Macrophage‐Mediated Transport of Insoluble Indirubin Induces Hepatic Injury During Intestinal Inflammation

Advanced Science, EarlyView.
Plant‐derived bioactive molecules with low solubility and permeability induce hepatocyte injury, though the mechanisms driving their hepatic effects remain poorly understood. This study identifies a novel transport pathway in which poorly soluble indirubin accumulates in the liver via macrophage‐mediated uptake in Peyer's patches, exacerbating hepatic ...

Lipid Droplet‐Organized MDM2‐Mediated P53 Degradation: A Metabolic Switch Governing Diet‐Driven Tumor Progression

Advanced Science, EarlyView.
Tumor‐associated TP53 inactivation correlates with lipid droplet (LD) accumulation. High‐fat diets drive Cyb5r3‐Myh9‐mediated p53 enrichment on LD surfaces, accelerating its degradation while upregulating LD‐promoting factor CD36 expression to establish a feed‐forward loop. LD suppression or dietary intervention restores p53 and inhibits tumorigenesis,

Coordination Geometry Tuning in a Single‐Atom Nanozyme to Mimic Metalloenzymes with Nonplanar Active Site

Advanced Science, EarlyView.
Correlation between coordination geometry and catalytic activity of carbonic anhydrase‐mimetic single‐atom Zn–N4 active sites is revealed. Among tetrahedral, distorted tetrahedral, and square‐planar Zn–N4 geometric configurations, the distorted tetrahedral Zn–N4 exhibits superior CO2 hydrolysis performance. This is attributed to increased Lewis acidity,

Binding of arylazidocytochrome c to yeast cytochrome c peroxidase.

Journal of Biological Chemistry, 1981
Cytochrome c derivatives modified with a photoactivatable arylazido group in selected lysine residues were irradiated in the presence of cytochrome c peroxidase (EC 1.11.1.5). A derivative modified at lysine 13 was able to cross-link to the enzyme and inhibit electron transfer activity.

A Needle‐Like H2S‐Releasing and H2O2 Self‐Replenishing Nanoplatform for Enhanced Chemodynamic Tumor Immunotherapy

Advanced Science, EarlyView.
The PTA‐SnS2@GOx cascade nanosystem presents a smart paradigm for cancer theranostics, integrating self‐supplied H2S/H2O2‐augmented chemodynamic therapy (CDT) with sensitized immunotherapy. Its needle‐like SnS2 shell enhances tumor‐specific uptake, ensuring biosafety.

Cocrystals of yeast cytochrome c peroxidase and horse heart cytochrome c.

Journal of Biological Chemistry, 1987
Yeast cytochrome c peroxidase and horse heart cytochrome c have been cocrystallized in a form suitable for x-ray diffraction studies and the structure determined at 3.3 A. The asymmetric unit contains a dimer of the peroxidase which was oriented and positioned in the unit cell using molecular replacement techniques.

Harnessing the Biological Responses Induced by Nanomaterials for Enhanced Cancer Therapy

Aggregate, EarlyView.
Nanomaterial (NM)‐induced toxicity can be strategically repurposed for cancer therapy. This review summarizes the mechanism by which NMs selectively activate specific cellular processes to regulate cell fate independently. We also discussed how NMs‐induced biological responses can be leveraged as therapeutic strategies for cancer treatment.

The Multifaceted Etiology of Mental Disorders With a Focus on Trace Elements, a Review of Recent Literature

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Mental disorders are a significant global public health concern, affecting nearly one in eight individuals worldwide. This review investigates the multifaceted etiology of mental disorders—specifically major depressive disorder (MDD), schizophrenia (SCZ), and bipolar disorder (BD)—through genetic, neurobiological, and environmental ...

Cellular and Molecular Evidence of Acetaldehyde Elimination and Intracellular Environment Antioxidation by L-Cysteine

Journal of Chemistry, 2018
Acetaldehyde is a harmful metabolite of smoking and drinking. This study was initially intended to facilitate the understanding of the possible injury mechanism of A549 cells damaged by acetaldehyde and the possible protective mechanism of L-cysteine (L ...
