From De Novo Conceived Small Molecules to Multifunctional Supramolecular Nanoparticles: Dual Biofilm and T3SS Intervention, Enhanced Foliar Affinity, and Effective Rice Disease Control

Advanced Science, EarlyView.
From de novo engineered bioactive molecules BtP27 to the multifunctional supramolecular material BtP27@β‐CD with a sunflower‐shaped morphology: its pragmatic applications in augmenting foliar affinity, disrupting biofilms and T3SS, and managing rice pathologies. Abstract Conventional antimicrobials typically exhibit suboptimal deposition on rice leaves,

Manganese Superoxide Dismutase Overexpression Attenuates MPTP Toxicity

Neurobiology of Disease, 1998
There is substantial evidence implicating mitochondrial dysfunction and free radical generation in the neurotoxicity of MPTP. Manganese superoxide dismutase (MnSOD) is the primary antioxidant enzyme protecting against superoxide radicals produced within ...

Tumour suppressor SIRT3 deacetylates and activates manganese superoxide dismutase to scavenge ROS

EMBO Reports, 2011
Mitochondria manganese superoxide dismutase (SOD2) is an important antioxidant enzyme, deficiency of which is associated with various human diseases. The known primary regulation of SOD2 is through transcriptional activation. Here, we report that SOD2 is

Orally Administered Functional Polyphenol‐Nanozyme‐Armored Probiotics for Enhanced Amelioration of Intestinal Inflammation and Microbiota Dysbiosis

Advanced Science, EarlyView.
This study presents a novel polyphenol‐nanozyme‐armored probiotic system (ECA@EcN) for enhanced treatment of inflammatory bowel disease (IBD). By integrating chitosan‐modified epigallocatechin gallate (EGCG‐CS) with gold nanozymes, the system effectively scavenges ROS, improves probiotic viability, and restores gut microbiota balance.

Simultaneous Monitoring of Tyrosinase and ATP in Thick Brain Tissues Using a Single Two‐Photon Fluorescent Probe

Advanced Science, EarlyView.
A single dual‐emission two‐photon fluorescent probe is designed for simultaneously tracking tyrosinase (TYR) and adenosine triphosphate (ATP). With the help of this probe, the intricate correlation and regulatory mechanism between TYR and ATP during oxidative stress is uncovered.

SENP3 Drives Abdominal Aortic Aneurysm Development by Regulating Ferroptosis via De‐SUMOylation of CTH

Advanced Science, EarlyView.
In this study, it is proposed that SENP3 accumulates in macrophages of aneurysmal aortic tissues, which promotes macrophage ferroptosis and inflammation via regulation of CTH de‐SUMOylation. Abstract Abdominal aortic aneurysm (AAA) is a high‐risk inflammatory disorder. SENP3, a SUMO2/3‐specific protease, is closely involved in the development of cancer.
