Chitosan‐Carbon Dot Composite Materials Form a Leaf Surface Barrier to Mitigate the Enrichment and Invasion of Nanoplastics: From Leaf Interface to Systemic Response

open access: yesAdvanced Science, EarlyView.
Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.

Drug‐Induced Cuproptosis Defines the Therapeutic Window of Celecoxib in Intervertebral Disc Degeneration via the HSP90‐RBX1 Axis

open access: yesAdvanced Science, EarlyView.
This study reveals the dual role of celecoxib in intervertebral disc degeneration. While low concentrations are protective, high concentrations induce toxicity by upregulating HSP90, which synergizes with USP15 to deubiquitinate and stabilize RBX1. This leads to degradation of COMMD1/ATP7B, copper dyshomeostasis, and ultimately, cuproptosis.

A Bone Marrow–Mimetic Hydrogel Enables Dual‐Phase Hemostasis and Vascularized Osteogenesis for Cranial Defects

open access: yesAdvanced Science, EarlyView.
A biomimetic, fiber‐reinforced hydrogel (FE‐PDA@Fib/Gel‐TG) that enables dual‐phase cranial defect repair. The system provides: instant hemostasis in the early stage, and sustained co‐delivery of pro‐angiogenic and osteogenic signals for synergistic vascularized bone regeneration.

Engineered Carbon Dots from a Traditional Herb Pair Orchestrate Concurrent Antioxidant and AP‐1‐Mediated Inflammation to Attenuate Renal Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
This study integrates two complementary traditional Chinese medicine components as precursors to synthesize bioactive AM‐AS@CDs. Compared with single‐component CDs, these dual‐component CDs exhibit enhanced antioxidant capacity and superior renoprotective effects.

PIEZO1 is Required for Acute Myeloid Leukemia Progression and Leukemia Stem Cell Maintenance via HIF1A‐SLC7A11 Axis‐Mediated Ferroptosis Defense

open access: yesAdvanced Science, EarlyView.
This study identifies the mechanosensor PIEZO1 as a key factor in promoting acute myeloid leukemia progression and uncovers a ferroptosis defense system mediated by PIEZO1‐HIF1A‐SLC7A11 axis that is essential for leukemia stem cell maintenance. This ferroptotic defense system may represent a unique vulnerability for leukemia stem cells, providing a ...
