DDAH1 Promotes Cisplatin Chemoresistance in Patients with Locally Advanced Nasopharyngeal Carcinoma via the EGFR‐JAK2‐STAT3 Pathway

open access: yesAdvanced Science, EarlyView.
This study identifies a novel mechanism of nasopharyngeal carcinoma (NPC) cisplatin chemoresistance that DDAH1 expression is associated with cisplatin resistance in NPC cells primarily through the enhancement of the phosphoinositide Janus kinase 2 (JAK2)‐signal transducer and activator of transcription 3 (STAT3) pathway.

Bioinspired Claw‐Engaged Adhesive Microparticles Armed with γGC Alleviate Ulcerative Colitis via Targeted Suppression of Macrophage Ferroptosis

open access: yesAdvanced Science, EarlyView.
γGC deficiency in ulcerative colitis drives macrophage ferroptosis‐mediated inflammation. Claw‐engaged microparticles armed with γGC (γGC‐MPs) enhance lesion targeting, promoting localized γGC release and tissue uptake. On the cover, Monkey King (Macrophages) was bound by the Immortal‐Binding Rope and subsequently sealed beneath the Five‐Fingered ...

DNA Origami‐Based CD44‐Targeted Therapy Silences Stat3 Enhances Cartilage Regeneration and Alleviates Osteoarthritis Progression

open access: yesAdvanced Science, EarlyView.
This study develops a cartilage‐targeted DNA origami system (OCS) that protects and delivers si‐Stat3 to chondrocytes. OCS reduces MMP13 expression, enhances extracellular matrix stability, and lowers oxidative stress while improving cell survival. In vivo, OCS decreases cartilage degradation biomarkers and promotes tissue repair factors, demonstrating

Neutrophil‐Mimicking Nanomedicine Eliminates Tumor Intracellular Bacteria and Enhances Chemotherapy on Liver Metastasis of Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
Fusobacterium nucleatum (Fn) enrichment has been identified in colorectal cancer and its liver metastases. This study develops neutrophil‐mimicking nanoparticles with multiple targeting capabilities encapsulating metronidazole and oxaliplatin for antibacterial and anticancer purposes. This approach reverses the epithelial mesenchymal transition process

Brachyury‐Activated Fucoidan Hydrogel Microspheres Rejuvenate Degenerative Intervertebral Discs Microenvironment

open access: yesAdvanced Science, EarlyView.
This study describes the creation of injectable Brachyury (Bry) mRNA‐loaded Fucoidan‐functionalized GelMA hydrogel microspheres (BLNP@GF). These microspheres efficiently suppress inflammation, enhance extracellular matrix (ECM) synthesis in degenerated nucleus pulposus cells, and mitigate intervertebral disc degeneration (IVDD) in rat models.

Human iPSCs Derived MSCs‐Secreted Exosomes Modulate Senescent Nucleus Pulposus Cells Induced Macrophage Polarization via Metabolic Reprogramming to Mitigate Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
Senescent nucleus pulposus cells drive inflammatory M1 macrophage polarization, exacerbating intervertebral disc degeneration (IDD). Conversely, M1 macrophages accelerate NP cell senescence, creating a vicious cycle. iPSCs‐derived mesenchymal stem cell (iMSCs) exosomes break this loop by delivering miR‐100‐5p to suppress mTORC1/glycolysis in ...
