Enhanced Selenium Supplement Extends Lifespan and Delays Multi‐Organs Aging by Regulating the Sik1 Pathway Through Maintaining Calcium Homeostasis

open access: yesAdvanced Science, EarlyView.
Aging involves physiological decline and heightened disease susceptibility, necessitating effective interventions. Redox‐responsive selenium‐loaded nanoparticles (SeMSNs) are developed, which delay cellular senescence by reducing oxidative stress and senescence markers (p16/p21). In aged mice, SeMSNs extend lifespan, improve organ function, and restore

Smoking‐Induced STC2+ Tumor Cells Drive Tumor‐Vascular Crosstalk in Laryngeal Squamous Cell Carcinoma via Spatial and Single‐Cell Transcriptomics

open access: yesAdvanced Science, EarlyView.
This study identifies a smoking‐induced mechanism in LSCC whereby nicotine activates the CHRNA5–JAK2/STAT3 axis to drive STC2 transcription. STC2 upregulates TGFBI, which interacts with endothelial ITGA5 to regulate vascular permeability and promote metastasis.

CypA Mediates Non‐Small Cell Lung Cancer Chemoresistance by Attenuating Ferroptosis via Stabilizing SLC7A11

open access: yesAdvanced Science, EarlyView.
Summary diagram for the role of CypA in chemoresistance in non‐small cell lung cancer (NSCLC). CypA is overexpressed in chemoresistance NSCLC and drives therapeutic evasion by competitively binding to the K37 site of SLC7A11, thereby blocking TRIM3 mediated K11‐linked ubiquitination and proteasomal degradation, ultimately inhibiting lipid peroxidation ...

Programmable Hydrogels: Frontiers in Dynamic Closed‐Loop Systems, Biomimetic Synergy, and Clinical Translation

open access: yesAdvanced Science, EarlyView.
This review summarizes the design principles and key features of programmable hydrogels that respond to multiple stimuli. It then delves into the cutting‐edge mechanisms of self‐executing systems, highlighting their role as the cornerstone of next‐generation programmable hydrogels (NGPHs).

Beyond Catalytic Therapy: Copper‐Paeonol Nanozymes Disrupt Fascin‐Mediated Actin Bundling to Suppress Tumor Growth and Metastasis

open access: yesAdvanced Science, EarlyView.
Copper‐paeonol nanozymes target tumor‐specific reactive oxygen species generation and disrupt fascin‐mediated actin bundling, effectively suppressing tumor growth and metastatic colonization. Abstract Fascin, an actin‐bundling protein universally upregulated in metastatic tumors, drives tumor migration and invasion by promoting filopodia and ...
