Anti‐Inflammatory Mechanisms of Selenium Nanosheets in Ulcerative Colitis: Protein Corona, GP130 Interaction, and Transcriptomic Profile

Advanced Science, EarlyView.
SeNSs provide a biocompatible, anti‐inflammatory UC therapy. SeNSs form protein coronas enriched with AKT/PI3K/NF‐κB pathway proteins, suppress GP130 via hydrophobic interactions, and inhibit pro‐inflammatory cytokines. In DSS‐induced UC mice, SeNSs reduce inflammation, tissue damage, and disease activity by modulating cytokine, chemokine, and ...

Glycolytic Enzyme HK2 Phosphorylates nSMase1 to Promote Astrocytic Exosomes Biogenesis Contributing to Acute Ischemic Stroke Injury

Advanced Science, EarlyView.
This study reveals that the glycolytic enzyme HK2 mediates hypoxia‐induced astrocytic exosome biogenesis by directly phosphorylating nSMase1. These astrocytic exosomes impair brain endothelial tight junctions. Astrocyte‐specific knockdown of HK2 reduces exosome release and alleviates brain injury after MCAO.

Gasdermin D‐Mediated Pyroptosis Exerts Two Opposite Effects of Resisting Enzymatic Digestion and Expanding Inflammatory Response in Acute Pancreatitis

Advanced Science, EarlyView.
Gasdermin D (GSDMD) does not only reduce pancreatic enzyme synthesis but also induces pancreatic acinar cells to express mucin 1 (MUC1), which forms a barrier to prevent digestive enzyme‐mediated digestion. However, GSDMD can promote the secretion of inflammatory cytokines by macrophages and aggravate pancreatic histological injury by expanding ...

A Novel Cultivation System for Germ Cell Proliferation and Sustaining Whole Testicular Niche

Advanced Science, EarlyView.
A hydrogel microneedle‐based system enables whole testicular cultivation, supporting spermatogonial proliferation and enhancing spermatogenesis in vitro. This ‘whole testicular spermatogonia pool’ (WTSP) significantly increases spermatid production and fertility potential in mice. This system also promotes spermatogonial expansion in human fetal testes,

Inhibition of RNase to Attenuate Fungal‐Manipulated Rhizosphere Microbiome and Diseases

Advanced Science, EarlyView.
Fusarium graminearum uses its virulence effector Fg12, a fungal RNase, to manipulate the host rhizosphere microbiome and promote infection. Guanosine monophosphate (GMP) blocks Fg12's RNase activity. This reveals a key pathogen‐microbiota interaction mechanism and proposes GMP as a targeted strategy to disarm this core fungal effector, offering a ...

Lipid Droplet‐Organized MDM2‐Mediated P53 Degradation: A Metabolic Switch Governing Diet‐Driven Tumor Progression

Advanced Science, EarlyView.
Tumor‐associated TP53 inactivation correlates with lipid droplet (LD) accumulation. High‐fat diets drive Cyb5r3‐Myh9‐mediated p53 enrichment on LD surfaces, accelerating its degradation while upregulating LD‐promoting factor CD36 expression to establish a feed‐forward loop. LD suppression or dietary intervention restores p53 and inhibits tumorigenesis,

A Two‐Component Pseudo‐Icosahedral Protein Nanocompartment with Variable Shell Composition and Irregular Tiling

Advanced Science, EarlyView.
The structure and assembly principles of a two‐component encapsulin nanocompartment shell are reported. The two‐component protein compartment self‐assembles from two distinct HK97‐fold shell proteins into a pseudo‐icosahedral protein shell with variable composition and irregular tiling.

STK25 Loss Augments Anti‐PD‐1 Therapy Efficacy by Regulating PD‐L1 Stability in Colorectal Cancer

Advanced Science, EarlyView.
This study demonstrates that STK25 depletion facilitates CRC immune escape through the inhibition of PD‐L1 Ser283 phosphorylation‐mediated ubiquitination, and promotes tumor growth. Furthermore, these findings identify STK25 as a potential therapeutic target to trigger antitumor immunity and promote immunotherapy efficacy. Abstract Tumor immune evasion
