A ROS‐Responsive and Mucoadhesive Thermosensitive Hydrogel Encapsulated with Mizoribine for Synergistic Dry Eye Therapy

open access: yesAdvanced Science, EarlyView.
The ROS‐responsive in situ thermosensitive MZR@SPPP hydrogel system enables dual‐stage drug loading and sustained ocular delivery. Upon administration, it gelates at ocular surface temperature, enhancing ocular adhesion. By scavenging free radicals, restoring NRF2‐mediated antioxidant defense and mitochondrial homeostasis, and suppressing inflammatory ...

Epithelial SLC25A20 Deficiency Drives Immunosuppressive Neutrophil Remodeling via ARG1 Palmitoylation to Promote Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
SLC25A20 deficiency in tumor cells compromises mitochondrial LCFA transport, which suppresses FAO and drives compensatory release of palmitic acid‐enriched lipids into the TME. These tumor‐derived palmitic acids are taken up by TANs, promoting ZDHHC18‐catalyzed ARG1 palmitoylation.

Determination of Gene‐Level Fitness Contributions Across the Mucin‐Utilization Network of Bacteroides thetaiotaomicron

open access: yesAdvanced Science, EarlyView.
Genome‐wide CRISPRi and RNA‐seq resolve how B. thetaiotaomicron converts host mucosal glycans into fitness. The study reveals a layered mucin‐utilization architecture in which capsular polysaccharides constrain surface access, extracellular CAZymes and peptidases show functional redundancy, and intracellular catabolic pathways create discrete metabolic

Bioengineered Stroma‐Camouflaged Nanovesicles Disrupt the IDO1/CD276 Immunosuppressive Circuit to Reinvigorate Antitumor Immunity

open access: yesAdvanced Science, EarlyView.
Bioengineered stroma‐camouflaged nanovesicles (AM@UIO‐BMS/DOX) convert the immunosuppressive tumor niche into an immunoresponsive milieu by disrupting the IDO1/CD276 circuit. Anti‐CD276 membrane camouflage guides tumor accumulation and deep penetration, enabling controlled co‐delivery of DOX and the IDO1 inhibitor BMS‐986205.

Lactate‐H3K18la‐RPL11 Axis Drives Gemcitabine Resistance in Pancreatic Cancer by Integrating Protein Synthesis and DNA Damage Repair

open access: yesAdvanced Science, EarlyView.
A lactate‐H3K18la epigenetic axis upregulates RPL11 to drive gemcitabine resistance in pancreatic cancer. RPL11 orchestrates chemoresistance through a dual, compartmentalized role: enhancing cytoplasmic protein synthesis via EEF1A1 stabilization and promoting nuclear DNA damage repair by co‐activating PARP14, thus ensuring robust cell survival ...

Low‐Density Lipoprotein Receptor‐Targeted Biomimetic Nanoplatform Suppresses Glioblastoma Stemness and Remodels Antitumor Immunity via Dual Metabolic Disruption

open access: yesAdvanced Science, EarlyView.
A low‐density lipoprotein receptor‐oriented biomimetic nanoplatform couples brain‐tumor delivery with a mechanistically matched regorafenib‐erythrodiol combination. Concurrent disruption of autophagic nutrient salvage and cholesterol homeostasis collapses bioenergetic and signaling support, suppresses glioblastoma stemness, and promotes immunogenic ...

Nuciferine Suppresses Inflammatory Hepatocarcinogenesis by Targeting cPLA2‐Dependent Arachidonic Acid Metabolism

open access: yesAdvanced Science, EarlyView.
Nuciferine directly binds the C2 domain of cPLA2, impairing its Ca2+‐dependent membrane translocation and activation. By suppressing arachidonic acid release and downstream pro‐inflammatory eicosanoid production, nuciferine attenuates NF‐κB signaling and inflammatory hepatocarcinogenesis, revealing cPLA2 as a direct molecular target underlying its ...

Hepatic Lipid Stress Drives Metabolic Dysfunction‐Associated Steatohepatitis Progression through FTO O‐GlcNAcylation‐Induced m6A Demethylation of HRAS

open access: yesAdvanced Science, EarlyView.
Lipid stress drives O‐GlcNAcylation of the m6A demethylase FTO at Ser195, enhancing its stability and demethylase activity. This modification removes m6A from HRAS mRNA, preventing its degradation and activating PI3K/AKT signaling to promote hepatic steatosis and inflammation.
