphology and function.

Zinc Exposure Causes Disulfidptosis to Induce Miscarriage by Up‐Regulating GATA1/METTL1/SLC7A11 Axis

Advanced Science, EarlyView.
Zn exposure up‐regulates GATA1, promoting GATA1‐mediated METTL1 and SLC7A11 transcription. It also enhances METTL1‐mediated m7G modification on SLC7A11 mRNA, increasing SLC7A11 mRNA stability. Ultimately, Zn exposure up‐regulates SLC7A11 at both transcriptional and post‐transcriptional levels, causing disulfidptosis. Knockdown of murine Slc7a11, Gata1,

A spectrophotometric study of blood group A-specific substance isolated from hog gastric mucosa [PDF]

, 1948
A study of the ultraviolet absorption spectra of preparations of blood group A-specific substance isolated from hog gastric mucin supports the view that group A substance, and probably group O substance, has little specific absorption in this spectral ...

Endogenous “Time Bomb” – Mislocalized Phospholipase A2 as a Critical Mediator of Ultra‐Rapid Mortality in Sepsis and Acute Lung Injury

Advanced Science, EarlyView.
Phospholipase A2 (PLA2), a dormant enzyme, becomes lethal when activated—collapsing lungs in minutes. Our dual therapy (DOPS + varespladib) boosts survival from 0% to >90% in sepsis/ALI. A breakthrough for acute lung injury treatment. ABSTRACT This study reveals that phospholipase A2 (PLA2), normally stable and nontoxic, can be activated specifically ...
