Oncolytic Probiotics with Molecular Pili for Solid Tumor Therapy

open access: yesAdvanced Science, EarlyView.
This study identifies Lactobacillus rhamnosus as an intrinsic oncolytic agent that triggers tumor metabolic collapse via calcium‐dependent ROS bursts. By chemically anchoring collagen‐targeting “molecular pili” to the bacterial surface, the engineered non‐transgenic probiotic (LR@MP) achieves targeted colonization and potent solid tumor suppression ...

Identification of A p300–SP1–BRD4 Transcriptional Axis as a Key Driver of AR Hyperactivation in Polycystic Ovarian Syndrome

open access: yesAdvanced Science, EarlyView.
This study reveals a pivotal epigenetic regulatory role for the histone acetyltransferase p300, demonstrating that its acetylation of histone 3 at lysine 18 and 27 (H3K18ac and H3K27ac), alongside the formation of the p300/BRD4/SP1 complex, drives AR activation and ovarian fibrosis in PCOS.

Iron Oxide Nanozyme as Reactive Oxygen and Nitrogen Species Scavenger to Regulate Microglial Homeostasis in Stroke

open access: yesAdvanced Science, EarlyView.
6 nm iron oxide nanoparticles (IONP6) exhibit enzyme‐like activities that scavenge reactive oxygen and nitrogen species (RONS), including nitric oxide (NO). In stroke models, IONP6 promotes microglial polarization toward the M2 phenotype, reduces neuroinflammation, and improves neurological outcomes, offering a promising drug‐free approach to mitigate ...

A BioLiving Periosteum Evokes Centripetal Regeneration in Challenging Bone Defects

open access: yesAdvanced Science, EarlyView.
Large bone defects often suffer from insufficient central healing. This study engineers a BioLiving periosteum that mimics the native structure. It sequentially delivers remote chemical cues and contact physical cues in a signaling‐relay manner, effectively recruiting and guiding endogenous cells toward the defect center.

Universal Antibody‐Engineered Lipid Nanoparticles Potentiate Chemo‐Immunotherapy Against Triple‐Negative Breast Cancer by Reprogramming Tumor Cell Metabolism

open access: yesAdvanced Science, EarlyView.
A universal ROR1 antibody‐engineered lipid nanoparticle (LNP) is constructed by sequential drug encapsulation and antibody conjugation. The LNP not only enables enhanced chemotherapeutic efficiency by targeting drug delivery and precise localization of deep‐seated tumors through NIR‐II fluorescence imaging, but also remodels immunosuppressive TME ...

Elevated TRIM25 Impairs Poly (ADP‐ribose) Metabolism via PARG Degradation and Mediates Compression‐Induced Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
TRIM25 acts as a multifunctional hub driving intervertebral disc degeneration under mechanical stress. Mechanical compression significantly upregulates TRIM25 expression, establishing it as a key E3 ubiquitin ligase platform. TRIM25 targets PARG and Ku80 via distinct molecular interfaces, triggering their ubiquitination and degradation.

Immunomodulatory Fibrous Scaffold with Dual Enzyme‐Mimic Activities Prevents Postsurgical Tumor Recurrence

open access: yesAdvanced Science, EarlyView.
A MnOx nanozyme‐functionalized electrospun fibrous scaffold is developed for postoperative therapy by leveraging its intrinsic physicochemical and immunomodulatory properties. Integrating POD‐ and CAT‐like activities, the scaffold induces immunogenic cell death, alleviates hypoxia, and reverses immunosuppression, while simultaneously recruiting and ...

Direct Extracellular Matrix Modulation Attenuates Intestinal Fibrosis via a Fibronectin‐Targeted Approach

open access: yesAdvanced Science, EarlyView.
Fibronectin regulates the extracellular matrix (ECM)–myofibroblast cycle through three key steps: (1) its secretion and assembly by myofibroblasts (inhibited by pUR4); (2) collagen deposition along its scaffold (inhibited by R1R2); and (3) integrin α5β1‐mediated mechanotransduction (inhibited by ATN161).

RENAL‐CHIP: Rejection Evaluation via Non‐Invasive Analysis of Circulating Podocytes With Herringbone‐Chip Isolation Platform

open access: yesAdvanced Science, EarlyView.
RENAL‐CHIP converts 1 mL of peripheral blood into a biopsy‐equivalent readout of renal‐allograft fate. By magnetic capture and release of donor‐derived circulating podocytes through a herringbone microfluidic chip, 84% capture, 96% release and single‐cell RNA evidence of rejection‐specific immunity are achieved.
